Modeling of dimensional changes during sintering

Dimensional changes of three-unit implant-supported zirconia frameworks from scanning to sintering

Background and Aims: Passive fitness of implant frameworks are important factors for long-term success of dental implant restorations. The aim of this in vitro study was to evaluate the dimensional changes of implant supported zirconia frameworks fabricated by Zirkonzahn CAD/CAM system during fabrication stages. Materials and Methods: The master model of 3-unit FDP was made of two implant abut...

Advances in Modeling of Microwave Sintering

When traditional sintering techniques are used it is difficult to obtain dense materials with nanometric or submicrometric grain sizes. Microwave sintering was proposed as an alternative technique to overcome the problems of conventional fast heating. However, various problems usually occur when ceramics are sintered by direct microwave heating [1]. Hybrid heating techniques, which combine dire...

Dimensional changes of dental arch following non-extraction orthodontic treatment

Introduction: Since the emergence of normal occlusion concept, selecting an appropriate treatment plan with or without tooth extraction has been a controversial subject. Nowadays, both methods can be successfully used for treatment of patients. However, some clinicians still believe that non-extraction orthodontic treatments have fewer complications. The purpose of this study was to evaluate de...
