近年来,由于口腔科材料不断发展与更新,复合树指修复临床应用越来越普及,已部分取代了银汞合金的充填及牙体缺损修复,尤其在前牙美容修复上更是广泛地应用于临床。目前,复合树指中有光固化复合树脂,自凝复会树脂反复合体(玻璃离子与树脂复合体)等几种。在临床操作时均需要经过酸蚀处理,冲洗及干燥等步骤。但目前许多医院还在使用CS16型一类的综合治疗合,还需配上涡轮机,使用带橡皮球的手用气铳,临床操作极为不便。要装备一台先进的综合治疗台费用又较昂贵,尤其是基层或农村医疗单位,目前人多还无条件更新。 我院在面临着市政工程的影响,门诊部不久将要搬迁以及经费等因素,目前也无法大批更新。因此
In recent years, due to the continuous development and updating of stomatological materials, the clinical application of composite tree finger prosthesis has become more and more popular, which has partially replaced the filling of amalgam and restoration of dental defects, especially in the cosmetic restoration of anterior teeth In clinical. At present, the composite tree means that there are several kinds of light-cured composite resins, self-curing composite resin complex (glass ions and resin composite) and so on. In clinical practice are subject to acid etching, washing and drying and other steps. However, many hospitals are still using CS16 type of comprehensive treatment together, but also need to be equipped with turbines, the use of rubber ball with the hand Qi, clinical operation is extremely inconvenient. The cost of equipping an advanced comprehensive treatment unit is more expensive, especially at the grass-roots or rural medical units. At present, most people still have unconditional renewal. Our hospital is facing the impact of municipal engineering, clinics will soon be relocated and funding and other factors, the current can not be a large number of updates. therefore
