Evidence analysis shows that the present knowledge about biologic width around implants is mainly derived from animal studies and that clinical controlled human studies are insufficient
PURPOSE The concept of biologic width forms a basis for successful peri-implant soft tissue integration around titanium implants .
Therefore , the objectives of this review are to determine and critically evaluate the present knowledge about biologic width around implants and to establish future research trends .
Osseointegrated implants for single-tooth replacement: progress report from a multicenter prospective study after 3 years.
After 3 years , 82 of the original 92 patients remain in this prospect i ve multicenter study of single-tooth restorations supported by Brånemark implants . Since the 1-year follow-up , 6 more patients have been lost , but no additional implants have failed in those patients examined at the 3-year follow-up visit . After 1 year of function , 97.2 % of the implants survived in 88 patients , and between the 1- and 3-year follow-up , 100 % survived in 82 patients , giving a 3-year cumulative success rate of 97.2 % . No changes were observed in the status of gingivitis , pocket depth , periodontal pocket bleeding index , and tooth and implant mobility from those reported after 1 year . Marginal bone resorption remained at a low level -- less than 0.1 mm annually during the second and third years . Abutment screw loosening continued , but at a significantly reduced rate from that reported after 1 year . When used , gold rather than titanium abutment screws remained secure
