Abstract

The embodiment of the invention discloses a preparation method of a zirconia all-ceramic implant, comprising the following steps: (a) obtaining CBCT data and surface three-dimensional scanning data ofbones, adjacent teeth and antagonistic teeth in a tooth loss area; (b) registering the acquired CBT data and 3D surface scanning data, and analyzing and determining the overall parameters of the tooth loss area; (c) designing an implant structure based on the overall parameters of the tooth loss area, and cutting the sintered and crystallized zirconia by numerically-controlled ultra-short pulse laser according to the implant structure so as to obtain a zirconia implant; (d) carrying out roughing treatment and polishing treatment on the zirconia implant by numerically-controlled ultra-short pulse laser, followed by cleaning and sterilization to obtain the zirconia all-ceramic implant. By the above method, processing of the sintered zirconia can be realized, and the processing precision ishigh and micro-cracks caused by machining are avoided. In addition, the preparation method has simple process and short preparation time, and the production efficiency is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of stomatology, in particular to a preparation method of a zirconia all-ceramic implant. Background technique [0002] Since the birth of oral implants, titanium metal has been the first choice as the material of implants, which has been widely used clinically and has achieved a very high success rate. However, traditional titanium implants still have their own limitations: on the one hand, the aesthetic effect will be affected due to the shrinkage of the soft tissue around the implant and the risk of exposure of the metal appearance of the implant neck; on the other hand, according to reports in the literature, in Increased concentrations of titanium particles were found in bone tissue and regional lymph nodes close to titanium implants. [0003] Based on the above limitations and the advantages of zirconia materials, scholars at home and abroad began to study the production of zi...
