This Concept Map, created with IHMC CmapTools, has information related to: final final pontic, Characteristics it is a round-end design, Contraindications when there is residual ridge defects, Spheroidal used in areas where the occlusal of the buccal surface is seen, Sanitary Advantage easier plaque control, no chemical bond between resin and metal framework, Acrylic Resin-veneered restoration Advantages do not require high-melting range alloys, Sanitary indication Nonesthetic zones, Sanitary indication impaired oral hygiene, Aluminous porcelain pontic it is cemented to a cast metal framework, most niocompatible of all pontic material excellent ability to resist plaque accumulation, Characteristics wherein with a porcelain veneer, it is the most commonly used pontic design in the esthetic zone,, Features concave fitting surface, with Mucosal Contact ???? Ovate, Based Metal Alloys must resist thermally induced stress, Acrylic Resin-veneered restoration Disadvantages resistance to abarasion, more natural look since its porcelain facing is thicker than in metal-ceramic pontics, Ovate in terms of Characteristics, leakage at metal-resin interface due to continuous dimensional change of veneers, Acrylic Resin-veneered restoration Disadvantages no chemical bond, Aluminous porcelain pontic cannot be used if there is insufficient space
