The aim of this retrospective study was to evaluate the effect of removable partial dentures in periodontal abutment teeth in relation to the type of denture support and design of RPD in a five-year worn period. Methods : A total of 64 patients with removable partial dentures (RPDs), participated in this study. It were examined ninety-one RPDs. There were seventy-five RPDs with clasp-retained and sixteenth were RPDs with attachments. There were 28 females and 36 males, aged between 40-64 years, 41 maxillary and 50 mandible RPDs. For each subjects the following data were collected: denture design, denture support, and Kennedy classification. Abutment teeth were assessed for plaque index (PI), calculus index (CI), blending on probing (BOP), probing depth (PD), gingival recession (GR), tooth mobility (TM). Level of significance was set at p<0.05. Results : According to denture support of RPD, BOP, PD, PI, GR, CI and TM-index showed no statistically significant difference. Based on the denture design of RPD's, BOP, PD, PI, CI, and TM-index proved no statistically significant difference. Except GR-index according to denture design confirmed statistically significant difference in RPD with clasp p<0.01. The higher values of all periodontal parameter as BOP, PD, PI, CI and TM were in patients with RPD's with claps comparing with RPD's with attachment. Conclusion : RPD's with clasp increased level of gingival inflammation in regions covered by the dentures and below the clasp arms in abutment teeth.
这项回顾性研究的目的是评估可摘局部义齿在五年使用期内对牙周基牙的影响，这与义齿支持类型和可摘局部义齿的设计有关。方法：共有64例佩戴可摘局部义齿（RPD）的患者参与了本研究。共检查了91副RPD。其中75副为卡环固位式RPD，16副为附着体式RPD。患者中有28名女性和36名男性，年龄在40 - 64岁之间，上颌RPD有41副，下颌RPD有50副。为每位受试者收集以下数据：义齿设计、义齿支持和肯尼迪分类。对基牙进行菌斑指数（PI）、牙石指数（CI）、探诊出血（BOP）、探诊深度（PD）、牙龈退缩（GR）、牙齿松动度（TM）的评估。显著性水平设定为p<0.05。结果：根据RPD的义齿支持情况，BOP、PD、PI、GR、CI和TM指数无统计学显著差异。基于RPD的义齿设计，BOP、PD、PI、CI和TM指数无统计学显著差异。除GR指数外，根据义齿设计，卡环固位式RPD存在统计学显著差异（p<0.01）。与附着体式RPD相比，卡环固位式RPD患者的所有牙周参数如BOP、PD、PI、CI和TM的值更高。结论：卡环固位式RPD增加了义齿覆盖区域以及基牙卡环臂下方牙龈炎症的程度。
