Zero Bone Loss Concepts: An Evidence-Based Clinical Guide for the Development and Maintenance of Bone Stability Around Implants
Mucosal tissue thickness can have a significant impact on crestal bone stability, so it is suggested that thin tissues be thickened during implant placement in order to reduce bone resorption. The solutions put forward depend on the crestal bone height and include (1) bone reduction to passively augment soft tissue proportion, (2) subcrestal placement to achieve greater soft tissue contact, or (3) a “tent” technique that involves covering the abutment with the flap to facilitate soft tissue growth. If bone height is not sufficient, vertical augmentation of the soft tissue is recommended. Further, it is important to preserve bone levels after prosthetic treatment. Recent research has proven that the deeper the position of the margin, the greater the amount of residual cement left undetected. To avoid this, the implant restoration (with an occlusal opening) is cemented onto a titanium base in the laboratory, and the restoration is attached to the implant using an abutment screw.
