Abstract:
Objective: To study the implant-bone interface remodelin g after loading of submerged and nonsubmerged implant denture.Methods: 8 adult beagle dogs were used to build the animal model. Submerged and nons ubmerged implants were implanted into the bilateral mandible. Fixed metal full c rown was used to carry out the submerged and nonsubmerged implant denture. The b eagle dogs were sacrificed by steps after loading of the dentures. HE staining t echnique was used to observe the dynamic remodeling process of implant-bone int erface.Results:2 weeks after loading of implant denture, a major ity of the implant surface attached to bone tissue directly, however, at the int erface, especially at the top of the screw thread, bone tissues were absorbed an d substituted by fibrous tissues. 4 weeks after loading, fine attachment was fou nd at the implant-bone interface and the previouly observed fibrous tissue at t he interface was gradually remodeled to form new bone. 8 weeks after loading, i mplant directly attached to bone tissues by osteo-interface, and the cellular c omponents and capillaries were decreased at the interface.12 weeks after loading , all implants attached to bone tissues by osteo-interface with high combinatio n level, typical Havers system was observed at the interface.No obvious differen ce in the interface remodeling was observed between the submerged and nonsubmerg ed implant denture. Conclusion:There is no distinct difference i n the implant-bone interface remodeling after the loading of submerged and nons ubmerged implant denture.
