The extraction of a tooth with root resorption can be a complicated procedure and can result in the removal of a significant amount of alveolar bone. In the anterior maxilla, esthetic rehabilitation of damaged sites with implant-supported crown could require multiple surgeries. Patients often ask for an alternative, and minimally invasive treatments are generally preferred. In this paper, a clinical case of implant-supported crown in a site affected by root resorption is described. Immediate implant was placed leaving some root fragments in the osteotomy site, thus avoiding invasive extractive surgeries. A minimally invasive flapless technique with a computer-guided implant placement procedure was used. After ?8 years, clinical and radiologic data were stable, gingival tissues around the implant appeared healthy, no dark translucency appeared through marginal gingiva around the implant, and there was no pathologic probing pocket depth ?or bleeding on probing. In the presence of root resorption and ankylosis, computer-guided surgery could be helpful to prepare a precise implant site through various tissues, such as partially resorbed root remnants.
