Objective: The aim of this article is to compare two surface treatment types of the dental implants inserted in tibiae of rabbits on the early stages of the bone repair considering the pattern of maturation of collagen fibers and the osseointegration process.
Materials and methods: 10 modSAE (sandblast and acid etched modified) and 10 AO (anodic oxidation) implants were evaluated such as bone-implant contact (BIC), and collagen fiber orientation verified by circular polarized light (BICCPL). The results were measured at 7, 21 and 42 postoperative days.
Results: The modSAE implants induced greater BIC at all times observed. The BICCPL analysis revealed the both implants showed a maturation pattern collagen fiber formation. However, BICCPL values of modSAE were higher than AO values at 21 days.
Conclusions: In conclusion, the topography and surface characteristic of modSAE implant showed a tendency to improve bone tissue integration and also contributes to maturation of collagen fibers. This fact was evidenced at 21 days. The study shows the influence of topography and surface treatment of titanium dental implants in different stages of bone repair.
