abutments restoring BioHorizons implants with Laser-Lok esthetic abutments Laser-Lok esthetic abutments are used to create natural looking, cement-retained, single- or multiple-unit prostheses in the esthetic zone. The abutment margins are enhanced with the patented LaserLok surface technology which has been shown to establish a biologic seal of connective tissue fibers1 that protects and maintains the crestal bone and reduces pocket depth.2,3 The following technique describes a one abutment, one time approach which is ideal for establishing and maintaining the biologic seal. Place the prepped abutment in the mouth and check contours. Refine as needed. NOTE: Remove prepping particulate using an ultrasonic cleaner for ≥2 minutes and sterilize prior to placement. Torque the abutment screw to 30 Ncm. Place a cotton pellet in the screw access hole and fill with composite. Place the esthetic abutment at the time of surgery (one stage)4 or at implant uncovery (two-stage) shown here.5 Try-in an appropriate polycarbonate/shell crown and modify as needed using conventional crown and bridge techniques.6 Mark the areas which require modifications, height, margins, etc. Apply separator to the esthetic abutment, place acrylic inside the shell crown. Properly position over the abutment and perform a reline. Remove the abutment and place on a prepping handle using the abutment screw and an .050” hex driver. Prep as needed using a carbide/ coarse diamond bur of choice. Finish excess acrylic and polish. Adjust bite so it is out of occlusion and secure using temporary cement of choice.7 1.

An alternative approach is to take a digital impression (Cerec or similar) to design and fabricate a crown. 7. When performing cementation procedures, apply a minimal amount of cement to the inside margin surface of the restoration. Do not fill the restoration with cement.
