All surfaces contacted by the denture base.

Area in the mouth used to support a denture against functional forces during chewing.

Areas of the mouth that need to be relieved from the denture base to prevent discomfort or irritation.

Full mouth dentures without natural teeth.

Part of the denture that contacts the supporting areas in the mouth.

Forces perpendicular to the chewing surface generated during chewing.

Loss of bone tissue due to pressure.

Reduced blood flow to tissues.

A procedure to record the shape and structure of the oral cavity using special materials and trays.

A technique for taking dental impressions that applies pressure only where needed, avoiding damage to soft tissue.

Wax used in custom impression trays to reduce pressure on soft tissues during an impression.

Areas of the oral cavity that can withstand pressure during an impression or denture fabrication, including teeth and hard palate.

A type of oral mucosa, present on the roof of the mouth and the gum ridge, that is tough and resistant to wear and tear.

A type of oral mucosa, found in the cheeks, lips, and floor of the mouth, that is soft and delicate.

The hard outer layer of bone, present in most areas of the mouth except the ridge of the gums.

The soft, inner layer of bone, present along the ridge of the gums, that is more prone to resorption.

Areas in the mouth that can withstand the forces of chewing and provide stable support for dentures.

Tough, protective tissue lining the mouth that helps dentures stay in place.

Areas of the mouth that provide resistance to chewing forces, helping hold dentures in place.

Edges of the denture base that are determined by tissues like frenums (muscle attachments) or the vestibule (space between teeth and cheeks).

Areas in the mouth that need to be left free of denture pressure to prevent discomfort or irritation.

A small, raised bump of tissue behind the front teeth, which needs to be relieved on the denture to avoid pressure.

A ridge of tissue in the roof of the mouth that extends from the front to the back, needing denture relief.

A bony bump above the canine tooth, providing support for dentures.

1. Cortical bone: Strong, dense bone that provides resistance to forces.
2. Keratinized, attached mucosa: Tough, resistant tissue that helps hold the denture in place.
3. Perpendicular to occlusal forces: Able to withstand chewing forces directly.

Limiting structures act as boundaries, determining the limits of denture base extension. They prevent the denture from covering areas that are sensitive or prone to irritation.

Relief areas are areas in the mouth that are exempt from direct denture base pressure during rest and function. This prevents discomfort, irritation, and potential damage to sensitive tissues.

The space between the cheek and the teeth/denture

A small, crescent-shaped indentation on the posterior border of the palate, which limits denture base extension.

A fibrous band that extends from the pterygoid hamulus to the retromolar pad, dividing the buccal and lingual vestibules.

Two small bony projections on the lingual surface of the mandible, just below the lower incisors.

A bony shelf located in the lateral part of the alveolar ridge, supporting the denture base.

A fold of tissue that attaches the tongue to the floor of the mouth.

The space between the tongue and the inner surface of the teeth.

Two prominent bony ridges on the lingual surface of the mandible, extending from the symphysis to the molar area.

A surgical procedure to reshape the alveolar ridge, removing bony irregularities or sharp edges to improve denture fit and stability.
