Biomechanics of the Metalloceramic Bridge Prostheses at the Dental Row Lateral Department Small Defect Substitution
A method of mathematical simulation was used for prosthetics improvement of patients with the dental row lateral department small defects by combined bridge prostheses with a support on insets. Four types of the metalloceramic bridge prosthesis constructions were used at a study of a biomechanics in a system of ″bridge prosthesis—supporting teeth—periodontium—alveolar part of a jaw″. The investigation results have demonstrated that a distribution of elastic tensions is unfavorable and can cause complications in bridge prostheses with a mesial support on inset and a distal support in a form of artificial crown.
It is recommended to use the bridge prostheses with a bilateral support on insets in the mesioocclusive and distal cavities and the prosthesis constructions with a mesial support in a form of artificial crown and a distal support in a form of inset for substitution of the dental row lateral department small defects.
