The UCLA Abutment is used for single or multi-unit screw or cement-retained restorations. Designed to fix implant angulation problems or in some cases problems of too much or too little depth, the design of the UCLA abutment enables the restoration to be attached directly to the implant fixture. Ideal in cases where there is limited interocclusal or interproximal distance or problems regarding implant angulation or soft tissue response.
Use manufacturer’s tooling to remove healing cap. For multiple units, start in the posterior and work toward anterior. Then, use manufacturer’s tooling to place transfer coping. Ensure components are fully engaged before tightening screw. Take an X-ray to verify proper seating of components. Next, ensure transfer coping does not hit tray. Use heavy body polyvinylsiloxane impression material. Record impression. Finally, when impression tray is removed, the transfer coping stays in the mouth. Remove transfer coping and replace healing cap. For multiple units, start in anterior and work toward posterior. Check fit of impression coping into impression. Send to lab.
Seat abutment. Torque screw into place per manufacturer’s recommendations. Next, use composite to fill over the implant screw. Cement restoration over implant with a resin-reinforced ionomer (i.e., RelyX, 3M ESPE).
