Autogenous bone ring augmentation and simultaneous implant placement in the atrophic posterior maxilla: A case report.

introduction and importanceRestoring lost teeth in the posterior atrophic maxilla presents a significant challenge due to insufficient bone volume for implant placement. Simultaneous implant placement during lateral sinus lift is often considered, but the decision is typically based on the amount of existing bone. The aim of this study was to investigate the feasibility of simultaneous implant placement and maxillary sinus floor augmentation in the atrophic posterior maxilla using autogenous bone ring. CASE PRESENTATION: A 58-year-old man presented with teeth loss in the posterior upper jaw and significant sinus pneumatization on the left side, resulting in only 2.6 mm of available alveolar bone height. This limited the possibility of simultaneous implant placement. As a solution, lateral maxillary sinus floor augmentation using an autogenous bone ring was performed, along with the insertion of the implant. CLINICAL DISCUSSION: Anatomical limitations in the atrophic posterior maxilla present significant challenges for implant placement, often necessitating a two-stage approach: the first stage involves maxillary sinus floor augmentation, followed by implant placement in the second stage after bone graft maturation. However, by employing lateral sinus floor elevation combined with immediate implant placement using autogenous bone ring, treatment time can be significantly shortened.

conclusionThis clinical case provides a comprehensive demonstration of implant insertion in an atrophic maxilla utilizing a single-stage approach. It underscores the significant advantage of reducing overall treatment time by concurrently addressing both bone augmentation and immediate implant placement within a single procedural session. This approach not only shortens the treatment process but also enhances patient acceptance by minimizing the need for multiple interventions.
