Parafunctional forces are a potential risk factor for implant-related complications. This study aimed to evaluate the possible relationship of bruxism with implant-related complications and marginal bone loss (MBL).
In this prospective cohort study, patients were divided into two groups with and without bruxism, and received single-tooth implants in the posterior mandible. Patients in the bruxer group were requested to use a customized fabricated night guard. Bone quality was also assessed based on CBCT scans. The MBL, crown detachment, and porcelain fracture were evaluated, and clinical assessments were made at the 12-month follow-up.
Seventy patients were studied in two groups ( = 35 in each group). None of the implants in any of the two groups showed pain, sensitivity, suppuration, exudation, clinically detectable mobility, or peri-implant radiolucency. No significant difference was observed between the two groups in the mean MBL at the 12-month follow-up ( = 0.60). Regarding bone quality, there was no significant difference in the mean MBL among different types of bone qualities ( = 0.66). There were no significant differences regarding crown detachment and porcelain fracture between the two groups either ( = 0.32 and = 0.30, respectively).
According to the results of this study, dental implant treatment according to the suggested protocol in bruxers yielded promising outcomes.
副功能力是种植相关并发症的一个潜在风险因素。本研究旨在评估磨牙症与种植相关并发症及边缘骨丢失（MBL）之间可能存在的关系。
在这项前瞻性队列研究中，患者被分为有磨牙症和无磨牙症两组，并在下颌后部接受单颗牙种植。磨牙症组的患者被要求使用定制的夜磨牙垫。还根据锥形束计算机断层扫描（CBCT）评估骨质量。评估MBL、牙冠脱落和瓷裂情况，并在12个月随访时进行临床评估。
两组共研究了70例患者（每组35例）。两组中的任何种植体均未出现疼痛、敏感、化脓、渗出、临床可检测到的松动或种植体周围透射影。在12个月随访时，两组的平均MBL无显著差异（=0.60）。关于骨质量，不同类型骨质量的平均MBL也无显著差异（=0.66）。两组之间在牙冠脱落和瓷裂方面也无显著差异（分别为=0.32和=0.30）。
根据本研究结果，按照建议方案对磨牙症患者进行牙种植治疗取得了良好的效果。
