OVERDENTURES

Overdentures can reduce shrinkage of the jawbone and redirect forces and pressure in the mouth, helping the dentures stay stable. 

For patients with dental-related conditions, such as cleft palate, oligodontia, cleidocranial dysostosis and Class III occlusion, overdentures may be especially useful.

In general, overdentures provide improved function and retention when compared to conventional dentures, which may become unstable over time or require refitting.

Advantages - Include preservation of alveolar bone, proprioception, enhanced stability and retention and maintenance of vertical dimension of occlusion. It is also useful for patients with congenital defects such as oligodontia, cleft palate and Class III occlusion. It can be easily converted to complete denture over a period of time. 

Disadvantages - Include that meticulous oral hygiene is pertinent in order to prevent caries and periodontal disease. It tends to be bulkier and overcontoured Encroachment of interocclusal distance. This treatment modality is an expensive approach with frequent recall check-ups of the patient than a conventional removable complete denture.
