BackgroundThere is limited evidence on the effect of osseodensification drilling (OD) on alveolar ridge dimension changes and implant stability compared to standard drilling (SD). The purpose of this study was to compare the effect of both drilling protocols on ridge dimensional changes and implant stability.MethodsFifteen patients were recruited for a total of 20 pairs of implants. Pre‐ and postdrilling ridge widths were measured at the crest and 5 and 10 mm apical to the crest, using a premarked surgical guide as a reference to standardize recordings. Following implant placement, insertion torque and implant stability quotients (ISQ) were recorded. ISQ were also recorded at 3, 6, and 12 weeks post‐op. Six‐month post‐op changes in buccal bone thickness (BBT) were measured via pre‐op and post‐op cone beam computed tomography (CBCT) superimposition analysis.ResultsGreater ridge width changes were observed at the crest and 5 mm apical from the crest, favoring OD, with no difference at 10 mm. When comparing BBT 6 months post‐op, OD maintained BBT better than SD. Additionally, greater insertion torque, ISQ, and high implant stability (HIS) were observed following OD compared to SD.ConclusionOD results in greater ridge dimensional changes compared to SD following osteotomy preparation, predictably maintains BBT and reduces the risk of buccal dehiscence and resorption, obtains superior torque at placement, higher ISQ values, and a greater number of implants achieving HIS, which is maintained throughout the entire healing period.

利用骨增化方案的脊尺寸变化和植入物稳定性：一项随机临床试验


背景与标准钻孔 （SD） 相比，关于骨增化钻孔 （OD） 对牙槽嵴尺寸变化和植入物稳定性影响的证据有限。本研究的目的是比较两种钻孔方案对屋脊尺寸变化和种植体稳定性的影响。方法招募 15 例患者，共 20 对植入物。在嵴处和嵴顶端 5 和 10 mm 处测量钻孔前和钻孔后的脊宽度，使用预先标记的手术导板作为标准化记录的参考。种植体植入后，记录插入扭矩和种植体稳定性商 （ISQ）。ISQ 也在术后 3 、 6 和 12 周记录。通过术前和术后锥形束计算机断层扫描 （CBCT） 叠加分析测量术后 6 个月颊骨厚度 （BBT） 的变化。结果在嵴处观察到更大的脊宽变化和距嵴 5 mm 的顶端，有利于 OD，在 10 mm 处没有差异。当比较术后 6 个月 BBT 时，OD 维持 BBT 的效果优于 SD。此外，与 SD 相比，OD 后观察到更大的插入扭矩、ISQ 和高植入物稳定性 （HIS）。结论截骨术准备后与 SD 相比，OD 导致更大的嵴尺寸变化，可预测地维持 BBT 并降低颊裂开和吸收的风险，在放置时获得卓越的扭矩，更高的 ISQ 值，以及更多的植入物实现 HIS，这在整个愈合期间保持不变。
