For edentulous patients, the integrity of the osteomucosal-bearing surface is a significant factor for the balance of the future removable prosthesis. The supporting tissues are influenced by several factors. Physiological bone resorption, senescence, and changes caused by systemic diseases and polypharmacy lead to modifications in these tissues. Similarly, trauma caused by an ill-fitted prosthesis influences the degree of bone resorption and the development of hyperplastic tissue. The etiology of bone resorption is multifactorial and complex, with continuous individual variations that are often unexplained. Although, no study has been able to establish the importance of the different factors in relation to each other, it is often reported that chronic excessive mechanical pressure in relation to occlusal constraints is responsible for the appearance of local resorption’s areas. The aim of this work is to present, through three clinical cases, the various factors involved in the alteration of the osteomucous-bearing surface and eventually, possible therapeutic attitude to deal with.
With senescence, edentulous patients present unfavorable clinical situations following the continued resorption of alveolar bone and the inevitable narrowing of the prosthetic corridor. That's why rehabilitation with removable complete prosthesis presents a difficult challenge for the dentist. In this connection, the use of the piezographic technique, a promising therapeutic approach, makes it possible to better respect the physiology of the elderly patient while ensuring a compromise of retention, prosthesis stability and comfort. The aim of this manuscript is to present the different stages of realizing a removable complete denture resulting from an impression of the bearing surfaces and a piezographic recording of the prosthetic corridor through a clinical case.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
