Problems solved by technology

[0005] The disadvantages of the above method are: 1) When pre-placing the implant guide tube in the edentulous position of the plaster model only based on the doctor's experience, there is no reference to the internal environment of the alveolar bone in the edentulous area of ​​the patient, which often forms a comparison with the actual optimal position of the implant. Large gap; 2) T

Embodiment Construction

[0039] Below in conjunction with embodiment the present invention is described in further detail, please refer to Figure 1 ~ Figure 4 .

[0040] 1) Make a base with positioning beads

[0041] After obtaining the upper and lower jaw silicone impressions of the patient's oral cavity, cast a plaster model 1 on the silicone impressions, and after the plaster is cured, remove the mold for trimming; Platform 3 2 mm above gum line 2, see figure 2 .

[0042] The base is made of self-gel material, and the shape of the missing teeth is simulated on the platform 3 of the missing teeth; with the simulated stacked teeth as the center, three adjacent teeth are extended forward and backward, on the surface and gums Evenly cover the self-gel with a thickness of 1.5 mm; after the self-gel is solidified, remove it upward along the gum to obtain a base, and correct the base. The base is used for taking oral CT.

[0043] Along the lingual or palatal and labial or buccal surfaces of the bas...

Abstract

The invention discloses a method for preparing a positioning guide plate of oral and dental implants. The method comprises the following steps of 1) preparing a base plate with a ball plunger; 2) carrying out computerized tomography (CT) on an oral cavity with the base plate; 3) scanning to obtain model data; 4) building an oral cavity CT three-dimensional model; 5) debugging a threshold; 6) registering the model; 7) virtually implanting; 8) generating a navigation plate; and 9) preparing the positioning guide plate. By adopting the method, the factors such as bone density and blood vessels around the to-be-planted position of an alveolar socket of a sufferer are used to the maximal extent; and the accuracy of the dental implants is improved, so as to improve the survival rate of the dental implants. An implant model is guided into the registered three-dimensional model image to carry out virtual implanting, so that the implant efficiency of the dental implants is improved favorably; and the clinical operation time of a doctor and the clinic time of a patient are shortened.

Description

technical field [0001] The invention relates to a manufacturing method of a device used for tooth restoration, more precisely, relates to a manufacturing method of a dental implant positioning guide plate. Background technique [0002] Dental implants have obvious advantages over traditional methods of restoring missing teeth, and are gradually accepted by the majority of patients with missing teeth. However, conventional dental implant surgery is mostly based on the clinical experience of dentists, coupled with the individual differences of patients, resulting in huge surgical risks. [0003] The key to dental implant technology is to correctly choose the spatial position of the dental implant. Therefore, before planting, it is necessary to have a clear and intuitive understanding of the surrounding environment of the alveolar bone of the implant, such as: the amount and shape of the patient's alveolar bone, the spatial position of the alveolar nerve and blood vessels,...
