Abstract

BACKGROUND

Substantial effort is dedicated to finding the most favorable parameters that will ensure low aftercare demands among edentulous patients wearing mandibular implant supported overdentures (MISODs). The purpose of this retrospective cohort study was to compare prosthetic aftercare between MISOD patients with a simultaneous (group A) vs. a three-week settling in period (group B) prior to attachment incorporation.

METHODS

Forty-five patients enrolled in this study. Two implants per patient were placed using a two-stage implant insertion protocol. Second-stage surgery was performed after three months. All patients received ball attachments using the direct (chairside) incorporation method. Twenty-two patients received their dentures with simultaneous attachment activation and the rest-twenty-three patients-after a three-week settling in period. Patients' files were scanned for aftercare visits. Outcome parameters included sore spot relief, attachment incorporation, and denture repair. Additionally, gingival index measurements were compared. Confounding factors included age, gender, and implant dimensions.

RESULTS

The mean follow-up for the entire cohort was 84 ± 21 months, and the range 39-120 months. The mean number of visits for group A vs. B respectively: pressure sores relieve (3.63 ± 0.84 vs. 3.71 ± 0.61, = 0.581), liner exchange due to loss of retention (2.09 ± 1.03 vs. 2.31 ± 1.04 = 0.487), and gingival index (1.3 ± 0.3 vs. 1.03 ± 0.2, = 0.653) exhibited no statistically significant differences between the tested groups. No statistically significant differences between the groups were also noted for the denture repair aftercare treatments ( = 0.318) and the independent variables including age, gender, and implant length.

CONCLUSIONS

Prosthetic aftercare in MISOD wearers is similar whether a simultaneous or a three-week settling in period for attachment incorporation is applied.

摘要

背景

人们致力于寻找最有利的参数，以确保佩戴下颌种植体支持覆盖义齿（MISOD）的无牙患者术后护理需求较低。这项回顾性队列研究的目的是比较在附着体安装前同时进行（A组）与经过三周适应期（B组）的MISOD患者的修复后护理情况。

方法

45名患者参与了本研究。每位患者使用两阶段种植体植入方案植入两颗种植体。三个月后进行二期手术。所有患者均采用直接（椅旁）安装法安装球帽附着体。22名患者在附着体激活的同时佩戴义齿，其余23名患者在经过三周适应期后佩戴义齿。扫描患者档案以查看术后护理就诊情况。结果参数包括痛点缓解、附着体安装和义齿修复。此外，还比较了牙龈指数测量结果。混杂因素包括年龄、性别和种植体尺寸。

结果

整个队列的平均随访时间为84±21个月，范围为39 - 120个月。A组和B组的平均就诊次数分别为：压疮缓解（3.63±0.84对3.71±0.61，P = 0.581）、因固位丧失进行衬垫更换（2.09±1.03对2.31±1.04，P = 0.487）以及牙龈指数（1.3±0.3对1.03±0.2，P = 0.653），在测试组之间均无统计学显著差异。在义齿修复后护理治疗（P = 0.318）以及包括年龄、性别和种植体长度在内的自变量方面，两组之间也未发现统计学显著差异。
