Problems solved by technology

[0003] The existing guide plate technology is obviously not suitable for personalized implants, especially some special-purpose dental implants. At the same time, the existing design methods are not personalized enough, resulting in low positioning accuracy of the guide plate, which can easily cause implant holes. dislocation

Embodiment 1

[0015] Embodiment 1, the preparation method of personalized hole preparation guide plate, comprises the following steps:

[0016] 1) scanning the dental implant affected area by a CT scanner, the dental implant affected area includes the edentulous place and adjacent teeth, and obtains the surface morphology parameters of the labial side, lingual side and tooth socket side of the alveolar bone at the edentulous place, and Surface morphology parameters of adjacent teeth;

[0017] 2) According to the surface morphology parameters obtained in step 1, use the Mimics software to reconstruct the model of the affected area of ​​the implant three-dimensionally, and then use the Magics software to select the alveolar bone positioning segment area and the adjacent tooth positioning segment that need to be covered by the guide plate on the surface of the affected area model of the dental implant The area of ​​the positioning section of the adjacent tooth covers the 120° inner arc area of...

Abstract

The invention provides a method for producing a personalized pre-perforated guide plate. The method comprises the following steps: 1) scanning an implantation affected area, and obtaining the surfaceform parameters of the alveolar bone of a missing tooth and its adjacent teeth; 2) reconstructing an implantation affected area model in a three-dimensional manner, selecting the alveolar bone positioning segment area and adjacent tooth positioning segment areas, which need to be covered with a guide plate, on the surface of the implantation affected area model, and performing stretching to obtaina guide plate model; 3) intruding a dental implant model into the alveolar bone part in order to be overlapped with the guide plate model, and carrying out stretching removal on the overlapping areaon the guide plate model to form through holes in order to obtain a surgical guide plate model; and 4) carrying out integrated 3D printing on the surgical guide plate model by an SML technology. The using position is determined according to the distribution conditions of the alveolar bone of the implanted area of a patient, and the adjacent teeth thereof, and pre-perforation is carried out to finally complete the personalized design and manufacturing, so the fit degree of the guide plate and a human body is high, thereby the positioning function is improved.

Description

technical field [0001] The invention relates to the technical field of dental implantation, in particular to a preparation method of a personalized hole preparation guide plate. Background technique [0002] At present, traditional standard dental implants need to prepare holes before implant surgery. Generally, professional doctors need to determine the position and angle of drilling based on CT images and surgical experience. In order to improve the accuracy of surgical drilling, a surgical guide plate is used to assist drilling, which determines the specific position and angle of the drilling with reference to the adjacent teeth in the implanted area. [0003] The existing guide plate technology is obviously not suitable for personalized implants, especially some special-purpose dental implants. At the same time, the existing design methods are not personalized enough, resulting in low positioning accuracy of the guide plate, which can easily cause implant holes. disloca...
