Abstract

The invention discloses a method for making a digital ceramic powder layered plastic guide plate, which comprises the following steps: obtaining the contour of the outer layer of the restoration; obtaining the contour of the dentin and the developmental leaf of the restoration; Plastic-on-plastic guide plate model; making external porcelain powder-on-plastic guide plate and internal porcelain powder-on-plastic guide plate; filling dentin filler and sintering to form dentin layer single-layer restoration; filling incisal filling and sintering to form dentin layer and incisal modified layered restoration body; filled with transparent fillers and sintered to form an aesthetically layered restoration with dentin layer, incisal finish layer and transparent layer. The invention also discloses a digital porcelain powder layered plastic stacking guide plate. In the present invention, digital technology is used to design the shape of the prosthesis, the shape of the final prosthesis can be predicted before the plastic is piled up, and the delamination effect of the final prosthesis can be predicted, and the dentin and enamel delamination of adjacent teeth can be better imitated, so that Using digital methods to achieve precise aesthetic porcelain powder build-up.

Description

technical field [0001] The invention relates to medical device technology, in particular to a method for making a digital ceramic powder layered plastic guide plate and the guide plate. Background technique [0002] All-ceramic crowns have been widely used in the restoration of anterior teeth aesthetics because of their excellent aesthetic properties. The method of layered plastic porcelain powder can obtain better aesthetic effect, so it is more chosen by patients in clinical practice. In the actual processing process, the base crown is usually made digitally, and then the veneering porcelain part is completed by manual molding. Therefore, different operators, or even the same operator, have different shaping results for the same tooth at different times. [0003] Porcelain powder molding technology is the most important and one of the most difficult technologies in denture production. It not only has great requirements for the technician's clinical experience, but also r...
