Application of endosseous dental implant on restoration of tooth loss / 解放军医学杂志

ABSTRACT

Objective To retrospectively analyze the indication of endosseous dental implant,evaluate the effectiveness of clinical application of endosseous dental implant for tooth loss,and study the possible factors which may affect the success rate of implant denture.Methods One hundred and fifty-seven endosseous dental implants in 94 patients were followed up for 4 months to 8 years.The indications of endosseous dental implant were studied based on the changes in the distribution of dental implants in jawbone.The success rate of osseointegration and restoration of the endosseous dental implant were evaluated by checking the soft tissue around the implants,the stability of the implants,the bone resorption around the implants,and the degree of stability against rotation of the implants.Results The rate of performing endosseous dental implant for restoration of full-mouth anodontia was 7.6%,the rate of endosseous dental implant used in the free end anodontia was 25.5%,and it was 66.9% in non-free end anodontia.The success rate of osseointegration in the endosseous dental implant was 98.1%,and 5 years after prosthesis the success ratio of the endosseous dental implant was 93.8%.The success ratio of the endosseous dental implants which the primary stability(anti-rotation torsion)
