The aim of the study was to evaluate patient-reported effects of treatment with fixed dental prostheses (FDP) and removable dental prostheses (RDP) and relate the change in Oral Health Related Quality of Life (OHRQoL) to the type of treatment and objective dental variables of aesthetics and mastication. Additionally, the purpose of the study was to identify aspects of impairment and improvement that the treatments caused. Fixed dental prostheses treatment was performed in 200 patients and RDP treatment in 107 patients. Gender, age, region of replacement, and number of teeth present and replaced were obtained. The participants completed the Oral Health Impact Profile 49 (OHIP-49) before and after treatment. A control group with no need for dental treatment also completed the OHIP-49. All participants had a significant improvement in OHRQoL. The improvement was higher for the RDP group than the FDP group. Removable dental prostheses that replaced only masticatory teeth did not improve the OHRQoL significantly. The improvement in OHRQoL for both the FDP and RDP groups was not at the level of the control group. Higher age was associated with lower improvement in OHRQoL. Higher age, being a woman and having teeth replaced in the aesthetic zone were associated with deterioration in OHRQoL. Both RDP treatment and FDP treatment were associated with a reduction in the problems most frequently reported before treatment. Treatment with RDP was associated with new problems caused by the RDP. Fixed dental prostheses and RDP treatments improved OHRQoL and reduced the number of problems. The RDP participants improved more than the FDP participants.
本研究旨在评估固定义齿（FDP）和可摘局部义齿（RDP）治疗对患者的影响，并将口腔健康相关生活质量（OHRQoL）的变化与治疗类型和美观及咀嚼相关的客观牙科变量联系起来。此外，本研究的目的是确定治疗引起的损害和改善方面。在 200 名患者中进行了 FDP 治疗，在 107 名患者中进行了 RDP 治疗。获取了性别、年龄、替代区域、存在和替代的牙齿数量。参与者在治疗前后完成了口腔健康影响简表 49（OHIP-49）。一个没有牙科治疗需求的对照组也完成了 OHIP-49。所有参与者的 OHRQoL 均显著改善。RDP 组的改善程度高于 FDP 组。仅替代咀嚼牙齿的 RDP 并不能显著改善 OHRQoL。FDP 和 RDP 组的 OHRQoL 改善均未达到对照组的水平。较高的年龄与 OHRQoL 的较低改善相关。较高的年龄、女性以及在美学区域替换牙齿与 OHRQoL 的恶化相关。RDP 治疗和 FDP 治疗均与治疗前报告的大多数问题数量减少相关。RDP 治疗与 RDP 引起的新问题相关。RDP 治疗和 FDP 治疗均改善了 OHRQoL，并减少了问题数量。RDP 组的改善程度大于 FDP 组。
