Implant Supported Overdenture

Edentulism refers to complete absence of teeth and is considered a disability by the World Health Organization. The reasons for edentulism are many. Loss of teeth has several negative consequences. It is associated with deterioration of orofacial tissues. Treatment options for complete edentulous patient can be fixed and removable. Implant-supported overdentures represent a significant advancement in prosthodontic treatment, offering improved stability, function, and patient satisfaction compared to conventional complete dentures. This approach involves the use of dental implants to anchor a removable denture, enhancing retention, stability and reducing movement during mastication and speech. The overdenture can be supported by two or more implants and retained by using various attachment systems such as bars, locators, or ball attachments. Clinical outcomes demonstrate higher success rates, improved oral health-related quality of life, and better preservation of alveolar bone. This dissertation discusses about the treatment options, planning considerations, selection criteria and maintenance requirements for various attachments systems used in implants.
