Zero Bone Loss Concepts by Prof. Tomas Linkevičius

Mucosal tissue thickness was shown to be an important factor on the impact of crestal bone stability. Even platform switching of the implant-abutment connection does not reduce crestal bone loss, if soft tissues at the implant placement are thin. It is suggested that thin tissues might be thickened during implant placement, thus reducing bone resorption. If bone height is not sufficient, vertical augmentation of the soft tissue is recommended with different materials – autograft, a xenograft or a dermis-derived allograft.

Further, it is important to preserve bone levels after prosthetic treatment. Recent research has proved that the deeper the position of the margin, the greater amount of residual cement is left undetected. The relation between position of cement excess in the peri-implant sulcus, periodontal status of the patient and severity of peri- implant disease is explained. To avoid cement excess, a finished implant restoration with an occlusal opening is cemented on a titanium base in laboratory and the restoration is attached to the implant by an abutment screw. Zirconium is considered the best material available for peri-implant soft tissues. However, it’s evident that it must be treated in a special manner and polished.

Influence of vertical soft tissues on crestal bone stability. Does platform switch save the bone? Influence of implant placement depth on crestal bone stability. What is the importance of implant-abutment connection stability? Bone remineralization and corticalisation processes in thick tissues. What is the role of bone in “Zero bone loss concepts”?

Four novel methods to increase vertical soft tissue thickness

  1. Subcrestal implant placement
  2. Flattening of the alveolar bone
  3. “Tent pole” technique
