Edentulous sites in the posterior maxilla are often compromised by reduced bone volume, prohibiting the placement of 10-mm implants without sinus augmentation. The use of shorter implants minimizes the need for more extensive sinus floor elevation, thus reducing treatment duration and morbidity. Two implant designs are presented in combination with localized internal sinus floor elevation to restore the posterior maxilla. This simplified treatment modality can make implant rehabilitation of the atrophic posterior maxilla more accessible and more palatable to even the most reluctant patients and referring doctors.
上颌后部的无牙区常常因骨量减少而受到影响，若不进行上颌窦提升则无法植入10毫米的种植体。使用较短的种植体可将更广泛的上颌窦底提升需求降至最低，从而缩短治疗时间并降低发病率。本文介绍了两种种植体设计，并结合局部内部上颌窦底提升术来修复上颌后部。这种简化的治疗方式可使萎缩性上颌后部的种植修复对即使是最不情愿的患者和转诊医生来说也更容易接受且更合意。
