Lining

The integration of tooth replacement may lead to signs of incompatibility, infections of the mucous membranes and discomfort. These are rarely real allergic incompatibility reactions. Mechanical stress may lead to pressure sores. The jaw bone may change its form due to reconstructional and deterioration processes. This impairs the accurate fit of the prosthesis. The badly fitting denture base must be adapted to these new jaw conditions by the application of plastics.

Direct lining

Direct lining is performed by the dentist in the mouth of the patient (intraorally). The mixed plastic is applied to the partial or total denture base and left for a few minutes with occlusion and soft part movements. This direct adjustment of a denture base to the prosthetic base takes place via cold-cure or autopolymerisate.

Indirect lining

Direct lining of a denture base takes place in a laboratory. The denture base is moulded in the mouth with the prosthesis, which is coated with casting material. The casting material is usually replaced in the lab by heat curing material. Materials which remain in soft condition are used for particularly sensitive alveolar ridges.
