INCREASE IN RETENTION OF THE TOTAL REMOVABLE MANDIBULAR PROSTHESIS: ROLE OF THE RHEIN 83 ATTACHMENT

The complete mandibular prosthesis is a challenge for the practitioner and the unfavourable anatomophysiological factors, including the small bearing surface and the importance of resorption often compromises prosthetic retention. The use of root stumps is also a reliable alternative leading to a better prosthetic integration by increasing retention, if the total prosthesis is connected to these root stumps via axial ball or bar connection attachments. In addition, this prosthetic alternative considerably improves the patient's masticatory coefficient and their comfort during the performance of their oral functions, provided that the imperatives of root conservation as well as clinical and laboratory techniques are respected. We propose to illustrate by means of a clinical case where we used the Rhein 83 attachment .
