Implant restoration of the posterior maxilla poses significant challenges to the clinician. In an effort to increase the apical occlusal dimension of available bone for implant placement, a number of sinus augmentation approaches have been suggested. This paper describes a simplified technique for predictable sinus augmentation at the time of maxillary molar extraction.
A modified trephine and osteotome technique was utilized to implode the interradicular bone following maxillary molar extraction. Particulate material and a membrane were then placed to maximize regeneration of alveolar bone.
One hundred sixty-seven (1 67) implants were subsequently placed in regenerated bone following the above technique. One hundred thirty-seven (137) of these implants were restored and in function for up to 3 years at the time of statistical compilation, and 136 of the 137 implants were functioning successfully by the Albrekteson criteria for a cumulative success rate of 97.8%.
The technique presented for simultaneous sinus augmentation at the. time of molar extraction, followed by subsequent implant placement after maturation of regenerating tissues, demonstrates a high success rate for up to 3 years in function. Long-term studies may be useful in evaluating the continual efficacy of such an approach. J Periodontol 2002; 73:3944.
上颌后牙区的种植修复给临床医生带来了重大挑战。为了增加可用于种植体植入的牙槽骨的根尖向咬合面尺寸，人们提出了多种上颌窦提升方法。本文描述了一种在上颌磨牙拔除时进行可预测的上颌窦提升的简化技术。
采用改良的环钻和骨凿技术，在上颌磨牙拔除后使根间骨内陷。然后放置颗粒材料和屏障膜，以最大限度地促进牙槽骨再生。
按照上述技术，随后在再生骨中植入了167颗种植体。在进行统计汇编时，其中137颗种植体已完成修复并行使功能长达3年，根据阿尔布雷克特松标准，这137颗种植体中有136颗成功行使功能，累积成功率为97.8%。
本文介绍的在磨牙拔除时同时进行上颌窦提升，随后在再生组织成熟后植入种植体的技术，在长达3年的功能行使中显示出较高的成功率。长期研究可能有助于评估这种方法的持续有效性。《牙周病学杂志》2002年；73:39 - 44。
