Purpose. In prosthdontic treatment, application of fixed bridge to the expanded intermediate tooth loss often causes overloading of the abutment teeth.<BR>Removable bridge with saddle was considered to reduce this danger of over loading.<BR>However, little is known about the degree of the reduction by the tissue support of the saddle.<BR>The purpose of this study was to evaluate the reduction of occlusal force concentration to the abutments by applying the tooth-bound saddle.<BR>Methods. The subject was the same as in the first report.<BR>Measurement was carried out on the canine and second molar.<BR>Each retainer was constructed with a telescopic crown.<BR>Two types of removable bridge were assessed with or without tooth-bound saddles.<BR>Test occlusal force of 60 N was applied to the center of bridges.<BR>Occlusal force distribution to the abutments and to the bound saddle was measured simultaneously.<BR>Conclusion. Support by the bound saddle on an alveolar crest was observed by giving saddle, and the decrease of occlusal force distribution to the abutment teeth was observed.
