EVALUATION OF THE SUCCESS RATES OF IMMEDIATE IMPLANT PLACEMENT IN ANTERIOR AND POSTERIOR REGIONS SUCCESS RATES OF IMMEDIATE IMPLANT: A RETROSPECTIVE STUDY

Abstract

Introdution: Immediate implants placement has shown contradictory results in the posterior region. Objective: The aim of the study was to compare the success rate and predictability of the short-term treatment using immediate implants in anterior and posterior regions. Methods: A total of 1000 dental charts were analyzed, of which 43 were included in the study: anterior (n=20) and posterior (n=23). The inclusion criteria were: tooth extraction indication, immediate singletooth implant placement and at least twelve months of follow-up with functional implant. The success rates were based on the criteria I. and II. from the health scale for dental implants proposed at the International Congress of Oral Implant Dentistry: no pain; no mobility, until 4 mm of bone loss, no exudate. P-value <0.05 was considered significant. Results: The total success rate of immediate implants was 97.7% for immediate implants in function for at least 12 months. The use of biomaterial (p=0.03) and temporary prosthesis (p<0.0001) were significantly higher in the anterior group. There was no significant difference in implant failure between groups (p=0.47). There was no statistical difference between the groups, considering age, sex, extraction reason, initial torque immediately following implant placement, treatment time and implant platform type (p> 0.05). Conclusion: It may be concluded that the anterior and posterior regions present a high shortterm success rate when the immediate implant technique was used.
