Abstract

Objectives: Can the type of implant rehabilitation influence peri-implant bone loss in case of full-arch mandibular prosthesis? The purpose of the study was to assess, using orthopantomograms (OPGs), the bone loss around implants in different types of implant-supported prosthetic rehabilitations and identify potential risk factors, associated with the number and location of implants, that may have an association with bone defects.

Methods: A radiographic study was conducted on 22,317 OPGs from 2010 to 2024. All OPGs with implant-supported prosthetic mandibular rehabilitations were included in the study.

Results: A total of 155 OPGs were evaluated, with peri-implant bone loss identified in 64 (41.3%). Distal implants (furthest from the center) across various positioning patterns were most susceptible to bone loss, with positions 3.6 and 4.6 demonstrating the most frequent occurrence (25 and 26 cases, respectively). The χ² test revealed significant associations between both the implant positioning pattern (p < 0.001) and number of implants (p < 0.001) with peri-implant bone loss. Also, by updating the sample of OPGs, increased susceptibility to bone resorption was found for implants placed distal to the mental foramen compared to mesial ones in full-arch-implant-supported fixed prostheses.

Conclusions: Prospective clinical studies will therefore be useful in investigating this finding further.

下颌全髋关节种植修复术后种植体周围骨质流失的回顾性影像学分析

研究目的种植体修复的类型是否会影响全拱下颌修复体的种植体周围骨质流失？本研究的目的是使用正位片（OPG）评估不同类型种植体支持修复的种植体周围骨质流失情况，并确定与种植体数量和位置相关的、可能与骨质缺损有关的潜在风险因素：2010年至2024年期间，对22317颗OPG进行了放射学研究。结果：共有 155 个 OPG 接受了种植体支持的下颌骨修复：共评估了155颗OPG，发现64颗（41.3%）种植体周围骨质流失。在各种定位模式中，远端种植体（距离中心最远）最容易出现骨质流失，其中3.6和4.6位置的种植体最容易出现骨质流失（分别为25和26例）。χ2检验显示，种植体定位模式（p < 0.001）和种植体数量（p < 0.001）与种植体周围骨质流失之间存在显著的相关性。此外，通过更新 OPGs 样本，还发现在全牙弓种植体支持的固定修复体中，种植体放置在种植孔远端比种植体放置在种植孔中段更容易发生骨吸收：因此，前瞻性临床研究将有助于进一步研究这一发现。
