The drive for all-ceramic or metal-free dentistry has had its ups and downs over the past decade. However, computer-aided design/computer-aided manufacturing (CAD/ CAM) materials have been introduced into the marketplace for the fabrication of single-unit restorations and 3and 4-unit bridges. These materials hold promise for predictably satisfying the need for esthetic and strong restorations f...

A variety of therapeutic modalities, from implants to conventional Maryland bridges, can be used for the replacement of a traumatically missing anterior tooth. The reinforcement of composite resins by fibers improves their fracture toughness and resistance. Fiber-reinforced composite (FRC) bridges can be a good alternative to conventional prosthetic techniques. The purpose of this article was t...

Growing demand of invisible braces byesthetically conscious patients has led to remarkable inventions in materials for esthetic labial archwires. Archwires with excellent optical clarity and mechanical properties comparable to conventional archwires have been manufactured by almost all the leading companies of orthodontic products in the past two decades, but their clinical use is still limited...

Rehabilitation of patients with disabilities of head and neck region, due to either congenital or acquired defects is a challenging task. These defects range from minor cosmetic discrepancies to major functional limitation. The prosthodontics management of these patients should aim at not only restoring the functional and esthetic handicap, but also ensure psychological well being. For facial r...

re-establishing a patient’s lost dental esthetic appearance is one of the most important topics for contemporary dentistry. new treatment materials and methods have been coming on the scene, day by day, in order to achieve such an aim. most dentists prefer more conservative and aesthetic approaches, such as direct and indirect laminate veneer restorations, instead of full-ceramic crowns for ant...

Congenital missing of mandibular permanent incisors with retained primary incisors may jeopardize the esthetic appearance and psychological development of children, especially during the years of transition into adolescence. The retained primary teeth are necessary for the maintenance and normal development of alveolar bone, which in turn is essential for future definitive rehabilitation. In su...

A series of 8 new complexes of titanium and zirconium with diamido ligands bearing an ethylene and propylene bridge between the two amido groups were synthesized and tested for ethylene polymerization. Titanium complexes bearing an ethylene bridge between the two amido groups showed higher activities than the derivatives with a propylene bridge. In the case of the zirconium complexes, the p...
