Removable partial dentures (RPD) used to restore the severely shortened mandible may adversely affect the remaining natural teeth and are associated with a low prevalence of use. This pilot study investigated patient satisfaction following restoration of mandibular shortened dental arches.
Sixty subjects with mandibular shortened dental arches entered a randomized controlled trial comparing two types of mandibular prostheses: bilateral free-end saddle RPDs and distal cantilever resin-bonded fixed partial dentures (FPD). Patient satisfaction was assessed using self-administered questionnaires before (baseline), 3 months after, and 1 year after provision of new prostheses.
Improvements in levels of general satisfaction with teeth, appearance of teeth, and perceived masticatory ability were significant for the FPD group. Significant improvements in perceived masticatory ability were noted for both groups. There were also significant improvements in perceived levels of comfort of mandibular prostheses in both groups. Changes in summary satisfaction scores indicated improved satisfaction for both treatment groups but suggested a larger clinical effect for the FPD group. Significant differences between treatment groups were not established.
Patient-based outcomes reported suggested that resin-bonded cantilever FPDs are an effective means of restoring the shortened mandibular dental arch in terms of patient comfort and acceptance.
用于修复严重缩短的下颌骨的可摘局部义齿(RPD)可能会对剩余天然牙产生不利影响,且其使用普及率较低。本初步研究调查了下颌缩短牙弓修复后的患者满意度。
60名下颌缩短牙弓的受试者进入一项随机对照试验,比较两种类型的下颌修复体:双侧游离端鞍式RPD和远中悬臂树脂粘结固定局部义齿(FPD)。在提供新修复体之前(基线)、之后3个月和1年后,使用自填式问卷评估患者满意度。
FPD组在牙齿总体满意度、牙齿外观和咀嚼能力感知方面有显著改善。两组在咀嚼能力感知方面均有显著改善。两组在下颌修复体舒适度感知水平上也有显著改善。总体满意度得分的变化表明两个治疗组的满意度均有所提高,但提示FPD组的临床效果更大。未确定治疗组之间的显著差异。
基于患者的报告结果表明,树脂粘结悬臂FPD在患者舒适度和接受度方面是修复缩短下颌牙弓的有效手段。
