Techniques to Preserve Keratinized Peri-Implant Mucosa in CT-Guided Oral Implant Surgery

Abstract

Guided implant dentistry using computed tomographic (CT) scans, virtual planning software and mucosa-supported surgical templates is an upcoming technology with the potential for more predictable and less invasive implant placement. While generally associated with a flapless approach, soft tissue punching and removal may not be indicated if available width of keratinized mucosa is limited prior to implant surgery. Two techniques to preserve keratinized peri-implant mucosa (Punch Reposition Technique and Topical Flap Technique) are presented and indications outlined. Appreciation of soft tissue conditions as well as functional and esthetic consequences of mucosal deficiencies (mucosal-driven approach) is recommended to supplement bone- and prosthetic-driven considerations in guided oral implant placement (Trinity Approach).
