Chin implants have a long history, and its usage may be associated with mandibular bone resorption.
This report analyzed data on this topic from existing literature to evaluate the overall resorption rate and scientific impact in terms of citations.
PubMed, Web of Science, Scopus, and Google Scholar databases were searched to identify relevant publications. The search string was as follows: (chin) AND (augment OR implant) AND (resorb OR resorp) AND (bone OR osseous). A study was eligible if it recruited human subjects and reported resorption following any chin implantation based on radiographic examination.
Twenty-eight patient studies were identified. Publication year seemed to have no effect on the mean depth of bone resorption and its prevalence as reported by the studies. The increased mean number of follow-up years seemed to have no effect on its prevalence but seem to be associated with deeper bone resorption. The majority of the studies had <5 years of follow-up and reported a mean of <2 mm of bone resorption. The most cited study had 69 citations. Citations rarely came from radiology journals. A limitation was that unpublished data could not be analyzed.
Mandibular bone resorption caused by chin implants of various materials is a common phenomenon. Its recognition and studies with a longer follow-up period should be further promoted.
颏部植入物历史悠久，其使用可能与下颌骨吸收有关。
本报告分析了现有文献中关于该主题的数据，以评估总体吸收速率以及引用方面的科学影响。
检索了PubMed、科学网、Scopus和谷歌学术数据库以识别相关出版物。检索词如下：（颏部）AND（增大或植入物）AND（吸收或再吸收）AND（骨或骨质）。如果一项研究招募了人类受试者并根据影像学检查报告了任何颏部植入后的吸收情况，则该研究符合纳入标准。
共识别出28项患者研究。研究报告显示，发表年份似乎对骨吸收的平均深度及其发生率没有影响。随访年数的增加似乎对其发生率没有影响，但似乎与更深的骨吸收有关。大多数研究的随访时间<5年，报告的骨吸收平均深度<2 mm。被引用次数最多的研究有69次引用。引用很少来自放射学杂志。一个局限性是无法分析未发表的数据。
各种材料的颏部植入物导致的下颌骨吸收是一种常见现象。应进一步促进对其的认识以及进行更长随访期的研究。
