Dental model 100 for implant surgery, regenerative surgery and surgical technique training according to an embodiment of the present invention, as shown in Figures 1 to 5, the mainframe 110 is provided similar to the oral form of a person ), The alveolar bone unit 120 provided on the upper side of the main frame 110, the periosteum unit 130 provided on the upper side of the alveolar bone unit 120, and the gingival unit provided on the upper side of the periosteum unit 130 ( 140 and a plurality of teeth 152 are implanted in the alveolar bone 120 and then the teeth 150 provided to be exposed to the surface of the gingiva 140, and the dimensions provided inside the teeth 150 160.

The mainframe 110 is formed similar to the oral form of a person, and is configured such that the maxillary body 112 and the mandibular body 114 are connected to each other via the connecting piece 116.

The maxillary body 112 is configured to form the upper jaw of the main frame 110 and the palate is formed to be covered with a certain thickness by the gingiva 140 forming the gum.

That is, the gingiva 140 covering the palate of the maxillary body 112 is relatively different from other parts ie, the gingiva 140 covering the main frame 110 so that a part of the gum can be removed and removed during the gum transplantation operation. It is formed thick. At this time, the thickness of the gingiva portion 140 covering the palate of the maxillary body 112 is about 3-4 mm, preferably less than 4 mm.

The maxillary body 112 is formed to be thicker than the gingival portion 140 covering the palate area is different from the gingival portion 140 covering the other portion, so that the experienced person can experience the feeling of the actual gum transplant surgery.

That is, the experienced person may have an experience of removing and removing a portion 140a of the gingiva 140 from the palate site of the maxillary body 112 during the gum transplantation operation and transferring it to the gum transplantation site.

At this time, the palate of the maxillary body 112 is formed in a negative direction after the driving direction of the large palatal artery 112a is formed in color so as to be excised to avoid the driving direction of the artery during gum transplantation.

Gum transplant surgery is a surgery to cut and transplant a part of the palate of the maxillary body 112 in a region without gum.

The mandibular body 114 is a configuration which forms the lower jaw of the main frame 110.

The connecting piece 116 is configured to be provided at one side of the main frame 110 so as to interconnect the maxillary body 112 and the mandibular body 114. The connecting piece 116 serves to open or close the maxillary body 112 and the mandibular body 114.

The alveolar bone 120 is formed of hard tissue so that the tooth 152 can be implanted, and a plurality of alveolar bone defects 122 are provided, and the actual placement of the tooth 152 is felt on the upper side of the main frame 110. It is formed to give a bone density of D1-D4 to reproduce. At this time, D1 ~ D4 is disposed to be mixed with each other in the alveolar bone 120.

Where D1 is a dense sebaceous bone that provides a bone density with the feel of oak or maple, D2 provides a dense, dense or porous sebaceous bone and a bone density with a coarse bone shovel inside, and D3 is thin. It is to provide a bone density having a porous cortical bone and fine bone within the bone, D4 is to provide a bone density having a feeling of styrofoam into the bone formed micro bone.

In other words, D1 means the hardest alveolar bone to provide the optimal conditions when implant placement, D4 means the weakest alveolar bone.

Therefore, the experienced person can experience various implantation feelings similar to the actual person according to the bone density (D1 ~ D4) of the alveolar bone 120 when the implant is placed on the dental model 100.

The plurality of alveolar bone defects 122 is configured to reproduce the defect site formed according to the loss of the alveolar bone, and is formed such that a plurality of alveolar bone defects are disposed at any position of the alveolar bone 120. At this time, the defect is formed by reducing the volume to reproduce the normal absorption of the alveolar bone.

That is, when the alveolar bone is removed from the tooth 152, the alveolar bone is recessed much more than the missing volume of the tooth 152, and the alveolar bone defect 122 is smaller than the volume of the missing tooth 152 to reflect this. To form larger (the volume of the defect is larger than the volume of the missing tooth).

By providing such alveolar bone defects 122 largely, the experienced person can practice more efficiently during implant placement.

In addition, according to the formation of the alveolar bone defect 122, the experienced person can experience bone induction regeneration or alveolar bone graft surgery when the implant is placed on the site where the alveolar bone is severely lost.

That is, if the alveolar bone defect 122 is found when the implant is placed in the alveolar bone 120, the implant implantation condition is lacking, and then the bone induction regeneration or alveolar bone graft surgery is performed on the alveolar bone defect 122 before the implant is implanted. Done.

Here, guided bone regeneration is performed by forming a space using a barrier membrane at the gingival area irrespective of the periodontal tissue and inducing osteoblast regeneration into the alveolar bone defect 122 at the bottom of the space. It is a technique to plan. That is, to prevent bone formation in a condition sufficient to place the teeth 152 is to prevent the bone formation to induce bone tissue regeneration.

The bone guided regeneration was developed from guided tissue regeneration, and the biological and biomechanical factors for bone guided regeneration are applied to the principles of periodontal tissue induced regeneration. For successful osteoinduction, valve repair is essential, and periosteal flap surgery is required.

Alveolar bone grafts can be removed from themselves (autologous bone grafts), removed from others (allografts), or obtained or synthesized (as bone derivatives) on the gum and jaw bones that are missing due to cleft lip and palate. It is a surgery to insert bones, and the implanted bone fragments are naturally absorbed as new bones are made, and bones removed from oneself are known to have the best results.

Common bones used for such alveolar bone grafts include sciatic (hip bone), skull, ribs (ribs), and the sciatic bone is used a lot.

Here, the implant surgery for the dental model 100 of the present embodiment is widely carried out by those skilled in the art before the application of the present invention, a detailed description thereof will be omitted.

The periosteum 130 is formed of a soft tissue on the upper side of the alveolar bone 120 and is formed through a double injection with the gingiva 140 described later by a silicon material. At this time, the periosteum 130 is formed such that the surface hardness of the silicon is greater than the silicon surface hardness of the gingiva 140 to be described later to be similar to the anatomical structure of the oral cavity of a real person. That is, the silicon surface hardness of the periosteum 130 is about 50 ~ 70, preferably less than 70 is formed. In addition, the periosteum 130 has a thickness of 0.5 to 1 mm.

The periosteum 130 may be visually confirmed that the periosteum is cut during periosteal relaxation in the various incisions through periosteal treatment, and at the same time, the periosteum is elongated when sutured after the incision is formed to have a large silicon surface hardness. It is possible to reproduce the feeling of a real person being pulled. In this case, when the periosteal loosening of the periosteum 130 is performed, the inner surface of the periosteum 130 is cut into a groove shape, and accordingly, a minimum tension is applied in the suture direction when suture is performed after implantation or implant placement for the dental model 100. Can be pulled through.

In addition, the periosteum 130 is formed of a silicon material having a surface hardness similar to the anatomical structure of the oral cavity of a real person, so that the feeling of an actual incision or suture can be kept as it is when experiencing various procedures.

Here, Periosteal Releasing Incision, even if the incision was designed with primary suture in mind, is difficult to obtain primary union, such as an increase in volume due to transplantation or implant implantation immediately after extraction due to unforeseen circumstances. This will be done when it occurs. This is to take advantage of the elasticity of the plastic connective tissue above the periosteum. Usually, the incision is made deeper into the periosteum, and each incision can be pulled about 2 mm in the crown direction. Periosteal incisions are usually made more than once, note that this incision should always be placed on the mucosa, and to the gingival 140, it is of no use because there is no elasticity in this part. In addition, care should be taken not to break the valve. In addition, the valve should be sufficiently moved in the crown direction only if the incision is continued to an average depth of 1 mm from the mesial to the centrifugal valve. Here, the crown direction refers to the head portion of the tooth 152 that is placed in the alveolar bone.

The gingiva portion 140 is formed of a soft tissue on the upper side of the periosteum portion 130 and is formed of a silicon material. At this time, the gingiva 140 is formed such that the silicon surface hardness is smaller than the silicon surface hardness of the periosteum 130 so as to be similar to the anatomical structure of the oral cavity of a real person. That is, the silicon surface hardness of the gingiva portion 140 is about 15 to 20, preferably less than 20 is formed.

The gingiva 140 is formed of a silicon material having a surface hardness similar to the anatomical structure of the oral cavity of a real person, so that the feeling of incision or suture may be preserved as it is during various dental surgery.

The tooth part 150 is formed such that a plurality of teeth 152 are placed in the alveolar bone part 120 and then exposed to the surface of the gingiva 140 and a plurality of tooth defect parts 154 are provided.

The plurality of tooth defects 154 is configured to reproduce the defects formed in accordance with the loss of the teeth and are formed at arbitrary positions between the teeth.

The tooth defect part 154 is formed to reproduce the defective part of the real person's tooth 152, and thus the experienced person may experience the actual implant placement feeling by directly performing the implant on the defective part of the tooth 152. It becomes possible.

The dimension part 160 is configured to be provided inside the tooth part 150 and is formed to have the same distribution of nerves and blood vessels similar to the anatomical structure of the oral cavity of a real person.

The dimension 160 is formed to reproduce the anatomical structure of the actual human oral cavity as it is, so the experienced person during the procedure such as implant placement, bone induction regeneration, alveolar bone graft surgery for the dental model 100, 160 You can practice to prevent damage to nerves and blood vessels.

As described above, the dental model 100 for training the implant surgery, regenerative surgery and surgical technique according to an embodiment of the present invention, unlike the prior art using the pig jaw as a training means for various techniques of dentistry, Implantation, bone guide regeneration, alveolar bone graft, periosteal loosening, gum transplantation, incision, suture, etc. It is possible to improve the educational effect while learning it.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have. Therefore, such modifications or variations are not to be understood individually from the technical spirit or point of view of the present invention, the modified embodiments will belong to the claims of the present invention.
