Description
Technical Field
The present Disclosure (Disclosure) relates generally to an ARTIFICIAL ALVEOLAR BONE BLOCK (ARTIFICIAL ALVEOLAR BONE BLOCK FOR IMPLANT DRILLING training), and in particular, to an ARTIFICIAL ALVEOLAR BONE BLOCK that can perform IMPLANT DRILLING training with reproducibility.
Background
Here, a background art about the present disclosure is provided, but it does not necessarily represent a known technology (This section development related to the present disclosure while being not limited thereto).
As for the Classification of Bone Density (Bone Density) or Alveolar Bone Density, lekholm & Zarb Classification, misch Bone Density Classification (Misch Bone Density Classification), etc. (Reference and Tec techniques used in Alveolar Bone Classification; JBR Journal of Interdisclinary Medi cine and Dental Science, seriwatacamai D, et a., J Interdisciply Med Dental 2015, 3.
Fig. 1 is a table showing an example of conventional bone density classification, and according to the Lekholm & Zarb classification, the bone density is classified into 4 groups, type 1 indicates a bone composed of homogeneous Cortical bone (Cortical bone), type 2 indicates a bone composed of thick Cortical bone and cancellous bone (Trabecular bone), type 3 indicates a bone composed of thin Cortical bone and dense cancellous bone, and type 4 indicates a bone composed of very thin Cortical bone and low-density cancellous bone. The Misch classification is a perceptual and intuitive classification compared to the Lekholm & Zarb classification, D1 representing the density or stiffness of the oak or maple scale, D2 representing the density or stiffness of the pine or spruce scale, D3 representing the density or stiffness of the balsa scale, and D4 representing the density or stiffness of the Styrofoam scale.
Fig. 2 is a diagram showing an example of the jaw bone classified by Misch, and the anterior maxillary bone 11 mainly has a density or hardness of D3, and occasionally has a density or hardness of D2. The posterior maxillary aspect 12 mainly has a density or hardness of D4, and in the case of Sinus transplantation (Sinus grafting), has a density or hardness of D3. The mandibular anterior 21 has a density or stiffness of D2 primarily and a density or stiffness of D1 to the extent of 25% in the resorbed anterior mandible (resorbed instrument). The posterior mandible 22 has a density or hardness of primarily D3, and occasionally D2. As in the past, when training an implant drill hole using wood blocks divided into 4 groups (D1, D2, D3, D4) and composed of trees, there was a problem in intuitively understanding the actual state of the jawbone or alveolar bone. That is, when drilling a hole in a block having a density or hardness of D2 (for example, a pine block or a spruce block), the density or hardness of D2 mainly corresponds to the mandibular anterior portion 21, but the mandibular posterior portion 22 and a part of the maxillary anterior portion 11 of the jaw bone correspond thereto, and therefore it is difficult for the trainee to match the block to the corresponding part of the jaw bone or the anatomical structure of the alveolar bone. In addition, when drilling a hole in a block (for example, a balsa block) having a density or hardness of D3, the density or hardness of D3 mainly corresponds to the maxillary anterior 11 and the mandibular posterior 22, but a part of the mandibular bone in the maxillary posterior 12 corresponds to this, and thus it is similarly difficult for the trainee to intuitively match the block to the corresponding part of the mandibular bone or the anatomical structure of the alveolar bone. In the case of the Misch classification, the density and hardness of the bone are expressed based on the tree, and it is difficult to maintain consistent characteristics depending on the age of the tree, the dry state of the tree, the part of the tree (the central part or the outer part), and the like, and thus it is difficult to feel the feeling of actually drilling the alveolar bone during training. That is, since it is too finely divided and thus finely divided blocks have no reproducibility or uniformity, it is difficult to train drill holes according to the anatomical structure of alveolar bones in the course of training to feel their density or hardness.

Detailed Description
Fig. 3 and 4 are views for explaining an artificial alveolar bone group according to the present disclosure, the artificial alveolar bone group comprising: a 1 st block 10 having a 1 st hardness range corresponding to the hardness of the mandibular advancement 21; a 2 nd block 20 having a 2 nd hardness range corresponding to the hardness of the lower back 22 and the hardness of the upper front 11 and having a hardness (N; e.g., 65, 50) lower than the hardness (H; e.g., 85, 75) of the 1 st block 10; and a 3 rd block 30 having a 3 rd hardness range corresponding to the hardness of the posterior maxillary aspect 12 and having a hardness (S; having a value lower than the lower limit of the 2 nd hardness range) lower than the hardness (N) of the 2 nd block 20. A set of blocks is made up of 3 blocks (10, 20, 30) in a manner corresponding to the alveolar bone anatomy based on density or hardness. For example, the block is made to be (30 mm × 85mm × 19 mm) in size.
The 1 st block 10 is configured to correspond to the mandibular anterior 21 having the highest hardness in the alveolar bone, the 2 nd block 20 is configured to correspond to the mandibular posterior 22 and the maxillary anterior 11 having intermediate degrees of hardness, and the 3 rd block 30 is configured to have the hardness corresponding to the maxillary posterior 12 having the lowest hardness. With such a configuration, the trainer performs the implant drilling training while matching the position of the actual alveolar bone with the density or hardness corresponding thereto.
Preferably, the block set is made of synthetic resin. The hardness of the alveolar bone is stably reproduced by the synthetic resin, and thus a block group having excellent reproducibility unlike a tree can be provided. Further, by using synthetic resin, the color of each block (10, 20, 30) can be made different, and the blocks can be distinguished without requiring a separate mark. The material and the production method are not particularly limited as long as the hardness is the above-mentioned hardness. For example, the synthetic resin is made of polyurethane, and the amounts of additives can be adjusted to vary the hardness (75 hardness synthetic resin: polyurethane (70-75%), soda lime borosilicate glass (10-12%), aluminum hydroxide (15-18%), 50 hardness synthetic resin: polyurethane (80-88%), soda lime borosilicate glass (12-20%)). However, in the case of the 3 rd block 30, in consideration of the hardness range, since the synthetic resin material has such hardness and has a texture similar to that in the case of alveolar bone drilling, and it is difficult to find an appropriate material from the economical viewpoint, it is preferable to combine the synthetic resin and the tree material which have been used conventionally, thereby solving such a problem. For example, the 3 rd block 30 is composed of a body (31. Similarly, the synthetic resin forming the film 32 is made of a polyurethane material, and the hardness can be adjusted by adjusting the additive. The coating film 32 has a higher hardness than the body 31, so that the hardness of the entire 3 rd block 30 can be increased. The coating film or the synthetic resin film 32 may be formed by coating, but may be bonded to the body 31 after film formation. Therefore, this is referred to as a hardness reinforcing film. By the way, the trainee can feel the initial entrance feeling when the drill starts entering the alveolar bone at the time of actually drilling the maxillary posterior 11 of the alveolar bone.
The 1 st hardness range is a range including 85 and 75, and is a range corresponding to the hardness of the mandibular anterior region 21. The 2 nd hardness range is a range including 65 and 50, and is a range corresponding to the hardness of the mandibular posterior 22 and the hardness of the maxillary anterior 11. The 3 rd hardness range is a range corresponding to the hardness of the maxillary posterior aspect 12, and may have a value smaller than the lower limit of the 2 nd hardness range (in the case of a soft material such as balsa wood, it is difficult to express the hardness by a specific value), and the hardness value is a value to which a Shore D type durometer is applied. As the hardness reinforcing film, various materials used for surface coating for protecting the material, such as a urethane material coating, a UV coating, a paint, and a protective solution (rose), can be used.
Next, various embodiments of the present disclosure will be described.
(1) An artificial alveolar bone block set for drilling training of a hole for an implant, comprising: a 1 st block having a 1 st hardness range corresponding to the hardness of the lower jaw front; a 2 nd block having a hardness range of 2 nd hardness corresponding to the hardness of the lower jaw rear part and the hardness of the upper jaw front part, and having a hardness lower than that of the 1 st block; and a 3 rd block having a 3 rd hardness range corresponding to the posterior maxillary hardness and having a hardness lower than that of the 2 nd block. Here, when the 3 rd block is configured to have a multilayer structure, the hardness represents an average hardness.
(2) In the artificial alveolar bone group, the 1 st hardness range includes hardness 75. As a result of the test, dentists prefer hardness 75 over 85.
(3) In the artificial alveolar bone group, the 2 nd hardness range includes a hardness of 50. As a result of the test, the dentist prefers a hardness of 50 over a hardness of 65.
(4) In the artificial alveolar bone group, the 3 rd block is provided with a hardness reinforcing film at a side into which the drill is inserted.
(5) An artificial alveolar bone block set for drilling training of a hole for an implant, comprising: a 1 st block having a 1 st hardness range corresponding to the hardness of the lower jaw front side, and having the same density and hardness; a 2 nd block having a 2 nd hardness range corresponding to the hardness of the lower jaw rear part and the hardness of the upper jaw front part, having a hardness lower than that of the 1 st block, and having the same density and hardness; and a 3 rd block having a 3 rd hardness range corresponding to the posterior maxillary hardness and having a hardness lower than that of the 2 nd block. Here, it should be understood by those skilled in the art that the identity (identity) of density and hardness means the identity of density and hardness in the case of manufacturing synthetic resin in general.
(6) In the artificial alveolar bone group, the 1 st and 2 nd blocks are made of synthetic resin. The 3 rd block may be made of synthetic resin.
(7) In the artificial alveolar bone group, at least a part of each of the 1 st, 2 nd and 3 rd blocks is made of a synthetic resin.
(8) In the artificial alveolar bone group, the 3 rd block includes a tree material.
(9) In the artificial alveolar bone block set, the 3 rd block is combined with a hardness reinforcing film in a main body made of a tree material.
According to the artificial alveolar bone block set of the present disclosure, implant drilling training conforming to the anatomical structure of an actual alveolar bone can be performed.
According to another artificial alveolar bone group according to the present disclosure, an artificial alveolar bone group having uniform hardness may be provided.
