The aim of this retrospective cohort study was to assess the effects of annual maintenance over a 7-year period on the peri-implant health of patients rehabilitated with overdentures using clinical and radiographic parameters.
In order to be considered for inclusion in the study, patients had to have been rehabilitated with overdentures that had at least two implants placed in the mandible and four implants in the maxilla. Patients were divided into two groups: group 1 comprised individuals who had undergone annual maintenance over the previous 7 years, and group 2 comprised those who had not attended any dental appointment over the previous 7 years. All patients were submitted to clinical peri-implant examinations and radiographic assessments.
Sixty-six patients received 396 implants of the external hexagon type, 132 in the mandible and 264 in the maxilla. Group 1 (44 patients with 264 implants) had a mean probing depth of 2.72 mm, while group 2 (22 patients with 132 implants) had a mean probing depth of 3.10 mm. It can be concluded that the mean of the variable probing depth is influenced by the presence of bleeding (P = .0005) and the implementation of maintenance (P = .0188), whereas plaque and local variables were not otherwise significant (P = .0605 and .0796, respectively).
In this study, it was possible to observe better clinical conditions in individuals who had attended annual appointments for maintenance purposes.
这项回顾性队列研究的目的是使用临床和影像学参数评估7年期间年度维护对使用覆盖义齿修复的患者种植体周围健康的影响。
为了被纳入本研究，患者必须使用覆盖义齿进行修复，且在下颌至少植入两颗种植体，在上颌至少植入四颗种植体。患者被分为两组：第1组包括在过去7年中接受年度维护的个体，第2组包括在过去7年中未进行任何牙科检查的个体。所有患者均接受了临床种植体周围检查和影像学评估。
66例患者接受了396颗外六角型种植体，其中下颌132颗，上颌264颗。第1组（44例患者，264颗种植体）的平均探诊深度为2.72mm，而第2组（22例患者，132颗种植体）的平均探诊深度为3.10mm。可以得出结论，探诊深度变量的平均值受出血情况（P = .0005）和维护措施的实施（P = .0188）影响，而菌斑和局部变量无其他显著影响（分别为P = .0605和.0796）。
在本研究中，可以观察到因维护目的而每年就诊的个体具有更好的临床状况。
