Abstract

OBJECTIVES

To assess long-term (≥10 years) implant survival, peri-implant health, patients' satisfaction and oral health related quality of life (OHQoL) in oligodontia patients rehabilitated with implant-based fixed prosthodontics.

METHODS

All oligodontia patients treated ≥10 years previously with implant-based fixed prosthodontics at the University Medical Center Groningen, The Netherlands, were approached to participate. Clinical (plaque index, bleeding index, pocket probing depth) and radiographic (marginal bone level) data were collected between February and May 2016. Surgical implant details (e.g., bone augmentation) and implant loss were recalled from the medical records. Patients completed a satisfaction questionnaire (maximum score 10, high score favourable satisfaction) and the Oral Health Impact Profile (OHIP-NL49, maximum score 196, low score favourable satisfaction) to rate OHQoL. Implant survival was expressed according to Kaplan Meier. The Mann-Whitney U Test was used for the other analyses.

RESULTS

Forty-one patients had been treated with implant-based fixed prosthodontics (n = 258) ≥10 years previously. Cumulative 10-year implant survival of these 41 patients was 89.1% (95%CI 85.2-93.0%). Twenty-eight of them (n = 163 implants) were willing to visit us for additional clinical and radiographic assessments. In these 28 patients, highest peri-implant bone loss was observed for implants placed in augmented bone (p < 0.001). Peri-implant mucositis (65.4%) and peri-implantitis (16.1%) were rather common. Patients' satisfaction (8.3 ± 1.5) and OHIP-NL49 scores (32.6 ± 30.1) were favourable and not associated with number of agenetic teeth (≤10 versus >10).

CONCLUSIONS

Long-term survival, satisfaction and OHQoL results reveal that implant treatment is a predictable and satisfactory treatment modality for oligodontia, although peri-implant mucositis and peri-implantitis are common.

CLINICAL SIGNIFICANCE

This study showed unique long-term (≥10 years) results about implant survival, peri-implant health, patients' satisfaction and OHQoL in oligodontia patients rehabilitated with implant-based fixed prosthodontics.

摘要

目的

评估在接受种植体支持固定修复的少牙畸形患者中，长期（≥10 年）种植体存活率、种植体周围健康、患者满意度和口腔健康相关生活质量（OHQoL）。

方法

邀请荷兰格罗宁根大学医学中心接受过≥10 年前基于种植体的固定修复治疗的所有少牙畸形患者参加。在 2016 年 2 月至 5 月期间收集临床（菌斑指数、出血指数、牙周袋探针深度）和影像学（边缘骨水平）数据。从病历中回忆起手术植入物的详细信息（例如，骨增强）和植入物丢失。患者完成了满意度问卷（最高得分为 10，高分表示满意）和口腔健康影响简表（OHIP-NL49，最高得分为 196，低分表示满意），以评估 OHQoL。根据 Kaplan-Meier 表示种植体存活率。使用 Mann-Whitney U 检验进行其他分析。

结果

41 名患者接受了基于种植体的固定修复治疗（n=258），时间超过 10 年。这 41 名患者的 10 年累积种植体存活率为 89.1%（95%CI 85.2-93.0%）。其中 28 名患者（n=163 个植入物）愿意来我们这里进行额外的临床和影像学评估。在这 28 名患者中，植入在增强骨中的种植体观察到的最高边缘骨丧失（p<0.001）。种植体周围黏膜炎（65.4%）和种植体周围炎（16.1%）相当常见。患者满意度（8.3±1.5）和 OHIP-NL49 评分（32.6±30.1）良好，与无牙数（≤10 与>10）无关。
