2 INTRO The dental impressions arrive in the laboratory already disinfected and together with the work requirements, medical office, data and references about the pacient or an identification code. The operator responsible for acceptance checks the completeness of the data, records the work and completes the technical sheet The operator verifies the material with which the impressions were taken and establishes the type of material to be used to develop the models. Class IV gypsum is recommended Mix the vaccum-sealed gypsum, in accordance with the proportions and time-table indicated by the manufacturer An electric shaker could be helpful to cast the impression The model plater socket must be realized on the adequate VERTYSYSTEM s systematic Split Cast. As an alternative, VERTYS ARTIC LINK M base may be used. Before disconnecting the model from the impression, wait for the hardening time indicated by the manufacturer A. MODEL PREPARATION The developped model is desengaged, trimmed and squared The model should have a minimum heel of 15 mm of height and a 5 mm lateral border Place the models in articulator through the VERTYS ARTIC LINK F bases Construction of the skeleton as usual Perform tooth assembly and complete the wax modeling of the saddles With a wax casting plug,diameter of 3/5 mm, connect the saddle of the skeleton (always in the front).fix the ends of the plugs with the wax. If possible always place the wax plug on the metal part, in case of a upper model on the palatine plaque, in the lower following the lingual bar. This allows, once the skeleton is finished, and cut with a disk separating the two ends, to easily remove the resin plug. B. FIRST TEMPLATE-MOLD REALIZATION WITH VERTYS ORANGE PLUS Prepare about 20 g (10 g A + 10 g B) of HIGH SECURITY FLUID silicone and brush with a small brush all the teeth, including the occlusal part. We recommend also covering the gingival collars in waxand! - Apply the remaining material with a spatula - Let it harden for about 8/10 min. - This material allows us to obtain a precision of the gingival modeling and an extraordinary tooth stability! Prepare about 60 g (30 g A + 30 g B) of VERTYS ORANGE PLUS silicone Knead for 20 sec.and adapt the silicone on the skeleton covering it completely Be careful to cover both wax parts and metal parts (hooks and plate/bar) If the plaster model presents, above all vestibularly, holes in undercuts, eliminate them with VERTYS EASY PUTTY silicone Insert the model, with VERTYS ORANGE PLUS mask, in the APOLIX heat press - without water - at temperature 0 C / zero degrees celsius (with thermostat deactivated) - at the pressure of at least 2 atmospheres, maximum 6 atmospheres - let the silicone harden for 7 minutes Once hardened, put the model on the Split Cast of the FURBO ALU BIG / SMALL muffle Insert the steel spacer needed in the 3 guide rods of the muffle Now insert the muffle cover on the 3 guide rods and check that there are not interferences and contacts In particular, make sure that there is a space of at least 1 cm between the template-mold and the cover of the muffle Once hardening occured, apply the VERTYS ORANGE SPECIAL LUBE insulation spray on the silicone VERTYS EASY PUTTY, with which the sub-squares have been eliminated C. BOXAGGIO WITH VERTYS EASY PUTTY SILICONE Knead 160 g (80 g A + 80 g B) of VERTYS EASY PUTTY for at least 20 sec. Adapt about half of the mixture on the inside of the FURBO ALU BIG / SMALL muffle cover and use the remaining VERTYS EASY PUTTY for the boxing of the second stamp-stain, containing the model and the product Insert the muffle cover into the appropriate guide rods and compress until the cover is fitted with the spacers on the 3 gide rods Immediately block the muffle cover with the appropriate stop nuts Tighten with the VERTYS VERTYS DYNAMO BLOCK dynamometric nut First compress the silicone leaked from the top slot of the muffle, and immediately after, the silicone leaked out at the base of the model You will obtain the adaptation of the silicone on the second mask and a perfect sealing This step must be carried out with the utmost care in order to prevent the leakage of the resin during the injection phase To check the perfect closure of the FURBO ALU BIG/SMALL, the spacers must not rotate on the guide rods Wait for the hardening of the VERTYS EASY PUTTY for about 7 minutes After hardening, unscrew the nuts, remove the muffle cover from the 3 guide rods, and extract the model from the first silicone mask 2/5

3 D. PREPARATION OF THE INLET AND OUTLET HOLES IN THE SILICONE DURING THE INJECTION PHASE Take the muffle cover with the second mold template inserted and, with the supplied reamers, drill two holes in the silicone in correspondence of the two ends of the molding, starting from the inside of the template mold, until it comes out of the muffle cover In this way the inlet and outlet channels for the acrylic resin injection will be created Entry hole with large reamer # Output hole with small reamer # Using the correct reamer ensures that the hole diameter exactly matches the diameter of the syringe tip that will be used for resin injection The exit hole must always be done with the small reamer Using a scalpel, perform a flaring on the silicone in correspondence with both holes This will create two wells that will serve to contain the resin reserve when injected E. WASHING AND DEGREASING THE PLASTER MODEL ANDACRYLIC THEET Carefully wash and degrease the model and any hooks with steam or hot water Immerse the model in water at a temperature of C Leave it soak for 10 minutes to allow saturation In this way it is avoided that the plaster can absorb the resin monomer when it is injected Open the cover of the HELP # basket and insert the teeth into the specially created seats, thus avoiding to confuse them when the washing is finished. Screw the HELP lid and proceed with the degreasing by steaming or boiling in hot water Dry with compressed air F. PREPARATION OF THE FURBO ALU BIG / SMALL MUFFLE FOR THE RESIN INJECTION Create mechanical/chemical retentions, channel shapped, to acrylic teeth Reinsert the teeth into their seats, inside the second silicone mold template Remove the model from the lukewarm water and insulate it with a very thin layer of VERTYS LUBE alginic insulation Let the model dry Opacify the retentions with the VERTYS OPAK PINK Insert the Skelethon in the first silicone mold mask. The prepared model, must now be inserted into the second silicone mold mask and brought together with VERTYS SPLIT CAST of the FURBO ALU BIG / SMALL muffle. Make sure that the necessary spacers are inserted in the 3 guide rods Insert the appropriate muffle lid in the appropriate guide rods and slide it until it contacts the steel spacers Close it with the fixing muffle bolts. Tighten with the VERTYS VERTYS DYNAMO BLOCK dynamometric nut G. PREPARATION OF THE RESIN FOR VERTYS PROTHESIS EXCEL / PLUS INJECTION Weigh the necessary amount of powder and liquid of the acrylic resin for orthodontics, in the proportions indicated in the instruction fot the use of VER- TYS PROTHESIS EXCEL / PLUS Approximately 10 g of powder and 6 g of liquid are required for a medium-sized partial denture Pour the liquid in the MIXING CUP Then pour the powder and mix it for 10 seconds. let it rest for another seconds Pour the resin into a one time use syringe,versare ora la resina in una siringa monouso da 30 cc, having the foresight to close the exit hole with a finger Insert the plunger and turn the syringe upside down Push the plunger until any air bubbles will escape Maintain the pressure on the plunger until you obtain a small resin leakage from the tip of the syringe. The resin is ready when it assume a filamentous consistency. The consistency time and injection time may vary, depending even significantly, based on the environmental conditions H. INJECTION PROCEDURE FOR THE ACRYLIC RESIN With one hand hold the muffle inclined at 45 so that the outlet hole is lower than the inlet hole By doing so you, air bubbles will be avoided during the injection phase Insert now the syringe tip in the lower inlet hole and slowly and continuously push the plunger until there is a leakage of the resin from the top hole (the injection time is usually of 1/1,30 min.) Always maintaining the syringe plunger under pressure, straighten the muffle, place it on the workbench and continuous the injection and pressure phase It is important not to remove all the resin, but leave the groove previously created full Slowly remove the syringe but always maintain the pressure Immediately also fill the second reserve groove The injection phase is now completed, the injection phase is now completed and in correspondence of the inlet and outlet grooves, there are now visible the two reserve buttons The muffle can be placed into the heat press once the resin of the button becomes slightly elastic and it doesn t stick to the fingers 3/5

4 I. ACRYLIC RESIN POLYMERIZATION Insert the FURBO ALU BIG/SMALL muffle into the APOLIX heat press by paying attention to: 1. The water, inside the heat press, must be at room temperature 2. The water lever must not be over the muffle cover ( it is very important that the two inlet and outlet holes of the resin are not covered) 3. The pressure must not be over 2 atmospheres For the temperature and the polymerization times please follow the instruction for the resin VERTYS PROTHESIS EXCEL / PLUS resin Once the polymerization has been completed, remove the muffler from the APOLIX heat press (or pressure cooker) Remove the two resin buttons, in correspondence of the grooves, by breaking them with the help of plaster knife or by cutting them with a diamond disc Open the muffle and remove the model and artefact from the silicone template mask Remove the two imput and output plugs with a cutter Cut the resin connection plug J. CONTROL IN THE ARTICULATOR Insert the model together with the bite in the AR.GO articulator for a check ( or in the articulator that is usually used) Proceed with the finishing touch and polishing SILICONE WEIGHTS MATERIALS First mask mold: 60g VERTYS ORANGE PLUS First mask mold: VERTYS ORANGE PLUS Second mask mold: Insulators - VERTYS LUBE Boxaggio: 160g VERTYS EASY PUTTY Optional: 20g HIGH SECURITY FLUID Boxaggio: VERTYS EASY PUTTY (70 Shore) Resin: VERTYS PROTHESIS EXCEL / PLUS PROCESSING TIME First mask mold: minimum manipulation 20 sec.
