Narrow alveolar ridges pose a serious challenge for successful placement of endosseous implants and alveolar ridge widening procedure is indicated in cases of crest thickness of ≤4.0 mm. The study evaluated and compared, immediate and delayed techniques of implant placement using split crest technique to augment atrophic narrow alveolar ridges.
The study was carried out in 10 patients randomly divided into two groups of five each for immediate or delayed placement of implants. Implants were placed simultaneously after split crest procedure in immediate technique and after 3-4 weeks of healing in delayed technique. Data collected was statistically analyzed by SPSS version 22 using unpaired -test, ANOVA and Pearson's correlation with p value = 0.05.
Statistically significant (p = 0.000) difference was observed for implant stability at intra-op, 4 months and 6 months post-op between the two groups, however there was no statistically significant difference in amount of augmentation achieved between the two groups.
We observed that both the techniques were comparable on the basis of augmentation achieved, implant success and survival rates, whereas implant stability was significantly higher in delayed technique group.
狭窄的牙槽嵴对骨内种植体的成功植入构成严重挑战，当嵴厚度≤4.0毫米时，需进行牙槽嵴增宽术。本研究评估并比较了使用劈开嵴技术增加萎缩性狭窄牙槽嵴后立即和延迟植入种植体的技术。
该研究对10名患者进行，随机分为两组，每组5人，分别进行种植体的立即或延迟植入。在立即植入技术中，劈开嵴手术后立即植入种植体；在延迟植入技术中，在愈合3 - 4周后植入种植体。收集的数据使用SPSS 22版本进行统计学分析，采用独立样本t检验、方差分析和Pearson相关性分析，p值 = 0.05。
两组在术中、术后4个月和6个月时的种植体稳定性存在统计学显著差异（p = 0.000），然而两组之间实现的增宽量没有统计学显著差异。
我们观察到，在实现的增宽量、种植体成功率和存活率方面，两种技术具有可比性，而延迟植入技术组的种植体稳定性明显更高。
