The greatest strain in distal cantilevered FPDs is recorded mesial to the most distal retainer because most fractures occur in this location. 20 When a distal cantilever bridge is selected, its length is important. UL4 tooth was fractured which was an abutment for mesial cantilever bridge (UL3-pontic, UL4- retainer crown), No caries, minimal coronal tooth structure present Occlusion: Upper arch - Kennedy’s Class 1, Modification 1, considering missing UL3. Historically, attempts were made to overcome this problem by using two abutment teeth. Severe caries occurred by shifted dental prosthesis due to patient’s dental phobia. (See Figures 17, 18 and 19.) By Dr. George Ghidrai. Finally, Roberts13 indicated an acceptable failure rate where anterior three-quarter crowns (retainers) were used in fixed removable and cantilever bridges. But only 73% of the restorations remained free of complications in the medium term. The failure rate of 1.63% a year was lower than the failure rate of all types of anterior retainers at 3.49% a year. Abutment teeth selection. The abutment teeth need long roots and acceptable alveolar support. A cantilever dental bridge is when the “false tooth” is only supported on one side. In2Guide Case Reports : 4Unit Mesial Cantilever Bridge Case. It is the most conservative when one abutment is needed, like in … Cantilever bridge is indicated where the abutment tooth or teeth can carry the occlusal load of the artificial tooth and where the occlusion is protected against potentially damaging rotational forces. upper arch, with a cantilever bridge was contraindicated. After extraction of the existing dental prosthesis and the rest of the root, a temporary crown to be made. Selecting the abutment teeth is one of the most important steps when planning for a dental bridge.Before conducting this step, it is important to determine whether the particular clinical situation is suitable for a dental bridge reconstruction (determining the type of edentulism). Start studying 9 - Conventional Bridgework. The majority of complications were technical, such as chipping or fractures of the porcelain. The result is just as aesthetic but has the benefit that fewer teeth have to be treated. Pre-surgery Condition. A typical example was a bridge to replace an upper canine; two premolar teeth were prepared for three-quarter crown retainers and linked to form a three unit cantilever bridge with a mesial … In partially edentulous patients with mesial or distal cantilevered fixed prostheses, both implant and prosthesis survival rates reached 98% for multi-unit bridges. Lower arch - Kennedy's Class 3, Modification 1 … Learn vocabulary, terms, and more with flashcards, games, and other study tools. To improve the prognosis of the FPD cantilever, the number of abutments should be increased and the number of pontics decreased. If the pier abutment was an implant, I might have also considered placing an attachment on the mesial of the pier abutment dependent upon the mobility of the anterior teeth.
