A dental technologist (dental laboratory technician) is a member of the dental team who, upon prescription from a dental clinician, constructs custom made restorative and dental appliances.〔(Dental Council of New Zealand, ''Notice of Scopes of Practice and Prescribed Qualifications'' )〕〔(General Dental Council UK, ''Scopes of Practice'' )〕 There are four major disciplines within dental technology. These are ''fixed prosthesis'' including crowns, bridges and implants; ''removable prosthesis'', including dentures and removable partial dentures; ''maxillofacial prosthesis'', including ocular prosthesis and craniofacial prosthesis; and ''orthodontics and auxiliaries'', including orthodontic appliances and mouthguards.〔(''Dental technician/dental technologist'' NHS Careers )〕 The dentist communicates with the dental technologist with prescriptions, drawings and measurements taken from the patient. The most important aspect of this is a dental impression into which the technologist flows a gypsum dental stone to create a replica of the patients anatomy known as a dental cast. A technologist can then use this cast for the construction of custom appliances.〔(''Fabricating Casts'' http://www.tpub.com/content/medical/14275/css/14275_203.htm )〕〔(Crown and Bridge Restorations, http://www.qualitydentistry.com/dental/restorative/candb.html )〕 ==Fixed Restorations== A fixed dental restoration is an appliance designed to replace a tooth or teeth that may have been lost or damaged by injury, caries or other oral diseases. These restorations are distinguished from other restorations by the fact that once they have been placed by a dentist the patient can not remove them.〔(''The functional fixed'' http://www.scribd.com/doc/6630184/The-Functionally-Fixed-Restoration )〕 Such Restorations include; crowns, bridges, veneers, fixed implant restorations, inlays and onlays.〔(''Types of Dental Restorations'' http://www.mercurypoisoned.com/different.html )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dental technician」の詳細全文を読む スポンサード リンク
