Abstract
INTRODUCTION AND IMPORTANCE
The study aimed to present the long-term results of autologous and homologous micrografts for bone regeneration aimed at positioning dental implants after sinus lift augmentation surgeries, by combining autologous Rigenera® micrografts with poly(lactic-go-glycolic acid).
CASE PRESENTATION
A total of 5 patients (2 males and 3 females) from 36 to 71 years were involved in the observational study. All the patients showed a good health status system (ASA1 and 2), according to their clinical history with neither system diseases, nor under medication able to interfere with osseointegration.
CLINICAL DISCUSSION
The radiographic evaluations, after the implant placement and during the continuous follow-up upto 7 years, were carried out through periapical endoral x-rays. The survival and implant success rate was 100 %. Histological analyses were performed after 3 and 7 months after the surgical procedure.
CONCLUSION
No adverse events have been observed that can be traced back to the use of autologous micrografts with poly(lactic-go-glycolic acid), showing safety and predictable results even in long term.
