Discontinuation of implant maintenance is the main risk factor for implant failure. The purpose of this study was to identify factors associated with previous discontinuation and resumption of maintenance among implant patients. A questionnaire survey was sent to 171 patients receiving implant maintenance at a university hospital; 169 patients responded. To assess the effect of job status, 26 patients (15.4%) with a history of maintenance discontinuation were classified as employed and nonemployed. The main reasons for previously discontinuing maintenance were work issues (in employed respondents) and dissatisfaction with treatment skill or chairside manner (in nonemployed respondents). The main reasons for resuming maintenance were those related to dental treatment (in employed respondents) and awareness of the importance of maintenance (in nonemployed respondents). There were significant differences in relation to job status in the reasons reported for discontinuing and resuming maintenance (both P < 0.05). The present findings suggest that oral health professionals should consider these factors when assisting patients in reducing the risk of implant failure.

停止维持种植体是种植体失败的主要危险因素。这项研究的目的是确定与先前植入患者中止和恢复维持治疗有关的因素。向171例在大学医院接受种植体维护的患者进行了问卷调查；169例患者有反应。为了评估工作状况的影响，将26例具有维持中断病史的患者（15.4％）归类为已就业和未就业。以前中止维护的主要原因是工作问题（在被雇佣的受访者中）以及对治疗技能或主席方式的不满（在失业的受访者中）。恢复maintenance养的主要原因是与牙科治疗有关（在职受访者）和对maintenance养重要性的认识（在无业受访者中）。报告的停止和恢复维护的原因与工作状态之间存在显着差异（两者均P <0.05）。目前的发现表明，口腔保健专业人员在协助患者减少植入失败的风险时应考虑这些因素。
