The aim of this study is to report the effect of paste type of demineralized bone matrix (DBM) on augmentation of maxillary sinus using clinical parameters.
Sinus augmentation with DBM was performed on 5 maxillary sinuses. This study included 5 patients, 4 men and 1 woman, aged from 41 to 67 years (mean age 55 years). After an average of 6 months' healing period, a core bone was obtained and stained for histologic analysis.
All implants showed favorable osseointegration, and final restorations were completed without failure in all cases. Histologically, new bone formation was active around grafted bone and grafted bone was well integrated to the newly formed bone matrix. In histomorphometric analysis, vital bone volume was 25.2 +/- 11.9%.
The DBM paste is clinically useful for the increase of bone volume in sinus augmentation, because of its favorable effect of new bone formation and easy handling.
本研究旨在通过临床参数报告脱矿骨基质（DBM）糊剂对上颌窦增高的效果。
对5个上颌窦进行DBM窦腔增高术。本研究纳入5例患者，4例男性和1例女性，年龄41至67岁（平均年龄55岁）。经过平均6个月的愈合期后，获取核心骨并进行染色以进行组织学分析。
所有种植体均显示出良好的骨整合，所有病例均成功完成最终修复，无失败情况。组织学上，移植骨周围新骨形成活跃，移植骨与新形成的骨基质良好整合。在组织形态计量分析中，活性骨体积为25.2±11.9%。
DBM糊剂因其对新骨形成的良好作用和易于操作，在临床上对上颌窦增高术中骨量增加是有用的。
