Abstract

AIM

The present study was done to analyze the risk factors associated with dental implants in its survival rate.

MATERIALS AND METHODS

The present study was conducted on 208 patients with 425 dental implants placed. Patients were divided into four groups: group I (diabetes), group II (periodontitis), group III (smoking), and group IV (bruxism). All patients were followed for 8 to 10 years for the survival rates.

RESULTS

Out of 425 dental implants, 145 were inserted in 72 males and 280 in 136 females. The difference was significant (p = 0.01). Group I had 16 males and 36 females, group II had 20 males and 32 females, group III had 28 males and 24 females, and group IV had 8 males and 44 females. The difference was statistically significant (p < 0.05). Out of 425 implants, 90 (21.17%) had failures: 24 dental implants (29%) in group I, 22 dental implants (15.2%) group II, 34 dental implants (27%) in group III, and 10 dental implants (13%) in group IV showed failure. The difference was significant (p < 0.05). Success rate was 70.7% in group I, 83.3% in group II, 80.9% in group III, and 86.3% in group IV. The difference was nonsignificant (p > 0.05).

CONCLUSION

Diabetes, periodontitis, bruxism, and smoking are among various causative factors which affect the survival rate of dental implants. These are risk factors leading to implant failures.

CLINICAL SIGNIFICANCE

Diabetes, periodontitis, bruxism, and smoking are among various causative factors which affect the survival rate of dental implants.

摘要

目的

本研究旨在分析与牙种植体存活率相关的风险因素。

材料与方法

本研究对208例患者植入的425颗牙种植体进行了研究。患者分为四组：第一组（糖尿病）、第二组（牙周炎）、第三组（吸烟）和第四组（磨牙症）。对所有患者随访8至10年以观察存活率。

结果

在425颗牙种植体中，72名男性植入了145颗，136名女性植入了280颗。差异具有统计学意义（p = 0.01）。第一组有16名男性和36名女性，第二组有20名男性和32名女性，第三组有28名男性和24名女性，第四组有8名男性和44名女性。差异具有统计学意义（p < 0.05）。在425颗种植体中，90颗（21.17%）出现失败：第一组24颗牙种植体（29%）失败，第二组22颗牙种植体（15.2%）失败，第三组34颗牙种植体（27%）失败，第四组10颗牙种植体（13%）失败。差异具有统计学意义（p < 0.05）。第一组成功率为70.7%，第二组为83.3%，第三组为80.9%，第四组为86.3%。差异无统计学意义（p > 0.05）。
