“In-vitro study on the Removable Partial Denture Framework Adaptation in CAD/CAM and Conventional Techniques”

Abstract

Teeth loss still marked among the hundred health conditions that most affect the world population that leads to functional faliure and social damage with impact on people's quality of life. Edentulism (partial or complete) is an indicator of the oral health of a population. It may also be a reflection of the success of various preventive and treatment modalities put in place by the health care delivery system.

Removable partial dentures (RPDs) represent asignificant proportion of prostheses used in patients over 65 years of age in developed countries. There are countries where one-third up to one-half of the elderly population uses such prostheses. It is anticipated that the need for RPDs will increase in the coming years. Partial denture is indicated in cases where long-span edentulous area, no abutment tooth posterior to the edentulous space, reduced periodontal support for remaining teeth and need for cross-arch stabilization.

Although various materials and techniques were developed in the dental field, the conventional metallic removable partial denture manufactured by lost wax technique is still used. This old technique is successful however it's inherited drawbacks.
