For the treatment of impacted maxillary canines, traction associated with a complete orthodontic treatment is the first choice in young patients. However, in adults, this treatment has a worse prognosis. The surgical extraction of the impacted tooth can result in a series of complications and a compromised alveolar bone integrity, which may lead to the requirement of a bone regeneration/grafting procedure to replace the canine with a dental implant. These case reports aimed to describe an alternative treatment procedure to the surgical extraction of impacted maxillary canines in adults. Following clinical and computerized tomography-scan (CT-Scan) examination, the possibility of maintaining the impacted canine in its position and replacing the temporary canine present in its place with a dental implant was planned. A short dental implant with an immediate provisional crown was placed, without contacting the impacted canine. At 3 months follow-up, a definitive metal-ceramic restoration was placed. Follow-up visits were performed periodically. The implant site showed a physiological soft tissue color and firmness, no marginal bone loss, no infection or inflammation, and an adequate aesthetic result in all follow-up visits. These results suggest that the treatment carried out is a valid option to rehabilitate with an osseointegrated short implant area where a canine is included, as long as there is a sufficient amount of the remaining bone.
对于上颌阻生尖牙的治疗，在年轻患者中，与完整正畸治疗相关的牵引是首选方法。然而，在成人中，这种治疗的预后较差。拔除阻生牙的手术可能会导致一系列并发症以及牙槽骨完整性受损，这可能需要进行骨再生/植骨手术，以便用牙种植体替代尖牙。这些病例报告旨在描述一种针对成人上颌阻生尖牙拔除手术的替代治疗方法。经过临床和计算机断层扫描（CT扫描）检查后，计划保留阻生尖牙在其位置，并使用牙种植体替代其位置上的临时尖牙。植入了一枚带有即刻临时冠的短牙种植体，使其不与阻生尖牙接触。在3个月的随访中，放置了最终的金属烤瓷修复体。定期进行随访。在所有随访中，种植部位显示出正常的软组织颜色和质地，无边缘骨丢失，无感染或炎症，并且美学效果良好。这些结果表明，只要剩余骨量充足，所进行的治疗是一种用骨整合短种植体修复包含尖牙区域的有效选择。
