{Mobile Tutorial system of Tooth Carving}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a carving exercise system using a mobile device (i.e., a personal terminal), more particularly, a virtual wax model is displayed on a mobile device, The virtual tooth wax model, which is the result of the virtual practice, is compared with the practice setting tooth, and the practitioner uses the actual wax model to measure the actual The actual tooth wax model, which is a result of actual exercise, is imaged by a mobile device, and the mobile device is used to compare and evaluate actual tooth wax models and practice setting teeth, The present invention relates to an exercise system.

In order to understand the tooth form and learn the basic skills of the clinic, the learner who has entered the field of dentistry needs a tooth carving practice. Especially, the tooth carving practice is more effective when a step - by - step model can be observed whenever necessary.

There is a need for a 3D tooth modeling virtual tooth, a virtual tooth wax model, and a tooth carving exercise system that enables tooth carving using a virtual touch pen.

In addition, in the case of only practicing practitioner alone, it is impossible to know whether practicing is performed properly, and evaluation of the result of the virtual practice or actual practice is desired.

Generally, it is common for a person to replace a tooth that he or she used when growing up with an adulthood tooth, so that it can be divided into a teat (tooth) and a ganny (permanent tooth). Teething begins at 6 to 7 months after birth and consists of 20 teeth, 10 in each of the upper and lower teeth. Ganni (Yongguchi) is in the spot where the tooth was removed from around 6 years old. Me and permanent teeth are completed, including 32 teeth, including 16 wisdom teeth, including wisdom teeth.

In addition, the teeth are divided into crown, tooth, root, and root point. Clinical classification includes crown, cervical, root, and root attachment. Teeth are hard, except for the dental contents in the center. Most of the teeth consist of dentin (dentin), and enamel, a very hard mineral, usually covers the crown over gingiva. The thin cementum covers the root portion embedded in the jaw, where the crusta petrosa is the true bone. The dental cavity is composed of two parts, a water chamber and a water pipe. The water chamber is mostly in the crown, and the water pipe penetrates the inside of the root to reach the root apex. Even if a tooth has two or more roots, there is at least one tube or canal in each root. There is a dimension in the pulp cavity, which is soft tissue including connective tissue, blood vessels and nerves.

As shown in Fig. 1, Ganji (permanent tooth) has a central incisor (1), a lateral incisor (2), a canine (3), a first premolar (4) The second premolar (5), the first molar (6), the second molar (7), and the third molar (8) The first premolar teeth 4, the second premolars 5, the first molars 6, the second molars 7, the third molars 8, and the molars 1, 2, 3, Is called the posterior portion.

The anterior teeth (front teeth) refer to six teeth from the center to the left and right canines. The middle teeth are called the central teeth (1), the lateral teeth on the side are called the lateral teeth (2), and the teeth next to the lateral teeth (3).

The premolars 4 and 5 are two behind the left and right canines 3 and are called first premolars 4 and second premolars 5 in order.

The first molar, the second molar (7), the third molar (8 wisdom teeth) (8), and the third molar ).

Also, teeth have 4 or 5 faces, and the name of each tooth (tooth face) is called differently depending on the direction in which the tooth faces.

In terms related to the direction in which the tooth surface is directed, each direction of the teeth is divided into the tooth surface side and the root side with reference to the long axis of teeth, and the cutting side 24, the occlusal side 20, the tooth side 23, (21) and the distal side (22) based on the teeth or the teeth.

In the protruding part of the crown (the head part of the tooth), the cusp is a protruding enamel like bulge in the posterior occlusal plane and lingual side and a tip of cusp is sharp in the cut part of the canine And the mamelon is a protrusion formed on the cutting of the incisor. The cingulum is a protrusion formed on the tooth 13 of the frontal lingual surface. The marginal ridge is the occlusal surface of the anterior teeth, The lingual ridge is a ridge formed from the peak of the canine to the cervical spine. The cusp ridge is a ridge formed in the mouth of the canine, And a triangular ridge is a ridge formed in a triangular shape toward the center of the occlusal surface at the mouth of the molar and a transverse ridge is a ridge formed by a lingual triangular ridge and a lingual triangular ridge Is attached, facing in line form Union ridge, ridge four weeks (obilique ridge) is a union ridge is triangular ridge buccal and lingual triangular ridge is connected to the opposing diagonal.

At the depression of the crown, the groove is a line depression between the lobes and leaves, the cusp and cusp, ridges and ridges, and the triangular groove is formed between the triangular ridge and the rim The fossa is an irregular circular or triangular wide depression on the tooth surface and the fit is the deepest depression on the tooth and the intercuspital space is the cranial cusp It is a wide depression formed between the lingual cusps.

In the root region, the root canal is the dimension in the root and the apical foramen is the hole in the apical region where the nerve and blood vessels enter. The accessory canal is mainly the root apical The lateral canal is the lateral branch of the main canal from the area other than the root apex and the root furcation is the area where the root of the multicentric root is cleaved .
