The purpose of this study was to provide feasibility of a new technique of sinus graft: outfracture osteotomy sinus graft.
The author modified the window opening method from the original trapdoor technique to an outfracturing and readaptation technique. It provides a few advantages in dental implant treatment of atrophic maxillary posterior edentulous alveolar ridges: 1) in combined cases of height and width problems; 2) in cases with anatomic problems such as sinus septum, thick lateral sinus wall, and intrabony bleedings; 3) possible use of the outfractured bony segment as a covering membrane.
The follow-up of 34 patients (40 cases; 6 bilateral cases) revealed good results without a case of graft failure and showed excellent survival and function of the dental implants.
The sinus graft technique was modified as the author outfractured and readapted the bony lateral window, with several advantages as mentioned above. This new outfracture osteotomy sinus graft technique has excellent results as an alternative to the original trapdoor technique.
本研究的目的是提供一种新的鼻窦移植技术——外折骨切开鼻窦移植术的可行性。
作者将开窗方法从原来的活板门技术改进为外折和重新适配技术。该技术在萎缩性上颌后牙无牙牙槽嵴的牙种植治疗中具有一些优势：1）在高度和宽度问题并存的病例中；2）在存在解剖问题的病例中，如鼻窦隔、鼻窦侧壁增厚和骨内出血；3）有可能将外折的骨段用作覆盖膜。
对34例患者（40例；6例双侧病例）的随访显示效果良好，无移植失败病例，牙种植体的存活率和功能良好。
作者对外侧骨窗进行外折和重新适配，对鼻窦移植技术进行了改进，具有上述多种优势。这种新的外折骨切开鼻窦移植技术作为原始活板门技术的替代方法，效果极佳。
