This article highlights the feasibility of the additive fabrication of ultra-thin veneers made of lithium disilicate using the lithography-based ceramic manufacturing (LCM) method.
An esthetical appealing restoration of anterior teeth with thin ceramic veneers is considered one of the ultimate challenges in restorative dental prosthetics. These sophisticated restorations can be fabricated in different ways. Both analog and digital subtractive manufacturing processes have been used to date. Either of the methods is highly demanding for the dental technician and dental engineering due to the required low ceramic layer thickness.
Modern additive manufacturing methods, for example LCM technology, enable the production of ultra-thin lithium disilicate veneers with layer thicknesses of down to 0.2 mm and could therefore represent a viable alternative for this indication in the future.
Digital technologies can help streamline workflows, make the outcome more predictable and reproducible, and even further optimize therapeutic restorative options such as highly esthetic veneers for anterior teeth. The reduced material thickness allows for a true non-prep solution or minimally invasive preparation.
本文强调了使用基于光刻的陶瓷制造(LCM)方法增材制造二硅酸锂超薄贴面的可行性。
用薄陶瓷贴面实现美观的前牙修复被认为是口腔修复学中最具挑战性的任务之一。这些复杂的修复体可以通过不同方式制造。迄今为止,模拟和数字减法制造工艺都已被使用。由于所需的低陶瓷层厚度,这两种方法对牙科技师和牙科工程来说要求都很高。
现代增材制造方法,例如LCM技术,能够生产层厚低至0.2毫米的超薄二硅酸锂贴面,因此未来可能成为这一适应症的可行替代方案。
数字技术有助于简化工作流程,使结果更可预测和可重复,甚至进一步优化治疗性修复选项,如用于前牙的高度美观的贴面。材料厚度的减小允许真正的非预备解决方案或微创预备。
