The purpose of this study was to clinically and radiographically compare implant-connected and tooth-connected implant-supported fixed-detachable mandibular partial dentures. Twenty partially edentulous patients (age range: 25 to 50 years) with mandibular Kennedy Class II configurations were equally divided into two groups receiving a three-unit, fixed-detachable, screw-retained partial denture. Group 1 comprised patients with unilateral missing mandibular molars and premolars. Two implants were placed at the mandibular first premolar and first molar areas. Group 2 comprised patients with missing mandibular molars and second premolars. An implant was placed at the mandibular first molar area, the first premolar was prepared, and a coping was cemented to the tooth with permanent cement. Each case was evaluated clinically and radiographically at baseline (partial denture insertion) and after 6, 12, and 24 months. Data were collected and statistically analyzed using repeated-measures one-way and two-way analysis of variance tests. There was no statistically significant difference between the two groups (P > .05). The implant-tooth-supported prosthesis provided an equally predictable treatment option compared to the totally implant-supported prosthesis in terms of implant survival and loss of marginal bone.
本研究的目的是从临床和影像学方面比较种植体连接式和牙连接式种植体支持的固定可摘下颌局部义齿。20例下颌Kennedy II类牙列缺损患者（年龄范围：25至50岁）被平均分为两组，接受一个三单位的固定可摘螺丝固位局部义齿。第1组包括单侧下颌磨牙和前磨牙缺失的患者。在下颌第一前磨牙和第一磨牙区域植入两颗种植体。第2组包括下颌磨牙和第二前磨牙缺失的患者。在下颌第一磨牙区域植入一颗种植体，预备第一前磨牙，并使用永久性粘结剂将桩核粘结到该牙上。在基线时（局部义齿戴入）以及6、12和24个月后，对每个病例进行临床和影像学评估。收集数据并使用重复测量单向和双向方差分析检验进行统计分析。两组之间无统计学显著差异（P>0.05）。在种植体存留率和边缘骨丧失方面，种植体-牙支持式修复体与全种植体支持式修复体相比，提供了同样可预测的治疗选择。
