AIM
The literature review on assessment of lingual concavities in posterior mandibula with CBCT to prevent complications such as perforations during dental implant placement.
METHODS
The electronic search of full-text articles on lingual concavity studies with CBCT was performed. The data on the prevalence, depth and angle of concavities was analyzed.
RESULTS
The analysis included 5 articles from 2011 to 2016 years. Totally 1713 mandibular concavities were evaluated in 1232 patients. The prevalence was 46.7-68%; mean depth was from 2.4 mm to 5.4 mm; and the mean angle varied from 143 to 156.6 degrees.
CONCLUSION
Though morphologic data of lingual concavities showed similar pattern it is necessary to provide CBCT evaluation prior to dental implant placement to define available bone and its morphology. It is recommended to use guided surgery if U-type is evident.
目的
通过锥形束计算机断层扫描（CBCT）评估下颌后牙区舌侧骨凹陷，以预防牙种植体植入过程中穿孔等并发症。
方法
对使用CBCT进行舌侧骨凹陷研究的全文文章进行电子检索。分析凹陷的患病率、深度和角度数据。
结果
分析纳入了2011年至2016年的5篇文章。共对1232例患者的1713个下颌骨凹陷进行了评估。患病率为46.7% - 68%；平均深度为2.4毫米至5.4毫米；平均角度在143度至156.6度之间。
结论
尽管舌侧骨凹陷的形态学数据显示出相似模式，但在牙种植体植入前仍有必要进行CBCT评估，以确定可用骨及其形态。如果U型明显，建议使用引导手术。
