Dried mandible with shortened dental arch (Kennedy Class 1) was used in the experiment. (1) A high survey line may also result in deformation of the clasp because, on insertion, the clasp is prevented from moving down the tooth by, contact with the occlusal surface. These dimensions should allow the fabrication of occlusal rests that guarantee the necessary oclusal-prosthetic equillibrium (better load distribution, prosthesis stability and oclusal relations) and the required strength against oral cavity loads [3,.
