FEATURES OF THE DIFFERENT PROSTHESETIC ACCESSORIES HEXED DRILLABLE ABUTMENTS The drillable abutment family is machined in titanium. It includes the following types of abutments:. Drillable abutments with 2 mm and 4 mm shoulder for all the BNT & TSH implants in series 2, 3, 4 and 5. The abutment retention screw is supplied separately.. Angulated 15 and 25 drillable abutments for BNT & TSH 3 and 4 implant series. They are supplied without transgingival height and with 1 mm transgingival height. They are supplied together with the retention screw. As their names indicates, drillable abutments are indicated to be drilled and modified as needed by the user in cemented restorations. The fixation torque for the retention screw is 35 N cm. INDICATIONS. In general for single and multiple cemented restorations over the abutment.. To level the crown emergence height in relation to the adjacent natural teeth and the thickness of the soft tissue:. If the occlusal height from the implant exceeds 6 mm.. If it is necessary to adjust the height of the antagonist and parallelise the prosthesis insertion axis.. In fixed restorations with disparellelism between implants.. In single or multiple restorations where, due to the position of the implant, the retention screw entry hole in a screwed prosthesis compromises the aesthetic outcome of the restoration. ADVANTAGES. Greater control of the aesthetic outcome of the prosthesis. PRECAUTIONS. Possibility of prolonged tissue reaction due to the cement used.. Retention of the prosthesis due to excess cement.. Less control of crown or bridge seating during the cementing process. CONTRAINDICATIONS. If the occlusal height from the implant platform is less than 4 mm. DIRECT UCLA CASTING TO IMPLANT The implant direct Casting cylinder family is machined in plastic. They are indicated for screwed single or multiple restorations or bar overdentures for the Phibo BNT & TSH system. The implant direct Ucla Casting cylinder family is comprised of: - Hexed Ucla casting cylinder: Indicated for single, screwed fixed crowns. -Non-hexed Ucla casting cylinder: Indicated for multiple fixed restorations or overdentures. The different types of casting cylinders in the Phibo BNT & TSH system are supplied apart from the retention screw, which is set at a 35 N cm torque. ADVANTAGES Easy prosthesis removal to make maintenance and hygiene easier during periodic check-ups. CONTRAINDICATIONS In cases in which the entry hole for the retention screw affects the aesthetics of the restoration. 5
BALL ABUTMENTS A ball abutment is a base abutment for performing restorations with implant-gingival-supported overdenture. The ball abutment is machined in titanium. Available for series 3 and 4 in the following sizes.. BNT & TSH series 3 implants: Abutments with 2 mm and 4 mm transgingival zone.. BNT & TSH series 4 implants: Abutments with 2 mm and 4 mm transgingival zone. The final implant insertion torque is 35 N cm. Maximum permitted angulation: 30º between implants. INDICATIONS. Ball abutment for performing restorations with implant-gingival-supported overdenture in the mandibular sector.. In cases with a significant mandibular elastic bone mass loss, where placement of implants for other types of restoration represents a high risk of bone fracture. ADVANTAGES. Allows you to perform restorations with overdenture.. The retention system is simple and reliable. RELATIVE CONTRAINDICATIONS. In the maxillary bone. As it is necessary to place a greater number of implants due to low bone density, adjusting the rebasing and the overdenture to the abutment is more complex.. In all cases where another type of restoration is indicated.. In restorations with more than two implants with severe disparallelism (as insertion of the prosthesis would be difficult). COMPLEMENTARY SUPERSTRUCTURES. Machined titanium sleeve with O-ring: Accessory that integrates with the lower part of the overdenture and holds it to the implant by connection to the ball abutment. The element that provides the sleeve-abutment retention function is a rubber O-ring seal seated inside the sleeve. IMPRESSION TAKING METAL TRANSFERS CHARACTERISTICS Accessories machined in titanium.. Available for open cuvette technique: metal transfer with long screw.. Available for closed cuvette technique: metal transfer with short screw.. The blister contains: impression transfer, long screw for open cuvette and short screw for closed cuvette. INDICATIONS Implant Direct Impression. In cases of severe disparallelism between implants or between implants and teeth, the impressions are taken using an open cuvette and long retention screw using the impression transfer for open cuvette. In cases of parallelism between implants or between implants and teeth, the impressions are taken using a closed cuvette and short retention screw using the impression transfer for closed cuvette. 6
ADVANTAGES In cases of pronounced disparallelism, taking the impression with an open cuvette allows you to perform a precise transfer of the implants to the working model. RECOMMENDATIONS You must follow the indicated procedure for the seating and fixation of the impression transfer in the implant. In the case of significant soft tissue thickness, we recommend taking a control X-ray of the seating of the transfer to the implant shoulder. ACCESSORIES AND CLINICAL MATERIAL Metal impression transfer for open cuvette or impression transfer for closed cuvette for BNT & TSH systems, according to the chosen technique. Phibo system 1.25 mm screwdriver. *Individual cuvette. *Impression material. *Impression material adhesive. LABORATORY BNT & TSH implant analogue Phibo 1.25 mm screwdriver *MATERIAL NOT SUPPPLIED BY Phibo INSTRUCTIONS FOR USE PROCEDURE IN THE CLINIC Remove the healing abutment. Select the technique for impression taking (open or closed cuvette) and, therefore, the corresponding impression transfer. Fit the 1.25 mm screwdriver into the retention screw, pass it through the transfer until it protrudes through the lower end. Fasten the transfer and screw unit to the implant head. To do this, place the unit on the implant, screwing it until you see that the base of the metal transfer has made contact with the implant head. Immediately after, loosen the retention screw and slightly turn the body of the impression taking clockwise or anti-clockwise. If the body does not turn, it is adjusted by the implant hexagon, if it turns you should combine gentle pressure in the occlusive-gingival direction with a turn until you see that the unit is seated between the hexagons. Finish screwing the retention screw and manually tighten (we recommend checking the fixation using a perioapical X-ray). Air-dry the transfer. Apply the impression material around the transfer. Insert the cuvette in the mouth with the rest of the impression material and wait until it sets. Open cuvette technique: Remove the fixation screw and drag the cuvette with the body of the transfer. Closed cuvette technique: Remove the cuvette directly once the impression material has set and remove the implant impression transfer. Replace the healing abutment. Send the following to the laboratory:. Impression cuvette.. Impression transfer with the corresponding screw.. Implant analogue.. Bite registration.. Antagonist model. 7
PROCEDURE IN THE LABORATORY Open cuvette technique: Position the implant analogue over the body of the open cuvette retained in the impression material and secure it with the retention screw. Closed cuvette technique: Secure the implant analogue to the closed cuvette with the screw. Insert the unit into the cuvette lining up the flat faces; apply light pressure until it clicks into place. Cast the zone corresponding to the soft tissue with soft resin and wait for it to set. Prepare the rest of the cuvette with plaster to obtain the final working model. Open cuvette technique: Once the plaster has hardened, remove the retention screw and separate the model. Closed cuvette technique: Once the plaster has hardened, separate the model from the cuvette and remove the metal impression transfer by loosening the retention screw. Prepare and mount the model in the semi-adjustable articulator. Use the registrations taken before surgery. Perform a study of: o Position of the implant (angulation and parallelism). o Spaces and dimensions available. o Height of the soft tissue for creation of the emergence profile. o Antagonist type. With the information obtained, choose the optimum abutments and necessary accessories for creating the prosthesis in the laboratory. CEMENTED FINAL RESTORATIONS DRILLABLE ABUTMENTS CHARACTERISTICS. Abutment machined with a smooth transition zone on the shoulder. The abutment fixation torque for the implant is 35 N cm.. Fixed prostheses cemented to drillable abutments are created using casting in metal of the base structure, modelled based on the titanium abutment itself. INDICATIONS. In general for single and multiple cemented restorations over the abutment.. To level the crown emergence height in relation to the adjacent natural teeth and the thickness of the soft tissue.. When it is necessary to adjust the height of the antagonist and parallelise the prosthesis insertion axis.. In single or multiple restorations where, due to the position of the implant, the retention screw entry hole in a screwed prosthesis compromises the aesthetic outcome of the restoration. CONTRAINDICATIONS. When the occlusal height from the implant is less than 4 mm. ADVANTAGES. Greater control of the aesthetic outcome of the prosthesis.. Resolves poor fit of the final crown to the abutment. DISADVANTAGES. Difficult to remove the excess cement. 8
