Problems solved by technology

In the production of temporary crowns, the doctor’s clinical operation is complicated, and because of the characteristics of the resin material, it is impossible to obtain a beautiful and natural effect, and the patient can only bear the inconvenience caused by the temporary crown before receiving the final restoration, which also increases the patient’s time. medical costs

Embodiment 1

[0117] A method and device for digital fixed oral restoration, characterized in that the preparation planning of the preparation is completed before the preparation of the preparation, and the planning is solidified on the cutting guide plate of the preparation, and the cutting guide includes a base of the cutting guide plate of the preparation Support body, at least one axial surface design guideway or / and occlusal surface / incisal surface design guideway, and accessory cutting tool; at least one such cutting guide plate is required to complete the preparation of the preparation; as figure 1 As shown, the specific steps are as follows:

[0118] 1. Obtain a three-dimensional digital model of the patient's occlusion;

[0119] 2. Carry out the digital design of the preparation body on the 3D digital model of the patient's teeth, including the digital design of the axial surface or / and the digital design of the occlusal surface / incisal end, and at the same time perform simulated c...

Embodiment 2

[0204] Such as Figure 12A , Figure 12B As shown, an upper molar is prepared with a preparation cutting guide. Two preparation cutting guides form a set to realize the preparation of the tooth preparation. in Figure 12A The cutting guide includes an axial cutting guide for axial cutting of the lingual and mesioproximal surfaces of teeth; and an occlusal cutting guide for cutting buccal occlusal surfaces. Figure 12B The cutting guide includes an axial cutting guide for axial cutting of the buccal and distal adjacent surfaces of the teeth; and an occlusal cutting guide for cutting the lingual occlusal surface.

[0205] The final axial cutting of the tooth preparation is performed by Figure 12A , Figure 12B Each of the shown guide plates is realized by a cutting guide on the axial surface; the cutting of the occlusal surface is realized by Figure 12A , Figure 12B Each of the occlusal surface cutting guideways shown is realized. The present embodiment adopts the meth...

Embodiment 3

[0262] The difference between embodiment 3 and embodiment 2 is:

[0263] Such as Figure 13A , Figure 13B As shown, an upper molar is prepared with a preparation cutting guide. Two preparation cutting guides form a set to achieve a complete preparation of the tooth preparation. in Figure 13A The cutting guide shown includes one axial cutting guide for buccal, mesial, and lingual axial cutting of teeth; two occlusal cutting guides for buccal and lingual occlusal cutting. Figure 13B The cutting guide shown includes an axial cutting guide that performs distal axial cutting of the tooth.

[0264] The final axial cutting of the tooth preparation is performed by Figure 13A , Figure 13B Each of the shown guide plates is realized by a cutting guide on the axial surface; the cutting of the occlusal surface is realized by Figure 13A The two occlusal surface cutting guides shown are realized.

[0265] The design and preparation method are the same as in Example 2.

Abstract

The invention provides a digital oral fixed restoration method and device. Preparing and planning of a tooth preparation are completed by obtaining a three-dimensional digital model of an oral cavity of a patient before a dentist prepares the tooth preparation, and the tooth preparation is cured on a specially-made cutting guide plate, thereby greatly improving the quality of the tooth preparation prepared by the dentist and improving the efficiency of preparing the tooth preparation prepared by the dentist by the cutting guide plate. Furthermore, the invention can provide a complete set of digital scheme for oral fixed restoration, namely, simulation cutting of the three-dimensional digital model of teeth of the patient is completed in a computer, thereby acquiring a three-dimensional digital model of the tooth preparation of the patient; the oral fixed restoration body can be directly and digitally designed and manufactured on the basis. By virtue of the digital oral fixed restoration method and device, the tooth preparation cutting guide plate of the patient and the restoration body can be delivered to the dentist and the patient together; the patient can directly wear the individually designed and manufactured restoration body during accurate preparing of the tooth preparation; the efficiency and the effect of oral fixation can be greatly improved.

Description

technical field [0001] The invention is applied in the field of dental restoration, and in particular relates to systems, methods and processes related to oral fixed restoration. Background technique [0002] Oral fixed restoration is an important form of repairing a single tooth or dentition defect, that is, repairing a single tooth partial defect or one or several natural tooth defects in the dentition, and restoring its anatomical shape and physiological function. . The basis and premise of oral fixed restoration is to remove a certain amount of tooth tissue and protect the pulp from damage. It uses a single missing natural tooth as a support, and glues the denture to the defect of the natural tooth through an adhesive, or uses the natural tooth or tooth root at both ends or one end of the gap between the missing teeth as the abutment, and makes a solid on the abutment. The body is connected to the artificial tooth as a whole, and the denture is fixed on the abutment to...
