附着龈重建对口腔种植修复的近期影响

Short term influence of attached gingival reconstruction on oral implant restoration

目的探讨附着龈重建在口腔种植修复中的近期效果及作用。方法选择2013年1月至2014年7月口腔种植修复患者98例109个种植牙和牙龈位点,均伴有附着龈缺乏,随机分为对照组和观察组,每组49例。对照组行口腔种植修复,观察组行种植修复并附着龈重建。观察两组治疗基本情况,并测量两组有效角化龈宽度,评估治疗后改良菌斑指数(m PI)、牙龈出血指数(BI)、探诊深度(PD)。结果观察组治疗后有效角化龈宽度为(2.58±0.34)mm,长于对照组[(2.04±0.28)mm],差异有统计学意义(P<0.05);观察组患者治疗后种植体m BI、PLI和PD分别为(1.27±0.80)分、(1.40±0.61)分和(2.23±0.26)mm,均低于对照组[(3.46±0.72)分、(3.39±0.54)分和(3.18±0.21)mm],差异有统计学意义(P<0.05)。结论附着龈重建在口腔种植修复中短期效果较好,能够增加牙龈的宽度,并有利于对修复后种植牙的保护,值得临床推广应用。

Objective To investigate the effect and function of the attached gingival reconstruction in oral implant restoration in short term. Methods From January 2013 to July 2014,98 patients with oral implant restorations,109 implant and the gingival sites,were selected and randomly divided into the observation group and the control group,with 49 cases in each group. The control group was given oral implant,and the observation group was given implant restoration and attached gingival reconstruction. The basic conditions of two groups were observed,and the effective gingival width of the two groups were measured,and then the modified plaque index（ m PI）,gingival bleeding index（ BI） and bleeding index（ BOP） were evaluated. Results The effective gingival width of the observation group after treatment was（ 2. 58 ± 0. 34）mm,which was longer than that in the control group[（ 2. 04 ± 0. 28） mm],the difference was significant（ P 0. 05）.MBI,PLI,PD of planting body in the observation group after treatment were respectively（ 1. 27 ± 0. 80）,（ 1. 40 ± 0. 61）and（ 2. 23 ± 0. 26） mm,which were lower than those in the control group [（ 3. 46 ± 0. 72）,（ 3. 39 ± 0. 54） and（ 3. 18 ±0. 21） mm],the differences were significant（ P 0. 05）. Conclusion The short term effect of the attached gingival reconstruction on oral implant repair is good,which can increase the width of the gum,and can help to protect the tooth after the restoration,so it is worthy of clinical application.
