Nowadays, dental implants permit consideration of as one of the most reliable therapeutic modalities during the establishment of any prosthetic treatment plan. In numerous clinical situations, implants can clearly contribute to a notable simplification of therapy, frequently enabling removable prostheses to be avoided, keeping it less invasive with respect to remaining tooth structure. The aim of the present study was to clinically assess the peri-implant and periodontal conditions after the placement of crowns in partially edentulous patients.
Twenty-five participants with 28 implant supported crowns were recruited in the study. After the insertion of suprastructure, meticulous scaling and root planing were performed on adjacent teeth which served as control. The clinical examination was carried out by a single examiner after placement of crowns at an interval of 1, 3, 6, 9, and 12 months and included the assessment of modified plaque index (mPlI), bleeding score, calculus score, probing pocket depth (PPD), and recession on the four aspects of each implant and adjacent teeth.
The mPlI, modified bleeding index (mBlI), calculus score, PPD, and recession decreased from 1 month to 12 months in both implants and in control teeth. The mean mPlI, mBlI, and calculus score were comparatively high in control teeth than implants. PPD was found to be more on implants than in control teeth. Recession was slightly higher in control teeth than implants throughout the study period, but it was not statistically significant.
An implant patient must always be enrolled in a supportive therapy program that involves recall visits at regular intervals.
如今，在制定任何修复治疗计划时，牙种植体可被视为最可靠的治疗方式之一。在众多临床情况下，种植体能显著简化治疗过程，常常避免使用可摘义齿，对剩余牙体结构的侵入性更小。本研究的目的是临床评估部分牙列缺损患者牙冠修复后种植体周围及牙周状况。
本研究招募了25名患者，共28颗种植体支持的牙冠。上部结构植入后，对作为对照的相邻牙齿进行细致的洁治和根面平整。由一名检查者在牙冠修复后1、3、6、9和12个月进行临床检查，包括评估每颗种植体及相邻牙齿四个部位的改良菌斑指数（mPlI）、出血评分、牙石评分、探诊深度（PPD）和牙龈退缩情况。
种植体和对照牙的mPlI、改良出血指数（mBlI）、牙石评分、PPD和牙龈退缩从1个月到12个月均有所下降。对照牙的平均mPlI、mBlI和牙石评分高于种植体。发现种植体的PPD高于对照牙。在整个研究期间，对照牙的牙龈退缩略高于种植体，但无统计学意义。
种植患者必须始终纳入支持性治疗计划，包括定期复诊。
