The realisation of a bridgework involves a direct action on the gingival marginal edge. It is submitted to peremptoriness of execution that one of the objectives is to respect the periodontium with a great rigour. In the opposite case it can become a greater aggression agent, source of prosthetic failures we carried out this report in order to evaluate in the framework of a pedagogic operational programme of crown and bridge prosthesis, the superficial periodontal risks linked to the preparation of the abutment teeth and to the prosthetic chain. We examined a randomised sample of 50 patients chosen from the Dakar LOS prosthetic consultation. On the periodontium initially sound we noted inflammatory lesions of the superficial periodontium from the beginning to the end of the treatment we used the Russel periodontal index. The whole individual scores summarised on a collective chart have been submitted to the statistical analysis of the independence by using the chi-square test. The population consulting in bridge work at the Dakar LOS is relatively young, 33 years in a average with a sex ratio of 1.17 and it shows a moderate (60% of the cases) and severe periodontal seizure (40% of the cases) dealing significantly with the type of prosthesis and the axial and occlusal morphology of the prosthesis pieces. This study shows that prosthesis rehabilitation in the frame work of a clinical training at the Dakar I.O.S. includes relatively high risks of periodontium aggression that we would minimise by setting more correctly the indications of the bridge work and by bringing more rigour to the record and the postpone of the patients occlusion in the laboratory conception of the prosthesis pieces.
制作桥体修复体需要直接作用于牙龈边缘。制作过程必须严格执行，目标之一是高度严谨地保护牙周组织。否则，它可能成为更具侵害性的因素，导致修复失败。我们开展本报告，以便在冠桥修复体教学操作计划框架内，评估与基牙预备及修复体链相关的浅表牙周风险。我们从达喀尔LOS修复咨询中随机抽取了50名患者作为样本。对于最初牙周状况良好的患者，我们使用Russel牙周指数记录从治疗开始到结束时浅表牙周组织的炎症病变情况。汇总在一张集体图表上的所有个体分数，通过卡方检验进行独立性统计分析。在达喀尔LOS进行桥体修复咨询的人群相对年轻，平均年龄33岁，性别比为1.17，其中中度牙周病变（60%的病例）和重度牙周病变（40%的病例）显著与修复体类型以及修复体部件的轴向和咬合形态有关。本研究表明，在达喀尔I.O.S.临床培训框架内进行的修复体康复治疗存在相对较高的牙周组织侵害风险，我们可以通过更正确地设定桥体修复的适应证，以及在修复体部件的实验室设计中更严格地记录和调整患者的咬合，来将这些风险降至最低。
