Restoring 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.
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.
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.
This 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.
由于后牙区萎缩性上颌骨骨量不足，为缺失牙植入种植体面临重大挑战。通常会考虑在外侧上颌窦提升术同期植入种植体，但这一决策通常基于现有骨量。本研究的目的是探讨使用自体骨环在萎缩性后牙区上颌骨同期植入种植体和上颌窦底提升的可行性。
一名58岁男性，上颌后牙缺失，左侧上颌窦明显气化，导致可用牙槽骨高度仅为2.6毫米。这限制了同期植入种植体的可能性。作为解决方案，采用自体骨环进行外侧上颌窦底提升，并同期植入种植体。
萎缩性后牙区上颌骨的解剖学限制给种植体植入带来重大挑战，通常需要分两阶段进行：第一阶段进行上颌窦底提升，第二阶段在骨移植成熟后植入种植体。然而，通过采用外侧上颌窦底提升并使用自体骨环同期植入种植体，可以显著缩短治疗时间。
本临床病例全面展示了在萎缩性上颌骨中采用单阶段方法植入种植体。它强调了在单个手术过程中同时解决骨增量和同期植入种植体问题从而显著缩短总体治疗时间的显著优势。这种方法不仅缩短了治疗过程，还通过减少多次干预的需求提高了患者的接受度。
