The choice of implant length in relation to the available bone quality and quantity and biting force is a critical factor in the success of implants and longevity of the prosthesis. Long implants have always been considered more desirable in this respect but in patients with advanced alveolar bone resorption, their placement is problematic due to the anatomic boundaries. This holds more true in relation to the posterior maxilla wherein the residual crestal bone height is usually compromised due to pneumatizing sinus floor. In this study, we have incorporated the use of short implants in conjunction with indirect sinus lift for cases with severely resorbed posterior maxillary edentulous regions to avoid direct sinus lift surgery and increase patient comfort. A 63-year-old patient had tooth 16 missing and wanted implant rehabilitation. The residual alveolar bone height was 3 mm. Short implant placement after indirect sinus lift was achieved with good primary stability. Prosthetic loading was performed after six months. One year follow-up showed no complaints or discomfort. In cases where the residual alveolar bone height of the edentulous space in the posterior maxilla was less than 4 mm, the use of indirect sinus lift with placement of short implants (height < 6 mm) proved to be advantageous over a direct sinus lift procedure with delayed placement of standard-length implants. This technique was less time-consuming, less surgically morbid, and more economical. The patient compliance was superior and no complaints were faced in a one-year follow-up period.
根据可用骨质量和数量以及咬合力来选择种植体长度是种植体成功及修复体长期使用的关键因素。在这方面，长种植体一直被认为更理想，但在牙槽骨严重吸收的患者中，由于解剖边界的限制，种植体的植入存在问题。这在与上颌后牙区相关的情况中更为明显，其中由于上颌窦底气化，剩余牙槽嵴顶骨高度通常会受到影响。在本研究中，对于上颌后牙区严重吸收的无牙区域病例，我们采用了短种植体结合间接上颌窦提升术，以避免直接上颌窦提升手术并提高患者舒适度。一名63岁患者缺失16号牙，希望进行种植修复。剩余牙槽骨高度为3毫米。间接上颌窦提升术后植入短种植体，获得了良好的初期稳定性。六个月后进行修复体加载。一年随访显示无任何不适主诉。在上颌后牙区无牙间隙剩余牙槽骨高度小于4毫米的病例中，使用间接上颌窦提升术并植入短种植体（高度<6毫米）被证明比直接上颌窦提升术并延迟植入标准长度种植体更具优势。该技术耗时更少、手术创伤更小且更经济。患者依从性更好，在一年随访期内未出现任何不适主诉。
