It has been suggested that for success with immediate loaded dental implants it is necessary that, prior to their placement, bone quantity and quality as well as the biomechanical environment in which the implants are to function be evaluated. However, conventional techniques currently used for immediate implant placement lack sufficient precision and are usually accomplished by opening flap procedures. The purpose of this paper is to report the benefit of sophisticated pre-operative diagnostic implant planning and a flapless surgical approach with immediate loading.
The report describes the use of computed tomography (CT) for three-dimensional (3D) evaluations of bone implant sites, an interactive software program for 3D planning and the fabrication of stereolithographic models as custom surgical templates. The degree of patient satisfaction was evaluated by periodic recall and by adopting a specially designed analogue scale in each visit.
The mean amount of bone loss around the implants was 0.5 +/- 0.1 mm and the satisfactoriness scale was rated high (i.e. 81), at the end of 1 year.
The use of stereolithographic appliances in accordance with flapless surgery makes immediate placement of the implants more predictable.
有人提出，要使即刻负重牙种植成功，在种植体植入前，必须评估骨量、骨质量以及种植体发挥功能的生物力学环境。然而，目前用于即刻种植的传统技术缺乏足够的精确性，通常需通过翻瓣手术来完成。本文旨在报告精密的术前诊断性种植规划和即刻负重的不翻瓣手术方法的益处。
该报告描述了使用计算机断层扫描（CT）对骨种植部位进行三维（3D）评估、使用交互式软件程序进行3D规划以及制作立体光刻模型作为定制手术模板的情况。通过定期回访并在每次就诊时采用专门设计的模拟量表来评估患者的满意度。
在1年结束时，种植体周围的平均骨吸收量为0.5±0.1毫米，满意度量表评分较高（即81分）。
采用不翻瓣手术并使用立体光刻器械可使种植体的即刻植入更具可预测性。
