Background and Aim: Considering flexural strength of fiber-reinforced composites (FRC) and also the role of conservative cavities in protecting sound tissue of abutments, the aim of this study was to evaluate the fracture resistance of these bridges by handmade samples in vitro.Materials and Methods: In this experimental in vitro study, 44 sound newly extracted teeth were used to make 22 fixed ...
J. he loss of a permanent anterior tooth on a young patient poses unique problems in replacement for the pedodontic practitioner. Full crown coverage of the abutment teeth necessary for conventional fixed bridgework is often contraindicated due to the large size of the pulp chamber and the potential for pulpal damage. Even if possible, this reduction violates the current concepts of good conser...
The loss of anterior teeth can be hurtful to the patient both psychologically and socially. As the children are becoming more aware these days, they have also become conscious about their looks. Early loss of deciduous anterior teeth has a psychological effect on many children. In such young patients, paper replacement of the teeth can minimize these concerns. Many approaches have been describe...
This clinical case reports the orthodontic treatment of a Class I malocclusion with anterior open bite and bimaxillary dentoalveolar protrusion in a 28-year-old female patient. The treatment of choice was to perform tooth extractions followed by retraction of the anterior teeth, with consequent closure of the anterior open bite and better accommodation of the teeth on their bony bases. This cas...
This project, conducted by the Removable Prosthodontic faculty, compared the mesiodistal widths of the six maxillary anterior teeth with the widths of denture teeth from six different denture tooth manufacturers. Four hundred eighty-eight casts of dental students were measured from the distal aspect of each canine across the facial surfaces of the six anterior teeth with a flexible plastic mill...
OBJECTIVE The aim of this study was to determine the optimal loading conditions for pure intrusion of the six maxillary anterior teeth with miniscrews according to alveolar bone loss. METHODS A three-dimensional finite element model was created for a segment of the six anterior teeth, and the positions of the miniscrews and hooks were varied after setting the alveolar bone loss to 0, 2, or 4 ...
