title: Correlations between cyto-histopathological tissue changes at the dental implant interface and the degree of surface processing.
abstract: The bone tissue is a specialized connective tissue adapted for support and protection. The bone physiology is balanced by the interaction between mechanical and metabolic factors. Current research focuses on the bone remodeling process after the insertion of dental implants, because, after the primary healing of the wound caused by the creation of the new alveolus, the proliferation and differentiation of the osteoblasts and fibroblasts will tip the balance of the healing pattern toward bone regeneration or fibrous encapsulation. Knowing and identifying the components of the connective and bone tissue prior to implant placement, researchers are investigating the quality and quantity of the bone matrix and the physiological stages of bone generation and resorption to improve the bone-implant interface. Our research included nine dental implant failures, without prosthetic supra-structures, immediately loaded or loaded after osseointegration. The analyzed samples were from the BIOMAT Research Center, Politehnica University of Bucharest, Romania, and experienced different modalities of surface preparation. Comparative analysis of the tissue at the bone-implant interface was investigated by scanning electron microscopy.
