Abstract

Purpose: Occlusal overload can cause late implant loss. However, whether the magnitude of the occlusal force is a risk factor for late implant loss remains unclear. Thus, this clinical study aimed to determine the relationship between the gonial angle (GoA), which is associated with the magnitude of occlusal force, and late implant loss.

Methods: All implants with fixed prostheses placed at the Niigata University Hospital between April 2006 and August 2019 were included in this retrospective study. The implants with and without late loss were compared. Relevant variables, including smoking habits, diabetes mellitus status, remaining dentition, implant length and diameter, prosthesis design, retention systems, splinting, and GoA were assessed. Log-rank test and Cox proportional hazards regression analysis were used to estimate the adjusted hazard ratio (aHR) and to calculate the corresponding 95% confidence intervals (CI) for late implant loss.

Results: A total of 919 patients (349 men and 570 women) with 2512 implants were included in this study. Cox proportional hazards regression analysis revealed that a 10° decrease in the GoA (aHR, 1.588; 95% CI, 1.115-1.766; P = 0.010), smoking habits (aHR, 3.909; 95% CI, 2.131-7.168; P < 0.001), and male sex (aHR, 2.584; 95% CI, 1.376-4.850; P = 0.003) were significantly associated with late implant loss.

Conclusions: Within the limitations of this retrospective study of 2512 implants, smaller GoA, smoking habits, and male sex were risk factors for late implant loss.

盂角与晚期种植体脱落：回顾性临床研究

目的：咬合力过大可能导致种植体晚期脱落。然而，咬合力的大小是否是种植体晚期脱落的风险因素仍不清楚。因此，本临床研究旨在确定与咬合力大小相关的盂角 (GoA) 与种植体晚期脱落之间的关系：这项回顾性研究纳入了 2006 年 4 月至 2019 年 8 月期间在新潟大学医院植入固定修复体的所有种植体。对有和没有晚期脱落的种植体进行比较。评估了相关变量，包括吸烟习惯、糖尿病状况、剩余牙列、种植体长度和直径、修复体设计、固位系统、夹板和GoA。采用对数秩检验和考克斯比例危险回归分析来估算晚期种植体缺失的调整危险比（aHR），并计算相应的95%置信区间（CI）：本研究共纳入了 919 名患者（男性 349 名，女性 570 名），2512 个种植体。Cox比例危险回归分析显示，GoA下降10°（aHR，1.588；95% CI，1.115-1.766；P = 0.010）、吸烟习惯（aHR，3.909；95% CI，2.131-7.168；P < 0.001）和男性性别（aHR，2.584；95% CI，1.376-4.850；P = 0.003）与晚期种植体脱落显著相关：在这项包含 2512 个种植体的回顾性研究中，较小的 GoA、吸烟习惯和男性性别是导致种植体晚期脱落的风险因素。

期刊介绍： Journal of Prosthodontic Research is published 4 times annually, in January, April, July, and October, under supervision by the Editorial Board of Japan Prosthodontic Society, which selects all materials submitted for publication. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. The Journal will cover all diagnostic and clinical management aspects necessary to reestablish subjective and objective harmonious oral aesthetics and function. The most-targeted topics: 1) Clinical Epidemiology and Prosthodontics 2) Fixed/Removable Prosthodontics 3) Oral Implantology 4) Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology) 5) Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism) 6) Orofacial Pain and Temporomandibular Disorders (TMDs) 7) Adhesive Dentistry / Dental Materials / Aesthetic Dentistry 8) Maxillofacial Prosthodontics and Dysphagia Rehabilitation 9) Digital Dentistry Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, of orofacial trauma, or of a variety of dental and oral diseases and orofacial pain conditions. Reviews, Original articles, technical procedure and case reports can be submitted. Letters to the Editor commenting on papers or any aspect of Journal of Prosthodontic Research are welcomed.
