Problems solved by technology

At present, the teaching of periodontal surgery in domestic medical colleges is carried out on pig jaws, and the structure of pig jaws and periodontal structures are significantly different from those of humans. Periodontal surgery incisions and surgical procedures are practiced on isolated animal models Compared with the actual clinical situation, the distortion is greater, and no good practice can be obtained in terms of hand feeling, body position, or incision design, which seriously limits the clinical teaching effect of periodontal surgery and suturing techniques
In addition, it is inconvenient to obtain isolated animal models, and the peculiar smell and ugly appearance of the models affect the teaching environment
[0003]The bionic gingival tissue of the existing dental and jaw models is mainly made of silicone rubber, which has poor flexibility and high brittleness, and is easily broken during periodontal surgery. It is also different from human gingival tissue and other property defects
Although the gingival models imported from abroad have good simulation performance, such as the Rijin model, they are expensive and the teaching cost is too high.
[0004]Clinically, the alveolar bone resorption in different regions of the oral cavity is different, and the types of periodontal pockets are different, resulting in individual differences in treatment
Existing periodontal disease models can only present a certain periodontal lesion structure, or can perform a simple gingival incision operation, but they cannot represent the complete structure and perform surgical method design and operation at the same time
The lack of teeth in the highly simulated and systematic periodontal surgery model severely limits the mastery of periodontal surgery techniques by periodontal students and periodontal specialist residents

Embodiment 1

[0027] Such as Figure 1-3 As shown, a periodontal surgery teaching model of the present invention is a complete upper jaw and lower jaw model, and the upper jaw model and the lower jaw model have a good occlusal relationship, including the model base, alveolar bone block 4, gingiva 3 and artificial teeth 2. The model base includes a maxillary base 1 and a mandibular base 1', and the alveolar bone block 4 includes a maxillary alveolar bone block 4A, a mandibular right alveolar bone block 4B and a mandibular left alveolar bone block Block 4C; the front edge of the maxillary base 1 is embedded with a maxillary alveolar bone block 4A, and the maxillary alveolar bone block 4A is a toothless bone block whose surface fits with the bone geometry of the defect area of ​​the maxillary base 1; the maxillary base 1 and the maxillary alveolar bone block 4A are provided with a hole suitable for the artificial tooth 2, that is, the alveolar socket; the gum 3 is closely attached to the upper...

Embodiment 2

[0035] The different designs of different sections of this model can meet the teaching needs of various periodontal surgery procedures:

[0036] Bilateral upper posterior tooth area Bilateral upper posterior tooth area (no alveolar bone block, no bone modification), used for various types of periodontal surgical incisions (including internal oblique incision, external oblique incision, groove incision, right-angle incision, vertical incision, etc.), operation teaching of gingivectomy;

[0037] ② Upper anterior teeth area (simulating alveolar bone hyperplasia, gingival hyperplasia, insufficient passive eruption of teeth), used for operation teaching of crown lengthening surgery;

[0038] ③Bilateral lower posterior tooth area (mixed bone resorption, including II wall bone pockets, III wall bone pockets, furcation lesions, and bone blocks can be replaced), can be used for periodontal flap surgery, bone grafting, and guided tissue Operational teaching of regenerative surgery.

Abstract

The invention discloses a periodontal operation teaching model. The periodontal operation teaching model comprises a model base, an alveolar bone block, gingivae and artificial teeth. The model base comprises an upper jaw base and a lower jaw base. The alveolar bone block comprises an upper jaw alveolar bone block, a lower jaw right side alveolar bone block and a lower jaw left side alveolar bone block. The alveolar bones which have the periodontitis characteristics and the teeth which have the periodontitis characteristics are combined with the artificial gingivae, so that the implementation process of a periodontal operation is simulated to the maximum extent through the teaching model, and meanwhile teaching cost is reduced; the gingivae are made of imported polyurethane rubber, so that the simulation effect is good, the price is relatively low, and the gingivae are suitable for medical colleges and medical institutions; the clinic periodontal lesion structure and the operating hand feeling of the periodontal operation are simulated, the layering sense is good, and practicability is high; the operation body can be replaced, basic skill excise can be repeated, and popularization and application are facilitated.

Description

technical field [0001] The invention belongs to an oral cavity teaching model, and relates to a tooth and jaw model with a periodontal operation teaching function. Background technique [0002] The surgical model is mainly used for theoretical teaching in medical schools and practice operations for interns in medical institutions, and simulation is particularly important. At present, the teaching of periodontal surgery in domestic medical colleges is carried out on pig jaws, and the structure of pig jaws and periodontal structures are significantly different from those of humans. Periodontal surgery incisions and surgical procedures are practiced on isolated animal models Compared with the actual clinical situation, the distortion is greater, and no good practice can be obtained in terms of hand feeling, body position, or incision design, which seriously limits the clinical teaching effect of periodontal surgery and suturing techniques. In addition, the acquisition of isola...
