AICRG, Part V: Factors influencing implant stability at placement and their influence on survival of Ankylos implants.
PROBLEM Several factors influence primary stabilization of  dental implants  at placement surgery . These include implant design , bone quality , implant jaw location , and the use of a bone tap . PURPOSE This report evaluates clinical data gathered by the Ankylos Implant Clinical Research Group ( AICRG ) to assess ( 1 ) the influence of several variables on primary stability and ( 2 ) the potential for an Ankylos implant ( Friadent GmbH , Mannheim , Germany ) that is mobile at placement to integrate and survive for at least 3 years of clinical function . METHODS The Ankylos implant is a roughened grade -2 titanium screw .  A total of 1554 implants were placed in 478 patients . At both the time of placement and abutment connection , the implants were tested for evidence of clinical mobility by attempting to rotate or move the implant with an application of force . Survival was recorded from placement and up to 36 months following placement . RESULTS At placement , 2.8 % were found to be mobile . In the maxillary posterior quadrant , 6.3 % were clinical ly mobile . Implant mobility was frequent ( 12.2 % ) in jaw regions with poor- quality bone ( BQ-4 ) or with short implants ( 8 mm = 8.3 % mobile ) . Of the implants mobile at placement , 97.7 % were stable at uncovering . The 3-year postplacement survival of initially mobile implants was 84.1 % compared with 96.8 % for implants not mobile at placement ( chi2 test , P = .001 ) . CONCLUSIONS The Ankylos implant predictably promoted primary stability during surgical placement . Poor bone quality , short implants , and maxillary posterior jaw locations were all associated with a slightly higher rate of mobility at placement . Primary implant stability , while highly desirable , is not absolutely necessary for achieving osseointegration of
