MOREIRA, André et al. Worn ball attachments: a repair solution without replacement - a case report. Rev Port Estomatol Med Dent Cir Maxilofac [online]. 2020, vol.61, n.1, pp.23-28.  Epub 30-Mar-2020. ISSN 1646-2890.  https://doi.org/10.24873/j.rpemd.2020.07.699.

Tooth-supported overdentures are an excellent solution for increasing the retention and stability of prostheses when compared to conventional removable dentures. However, with long-term use, both the Teflon cap (female part) and the male component of the attachment cemented in the abutment teeth may become worn, and replacement is needed. An 80-yearold female patient visited the department of Oral Rehabilitation of the Faculty of Dental Medicine of the University of Porto with a primary complaint of poor retention of the mandibular overdenture. Clinical examination revealed the presence of two worn ball attachments cemented on the mandibular canines. This clinical case reports a reliable solution for restoring the function of an overdenture with worn ball attachments without replacing the intraradicular post. The Concave Reconstructive Sphere System (Rhein 83R) allowed re-shaping the old ball attachments, reestablishing the overdenture’s retention and Stability.
