To evaluate the maintenance requirements and the presence of prosthetic complications associated with marginal bone loss in the implant-retained bar and locator prostheses.
The study was executed between the years 2013 and 2018 on 114 patients who had undergone 283 dental implants. Patients were examined at follow-up recall sessions at 12 and 24 months after the placement of the dentures. The clinical examination also included intraoral and extraoral examinations of the patients; compatibility of the prostheses placed to about occlusion; an adaptation of the prosthesis to the tissues, health, and continuity of the soft tissues; complaints of the patients; implant success rates; and marginal bone loss, and prosthetic complications were evaluated at follow-up sessions, and statistical analysis was performed.
Locator attachment was placed in 94 patients with separated mandibles and maxillae, and a removable prosthesis with a bar attachment was placed in 20 patients. When evaluating the level of marginal bone loss regardless of the presence of complications, the area where the implant was set, the number of days after loading, and the type of retainer, it was found to be significant at the end of the 12th the 24th months. The results showed a significant relationship between the prosthesis type and the presence of complications at month 24 (p < 0.05). There was no significant relationship between the position of the denture and the presence of complications at month 12 (p > 0.05). There was no significant relationship between the location of the denture and the presence of complications at month 24 (p > 0.05).
Complications do not affect marginal bone loss, but the resulting marginal bone loss is the result of the patient not paying enough attention to oral hygiene. Routine inspections of the prosthesis after the completion of treatment seem to be important. If the requirements resulting from these checks are met, complications that may occur in the future will be prevented.
The maintenance requirements and the presence of prosthetic complications associated with marginal bone loss in the implant-retained bar and locator prostheses were evaluated. Complications occurred more frequently with the bar-supported removable implant prostheses.
评估种植体固位杆及定位器修复体边缘骨丢失相关的维护要求及修复并发症情况。
该研究于2013年至2018年间对114例接受了283颗牙种植体的患者进行。在义齿植入后12个月和24个月的随访复诊时对患者进行检查。临床检查还包括对患者的口内和口外检查；所放置修复体与咬合的匹配情况；修复体与组织的贴合度、软组织的健康状况及连续性；患者的主诉；种植体成功率；以及在随访时评估边缘骨丢失和修复并发症，并进行统计分析。
94例下颌骨和上颌骨分开的患者采用了定位器附着体，20例患者采用了带杆附着体的可摘修复体。在评估边缘骨丢失水平时，无论是否存在并发症、种植体植入部位、加载后天数及固位体类型，在第12个月和第24个月结束时均发现有显著差异。结果显示在第24个月时修复体类型与并发症的发生之间存在显著相关性（p＜0.05）。在第12个月时义齿位置与并发症的发生之间无显著相关性（p＞0.05）。在第24个月时义齿位置与并发症的发生之间无显著相关性（p＞0.05）。
并发症不影响边缘骨丢失，但边缘骨丢失是患者对口腔卫生关注不足所致。治疗完成后对修复体进行常规检查似乎很重要。如果满足这些检查的要求，未来可能发生的并发症将得到预防。
评估了种植体固位杆及定位器修复体边缘骨丢失相关的维护要求及修复并发症情况。杆支持式可摘种植修复体并发症发生率更高。
