摘要
目的:探究Ⅳ期牙周炎老年患者后牙区种植体修复效果及种植体边缘垂直骨吸收(VBL)的影响因素.方法:回顾性分析2020年1月～2022年1月东营鸿港医院119例Ⅳ期牙周炎老年患者(共235个种植体)临床资料,观察后牙区种植体修复效果,采用多元线性回归分析确定影响种植体边缘VBL的因素.结果:首次复诊时,119例Ⅳ期牙周炎老年患者(种植体235个)后牙区种植体探诊深度为(2.45±0.70)mm、牙菌斑指数(1.42±0.51)、牙龈指数为(0.81±0.34)、平均VBL为(0.81±0.31)mm、OHIP-14评分为(45.36±5.17)分;不同性别、负载时间、牙周炎分级、复诊天然牙牙周状况、口腔卫生习惯以及吸烟与否的Ⅳ期牙周炎老年患者后牙区种植体边缘平均VBL比较,差异具有统计学意义(P＜0.05),而不同年龄、骨密度、复诊情况、牙列缺损分类、植体直径、种植牙位、种植附加手术、修复类型、冠根比、对颌牙类型、种植体类型的Ⅳ期牙周炎老年患者后牙区种植体边缘平均VBL比较,差异无统计学意义(P＞0.05);多元线性回归分析结果显示,性别、负载时间、复诊天然牙牙周状况、牙周炎分级、吸烟、不良口腔卫生习惯是影响Ⅳ期牙周炎老年患者后牙区种植体边缘平均VBL水平的因素(P＜0.05).结论:男性、负载时间≥1年、牙周炎复发、重度牙周炎、吸烟、不良口腔卫生习惯会提高Ⅳ期牙周炎老年患者后牙区种植体边缘VBL水平,临床需加以重视.
Abstract
Objective:To investigate the factors influencing the effect of implant restoration in the posterior region and vertical bone resorption(VBL)at the implant margin in elderly patients with stage Ⅳ periodontitis.Methods:Retrospective analysis of the clinical data of 119 elderly patients with stage Ⅳ periodontitis(235 implants in total)in Dongying Honggang hospital from January 2020 to January 2022 was performed to observe the effect of implant restoration in the posterior region,and the factors affecting VBL at the implant margins were also analyzed by multiple linear regression.Results:At the first follow-up,119 elderly patients with stage Ⅳ periodontitis(235 implants)showed a probing depth of(2.45±0.70)mm,plaque index(1.42±0.51),gingival index(0.81±0.34),mean VBL of(0.81±0.31)mm,and OHIP-14 score of(45.36±5.17)in the posterior region of the implants.Comparison of mean VBL of implant margins in posterior region of elderly patients with stage Ⅳ periodontitis with different gender,loading time,periodontitis grading,periodontal status of natural teeth on revision,oral hygiene habits,and smoking or non-smoking showed statistically significant differences(P＜0.05),while with different age,bone density,revision status,classification of dental defect,implant diameter,implant position,implant add-on surgery,type of restoration,crown-root ratio,type of opposing jaw teeth,and implant type,the difference was not statistically significant when comparing the mean VBL of implant margins in the posterior region of elderly patients with stage Ⅳ periodontitis(P＞0.05).The results of multiple linear regression analysis showed that gender,loading time,periodontal status of the natural teeth at follow-up,periodontitis classification,smoking,and poor oral hygiene habits were factors affecting the mean VBL level of implants in the posterior region of elderly patients with stage Ⅳ periodontitis(P＜0.05).Conclusion:Male,more than one year of loading time,periodontitis recurrence,severe periodontitis,smoking,and bad oral hygiene habits will increase the VBL level in the posterior dental implant margin of elderly patients with stage Ⅳ periodontitis,which should be paid attention to in clinic.
