A cephalometric study of 17 non-growing dentate Class III subjects treated by bimaxillary surgery was undertaken to assess the results of treatment and to evaluate the correlation between soft and hard tissue change. It was concluded that: (i) the orthognathic profiles achieved were brought about by a combination of maxillary advancement and mandibular setback; (ii) a strong correlation in the ...

The Treacher Collins syndrome is characterized by both soft and hard tissue deficiencies. To reconstruct malar hypoplasia with both soft and hard tissues, we designed a new method using cartilage grafts, Y-V advancement flaps, and Z plasty with tissue expansion.

Metallic biomaterials like stainless steel, Co-based alloy, Ti and its alloys are widely used as artificial hip joints, bone plates and dental implants due to their excellent mechanical properties and endurance. However, there are some surface-originated problems associated with the metallic implants: corrosion and wear in biological environments resulting in ions release and formation of wear ...

Taesik Chae, Heejae Yang, Frank Ko, Tom Troczynski. Materials Engineering Department, University of British Columbia, Vancouver, BC Canada V6T 1Z4 Statement of Purpose: Aging of population increases the need for human organ/tissue repairs. Autografts supply, however, has limitation, and allografts may cause the risk of disease transmission and anti-immunization response. One of the alternatives...

Infrared lasers are ideally suited for the selective and precise removal of carious dental hard tissue while minimizing the healthy tissue loss. Since the initial investigations of Stern[1] over 30 years ago, several unique laser applications have evolved for dentistry, namely laser ablation of dental hard tissue, caries inhibition treatments by localized surface heating, and surface conditioni...

abstract: adequate processing of tissues before histologic slices is necessary for preparation of proper histologic sections in animal studies. fixation is one of the most important and early laboratory stages of tissue processing. amount of penetration time of fixator material, into deep layers and central portions of hard tissues, is important factor for prevention of cell lysis. the purpose ...

congenital vascular lesions occur most often in children. parents of these children take them to maxillofacial surgeons directly or during the treatment of other complications such as infection or jaw bone disorders. various terms now used are unable to describe the pathogenesis and mechanism of the effect of vascular lesions on growth and development of facial bone.  term of hemangioma is used...

the minimal invasive nature of lasers, with quick tissue response and healing has made them a very attractive technology in various fields of dentistry which serves as a tool to create a better result than ever before. the rapid development of lasers and their wavelengths with variety of applications on soft and hard tissues may continue to have major impact on the scope and practice in prosthe...
