Prosthetic rehabilitation of severe Siebert's Class III defect with modified Andrews bridge system.

Prosthetic dentistry involves the replacement of missing and contiguous tissues with artificial substitutes to restore and maintain the oral functions, appearance, and health of the patient. The treatment of edentulous areas with ridge defects poses a challenging task for the dentist. Management of such cases involves a wide range of treatment options comprising mainly of surgical interventions and non surgical techniques such as use of removable, fixed or fixed- removable partial dentures.

Prosthetic rehabilitation of a child with velopharyngeal dysfunction - A case report.

The speech of person is a unique mode of expression for an individual. Alterations or deviation from normal speech leading to nasal and unintelligible speech have enormous effects on the psychological well being of a person as it hampers social interactions. The anatomic or functional anomalies occurring as a result of congenital or traumatic defects leading to velopharyngeal dysfunctions influence the speech by making it completely atypical.

Evaluation of stress changes in the mandible with a fixed functional appliance: a finite element study.

Introduction: The aim of this study was to evaluate the effects of a fixed functional appliance (Forsus Fatigue Resistant Device; 3M Unitek, Monrovia, Calif) on the mandible with 3-dimensional finite element stress analysis.

Methods: A 3-dimensional finite element model of the mandible was constructed from the images generated by cone-beam computed tomography of a patient undergoing fixed orthodontic treatment. The changes were studied with the finite element method, in the form of highest von Mises stress and maximum principal stress regions.
