Implant Overdenture is a denture that is connected to implants placed in the jaws. The purpose is good retention so that patient can function better in eating and speech.

Disadvantages of normal dentures

1 Gradual Bone loss due to pressure on the underlying tissues over time

2 Can be unstable because of tongue movement         

3 Pain of soft tissues caused by the denture

4 Possibility of food and plaque trap and fungal infection if denture hygiene is poor.

Benefit of Overdentures

1 allow attachment to implants through locators that keep denture stable which provides a sense of security

2 maintain bone volume.

3 the denture can be reduced in size because of better retention

4 In cases where dentures cannot be tolerated because of bony protruberances

* A lower overdenture needs two implants but an upper one needs at least four implants as the bone is usually less dense.
