Prótese imediata sobre três implantes utilizando componentes protéticos angulados e implantes inclinados: resultados preliminares de um estudo retrospectivo

Abstract

Objective: To access and evaluate the outcomes of a treatment concept for rehabilitation of atrophic mandible associating immediate loading to tilted implants and angled abutments Materials and Methods: Records of six women and four men, mean age 61.5, were included. Radiographic data performed in 2 stages (T1 and T2) and data of patient satisfaction with the mandibular prosthesis, performed in 3 stages (T0, T1 and T2) by a satisfaction evaluation survey including questions on general satisfaction, retention, aesthetics and chewing up to 6 months, were accessed on records of patients previously submitted to rehabilitation with conventional dentures in the maxilla and immediate protocol on 3 implants in mandible. Radiographs were digitized and evaluated using the UTHSCSA Image Tool® software. Results: The survival rate of implants and prostheses were, respectively, 93.3% and 90.0%. After delivering the mandibular protocol, no significant differences on marginal bone loss over time (T1 and T2), for both tilted implants (Mesial - p=0.8890/Distal p=0.3740) as straight (Right/Left side - p=0.680). Regarding satisfaction with the prosthesis, significant differences were found between T0-T1 and T0-T2. No significant differences were observed when the comparison was made between T1-T2. Conclusion: The combination of angled abutments and tilted implants in the immediate rehabilitation of edentulous atrophic mandible seems to be a promising treatment.
