Background and Aim: Nowadays, reconstruction and replacement of the missed teeth with prosthesis supported by intra – bony dental implants has become a scientific and routine method in Iran and other parts of the world. The aim of this retrospective study was to evaluate the clinical parameters of prosthesis supported by dental implants among partial and complete edentulous patients with maxillofacial traumatic disorder.
Materials and Methods: In this observational analytic – descriptive study, 45 patients with martial maxillofacial injuries, treated with soft and hard tissue grafts at the site of dental implants, were evaluated at the end of four years of prosthetic treatment on total number of 214 implants. Data were analyzed statistically using one – way repeated ANOVA and Friedman tests.
Results: Bleeding index in 63% of implants and gingival index in 30% of implants were decreased in the forth year comparing to the beginning of the study (P<0.01), P<0.001). Initially, the means of sulcular depth and periodontal attachment level were 2.67±99 mm and 5.54±1.65 mm, respectively where as after four years the latter was increased to 6.08±2.21 mm and the former to 3.01±1.73 mm (P<0.04).
Conclusion: The rate of implants success after four years of loading was 95% showing that dental implants have enough efficacy for dental reconstruction of patients with maxillofacial traumatic disorders.
