Embodiment

[0032] Such as figure 1 As shown, the method for making a digital tooth preparation and implant combined surgical guide of the present invention includes the following steps: S1: scan the patient's oral cavity to obtain a preoperative model including the oral cavity situation, and obtain the DICOM data of the patient's oral cavity by shooting CBCT; S2: according to the The above preoperative model determines the target restoration according to the actual restoration principle, and obtains the final wax-up data of the target restoration; S3: After the target restoration is reduced in equal thickness, it is refined and smoothed to form a virtual tooth; The preoperative model, the DICOM data and the wax-type data are fitted, the implant system and the implant model are selected according to the information of the bone and the information of the wax-type teeth, and the implant is determined in the preoperative model, the DICOM data and the three-dimensional position in the wax-up ...

Abstract

The invention discloses a manufacturing method of a digitalized tooth preparation and implanting combined operation guide plate. The manufacturing method comprises the steps that a preoperative modelincluding oral cavity conditions is obtained, and data is acquired; a target repairing body is determined and wax type data is obtained; after equal-thickness shrinking is conducted on the target repairing body, fine finishing and smoothing treatment are conducted to form a virtual tooth body; the three-dimensional position of an implant in the preoperative model, the data and the wax type data isdetermined; an operation guide ring model is corrected; extending is conducted to obtain an operation guide plate model; printing forming is conducted on the combined operation guide plate model through 3D printing. The invention further discloses the operation guide plate. According to the method, the operation guide plate is designed by using a digitalized design technology and a 3D printing technology, in the modeling process, tooth body preparation operation design, implanting operation design, implanting base station mould obtaining and prepared base tooth mould obtaining are completed simultaneously, clinical operation steps and the treatment frequency are reduced, and the corresponding material cost and time cost are reduced.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for making a digital tooth preparation and implant combined surgical guide and the surgical guide. Background technique [0002] Fixed restoration is currently one of the most important restoration methods for patients with tooth defects. The technology of crown and bridge veneer included in fixed restoration has a history of more than 100 years. Regardless of the fixed restoration method, tooth preparation surgery is required to bond the restoration to the prepared abutment teeth to complete the fixed restoration. . [0003] As one of the most commonly used restoration methods for tooth loss and dentition loss, implant restoration is widely used and accepted by doctors and patients because of its good comfort, high chewing efficiency, and good aesthetics. Over the past 50 years of implant restoration, the technology has become more and more mature. [0004] With the...
