Comparison between Titanium and Composite resin inserts at oral mucosa tissue healing in rabbits

following the insertion of a foreign material beneath a surgically prepared wound : the immune system of the body respond with an inflammatory reaction that is followed by healing if the inserted material was a biocompatible one, in this study we aimed to evaluate the healing process of a surgically prepared wound in lab rabbits oral mucosa following the insertion of different set of biomaterials these were Titanium and Composite resin . using histological examination of the collected samples . the measuring parameters were the inflammatory cells infiltration , granulation tissue formation , reepithelization and two immunohistochemical tests using cluster of differentiation 31 and matrix metalloproteinase 3 expression in the collected samples to Determine the best material that permits for mucosal healing in contact with the examined two types and Measuring any complications that may arise during the healing of the mucosal soft tissue that is in contact with the mentioned materials.
