This Concept Map, created with IHMC CmapTools, has information related to: pontic material 1, Excessive thickness of porcelain which is often true in the cervical portion of a pontic, High-alumina pontics are at times stronger than conventional porcelains, Prefabricated Porcelain Pontic it is difficult to use, the high alumina ceramic tubing or slotted rod and which the porcelain is fired, Prefabricated Porcelain Pontic it is already obsolete, PONTIC CLASSIFICATION PONTIC CLASSIFICATION: Based on material used Aluminous porcelain pontic, Metal-ceramic pontics Requirements framework must provide a uniform veneer of porcelain (approx. 1.2 mm), waxing the fixed prosthesis to complete anatomic contour and then accurately cut back the wax to a predetermined depth, Aluminous porcelain pontic can be used in cases wherein the retainer has partial coverage, more natural look since its porcelain facing is thicker than in metal-ceramic pontics, occlusal contacts must be placed to avoid the junction including excursive and centric contacts, facing made up of prefabricated porcelain, Prefabricated Porcelain Pontic components backing, PONTIC CLASSIFICATION PONTIC CLASSIFICATION: Based on material used Prefabricated Porcelain Pontic, Metal-ceramic pontics Advantages easier to use because the backing is custom made for a space, ensure uniform thickness of porcelain by waxing the fixed prosthesis to complete anatomic contour, when patient has parafunctional habits like burxism, different kinds of facing are sanitary pontic, different kinds of facing are harmony facing, Prefabricated Porcelain Pontic it is very popular before the advent of metal-ceramic
