To evaluate and compare the impact of two removable partial dentures (acrylic removable partial denture [ARPD] and metallic removable partial denture [MRPD]) on periodontal tissues of the remaining teeth in the first 12 months of denture use.
This prospective clinical study included 40 patients, of which 20 received ARPDs, 20 received MRPDs, nine in the maxilla, and 11 in the mandible each. The patients were 45-65 years old; 24 were females, and 16 were males. Patients' demographic details, clinical indicators of periodontal complications, and biochemical measurement of Hs-C-reactive protein (CRP) and alkaline phosphatase (ALP) were considered. One-way analysis of covariance and Friedman were used to measure the differences in clinical periodontal parameters between the two types of dentures.
The significant findings were: Plaque index (PLAQ) scores for abutment teeth were higher in MRPD wearers (mean = 12.15) than ARPD wearers (mean = 10.45), whereas ARPD users had significantly higher mean bleeding on probing (BOP) values (mean = 1.5) than MRPD users (mean = 0.00); mobility of abutment teeth showed no significant differences; timeline comparisons showed a significant increase in the percentage of nonabutment teeth mobility in ARPD users (p = .028) compared with MRPD users over the same follow-up period (p = .102).
For a short-term period of 1 year, periodontal and mobility parameters have no significant impact on the abutment and nonabutment teeth of ARPD and MRPD users. Moreover, biochemical markers (CRP and ALP) for periodontal inflammation exhibited no significant difference in both types of dentures.
评估并比较两种可摘局部义齿（丙烯酸可摘局部义齿[ARPD]和金属可摘局部义齿[MRPD]）在义齿使用的前 12 个月对剩余牙齿牙周组织的影响。
这是一项前瞻性临床研究，共纳入 40 名患者，其中 20 名患者佩戴 ARPD，20 名患者佩戴 MRPD，上颌 9 例，下颌 11 例。患者年龄 45-65 岁；女性 24 例，男性 16 例。考虑了患者的人口统计学细节、牙周并发症的临床指标以及超敏 C 反应蛋白（hs-CRP）和碱性磷酸酶（ALP）的生化测量值。使用单因素协方差分析和 Friedman 检验来测量两种义齿之间临床牙周参数的差异。
显著发现：MRPD 佩戴者基牙的菌斑指数（PLAQ）评分较高（均值=12.15），而 ARPD 佩戴者的评分较低（均值=10.45）；ARPD 使用者的探诊出血（BOP）均值较高（均值=1.5），而 MRPD 使用者的 BOP 均值较低（均值=0.00）；基牙动度无显著差异；时间线比较显示，在相同的随访期内，ARPD 使用者的非基牙动度百分比显著增加（p=.028），而 MRPD 使用者的百分比没有显著增加（p=.102）。
在 1 年的短期时间内，ARPD 和 MRPD 使用者的基牙和非基牙的牙周和动度参数没有显著影响。此外，两种义齿的牙周炎症的生化标志物（CRP 和 ALP）也没有显著差异。
