Abstract

OBJECTIVE: Survival rates of mandibular overdentures on two implants retained by bar-clip system with immediate loading and the factors related to fractures was analyzed.METHODS: Twenty-three subjects were followed for 32 months. Fracture occurrence was the outcome variable, while the thickness of denture base, maxillomandibular space and masticatory efficiency comprised the independent variables.RESULTS: The survival rate was 49.5%, with 34.7% of fractures. There was no association between the independent variables and fractures.CONCLUSION: So, the risk of mandibular overdenture fractures with immediate loading is high. Furthermore, masticatory efficiency, thickness of the denture base and maxillomandibular space did not influence the incidence of fractures.

即刻负荷下颌骨覆盖义齿骨折的生存率及相关因素

目的：分析两种杆夹式种植体即刻加载下颌覆盖义齿的成活率及骨折的相关因素。方法：23名受试者接受为期32个月的随访。骨折发生率是结果变量，义齿基托厚度、上下颌间隙和咀嚼效率是自变量。结果：生存率为49.5%，骨折占34.7%。自变量与骨折之间没有关联。结论：即刻加载下颌覆盖义齿发生骨折的风险较高。此外，咀嚼效率、义齿基托厚度和上下颌间隙对骨折发生率没有影响。

Its abbreviation is Rev Odonto Cienc, which should be used in references, bibliographic legends, and footnotes. The Revista Odonto Ciência is an international scientific journal dedicated to provide a forum for academics, researchers, and practitioners to communicate relevant basic, clinical, education, and epidemiological studies in Dentistry and related fields. The Journal seeks to publish articles on new conceptual models, innovative technology, alternative procedures or treatment to reduce disease burden in the general population or specific groups, thus contributing to translating science into practice and social development. Contributions falling into the following categories will be considered for publication: 1) original research reports of basic and applied oral sciences, epidemiological, and education studies; 2) review article; 3) case report.
