DENTURE BASE MATERIALS By ASMAA GAMAL GROUP 02 MIU 2016 / 2017
WHAT IS A DENTURE BASE ? Its that part of a denture which rests on the oral mucosa and to which teeth are attached, to provide for comfort, aesthetic, and fundamentally accurate functions mostly in retention and efficiency.
IDEALISTIC FEATURES
Accuracy of adaptation A. PROPERTIES 01 02 03 04 07 05 06 Density Thermal conductivity Strength, oral cleanliness Low cost Potential future relining as close as possible B. FUNCTION The masticatory function by supportingthe artificial teeth and effecting the transferof occlusal forces. Biocompatibility ~
Metal - AcrylicAcrylicMetal TYPES OF DENTURE BASE MATERIALS
Based on the indicated case, denture base selection will vary greatly depending on the advantages and the disadvantages of each material. B. SensitivityA. Weight and bulk For instance :
METAL DENTURE BASE INDICATIONS ADVANTAGES DISADVANTAGES 1. All clinical non- aesthetics situations 2. Deep bite cases 3. Condensed inter maxillary spaces where a thick base cannot be used. 4. Acrylic allergy 1. Good biocompatibility, 2. Good mechanical properties. 3. Proper transmission of sense of taste and heat, providing a natural feel for the patients. 1. Patients allergic to metal <rare> 2. Lack of proper extension in buccal shelf area. 3. AESTHETICS
ACRYLIC DENTURE BASE The acrylic resin material is considered an aesthetic denture base and is preferable to patients mainly for of its natural appearance.
Distal extension cases where relining is required frequently Patients allergic to metal. Inadequate mechanical properties Poor thermal conductivity Low impact strength Can only be used as temporary Replacement in most cases. Irritant Ease of repair and manipulation Adequate strength Low cost Light weight Satisfactory color. INDICATIONS DISADVANTAGES ADVANTAGES
INDICATIONS 1. Aesthetics 2. Strength CONTRA-INDICATIONS 1. When relining is necessary
