目前,一种新的非减色钻井技术，称为骨致密化(OD)，已经开发了。它涉及使用特殊设计的钻头，这些钻头具有逆时针旋转的大负切割角度，通过塑性骨变形引起膨胀，从而将自体骨压实到截骨壁，这提高了植入物的主要稳定性。本系统综述旨在确定与常规钻孔（CD）技术相比，OD技术是否可以增加上颌骨后部区域牙科植入物的主要稳定性。截至2022年6月30日，共搜索了5个数据库。纳入标准包括观察性临床研究，随机和非随机对照试验，人体体内研究，比较OD和CD，通过植入物稳定性商（ISQ）测量上颌骨后部植入物的主要稳定性。用于评估偏倚风险的工具是RoB2和NewcastleOttawa量表（NOS）。七篇文章符合纳入标准，其中4个被分类为低偏倚风险，3个被分类为中等偏倚风险。OD技术在所有研究中始终显示出73KHz的平均ISQ值，而CD的平均值为58.49kHz（5篇文章的p<0.001）。可以得出结论，与CD相比，OD改善低密度骨基线时的主要稳定性，比如上颌骨.
Currently, a new non-subtractive drilling technique, called osseodensification (OD), has been developed. It involves using specially designed drills with large negative cutting angles that rotate counterclockwise, causing expansion through plastic bone deformation, thus compacting the autologous bone to the osteotomy walls, which improves the primary stability of the implant.The present systematic
review aimed to determine whether the OD technique can increase the primary stability of dental implants in the posterior maxilla region as compared to the conventional drilling (CD) technique.Five databases were searched up to June 30, 2022. The inclusion criteria embraced observational clinical studies, randomized and non-randomized controlled trials, human studies in vivo, comparing OD and CD, with the measurement of the primary stability of implants in the posterior maxilla region by means of the implant stability quotient (ISQ). The tools used to assess the risk of bias were RoB 2 and the NewcastleOttawa Scale (NOS).Seven articles met the inclusion criteria, with 4 classified as having a low risk of bias and 3 with a moderate risk of bias. The OD technique consistently demonstrated an average ISQ value of 73 KHz across all studies, whereas CD yielded an average value of 58.49 kHz (p < 0.001 for 5 articles).It can be concluded that in comparison with CD, OD improves primary stability at baseline in low-density bone, such as the maxilla.
