This Concept Map, created with IHMC CmapTools, has information related to: PONTIC CLASSIFICATION - JD's part, disadvantages expensive, Composite resin Improved post-curing process, leakage at metal-resin interface due to continuous dimensional change of veneers, Spheroidal although cleansable, pontic is concave archway mesiodistally creates free passage of food particles, All-Metal Pontics used when patient has parafunctional habits, PONTIC CLASSIFICATION Depending on Mucosal Contact with Mucosal Contact, Ovate in terms of Contraindications, advantages low plaque-retaining capacity, Contraindications when patient is unwilling for surgery, the concavity is created either through surgically at some later time, Acrylic Resin-veneered restoration Advantages do not require high-melting range alloys, dimensional change from water absorption and thermal fluctuations due to high surface area of a thin resin veneer, PONTIC CLASSIFICATION Based on material used All-Metal Pontics, Based Metal Alloys advantages higher percent elongation, triangular shaped spaces around the tissue contact have a tendency to collect debris, Modified Ridge Lap in terms of Tissue-contacting area, Acrylic Resin-veneered restoration Disadvantages leakage at metal-resin interface, set into a concavity in the ridge wherein the concavity is created, Ridge Lap Disadvantages
