What is an overdenture?- By Dr Amir Mostofi DDS, Dip. MSc

An overdenture is a cheaper removable substitute for a full jaw fixed implant treatment. A denture with one or more teeth, prepared roots, or implants covered at the base is known as an overdenture. Any removable dental prosthesis known as an overdenture is one that covers and rests on one or more natural teeth that are still present, their roots, and/or dental implants. Overdentures can be implant- or conventionally tooth-supported. Alveolar bone is found to be preserved and the process of total edentulism is postponed. For senior individuals who have lost some teeth but not all, making them qualified for a set of full dentures, an overdenture is typically employed. The overdenture is detachable and not fixed in the mouth. Overdentures have the advantage over complete dentures in that the roots that are still in the maxilla (upper jaw) or mandible (lower jaw) protect the top or lower jaw's bone, reducing bone resorption.

Implants may support an upper or lower overdenture. The most frequent number of implants used to stabilise an upper denture is 4, despite the fact that there is little evidence to conclusively demonstrate the appropriate number of implants for stabilising an upper overdenture. Support for a mandibular overdenture was improved when two implants were present rather than just one implant.
The patients could also chew much better and was overall more pleased with the overdenture. Sometimes a metal bar connecting implants will enhance retention of an overdenture. The patient's overall satisfaction with the overdenture increased along with how much better they could chew. Initially chewing abilities are decreased, however when the overdenture has been fitted for a year, the chewing cycle improves.
