This case report demonstrates the full-mouth rehabilitation of a 45-year-old male patient with severe deep-bite by increasing vertical dimension. The technique of anterior maxillary osteotomy performed in the present situation has been found to be effective, requiring anterior and inferior repositioning of the anterior maxilla to provide an esthetic and functional implant supported fixed prosth...

The successful integration of periodontal and restorative dentistry for both natural teeth and implants requires knowledge and application of both mechanical and biological principles. In areas of aesthetic concern, an adequate band of attached gingiva can increase patient comfort, reduce the probability of gingival recession following tooth preparation and simplify restorative procedures. Whil...

This investigation was undertaken to examine the extent to which tooth size and jaw size each contribute to dental crowding. Two groups of dental casts were selected on the basis of dental crowding. One group, consisting of 50 pairs of dental casts (18 males and 32 females), exhibited gross dental crowding. A second group, consisting of 54 pairs of dental casts (24 males and 30 females), exhibi...

primary tooth impaction is a rare finding during the development of primary dentition. several factors contribute to the impaction of a deciduous tooth. this report describes the diagnosis and treatment of a 10-year-old boy who presented an impacted second primary mandibular molar. this tooth, located inferior to the second premolar together with an odontoma, was positioned superior to the prem...

the rehabilitation of heavily abraded occlusion in patients with parafunctional habits is a restorative challenge to the dentist. use of all-ceramic systems in such cases is widely considered, but uncertainty over their resistance hinders their broad use. the authors would like to illustrate a possible approach by mixing two all-ceramic systems based on zirconium dioxide and lithium disilicate....

background bleaching of traumatized discolored teeth is considered an important issue in esthetic dentistry. various methods have been introduced for bleaching, some of which may have adverse effects on soft or hard tissues of the tooth. objectives the objective of the study was to evaluate the effects of ktp laser bleaching on enamel of traumatized teeth. materials and methods a square of 36 m...

As digital dentistry has become widespread and increasingly popular in clinical practice, various attempts have been made to use technologies for dental treatment. Implant surgical guides that these widely used recent implant surgeries. The seating stability of are essential accurately transfer the planned surgery into oral cavity. This case study aimed explore two-step guide system increase a ...

Understanding the contact mechanics of rough tooth surfaces is critical in order to understand phenomena such as surface flash temperature, wear, and gear vibration. In this paper, behavior between meshing beveloid pairs with elliptical asperities focus. The area distribution function asperity was proposed for point curved by transforming elastic problem into an arbitrary radius curvature. addi...
