Immediate implantation has some disadvantages such as incongruence with the extraction socket which leads to the lack of primary stability and need for guided tissue regeneration to prevent soft tissue migration to the space between tooth and implant. Custom-made anatomical dental implants (CAI) were introduced to avoid such disadvantages. However, there are no studies which evaluates the need for grafting and its effects on stability and survival. 56 CAI were included in this study. The need for bone grafting after implant placement was evaluated. Marginal bone loss was measured from the periapical radiographs which were taken on the first and 90th day of implant placement. Furthermore, Periotest values were measured to evaluate the implant stability with Periotest M® device on the first (PTV0) and 90th day (PTV3) of implant placement. 20 (52.6%) of nongrafted and 9 (50%) of grafted implants were lost. There was no statistically significant difference between the survival of grafted and nongrafted implants (p=0.834). PTV0, PTV3, mesial and distal bone loss values were not statistically significant in both grafted and nongrafted implants (p>0.05). In conclusion, even with CAIs, bone grafting may be required. This study shows that grafting has no negative/positive effect on survival and stability of CAIs.
