Resumo: |
With the growing expansion of implant surfaces and the need for greater speed of osseointegration, methods of analysis of bone tissue and implant surface as well as the quality of the bone implant contact (BIC), they are increasingly being explored by researchers. The aim of this study is to show detail and describe a bone preservation protocol for making implants samples with and without implants without any harm or damage, or the bone tissue or the properties of the metal, preserving the BIC. In a second step, the samples prepared by the protocol preservation were compared with those made by histological analysis method for staining for HE, considered the gold standard for living tissue. Eight samples were used for bone tissue with implants in rabbit tibia and more four fragments of jaws without implants of the same rabbits. Samples with and without implants were made by the two protocols, after preparation of the test specimens, analysis by optical microscopy of transmission and reflection through scanned images were made. Each protocol had advantages when the results were analyzed individually in the implants without samples, becoming further analysis. However, for samples with implants, analysis only by histological method cannot bring good results, while the bone preservation method showed excellent results for osseointegration analysis, bone formation and bone implant interface. It follows that the bone preservation protocol is an excellent method for analyzing samples with implants, and can be complementary to histology, in analysis bone samples without implants. The histological method is not sufficient for analysis of bone formation and bone implant interface. |
