Less residual alveolar bone at extraction site at esthetic and functional tooth position is the main limitation in placing a dental implant, especially at long-span edentulous ridges. This needs ridge augmentation.
To assess bone width gain and implant stability following narrow ridge augmentation using the vertical ridge split technique.
In 22 subjects within the age group of 20-60 years and the mean age of 38.46 years. The vertical ridge split technique was done in all subjects for horizontal ridge augmentation. Paraesthesia, pain/discomfort, mobility, and radiographic crestal bone width were assessed 6 months postoperatively. The data were described as mean and standard deviation along with number and percentage. Paired -test was also used keeping the level of significance at < 0.05.
Implant stability was seen in 86.36% ( = 19) study subjects and were not stable in 13.63% ( = 3) subjects. Bone width preoperatively was in the range of 3.1-4.4 mm with the mean value of 3.64 ± 0.41. Postoperatively, the bone width increased and was in the range of 5.2-6.3 mm with the mean value of 5.62 ± 0.45 mm. This increase postoperatively was statistically significant with a value of <0.001.
The present study concludes that acceptable success results are seen using the ridge split technique with simultaneous dental implants placement in both atrophic maxilla and mandible.
在美观和功能牙位的拔牙位点处，剩余牙槽骨较少是种植牙植入的主要限制因素，尤其是在长跨度无牙颌牙槽嵴处。这就需要进行牙槽嵴增量术。
评估使用垂直牙槽嵴劈开技术进行窄牙槽嵴增量术后的骨宽度增加情况和种植体稳定性。
选取22名年龄在20 - 60岁之间，平均年龄为38.46岁的受试者。对所有受试者均采用垂直牙槽嵴劈开技术进行水平牙槽嵴增量。术后6个月评估感觉异常、疼痛/不适、松动度以及影像学检查的牙槽嵴顶骨宽度。数据以均值和标准差以及数量和百分比的形式呈现。还采用配对t检验，显著性水平设定为<0.05。
86.36%（n = 19）的研究对象种植体稳定，13.63%（n = 3）的对象种植体不稳定。术前骨宽度范围为3.1 - 4.4mm，平均值为3.64±0.41。术后骨宽度增加，范围为5.2 - 6.3mm，平均值为5.62±0.45mm。术后这种增加具有统计学显著性，p值<0.001。
本研究得出结论，在萎缩的上颌骨和下颌骨中同时植入牙种植体时，使用牙槽嵴劈开技术可获得可接受的成功结果。
