A 5 mm healing cuff is placed with Cetacaine and antibiotic ointment nearly 3 months postop. The implant remains subgingival with the healing abutment 4 months postop. With Cetacaine and 2 gingival retraction cords, the implant margin is barely exposed. Large and deep gingivectomy is performed with Waterlase without too much pain. The gingival cuff is slightly erythematous and hemorrhagic on cementation (partially due to suboptimal oral hygiene, Fig.7). The margin is deep. Tatum implants are contraindicated when the gingiva is thick (Fig.8).
