 # For a loose complete denture relining and rebasing can be done in which of the following condition:

A. Excessive alveolar bone loss 

B. When centric relation and centric occlusion do not coincide 

C. The patient is poor and cannot afford new dentures

D. More than 2 mm loss of alveolar bone height 

The correct answer is C.  The patient is poor and cannot afford new dentures.

Relining and rebasing Indications:

• Immediate dentures at 3 - 6 months after their original construction. 

• When the residual alveolar ridges have resorbed and the adaptation of the denture basis to the ridges is poor. 

• When patient cannot afford the cost of new dentures. 

• Geriatric or chronically ill patients 

• Centric occlusion should coincide with centric relation 

Contraindications: 

• Excessive amount of resorption 

• Abused soft tissues are present 

• Patient complains of temporomandibular joint problems 

• Dentures have poor esthetics 

• Dentures creating speech problems 

• Severe osseus undercuts exist, until surgical removal and healing occur.
