Milident Dental Laboratory Inc., based in Gatineau, Quebec, is a leading provider of high-quality dental products and services to dental professionals for over 20 years. They are consistently facing with local and international competition that forced them to offer competitive pricing. Over the years, this has become a challenge since most laboratory components are imported to Canada at a very high cost. Thus, to be a striving company, Milident Inc. has decided to manufacture and supply their own dental components. In July 2014, Milident Inc. has purchased an advanced lathe machine that has the capability to micro-machine high precision implant components. Milident, in collaboration with the University of Ottawa, are presently working on optimizing the micro-milling manufacturing process to ensure that there are no machining-based defects in fabricated components. However, it is also imperative to optimize, test, and validate the quality of the fabricated components for their intended usage over the life cycle of the components. In addition to their complex shape, these dental components are less than 10 mm in length and about 1 mm in diameter and as such, mechanical testing and quality validation of tensile, fatigue or impact is impossible under standard testing setups. Therefore, a comprehensive mechanical modeling of the dental components is crucially needed to validate the original dental components design or any design optimization before the fabrication process. Developing a mechanical model of the dental components is critical for Milident to mitigate technical and commercial risks because the company plans to launch production and sale of the dental components by the end of 2015. This venture will make Milident the first Canadian manufacturer of high-precision dental implant components. The project will provide Milident with the critical technical and scientific support to achieve this.

Milident Dental Laboratory Inc.位于魁北克的加蒂诺，是一家为牙科专业人士提供高质量牙科产品和服务的领先供应商，已有20多年的历史。他们一直面临着当地和国际竞争，迫使他们提供有竞争力的价格。多年来，这已经成为一个挑战，因为大多数实验室组件都是以非常高的成本进口到加拿大的。因此，为了成为一家努力奋斗的公司，Milident Inc.已决定生产和供应自己的牙科部件。2014年7月，Milident Inc.购买了一台先进的车床，能够对高精度植入物组件进行微加工。 Milident与渥太华大学合作，目前正致力于优化微铣削制造工艺，以确保在制造的部件中没有基于加工的缺陷。然而，还必须优化、测试和验证制造组件的质量，以满足组件生命周期内的预期用途。除了它们复杂的形状之外，这些牙科部件的长度小于10 mm，直径约为1 mm，因此，在标准测试设置下，拉伸、疲劳或冲击的机械测试和质量验证是不可能的。因此，在制造过程之前，至关重要的是需要对牙科部件进行全面的机械建模，以验证原始牙科部件设计或任何设计优化。 开发牙科部件的机械模型对于Milident减轻技术和商业风险至关重要，因为该公司计划在2015年底前开始生产和销售牙科部件。该合资企业将使Milident成为加拿大第一家高精度牙科种植体组件制造商。该项目将为Milident提供实现这一目标的关键技术和科学支持。
