Problems solved by technology

The present invention can determine the position and direction of the implant nail before the operation, but because the corresponding positions of the alveolar bone, blood vessels and nerves cannot be obtained, the guide plate produced is not very targeted, the matching with the alveolar is not good, and it is not easy to maintain long-term stability

Embodiment Construction

[0049] The present invention will be further described below by taking the patient's loss of mandibular second premolars, first molars, and second molars as an example

[0050] step 1:

[0051] 1.1 Carry out a CT scan on the patient's oral cavity, and obtain the CT scan data.

[0052] 1.2 Import CT scan data for 3D reconstruction.

[0053] 1.2.1 Use Materialises interactive medical image control system software (Materialises interactive medical image control system, referred to as Mimics) for 3D reconstruction. Mimics is a set of highly integrated and easy-to-use 3D image generation and editing software, which can input various scanned data (CT, MRI), build 3D models and edit them. After the three-dimensional reconstruction of the oral cavity, its external and internal structures can be observed from any angle. It is an ideal tool for studying the oral structure and has broad application prospects.

[0054] The 3D entity reconstruction method of Mimics software is based on ...

Abstract

The invention relates to a manufacturing method of an implant denture individualized positioning guide plate in the technical field of tooth repair technologies, which comprises the steps of: firstly, establishing a three-dimensional model of anatomical structures of teeth, jaws, maxillary antrums, mandibular nerve conduits and the like according to oral cavity CT data of patients; secondly, carrying out virtual implanting on a solid modeled implant model, matching an implanted model with a patient oral cavity structural data model established after scanning a dental model by using an opticalscanner, determining the position of a guide hole of the positioning guide plate and the shape of a contact surface of gums, inserting a guide pipe in the guide hole; and thirdly, manufacturing a solid positioning guide plate. The solid positioning guide plate can provide optimal implanting position and direction to ensure the safety of an implanting technology and the long-term stability of an implant. The positioning guide plate can maximally utilize the bone quantity of the alveolar bone when in application. The invention can improve the efficiency and the accuracy of the implanting technology, ensure that the implanted implant accords with the biomechanical principle, and guarantee the repair aesthetic effect.

Description

technical field [0001] The invention relates to a manufacturing method of an appliance used in restoration of missing teeth, in particular to a manufacturing method of a positioning guide plate used for planting dentures. Background technique [0002] Dental implant technology is a new technology developed rapidly after the "Osseointegration" theory proposed by Swedish scholar Professor Branemark was recognized in the 1960s. It is a method of replacing missing teeth with artificial implants placed in the alveolar bone. Because it has a very ideal retention and support effect, and it is comfortable and beautiful, and there is no need to grind the adjacent natural teeth, it is favored by patients with missing teeth. [0003] During the whole process of denture implantation, the intraosseous biological positioning of the implant is an important part of the successful implantation. Due to the influence of the three-dimensional irregularities of the upper and lower jaws and the ...
