Purpose: The purpose of this retrospective study was to assess the effectiveness of ARP in damaged maxillary molar extraction sockets using porcine-derived block bone. Materials and Methods: A total of 28 damaged maxillary first and second molar extraction sockets underwent ARP with porcine-derived soft block bone. Vertical bone height changes were measured radiographically. The types of additional sinus augmentation procedures performed at the time of implant placement were also assessed. Results: ARP resulted in a vertical bone fill of 7.44 ± 2.08 mm. Implant placements were performed an average of 7.1 months after ARP. Among the 28 cases, lateral sinus floor elevation (LSFE) and transcrestal sinus floor elevation (TSFE) were performed in three and 18 cases, respectively. No additional sinus augmentation was required in seven cases. Conclusion: Within the limitations of this study, ARP appeared to reduce the need for the most invasive type of maxillary sinus floor elevation, namely LSFE, during implant placement.
