Embodiment 1

[0031] Such as Image 6 , 7 As shown, the dental implant surgery guide plate for full dentition is in contact with the alveolar bone or mucous membrane to locate the base body 5 at the surgical site. The base body 5 is provided with at least one guide hole 51 for drilling, and each guide The hole 51 corresponds to the corresponding implant socket on the alveolar bone; the base body 5 is provided with a positioning hole 52, and the positioning hole 52 cooperates with the positioning nail 4 arranged in the patient's oral cavity; the guide plate platform 53 is used as a positioning surface for controlling the drilling of the drill bit depth. The positioning pin 4 is fixed in the patient's oral cavity as a positioning reference. When the positioning pin 4 is inserted into the positioning hole 52 of the base 5, the position of the base 5 can be locked to prevent the base 5 from drifting, so that patients with complete dentition can also use it The guide plate is used for dental i...

Embodiment 2

[0035] The method for making the dental implant guide plate with complete tooth loss includes the following steps:

[0036] 1) Preliminarily determine the position of the positioning pin 4 on the patient's gum bed, and fix the positioning pin 4 on the corresponding position of the gum 3; the method of fixing the positioning pin 4 on the gum 3 is to implant the positioning pin 4 into the patient's alveolar bone ; The positioning nail 4 is fixed on the patient's gums 3 as Figure 5 shown;

[0037] 2) Take a CT scan of the patient's oral cavity, and determine the implantation plan based on the CT data. The content of the implantation plan includes the number of implants, the type of implants, and the distribution of implants; The number of holes to be prepared on the patient's alveolar bone, the distribution position of the implants corresponds to the distribution of the prepared holes on the alveolar bone, and the type of implant corresponds to the shape and depth of the prepar...

Abstract

The invention relates to a whole-tooth lost dental implantation guide plate, which includes a matrix that contacts an alveolar bone or a mucosa to position an operation site. The matrix is provided with at least one guide hole for drilling. Each guide hole corresponds to a corresponding implantation hole on the alveolar bone, and is equipped with a positioning plane for controlling the prepared hole depth. The matrix is provided with positioning holes, which cooperate with positioning nails disposed in the mouth of a patient. The positioning nails are inserted into the positioning holes to fix the matrix position. The method for making the whole-tooth lost dental implantation guide plate comprises: fixing the positioning nails at the corresponding positions on a gum; determining an implantation scheme according to CT data; making a plaster model of the patient gum equipped with the positioning nails or an intraoral scanning model; combining the implantation scheme designed according to the CT data and the plaster three-dimensional model or the intraoral scanning model to generate a guide plate model; and making the guide plate according to the guide plate model. The guide plate provided by the invention has the advantages of less trauma to patients and accurate positioning.

Description

technical field [0001] The invention relates to an implantation guide plate used in dental implantation and a manufacturing method thereof, in particular to a dental implantation guide plate with complete tooth loss and a manufacturing method thereof. Background technique [0002] Dental implants are becoming more and more popular among the options for the restoration of missing teeth. The placement accuracy of the implant directly affects the position accuracy of the final implant. In order to obtain the ideal restoration effect, it is necessary to use the implant guide to ensure the position, angle and depth of the implant. Foreign countries adopt computer-aided design and manufacturing technology, that is, reconstruct the three-dimensional model of the jawbone from the patient's maxillofacial CT image before the dental implant surgery, select the appropriate implant type according to the image data of the jawbone, and combine the teeth and bone volume of the implant, etc....
