Attachments In Overdentures

A debilitating dental condition affecting millions of individuals across the globe is complete edentulism. Complete dentures are the most common and widely usedtreatment modality of rehabilitation for edentulism. The maxillary completeremovable prosthesis serves as a better treatment modality to the patient as far asretention, support and stability compared to the mandibular complete removable prosthesis. It was found that attachment systems for mandibular two-implant overdentures undergo wear-related changes leading to a reduction or loss of retention under simulated wear tests. The mechanism of wear that modulates the retentive force and wear features of the different attachment systems remains poorly understood and needs further research. Factors related to the material composition, design, dimensions, and the mode of retention of attachment systems have been implied to influence the retention and wear features of these attachments. However, their precise role remains inconclusive in the current literature.
