Maintenance following implant treatment is essential to ensure long-term stability. Accordingly, the objective of this study was to investigate the factors leading patients to discontinue maintenance following implant treatment. Among the 729 patients that underwent implantation at the Department of Oral Implantology, Osaka Dental University Hospital from January 2008 to December 2012, 41 patients were excluded from the study. Exclusion criteria comprised patients without a superstructure attachment, those who only underwent maxillary sinus floor augmentation procedures and those who discontinued visiting the hospital prior to superstructure attachment. Treatment was discontinued in 181 patients. The rate of discontinuation was 26.6 %. The odds ratio (OR) in the adjustment model was 1.552 (95 % CI 1.078-2.236) in males when compared with females. When compared with those who were 30-64 years old, the OR was 5.818 (95 % CI 3.017-11.220) in those 29 years old or younger and 1.561 (95 % CI 1.021-2.386) in those 65 years old or older. Moreover, when compared with those with a O'Leary's Plaque Control Record of all teeth and superstructures (PCR) level of 20 % or less following superstructure attachment, the OR was 2.113 (95 % CI 1.471-3.035) in those with a PCR level of 20 % or more following superstructure attachment. It is highly important to decrease maintenance discontinuation, especially in patients aged 29 years old or younger with a PCR level of 20 % or more following superstructure attachment. Moreover, a support system must be developed to enable patients with difficulties visiting the hospital to continue their maintenance program.
种植治疗后的维护对于确保长期稳定性至关重要。因此，本研究的目的是调查导致患者在种植治疗后停止维护的因素。在2008年1月至2012年12月期间于大阪齿科大学医院口腔种植科接受种植的729例患者中，41例患者被排除在研究之外。排除标准包括没有上部结构附着的患者、仅接受上颌窦底提升手术的患者以及在上部结构附着之前停止就诊的患者。181例患者停止了治疗。停药率为26.6%。与女性相比，调整模型中男性的优势比（OR）为1.552（95%CI 1.078 - 2.236）。与30 - 64岁的患者相比，29岁及以下患者的OR为5.818（95%CI 3.017 - 11.220），65岁及以上患者的OR为1.561（95%CI 1.021 - 2.386）。此外，与上部结构附着后O'Leary全口牙齿及上部结构菌斑控制记录（PCR）水平在20%及以下的患者相比，上部结构附着后PCR水平在20%及以上的患者的OR为2.113（95%CI 1.471 - 3.035）。降低维护中断率非常重要，尤其是对于上部结构附着后PCR水平在20%及以上的29岁及以下患者。此外，必须建立一个支持系统，使难以就诊的患者能够继续他们的维护计划。
