In the clinical practice of dental implants, the implant-related surgery in areas with proximity to a periapical lesion of adjacent teeth was relatively particular but not uncommon. Chronic apical periodontitis of adjacent teeth could become a potential source of infection in bone augmentation surgery and cause early surgery failure/or extend to the apical area of the implant and cause retrograde peri-implantitis. Unlike the traditional treatment modality, a novel digital treatment modality involves the performance of implant-related surgery in conjunction with endodontic microsurgery of the adjacent tooth during one process to control the potential risk originating from apical periodontitis, completely remo-ving the infection from the apex of adjacent teeth and establishing sufficient apical sealing. This combined surgery aimed to eliminate the potential source of infection of adjacent teeth during implant-related surgery. Meanwhile, the autologous bone retained in the apical surgery could avoid a second operating area for bone harvesting in bone augmentation surgery, significantly improving the efficiency of surgery and thus further reducing patient trauma and saving medical costs. This article discussed the application basis and clinical indications of this novel combined treatment strategy.

Key words: dental implant, guided bone regeneration, endodontic microsurgery, guided tissue regeneration, retrograde peri-implantitis
