RESUMO
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.
