Background: Immediate implant placement after tooth extraction is a predictable solution in various clinical situations. The purpose of this study was to evaluate the predictability of a treatment, including the placement of implants, using a modified insertion technique at the time of maxillary molar extraction.

Materials: Sixty-eight patients with a total of 68 teeth scheduled for tooth extraction and immediate implant placement into fresh sockets were included in the study. Implants were positioned just after teeth removal and, in case of necessity, a regenerative therapy was performed at the same time. After a 3-month period of healing, implants were restored with single crown fixed prostheses.

Results: All implants restored with single crowns were monitored for 36 months; only, 3 implants failed with a cumulative survival rate of 97.96%.

Conclusion: The combination of atraumatic extraction of maxillary molars, sufficient residual inter-radicular bone, and the use of appropriate regenerative material at the time of implant insertion, represents a predictable long-term treatment.
