Description

[0001] The present invention relates to a dental information providing method, a dental information providing system, and a computer readable recording medium,

The present invention relates to a dental information providing method, a system therefor, and a computer-readable recording medium therefor. More particularly, the present invention relates to a dental information measuring method and a dental information measuring method, The present invention relates to a system and a computer readable recording medium for the system.

For modern people, the appearance, especially the impression, acts as a criterion for judging people in interviews such as employment or entrance, and also has a great influence on interpersonal relationships such as conversation with others. The shape and balance of jaws are not correct If the teeth are maloccluded, it can affect the appearance and the impression, which can be a factor for hindering the social life. Also, since the chewing action can not be smoothly performed when the food is consumed, the diseases in the oral cavity or digestive system are caused .

In order to solve these problems, orthodontic treatment to improve the oral structure or to improve the face line by applying an orthodontic force to teeth or jaws, and jaw surgery to apply surgical operation to jaws are popular.

The orthodontic treatment corrects various skeletal incompatibilities that may occur during the growth process, corrects the dentition, enables the teeth to perform their normal function, contributes to healthy oral tissues, further enhances the face line, You can create an image.

In addition, the jaw surgery is being popularized as an operation method for improving the malocclusion (malocclusion) of the lower teeth or improving the facial skeletal structure, and correcting the abnormality of the facial skeleton itself by surgery, Is also attracting public attention as a molding method for making the glass. That is, the jaw surgery is also referred to as orthognathic surgery or maxillofacial surgery, and refers to a surgery that corrects such variations in shape and size when the maxilla and / or mandible deviate from normal and have excess, insufficient, or asymmetric growth conditions.

Specific examples of the above jaw surgery include a case where it is difficult to chew, bite or swallow food, an abnormal pronunciation, a chronic pain in the vicinity of the jaw, a case in which the teeth are abnormally worn out, If you can not eat food with the front teeth, you can not reach the front teeth, you can not reach your molars, you have asymmetry on your face (your face is skewed), you have a face damaged by an accident, If you have difficulty closing your lips, and so on.

The jaw surgery generally causes a change in the position of the jawbone through cutting, movement and recombination of the jawbone, thereby forming a more beautiful facial line and improving malocclusion. The jaw surgery is classified into a maxillary operation for operating the upper jaw and a mandible operation for operating the lower jaw. In the case of a patient having the malocclusion, the jaw surgery and the orthodontic treatment are performed together.

Examples of the jaw surgery, particularly mandibular surgery, include SSRO (Sagittal Split Ramus Osteotomy) or IVRO (Intraloral Split Vertical Ramus Osteotomy) The bilateral Sagittal Split Ramus Osteotomy (BSSRO), which is applied to both sides of the mandible,

Here, the IVRO is a mandibular operation method for cutting the ramus vertically, and is mainly used for improving the jawbone. On the other hand, SSRO such as BSSRO is an operation method for sagittal cutting of the superior mandible of both sides, and can be used not only for the sling but also for the improvement of the mandible.

On the other hand, in the medical field, especially in the field of dentistry and plastic surgery, it is necessary to provide consultation / consultation to the physician in advance to show the facial changes after correction or jaw surgery or molding, and also to check the condition of jaws Status), to accurately diagnose and plan a treatment plan.

Recently, the structure of the jaw including teeth is analyzed by analyzing the frontal x-ray image (tomographic radiographic image) and the lateral x-ray image (lateral radiographic image) of the patient's skull. At this time, Sella-Nasion Plane (SN Plane) and Frankfort Horizontal Plane (FH Plane) are used.

The SN plane appears as a line in the analysis of the lateral x-ray image of the skull, which is a plane connecting Sella and Nasion shown in the lateral x-ray image. The Sella is the central point of the Sella Turcica and Nasion is the intersection of the suture line between the nasal bone and the bony bones and the nasal seam line. Central part).

The FH plane also appears as a line in a two-dimensional analysis of the lateral x-ray image of the skull, which is the plane connecting the lowest point of the orbit (Orbitale) and the uppermost point of the ear canal (Porion).

However, since the SN plane is located very far from the maxillary and mandibular complexes in the two types of reference planes described above, the relationship with the jaws is deteriorated and the accuracy of diagnosis is lowered. In the case of the FH plane, It is difficult to set the FH plane as a reference plane to the lateral x-ray image of the skull and there is a possibility of doubt as to the reliability of the diagnosis. When the FH plane is set on the lateral x-ray image of the skull, Experience is very important.

Therefore, the present inventor has developed a dental information providing method and a jaw diagnostic system that present a reference plane that is easy to identify and excellent in reproducibility from a skull image, and presents diagnostic / measurement data for the jaw.
