Adjustments and modifications of dentures

Relining

A process that consists of the anatomical-functional rehabilitation of the intaglios of a complete or partial removable prosthesis. It aims to restore the stability and retention of a prosthesis.

​

Relining can be done directly (in the chair) or indirectly (in the laboratory).

​

Reasons for relining:

• Bone resorption

• Weight loss

• Immediate prosthesis

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Rebasing

A process that consists of completely replacing the base of a prosthesis. It also improves the stability and retention of the prosthesis but it cannot be done indirectly, therefore in the laboratory.

​

Reasons for relining:

• Porosity of the base

• Lack of lip support

• Stained dentures

The benefits of relining and rebasing are:

• Improved stability and comfort of the denture

• Reduced food debris trapped between the denture and the gums

• Better distribution of chewing pressure

• Extended life of the denture
