Comparison of Man Hours Utilized for Mandibluar Overdenture Treatment Retained by Single Implant with Bar Fabricated by CAD-CAM Process and Conventional Casting Processs - An Vivo Study.

ABSTRACT

Introduction: Both the population's average life expectancy and the number of patients without teeth are rising. A 2012 epidemiological survey in India found that 30% of the population is edentulous. The rehabilitation process with a set of removable maxillary and mandibular complete dentures is the standard treatment for patients who are edentulous. This study is the first to incorporate and compare a novel approach to a single implant-retained mandibular overdenture with a bar attachment fabricated by CAD-CAM and a casting process on a single implant in the symphysis region. Method: Five maxillary and mandibular completely edentulous patients were enrolled in the study. Results: Significant difference was seen in the conventional laboratory time and CAD-CAM time as P < 0.05. Conclusion: Compared to the conventional casting process, the single implant-supported bar mandibular overdenture (SISBOD) with a novel bar required fewer man hours and was more convenient.
