29 Frequently Asked Questions Transbond MIP Moisture Insensitive Primer Transbond MIP Moisture Insensitive Primer Back to Directory 3Unitek Products that make your life easier.

30 Transbond MIP Moisture Insensitive Primer Frequently Asked Questions 1. What does Moisture Insensitive Primer mean? Literally, it means not physically or chemically sensitive to small quantities of moisture. Clinically, it means after rinsing and thoroughly removing etchant, drying of tooth surface before priming is not required. 2. What will happen if I apply Transbond MIP moisture insensitive primer to dry teeth? Bond strength will not be affected. 3. Should I dip the applicator in the Transbond MIP primer before coating each tooth? Yes. Dip applicator and completely saturate the brush tip in the primer before coating each tooth to ensure adequate coverage of etched surface. Adequate coverage is necessary to ensure bond strength. 4. What if there is water/saliva contamination after the application of the Transbond MIP primer? If bonding is delayed and moisture contamination occurs after the application of primer to the tooth surface, apply one more fresh coat of primer over the contaminated area, blow air for 2-5 seconds and bond immediately. 5. Why should I blow air on each tooth for 2-5 seconds after applying the Transbond MIP primer? Blowing air for 2-5 seconds helps force the primer into the enamel rods and distributes the primer evenly, ensuring adequate bond strength. Ethanol is also evaporated. 6. Is Transbond MIP primer compatible with all Transbond light cure adhesives? Yes. Transbond MIP primer works with Transbond XT and LR capsules, Transbond XT syringes, and APC PLUS Adhesive Coated Appliance System. 7. Is Transbond MIP primer compatible with the chemical cure adhesives? Yes. Transbond MIP primer has been qualified for both Concise and Unite Chemical Cure Adhesives as well as Sondhi Rapid-Set Indirect Bonding Adhesive. Please follow the Instructions for each of the above mentioned adhesives.

31 Frequently Asked Questions Transbond Plus Self Etching Primer Transbond Plus Self Etching Primer Back to Directory 3Unitek Products that make your life easier.

32 Transbond Plus Self Etching Primer Frequently Asked Questions 1. Why is the liquid tinted pale yellow? Camphorquinone (CPQ) causes the pale yellow tint. Therefore, after proper activation, the saturated applicator fiber tip will look pale yellow. CPQ is only contained in the outer large blister. If the contents of the first blister do not properly mix with the contents of the middle blister or if the applicator tip is not saturated with the properly mixed liquid, then the applicator tip will look clear. 2. Is this product moisture tolerant? Yes, it contains a hydrophilic component which tolerates small amounts of moisture. 3. Why is this technique so different from what has been taught about applying traditional etchants? This product uses a different chemistry and technology for etching teeth and is different from the traditional phosphoric acid etchants. Traditional etchants are lightly painted on the enamel without rubbing. Transbond Plus Self Etching Primer must be RUBBED onto the enamel for 3 to 5 seconds in order to continue the etching process. This product will not etch properly if it is applied using the traditional phosphoric acid etchant technique. 4. Why should the material be rubbed on the enamel for 3 to 5 seconds? RUBBING the material on the enamel delivers unreacted etchant/primer molecules to the enamel surface as they are depleted. It is very important to not just paint the product on the enamel but RUB it onto the enamel with some force. This technique actually helps with the etching process. 5. Will rubbing this product for 3 to 5 seconds damage the enamel rods? No. See etch pattern SEMs on the product brochure. 6. How can one product work as both etchant and primer? The chemistry used in this product consists of a bifunctional molecule on a methacrylate base. When RUBBED onto the enamel, the etchant component will expose the enamel rods while the primer components simultaneously penetrate into those exposed rods. 7. How does the etch pattern using Transbond Plus Self Etching Primer compare to the etch pattern using phosphoric acid? The etch pattern using this product is well defined and comparable to traditional phosphoric acid etchants. See SEM comparisons of the two etch patterns in the product brochure. One of the advantages of this system is that demineralization and resin penetration occur concurrently, therefore, the etching depth and the resin penetration depth are identical. 8. How many teeth can be etched and primed with one disposable unit? One unit contains enough material for bonding one arch. 9. How long can the etchant/primer be left on the tooth before bonding? After applying the etchant/primer and delivering a gentle air burst, the tooth is ready to be bonded. Bonding can be delayed for up to 2 minutes if the tooth has not been contaminated with moisture or saliva. If bonding is delayed for more than 2 minutes or moisture/saliva contamination is imminent, then another application of etchant/primer and gentle air burst is recommended. 10. What happens to the debris or the residue after etching? The residue produced during the etching process is either blown away with the excess primer (during the air burst step) or is incorporated into the matrix during light curing. This process does not affect bond strength. 11. How will I know that sufficient etching has been achieved? Will a frosty look appear on the enamel? No. The enamel will not look frosty white. It should however look uniformly shiny after the gentle air burst step. Also, enamel ridges may be visible on the etched surfaces. 12. How will I know that the etchant has been inactivated? Inactivation occurs after etchant is light cured. 13. Why is a 2-second air burst required after rubbing the Transbond Self Etching Primer onto the tooth surface? The 2-second airburst is necessary to thin out the primer on the tooth surface and evaporate the water component to ensure good bond strength. 14. What will happen if the air burst step is not delivered? Will the product overetch? The unique properties of the primer cause the etching to slow when rubbing is stopped; the tooth will not over-etch. However, bond strengths will be lower if the 2-second airburst is not delivered. 15. What will happen if the gentle air burst is delivered toward the gingiva? This product is corrosive. It also contains methacrylates which in some patients can cause sensitive or allergic reaction if the chemical contacts tissue. Therefore, when delivering the air burst after the etching process, it must be a gentle air stream directed away from the gingiva. B O N D I N G R E F E R E N C E G U I D E

33 16. Can this material cause sensitivities? The product contains methacrylated phosphoric acid esters. Contact with skin or mucous membranes may cause irritation or allergic reaction in some individuals. Gloves must be worn when handling this product. Thoroughly rinse accidentally exposed areas with water. Contact a physician if irritation persists. 17. What will happen if the primer is light-cured after the gentle air burst step, but before bonding? Light-curing before bonding will not lower bond strength, however, it is not necessary. 18. Why does the applicator have to be inserted back into the reservoir before each application? The applicator has to be inserted into the reservoir before applying on each tooth so that it can be saturated with a fresh supply of the material. 19. Can this product be used with metal and ceramic brackets? Yes. Follow bracket manufacturers recommendations for use. 20. Can this product be used with indirect bonding if only light-cured adhesives and resins are used? It is not recommended to use this product for indirect bonding because the bond strengths are lower. 21. Is Transbond Plus Self Etching Primer fluoride-releasing? Yes, it contains and releases fluoride. 22. Is there a bond strength difference between bonding to dry vs. moist teeth? No. Bond strength is similar whether the product is applied to dry or moist teeth. 23. Does the adhesive need to be refrigerated when not in use? No. However, the product must be protected from excessive heat and light before activation. 24. What is the shelf life of Transbond Plus Self Etching Primer? The shelf life of the product is 18 months from date of manufacture. The product expiration date is printed on the packaging. 25. Can a halogen light be used for curing this product? Yes, halogen lights covering the nm range can be used for curing Transbond Plus Self Etching Primer. 26. Can a plasma arc or laser curing light be used with this product? Testing has been done in the lab using the ORTHO Lite Quick Curing Light (plasma arc). The testing showed good bond strength with the light. Testing has not been performed on other plasma and laser lights in the marketplace, we do not recommend using this product with these lights. 27. Can an LED curing light be used with this product? Yes, testing has been done in the lab using the Ortholux LED Curing Light. The testing showed good bond strength with the light. The formulation contains camphorquinone (CPQ). CPQ is the photoinitiator in most light-curable adhesives and primers. This enhances the compatibility of Transbond Plus SEP with most light-curing systems. 28. Can the applicator be bent? Yes. The applicator is bendable at the tip so that it can be used at any angle to facilitate application. 29. If there is enough material left in the blister can it be used for rebonding another patient? No. Do not use one unit on two patients. Doing so will cause cross contamination. 30. What solvent is used in this product? Water is the only solvent used in this product. 31. Does this product contain a filler? No, it does not contain any filler. 32. Can this product be used with Unite Adhesive, Concise Adhesive or Sondhi Indirect Resin A and B? Results indicated lowered bond strengths with all chem-cure adhesives. Therefore, we do not recommend this product be used with these adhesives. 33. How can I clean instruments or clothing if the material is accidentally spilled? It is best to wash instruments or clothing immediately if accidentally contaminated with uncured material. Cured material can be very difficult to remove. Ethanol may be useful for cleaning dried materials. Rinse skin and eyes immediately in case of accidental exposure.

34 Frequently Asked Questions Transbond Plus Light Cure Band Adhesive / Multi-Cure Glass Ionomer Band Cement Band Adhesives Back to Directory 3Unitek Products that make your life easier.

35 Band Adhesives Frequently Asked Questions 1. What is the purpose of a band adhesive? The purpose of a band adhesive is to act as a grout to fill the irregularities between the band and the tooth surface. 2. Why is Unitek Multi-Cure Glass Ionomer band cement stronger than Transbond Plus light cure band adhesive? Unitek Multi-Cure band cement is stronger because it provides both chemical and mechanical adhesion to both the band and enamel surface of the tooth. 3. Under which conditions would I need the extra strength of Unitek Multi-Cure GI band cement? In some offices the extra adhesion offered by a glass ionomer is a welcome advantage where bands fit poorly, where there are isolation issues and in situations where forces greater than those normally exerted from headgear and rapid palatal expanders are expected. The trade-off is increased mixing time, increased clean-up time and increased difficulty when removing the cement from the teeth. 4. Under which conditions would I want to use Transbond Plus light cure band adhesive? In offices where band fit, moisture control and loose bands are not an issue. In these offices, Transbond Plus band adhesive is the best choice for ease-of-use and ease of clean-up. 5. What is the effect of moisture on Unitek Multi-Cure band cement & Transbond Plus light cure band adhesive? Hybrid glass ionomers, like Unitek Multi-Cure band cement, work best on a moist surface; however, glass ionomers do not tolerate additional water/saliva introduced during the curing process. Compomers, like Transbond Plus band adhesive, are not as tolerant of moisture as glass ionomers. An effort should be made to keep the tooth dry when using Transbond Plus band adhesive. 6. Will decreasing the time I light cure Transbond Plus band adhesive affect band retention? Yes, Transbond Plus band adhesive must be cured for the full 30 seconds since there is not a chemical cure component to this adhesive. Archwires may be placed immediately after curing. 7. Will decreasing the time I light cure Unitek Multi-Cure GI band cement affect band retention? No, since the Unitek Multi-Cure band cement also cures chemically, band strength will not be affected if archwires are not placed for 5 minutes. Five minutes is the minimum time needed for the adhesive to fully set-up chemically. If the Unitek Multi-Cure band cement is light cured for the full 40 seconds, archwires can be placed immediately. 8. Should I consider using both Transbond Plus light cure band adhesive and Unitek Multi-Cure band cement in my orthodontic practice? Each product provides unique advantages to different banding situations. In some circumstances, one may be more suitable than the other, making both valuable tools in the orthodontic practice.

36 Frequently Asked Questions APC PLUS Adhesive Coated Appliance System APC PLUS Adhesive Coated Appliance System Indirect Bonding APC PLUS System Back to Directory 3Unitek Products that make your life easier.

37 APC PLUS Adhesive Coated Appliance System Frequently Asked Questions 1. Is the color of the adhesive a curing indicator? A. No, the color change does not indicate curing of the adhesive. Under ambient light, the pink color fades away several minutes before the adhesive cures. 2. Is the consistency of APC PLUS Adhesive comparable to APC II Adhesive? A. The consistency of APC PLUS adhesive has been engineered to be very closely matched with that of APC II adhesive. You might find, however, that APC PLUS adhesive is slightly tackier. 3. After seating APC PLUS system brackets, is there a way to slow the fading of the pink color? A. Yes, covering the patient s mouth with a dark cloth will retard the fading of the pink color. 4. Can the colored APC PLUS adhesive stain the teeth? A. No, APC PLUS adhesive bleaches with light exposure and will not stain teeth. 5. What is the filler material in APC PLUS adhesive? A. The filler material is a mixture of quartz, fumed silica, and fluoride-containing glass. 6. Can I move the bracket after seating but before curing? A. Once the bracket has been seated, the adhesive is squeezed out. If the bracket is moved at this point, there may not be complete adhesive coverage under the bracket, which may result in bond failure or decalcification. To ensure complete coverage, remove the bracket, apply additional Transbond XT Adhesive and proceed as usual with your bonding steps. 7. What is the difference in bond strength between APC II adhesive coated brackets and APC PLUS adhesive coated brackets? A. Both APC II adhesive coated brackets and APC PLUS adhesive coated brackets provide clinically acceptable shear bond forces when used with either ceramic or metal appliances. 8. Do APC PLUS adhesive coated ceramic and metal brackets cure in the same time as APC II system brackets? A. Yes, APC PLUS and APC II adhesive coated brackets cure in the same amount of time, and using the same methods. See Figure How is APC PLUS adhesive cured? A. APC PLUS adhesive contains camphorquinone (CPQ) and is cured by visible light emitting at a wavelength of approximately 475 nanometers. 10. How long should I wait before placing the archwire? A. The archwire can be placed immediately after curing all brackets. 11. My APC PLUS system brackets were exposed to F (32-38 C) temperatures for a short period of time. Are they still okay? A. Yes, temperature elevation for a period of 2-3 hours will not affect shelf life or effectiveness of the adhesive on the bracket as long as it was not exposed to bright light, and it is allowed to reach room temperature prior to use. 12. Can I store APC PLUS system brackets in the freezer to extend shelf life? A. No, this system should not be frozen. If refrigerated, it is imperative that the bracket reaches room temperature (68-77 F) before use. Abrupt movement of the package when the adhesive is very cold can cause bracket displacement from the proper location in the blister.

38 13. How can I clean dried adhesive from instruments? A. It is best to clean instruments immediately after use. Adhesive remnants on instruments that are not completely cured can be cleaned by scraping the adhesive off the instrument, followed by cleaning with solvent or ultrasonically. However, if the adhesive is completely cured, it is very difficult to clean the instrument without damaging it. Cured adhesive may be carefully scraped off using another instrument. Take care not to scratch either instrument in the process. 14. Does APC PLUS adhesive contain fluoride? A. Yes, the APC PLUS adhesive does contain and release fluoride. 15. Is APC PLUS adhesive moisture tolerant? A. Yes, APC PLUS adhesive contains hydrophilic monomers and cured APC PLUS adhesive has an improved absorption of moisture compared to APC II adhesive. Using Transbond Plus Self Etching Primer or Transbond MIP Primer, both moisture-tolerant primers, along with APC PLUS system brackets will provide a complete moisture-tolerant bonding system. Note: Using a hydrophobic primer with the APC PLUS system brackets will not provide a moisture-tolerant system. 16.

39 Indirect Bonding Frequently Asked Questions 1. Does APC PLUS Adhesive have comparable bond strength to APC II Adhesive when using the indirect method? A. Yes. APC PLUS adhesive and APC II adhesive provide similar bond strength when used with the Sondhi Rapid-Set Indirect Bonding Adhesive System. 2. Are there any special requirements needed to prepare the stone model for use with APC PLUS adhesive? A. Following the Sondhi Indirect Bonding Technique*, after pouring the ortho stone into the impression, the model should be dried. This can be accomplished by drying overnight in an oven at 110 F (43 C), or under ambient conditions. Because of the hydrophilic nature of APC PLUS adhesive, using a damp model may negatively affect the curing of the custom resin base. 3. How important is the secondary curing of the brackets after removing the tray from the stone model? A. The primary curing of the adhesive, especially when metal brackets are used, on a stone model is never complete because of the opacity of the model. Therefore, it is strongly recommended that a 2-minute secondary cure of the custom resin base be performed by directly exposing the tray to the light source.* 4. After removing the tray from the stone model, rinsing, and drying, the APC PLUS adhesive resin appears cloudy white (Figure 1). What does this mean? A. The white color is caused by water interacting with a surface layer of hydrophilic APC PLUS adhesive resin. This very thin, white layer can be microetched or cleaned prior to bonding and should not present a problem. Figure 1: White layer on resin base. 5. I use Clarity Ceramic Brackets with APC PLUS adhesive for indirect bonding and do not observe a white layer over the custom resin base. Why? A. This white layer is less noticeable with ceramic brackets than with metal brackets because a more thorough cure is obtained during the primary cure with ceramic brackets. 6. How should the tray be prepared for bonding? A. Following the current technique, the custom resin base should be cleaned using a microetcher (50 micron alumina particles) by gently passing the nozzle over the custom resin bases and then rinsing with de-ionized water to remove residue (Figure 2). As with APC II adhesive, take care not to damage the custom resin base. Microetching may not completely eliminate the white layer, but will create a roughened surface for bonding. Figure 2: Tray after microetching. 7. Will microetching the white layer affect the custom resin base? A. No. The white surface comes from a thin layer covering the custom resin base. Lightly microetching will not damage the adhesive base and will ensure a roughened base for bonding. 8. I do not own or use a microetcher. How can I clean the custom resin base prior to bonding? A. If a microetcher is unavailable, thoroughly scrubbing the custom resin base with a toothbrush is also an effective cleaning method. Although the cloudy white layer may remain, adequate bond strength will be achieved. 9. What will happen if I bond using APC PLUS adhesive without microetching or cleaning the custom resin base? A. As with APC II adhesive, omitting the cleaning step may result in a reduction in bond strength. 10. Does APC PLUS Adhesive used for indirect bonding with the Sondhi Rapid-Set System have comparable bond strength to APC PLUS Adhesive used for direct bonding? A: Yes. APC PLUS Adhesive used with the Sondhi Rapid-Set System provides similar bond strength to direct bonding. B O N D I N G R E F E R E N C E G U I D E M Company.

40 Frequently Asked Questions Ortholux LED Curing Light Ortholux LED Curing Light Back to Directory 3Unitek Products that make your life easier.

41 Ortholux LED Curing Light Frequently Asked Questions Ergonomics 1. What is the proper way to hold the Ortholux LED curing light? A. The handpiece should be held like a pencil, as shown in the picture (ref. Figure 1). Figure 1 Battery 2. How many patients can be bonded with one full battery charge? A. Up to eight full 7x7 hook ups can be completed on one full charge. However, the unit will temporarily shut down to cool off after two to three consecutive full hook ups. 3. What should I do if the unit automatically shuts off for cool down? A. Place the handpiece back in its charger or table holder and wait for about 20 minutes for the LED light to cool before resuming use. 4. What about the memory effect? Should the light always be charging while not in use? A. For optimum performance, the nickel metal hydride battery should be conditioned over its first 3 charge/discharge cycles. To do this, completely charge the unit before initial use and then use the curing light, without intermittent charging until fully discharged (i.e. place the handpiece on the table holder instead of the charger). Repeat this 2 more times. After conditioning, the curing light may be charged or discharged at any time. 5. What is the lifetime of the battery? A. The nickel metal hydride battery is rated for approximately 10,000 total charges (both partial and full) before it needs to be replaced. This corresponds to about 2 years of use. LED 6. Does the Ortholux LED curing light emit ultraviolet (UV) light? A. No. The Ortholux LED curing light emits a visible blue light. 7. Is the Ortholux LED curing light a laser? A. No. It is a light emitting diode. The diode produces a high intensity blue light in the 430 to 480 nm wavelength range. 8. How does the Ortholux LED curing light cure so quickly? A. Light cure adhesives contain photoinitiators, such as camphorquinone (CPQ), that polymerize when exposed to light in the 430 to 480 nm wavelength range. Increasing the light intensity in this range speeds the polymerization process, resulting in a faster cure (ref. Figure 2). Spectral flux (mw/nm) 4.0 Ortholux LED 3.5 Camphorquinone Wavelength (nm) CPQ absorption Figure 2 9. How do I verify the light intensity? A. Simply use the light meter located near the base of the charging unit. Refer to the Instructions For Use ( ) for additional details. B O N D I N G R E F E R E N C E G U I D E 10. How consistent is the light intensity over repeated use? A. The light emitting diode intensity is engineered to be highly consistent over the operating lifetime of the diode. However, light intensity can be reduced by contamination or damage to the light guide and should be checked periodically using the built-in light meter.

42 11. What are the factory settings for light intensity? A. The light is set for an intensity of approximately 1000 mw/cm2. This cannot be changed. Curing Times 12. How long should I cure metal APC II Adhesive Coated Appliances or metal brackets coated with Transbond XT Adhesive? A. Metal brackets should be cured for 5 seconds mesial and 5 seconds distal (total 10 seconds) with the light guide held as close as possible without touching the teeth or appliances. Light source must be held steady while curing. For time efficiency, metal appliances can be cured at the interproximal contact of each tooth for 5 seconds, simultaneously curing the mesial and distal sides of two adjacent brackets. 13. How long should I cure ceramic APC II Adhesive Coated Appliances or ceramic brackets coated with Transbond XT Adhesive? A. Ceramic brackets should be cured for 5 seconds by placing the light guide perpendicular and 2mm above the bracket. Light source must be held steady while curing. 14. How long should I cure APC II Adhesive Coated buccal tubes or buccal tubes coated with Transbond XT adhesive? A. Buccal tubes should be cured for 10 seconds mesial and 10 seconds occlusal. Light source must be held steady while curing. 15. How long should I cure bands using Unitek Multi-Cure Glass Ionomer Band Cement or Transbond Plus Light Cure Band Adhesive? A. Bands should be cured for 5 seconds per cusp (total 20 seconds) with the light held on the occlusal. 16. Can the light be used to cure continuously? A. The light does not have a continuous curing mode. However, you can cure using the 20 seconds mode and the handpiece will beep every 5 seconds until the 20 seconds have elapsed. 17. How do bond strengths compare when using the Ortholux LED light versus a standard halogen curing light? A. Bond strengths are comparable refer to Figure 3 for a comparison of bond strengths after 24 hours. Figure Can I cure other adhesives and cements using the Ortholux LED curing light? A. Yes. Light cure adhesives containing photoinitiators such as camphorquinone that cure in the 430 to 480 nm wavelength range can be cured using this light. 19. What are the curing times for other light cure adhesives and cements? A. Reference adhesive and cement manufacturers instructions for curing times using LED curing lights. Maintenance 20. Which disinfectants can be used on the Ortholux LED light? A. The Ortholux LED light may be disinfected using standard surface disinfectants, including 3M TB Quat, DisCide Ultra, BIREX SE, Sani-Cloth Plus, and Cavicide disinfectant. 21. Why should I not spray directly onto the light and why should I wipe the light dry? A. If sprayed directly and if not wiped dry, the disinfectant may penetrate into the components and cause damage. The charging unit contact pins must be wiped dry. 22. How can I sterilize the light guide? A. Clean the tip before sterilization. Adhering polymerized composite can be removed with alcohol. Steam autoclave at 121 C (250 F) for 30 minutes. Allow light guide to cool for 20 minutes prior to handling. To prevent potential discoloration or damage, do not sterilize by chemical means or hot air. 23. Why should I always place the handpiece on the charger or table holder when not in use? A. The curing tip is made of glass and is fragile. If the handpiece is left on a tabletop or a hard surface, there is a possibility for it to drop or hit other hard surfaces and crack. Always ensure the handpiece is completely secure before moving, transferring the light or when not in use.
