The area of the mouth that supports a dental prosthesis against functional forces, crucial for stability during chewing.

The available area in the mouth of a patient with missing teeth to support a complete denture during chewing

All surfaces inside the mouth that come into contact with the denture.

The part of a denture that contacts the supporting area in the mouth.

Forces applied perpendicular to the chewing surface of the teeth in complete dentures.

Breakdown of bone tissue due to forces acting on it. Occurs in complete denture use.

Tissue damage due to reduced bloodflow. Possible in the mouth with poor denture fit.

The process of recording the shape and contours of the mouth to create a model for the denture.

Denture support and resistance are maximized when the denture's supporting area is parallel to the occlusal plane, ensuring it can handle chewing forces effectively.

These are areas where denture support should not be placed, as they house sensitive structures, sharp edges, or areas with weak bone.

These are crucial for holding the denture in place, defining the denture's outer edges, and accommodating muscle movements.

The primary support area for maxillary dentures is the flat, hard part of the palate, located towards the back of the mouth.

The primary support area for mandibular dentures is the buccal shelf, a bony area located on the outer cheek side of the lower jaw.

A customized container holding impression material that captures the shape of the mouth for denture fabrication.

Soft wax placed on a preliminary cast to ensure only specific areas of the mouth contact the denture base.

Small holes created in the denture base to reduce pressure on soft tissues.

The strongest parts of the mouth that bear the main forces from denture use. Usually hard bone.

Areas that contribute to denture stability but are not as strong as primary support areas. Usually firmer tissues.

Areas in the mouth that are vulnerable to pressure and should not be touched by the denture base.

The outer perimeter of the denture base where it meets the mouth tissue, ensuring a seal and preventing food from entering.

A customized tray conforms to the shape of the mouth, ensuring only areas capable of resisting pressure are contacted by the denture base, preventing discomfort and tissue damage.
