Classification of Overdentures

Classification of Overdentures for Implants are:
1. Bar overdenture
2. O-ring overdenture

Common complication for bar overdenture is clip fracture. While in O-ring overdenture is rubber ring damage.

A bulky denture can develop from the bar and clip in Bar overdenture. It is not indicated for insufficient occlusal clearance.

O-ring has simple clinical and manufacturing procedure. It is not indicated if the insertion angle between the implants is completely out of the line.
