This Concept Map, created with IHMC CmapTools, has information related to: PONTIC CLASSIFICATION - KHADS COPY, with a porcelain veneer, it is the most commonly used pontic design in the esthetic zone, for both maxillary and mandibular fixed partial dentures, Metal-ceramic pontics Advantages stronger because porcelain is bonded to the metal substrate rather than cemented to it., Excessive thickness of porcelain which is often true in the cervical portion of a pontic, Sanitary Advantage easier plaque control, Acrylic Resin-veneered restoration Advantages do not require high-melting range alloys, Modified Ridge Lap in terms of Ridge Contact, Spheroidal aka Bullet-shaped, Sanitary Features Space beneath the pontic - 2mm, Metal-ceramic pontics Requirements ensure uniform thickness of porcelain, long span bridges which are more susceptible to mechanical problems, Metal-ceramic pontics Disadvantages Excessive thickness of porcelain, post-curing process advantage over enamel low wear rate, Resin-veneered Pontics new-generation developing veneering material Composite resin, Aluminous porcelain pontic cannot be used if there is insufficient space, resistance to abarasion lower than enamel or porcelain, Characteristics it is easily flossed, the contour of the tissue-contacting area of the pontic should be convex, whenever possible even if a small amount of soft tissue on the ridge must be surgically removed to facilitate it., Faciolingual Surface may have a slight concavity on the facial side of the ridge, when hygienic pontic design is used since both are used for teeth in the nonappearance zone, Composite resin Improved post-curing process
