Problems solved by technology

[0003] At present, there are still some problems in the position design of implants in clinical practice: 1. Usually, clinicians make preoperative planning subjectively based on professional knowledge and bone mass conditions of patients; There is no reference boundary for the lingual distance; 3. In the design process, there are not only manual errors of the operator, but also measurement errors due to the two-dimensional perspective of the measurement plane

Embodiment 1

[0030] In this embodiment, an design method for utilizing manual intelligence techniques for the location of the implantation region is provided, including the following steps:

[0031] Step 1, the establishment of standard crown

[0032] According to the "gypsum teeth engraving training tutorial", the constant dental anatomy described in "Oral Anatomy" (the crown length, the crown, the crown, the low-distance label, the neighbor long axis, neck high mark The engraving parameters such as the line, the crown length marking line are designed, and the standard three-dimensional form of 28 constant teeth that can be omitted;

[0033] Step 2, the construction of the standard dentition form

[0034] (1) Build a parabolic line form

[0035] The vertical distance between the maximumwise between the left and right sides of the lip side and the left and right side of the dentition is referred to as the vertical distance between the leading weights of the dentition, and the two-side second c...

Embodiment 2

[0061] Based on the first embodiment, the difference in the present embodiment is in that step 2, using Bonwill-hawley tooth archographic map to construct a tooth parabolic form, specifically: six ahead width and not only determine the front part The radius and arc length of the arc, and the equipments of the waist triangle it constructed also determined the direction of the line segments of the rear portion, and finally, the line segment of the second and third grinding teeth is returned to the midline turning; first X, Y coordinate The axis, according to the AC = (both sides of the front tooth width and + 3 mm) / 2 to make points A, C. Since HC = HA = AC, ∠CHA = 60. With H as a center (coordinate (O, an AC)), a circular arc having an AC as a radius, a circular angle range of 30 ° to 150 °, and then the A point is round, a radius of 57.15 mm, a circular angle range The arc of 180 ° ~ 360 °, the curve is the basic map of the individual's teeth (Bonwill-Hawiey).

Embodiment 3

[0063] Based on the first embodiment, the difference in the present embodiment is that in step 4, the method of establishing a personalized tooth column is: the gradation value (light and dark) compares to find the endo boundaries of the inner and outer side boundaries in the osteogenesis, the minimum of the matrix OR The multiplier, multiple identification points fitted to form a tooth arch.

Abstract

The invention discloses a design method for an implant position in an edentulous area by utilizing an artificial intelligence technology. The design method comprises the following steps: step 1, establishing a standard dental crown; step 2, constructing a standard dentition form; step 3, acquiring anatomical information of a patient and identifying a personalized dentition; step 4, determining the future dental crown position of the tooth missing area; and step 5, obtaining the central axis of the dental crown, namely the future ideal implant axis position. According to the method, the influence of factors such as measurement errors and subjective assume on preoperative implantation is avoided, and the scientificity, accuracy and feasibility of preoperative design are guaranteed; and the optimal posture of the position and angle of the implant is automatically presented in a three-dimensional space, the design of an implantation scheme is more intuitively displayed, clinical doctor-patient communication is facilitated, meanwhile, the clinical working time of doctors is saved, and the working efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of oral medical technology, and more particularly to a design method for use with artificial intelligence techniques for the position of the missing region. Background technique [0002] Planting the correct tooth correctly restore the shape and function of teeth, with good solids, support and stability, is beneficial to the mouth, hard tissue health, durable, reach harmonious, beautiful appearance. The number and size of the dental implant is related to the design of the type and support of the upper structure of the denture. The design of the implant position is the basic conditions for assessing the success of the plant. According to the principle of planting plan according to the repair plan, the implantation design of the implant in the cultivation of denture repair should consider the following: to prevent damage nerve, the bottom end of the implant from the mandibular nerve The upper edge of the tube wall, t...
