Is Keratinized Tissue Needed Around Implants?

Traditionally, most clinicians have focused on peri-implant bone as a prerequisite for implant success. However, it is now recognized that peri-implant mucosal tissue is an important key for the functional stability and esthetics of implant restorations. A variety of risk factors can predispose to soft tissue deficiencies such as mucosal recession or defective contours. Correction of peri-implant recession defects is more challenging than around teeth. Therefore, effective risk assessment should be employed in order to avoid the occurrence of peri-implant mucosal deficiencies.




Learning Objectives:
• Understand risk assessment for prevention of peri-implant defective mucosa
• Understand rationale and technique of “vestibular incision subperiosteal tunnel access” (VISTA) for prevention and correction of soft tissue esthetic and functional defects around implants
• Understand application of autogenous tissue, allograft, xenograft and growth factors for soft tissue augmentation
