The aim of this study was to evaluate the periodontal and prosthodontic complications of multiple freestanding implants in the posterior jaws for up to 1 year of function.
Eight patients received 20 implants posterior to canines. Two or more implants were consecutively inserted to each patient. Single crowns were delivered onto the implants. Marginal bone loss, implant mobility, probing depth, and screw loosening were examined to evaluate the clinical success of such restorations for maximum 1 year of functional loading.
All the implants performed well during the observation period. Neither periodontal nor prosthodontic complications were found except a slight porcelain chipping. While the marginal bone level was on average 0.09 mm lower around the implant after 6 months of loading, it was 0.15 mm higher after 1 year.
Within the limits of this investigation, separate single-tooth implant restorations to replace consecutive missing teeth may clinically function well in the posterior jaw.
本研究旨在评估长达 1 年功能使用期间后牙区多个独立种植体的牙周和修复并发症。
8 名患者在尖牙后区植入 20 颗种植体。每位患者连续植入 2 颗或更多种植体。在种植体上制作单冠。评估此类修复体的临床成功率，检查边缘骨丧失、种植体动度、探诊深度和螺丝松动情况，最长观察 1 年。
所有种植体在观察期间表现良好。除了轻微的瓷崩外，未发现牙周或修复并发症。负荷 6 个月后，种植体周围边缘骨水平平均降低 0.09mm，1 年后升高 0.15mm。
在本研究范围内，用于替代连续缺失牙的单个种植体修复体在后牙区可能具有良好的临床功能。
