PROTOCOL FOR USE

WARNING !

Ensure that the Multi-Unit pre-assembled holder IS CORRECTLY placed on the Multi-Unit abutment before placing it in the mouth.

If mouth opening is narrow, remove the pre-assembled holder supplied with the Multi-Unit abutment and use the short pre-assembled holder (Ref. MUWS)

•

STRAIGHT MULTI-UNIT ABUTMENT

 Screw the straight Multi-Unit abutment into the im- plant using the Multi-Unit abutment pre-assembled holder. Then, remove the pre-assembled holder. Tighten the Multi-Unit abutment to 25 N.cm with the prosthetic torque wrench (Ref. INCCD) and the Multi-Unit wrench (Ref. MUW100) or the TORQ CONTROL®

and the Multi-Unit mandrel (Ref. MUM100 or MUM100L)

ANGLED MULTI-UNIT ABUTMENT

 Insert the angled Multi-Unit abutment in the correct orientation (for indexed components, select the appro- priate position). Insert the Multi-Unit Black Tite® _M1.6 fixation screw dedicated to Multi-Unit (Ref. OPMU160) using the long hexagonal wrench

Tighten the screw to 25 N.cm using either the torque wrench (Ref. INCCD) and the long hexagonal wrench, or the TORQ CONTROL® _{and the hexagonal}

tightening mandrel. Then, remove the holder.

•

 Place a Multi-Unit Pick-up Ø 4.0 mm transfer coping (Ref. MUT100) on each Multi-Unit abutment and secure it by inserting a short or long coping screw or Multi-Unit Pop- in transfer (Ref. MUT200).and hand tightening (using mod- erate force < 10 N.cm)

 Use a closed impression tray for a Pop-In transfer impression (Pop-In technical) or an open impression tray (Pick-up technical).

 At this stage, two options are available: put the Multi- Unit protective caps (Ref. MUCAP) back into place and hand tighten them (using moderate force), or do a provisional prosthesis from the appropriate coping(s) (Cf. Tempo- rary prosthesis ).

•

 Screw the Multi-Unit analog (Ref. MUA100) in each transfer

 Create the master model..

Connect temporary copings

 Connect the appropriate temporary copings: Multi- Unit titanium ones (Ref. MUC100) or Multi-Unit PEEK ones (Ref. MUC200) on Multi-Unit abutments.

 Tighten the temporary caps on the straight Multi-Unit abutments with the titanium fixing screw M1.4 short blue (Ref. MU141). Moderate manual tightening (<10 N.cm) with hexagonal wrench.

 Remove and adjust the height of the temporary cap if necessary.

Fabricate the provisional

 Fill a plastic mould or a template with acrylic resin. In the case of a template, holes must be made to allow the long pick-up transfer coping screws to pass through.  Place the mould or perforated resin template over the adjusted temporary copings. (Let the laboratory screws (Ref. MUT101 or MUT102) dedicated to the Multi-Unit abut- ments)

 Allow the resin to harden or polymerize.

Remove the provisional and make final adjust- ments

 Remove the fixation screws.

 Remove the resin template and temporary restora- tion.

 Separate the temporary coping from the template.  After final adjustments have been made, the provi- sional is polished.

 Protect each connecting element with Multi-Unit pro- tection analogs (Ref. MUA200)

In the mouth

Connect the provisional

 Reposition the temporary prosthesis with the M1.4 Multi–Unit titanium fixing screw supplied with the tem- porary cap using a hexagonal wrench.

 A retroalveolar X-ray is most useful to confirm proper implant-abutment connection.

Tighten to 15 N.cm using the dynamometric prosthesis wrench (Ref. INCCD) or using the TORQ CONTROL®_.

WARNING !

Unless immediate loading is performed, the provisional should be placed out of occlusion so as not to compro- mise device integrity.

Login screeds 100% castable

 Connect the Multi-Unit castable copings (Ref. MUC300) to the Multi-Unit abutments analogs (Ref. MUA100) in the master model using the Multi-Unit titanium M1.4 short blue fixation screws (ref. MU141).

NOTE: before adding resin, insert the laboratory screw (Ref. MUT101 or MUT102) or the corresponding Multi-Unit long pick-up transfer coping screws (hand tighten to a torque <10 N.cm). Use the long hexagonal wrench to prevent intrusion of the resin into the screw holes.

 Adjust the castable caps to recreate the custom frame- work shape (or castable bar) by drilling and/or adding castable resin and connecting each cap.

Fabricate the final restoration using the pouring technique

 Strictly follow the material manufacturer’s instruc- tions for pouring.

NOTE: Multi-Unit protection analogs (Ref. MUA200) are available to protect the Multi-Unit connection system during fabrication of the final restoration.

Validate the poured component

 Return the poured component to the appropriate po- sition in the master model, and secure it using a Multi- Unit titanium M1.4 fixation screw (torque <10 N.cm) to assess proper seating.

In the mouth

Place the final restoration

 Place the final restoration onto the Multi-Unit abut- ments and insert the Multi-Unit Black Tite® _{M1.4 fixation} screws (Ref. MU140) .

Tighten to 15 N.cm using the dynamometric prosthesis wrench (Ref. INCCD) or using TORQ CONTROL®_.

BRIDGE: after protecting the head of the screw using a removable filling product, fill the access holes using an acrylic material and then finalise the occlusal adjust- ment.

BAR: carry out any occlusal and tissue adjustments to the overall prosthesis before final tightening.

Inform the patient of the directions for use and care.

Specific instructions for these caps are available on ifu.anthogyr.com. Please refer to these instructions before mak- ing the cast. Code IFU: MUC400

In the laboratory

Connection of CoCr caps

 Connect the CoCr Multi-Unit caps (Ref. MUC400) to the Multi-Unit abutments analogs (Ref. MUA100) with the M1.4 short blue fixation screws (ref. MU141).

NOTE: Before adding resin, insert the laboratory screws or the corresponding long transfer coping screws Multi- Unit Pick-up (moderate manual tightening to <10 N.cm) with a hexagonal wrench.

 Adjust the castable caps to recreate the custom frame- work shape (or castable bar) by drilling and/or adding casta- ble resin and connecting each cap.

Creating final prosthesis using a casting technique

 Create the cast according to the recommendations of the material’s manufacturer using an overcast CoCr with a melt- ing temperature of 1338°C.

The selected alloy must respect the following standards: ASTM F1537, ASTM F795, ISO 5832-12 and ISO 5832-4. The cast alloy must cover the entire CoCr cap, otherwise the porcelain may not bond properly and may crack.

The thickness of the resin and the castable cap must be over 0.5mm before casting and must be resized to 0.3mm after casting.

NOTE: The Multi-Unit protective analogs (Ref. MUA200)are available to protect the Multi-Unit connector while the prosthesis is being produced.

Verification of the cast structure

 Replace the cast structure over the master cast using the M1.4 short blue fixation screws (ref. MU141).(moderate manual tightening <10 N.cm) in order to check the fit.

In the mouth

Application of the prosthesis

 Position the prosthetic structure over the Multi-Unit abutments. Tighten the M1.4 Multi-Unit Black Tite® _fixing

screws (Ref. MU140).

Tighten to 15 N.cm using the dynamometric prosthesis wrench (Ref. INCCD) or using TORQ CONTROL®_.

BRIDGE: after protecting the head of the screw using a removable filling product, fill the access holes using an acrylic material and then finalise the occlusal adjustment. BAR: carry out any occlusal and tissue adjustments to the overall prosthesis before final tightening.

•

Inform the patient of the directions for use and care.Re- placing the screws in place with new ones every time the prosthesis is unscrewed is recommended.
