Based on the diagnostic wax-up, a radio- graphic stent was fabricated and used to per- form a cone beam computed tomography scan for implant placement planning. A surgical guide based on the milled wax-up was used to place 2 4.1 × 10.0 mm implants (Tapered Screw-Vent Implants, Zimmer Biomet, Warsaw, Ind., U.S.) in the position of teeth #3.4 and 4.5 and two 4.75 × 10.0 mm Tapered Screw-Vent implants in the positions of teeth #3.6 and 4.7. Three months later, a second-stage surgery was performed to uncover the implants and healing abutments were placed for a period of 2 weeks. At the preparation appointment, teeth #1.7 through 2.4 and teeth #3.3 and 4.4 were pre- pared for full-coverage anterior lithium disilicate 44 Volume 3 | Issue 4/2017 Journal of Oral Science & Rehabilitation
