These tumors are characteristically destructive (Fig. exudate: A material usually resulting from inflammation or necrosis that contains fluid, cells, and/or other debris. These agents are added to graft material or used alone to effect acceleration of healing or regeneration in hard and soft tissue surgical procedures. Missing teeth are mostly replaced on saddles by prefabricated denture teeth made from acrylic, less commonly (historically more frequently) also by prefabricated porcelain teeth. There are several key elements that need to be communicated to the dental laboratory technician to ensure success: preoperative photographs, shade photographs, an accurate full-arch impression of the prepared teeth, a face-bow transfer, a full-arch opposing model, and accurate bite records.
