Zero bone loss concepts. Surgical and Prosthetic Summary
Mucosal tissue thickness was shown to be the factor having impact on 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, finished implant restoration with occlusal opening is cemented on titanium base in laboratory and restoration is attached to the implant by an abutment screw. Zirconium as a material is considered the best for peri-implant soft tissues. However, it’s evident that it must be treated in special manner and polished.
- To know the influence of vertical soft tissue thickness on crestal bone stability and be able to diagnose this condition
- To understand how platform switching correlates with vertical soft tissue thickness and depth of implant placement
- To learn how control cement excess during delivery of cement-retained implant restorations.

Dr. Tomas Linkevicius
Tomas Linkevičius serves as Professor in Institute of Odontology, Vilnius University in Lithuania. Also he works as Visiting Professor in Ghent University, Belgium. He received a dental degree in Kaunas Medical University in 2000. In 2004 he completed the post-graduate studies in prosthodontics in Vilnius University. In 2009 he finished his PhD doctoral dissertation and defended it in Riga Stradins University in Latvia. Tomas Linkevicius is an author of many publications in international peer-reviewed journals and focuses his research on soft tissues and cementation of implant restorations. Professor Linkevicius has developed “Zero bone loss concepts”, a scientifically backed clinical protocol, which shows how to archive and maintain crestal bone stability around implants. He also lectures internationally and is an active member of European Academy of Osseointegration (EAO) and Academy of Osseointegration (AO). Tomas Linkevicius holds a specialist prosthodontics and implant dentistry practice and a private dental research facility.
