Mechanical Dentistry

Mechanical qualification of collagen membranes used in dentistry.

AIM The aim of this work is the qualification of commercially available collagen membranes in a comparative manner. The natural origin of collagen makes standardization difficult. Nevertheless, through dimensional and mechanical measures it is possible to mechanically qualify collagen membranes, and compare them. METHODS Three commercially available collagen membranes used in Guided Bone Rege...

Application of Zirconia in Dentistry: Biological, Mechanical and Optical Considerations

With the aim of replacing the infrastructure of metallic dental prostheses, structural ceramics have been improved and have become increasingly more popular in dentistry. Among the dental ceramics, zirconia has emerged as a versatile and promising material because of its biological, mechanical and optical properties, which has certainly accelerated its routine use in CAD/CAM technology for diff...

Cosmetic dentistry is still dentistry.

Multi-purpose materials in dentistry - is it possible to match maximum mechanical and biological properties/performance?

In this issue of the Journal of Applied Oral Science, two interesting studies raise an intriguing question: is it possible to match great mechanical and biological properties in multipurpose materials used in dentistry? In the first study, Caldeira, et al. 1 (2013) investigate the antimicrobial and fluoride release ability of orthodontic bonding materials. Obviously, an efficient bonding is the...

Conservative Dentistry

ummary: Intermittent methohexitone for conservative dentistry has been shown to cause clinically undetectable respiratory obstruction, depression of the laryngeal reflex, and arterial hypoxaemia. Because of the pronounced decrease in total peripheral resistance, the blood pressure was maintained only by large increases in cardiac output. Furthermore, the output of the heart could not increase w...
