Overdenture is any removable dental prosthesis that covers and rests on one or more remaining natural teeth, the roots of natural teeth, and/or dental implants.[1] It is one of the most practical measures used in preventive dentistry. Overdentures can be either tooth supported (conventional / immediate) or implant supported. It is found to help in the preservation of alveolar bone and delay the process of complete edentulism.[2]
Alternative Terminologies
- Overlay Denture
- Hybrid Prosthesis
- Telescoping Denture
- Tooth Supported Denture
- Onlay dentures
- Superimposed dentures
Types
- Tooth supported overdenture
- Implant supported overdenture
Indications
Retention and Stability
- If prescribing a removable prosthesis and there is limited remaining firm teeth in the dentition an overdenture may aid in retention and stability compared to that of a conventional removable prosthesis[3].
Preventative Dentistry
- The use of an overdenture delays the process of leaving the patient completely edentulous and assists in the preservation of bone[3].
- As a main priority for many dentists and patients, preventative dentistry is a reason for prescribing an overdenture as it retains the natural teeth for longer[4].
Patient Anatomy
- Overdentures can be useful for patients with a severe ridge defect or bone resorption[5].
- Patients who have unfavourable tongue positions and muscle attachment for a conventional removable prosthesis could find that an overdenture has increased retention and stability[4].
- If the patient has a superficially placed mental nerve, then the preferential choice of treatment may be to leave certain teeth in place in order to prevent damage to the nerve and prescribe an overdenture for any aesthetic needs[5].
Protection of Root Canal Filling
- An overdenture can be prescribed for a patient who has just had a root canal treatment completed to protect the coronal seal of the tooth if they are waiting to have fixed prosthodontics carried out on the tooth.

Advantages
- Preservation of alveolar bone[6]
- Providing stability and retention
- Improving masticatory efficiency[7]

Research & evidence
A 10 year observational period found that implants which supported overdentures in the mandible had a survival rate ranging from 91.7% to 100%.[8] Furthermore, implant survival rates with respect to their attachment system were found to be best for the ball type attachment which was an average of 95.8 - 97.5%, followed by the bar and magnet ranging from 96.2 - 100% , and 91.7% respectively.[9]
