ENSENAT RODRIGUEZ, Andrés et al. Design and manufacture of a retention bar for auricular prosthesis. Rev. Odont. Mex [online]. 2006, vol.10, n.1, pp.42-48. ISSN 1870-199X.  https://doi.org/10.22201/fo.1870199xp.2006.10.1.15934.

One of the most frequent problems, in order to achieve satisfactory results in auricular prosthetics, is its long-term retention. Until now, adhesives have been the primary means of retention for this type of prosthesis. With the successful development of osseous integrated implants, many treatments for the craniofacial region are now available in order to avoid placement and retention prosthesis difficulties, as well as the treatment acceptance by the patient. Today, it is possible to offer all patients a functional prosthesis, higher aesthetics and a major retention. The aim of this study was to design and manufacture auricular prosthesis in order to replace the conventional chemical retention (adhesives) by a mechanical device, for which a free nickel and beryllium metal was selected (Remanium 2000). This alloy was used to elaborate the retention bar, as well as some castable current polymers used for intraoral prosthesis. Three clinical cases were presented from patients attending Maxillofacial Prosthetic Clinics of the School of Dentistry, University of Campeche. All of the three patients presented congenital anomalies in the auricular pavilion and were candidates for prosthesis retained by implants. The prosthesis placement was successful. Auricular mechanical prostheses consisted in a retainer bar placed on osseointegrated implants. The use of alternative materials reduced the auricular prosthesis comercial costs by 70%.
