め形成されている歯列保護矯正具に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dentition protection orthodontic tool which has been formed into a shape which can be easily manufactured for a user.
【０００２】[0002]

いはコ字形に形成されている。2. Description of the Related Art In the prior art, a preformed tooth protector, for example, a mouthpiece, has a cross-sectional shape in a direction perpendicular to a dental arch, which is uniformly U-shaped or co-shaped over a molar or anterior tooth. It is formed in the shape of a letter.

位の高さと概ね同一に形成されている。In addition, the thickness of the portion corresponding to the lip surface and the lingual surface is substantially the same as the thickness of the portion corresponding to the occlusal surface, and the height of the portion corresponding to the lip surface is the same as the thickness of the portion corresponding to the lingual surface. The height is almost the same.

欠点がある。When the dentition protector is softened by heating and pressed against a user's dentition or a dentition model, the U-shaped or co-shaped dentition protector is used. When the bottom surface of the character is deformed in accordance with the fissure existing in the occlusal surface of the molar, the wall of the dentition protector corresponding to the buccal surface or the lingual surface is deformed in a direction away from the buccal surface or the lingual surface of the molar. For this reason, there is a disadvantage that it is difficult to secure adhesion to the dentition.

るため違和感が強いという欠点がある。Further, since the thickness of the portions corresponding to the lip side and the tongue side is formed to be substantially the same as the thickness of the portion corresponding to the occlusal surface having a relatively large thickness due to the necessity of shock absorption performance, When a person wears and uses the dental arch, the part corresponding to the lip side or the tongue side presses the lips or tongue, so that there is a drawback that a sense of discomfort is strong.

保護矯正具が歯列弓から脱離しやすいという欠点があ
る。Further, since the height of the portion corresponding to the lingual surface and the height of the portion corresponding to the lip side are formed substantially the same, it is difficult to adhere to the gingival surface on the lingual side when the height is high. In addition, when the tongue has a strong sense of incongruity and the height is low, there is a disadvantage that the orthodontic appliance is easily detached from the dental arch because the area of contact with the gum on the lip side is small.
【０００７】前歯部乃至犬歯部においては、該歯列保護
具と前歯乃至犬歯との間隙が大きいため、歯列への密着
性確保のための加熱軟化成形の操作が繁雑である。In the anterior teeth or the canines, since the gap between the dentition protector and the anterior teeth or the canines is large, the operation of heat softening molding for ensuring the close contact with the dentition is complicated.

着性の確保が容易となる利点がある。[0010] In the case of softening the orthodontic appliance of the present invention and shaping the orthodontic appliance according to the user's dentition or dentition model,
The wall of the dentition protector corresponding to the buccal side surface and the lingual side surface is interlocked with the fact that the portion bent convexly toward the molar occlusal surface is deformed in the direction of flattening by pressing, so that the buccal surface or tongue of the molar teeth Since it is deformed in a direction in which it comes into close contact with the side surface, there is an advantage that it is easy to ensure close contact with the dentition.

利点がある。The cusp of the opposing tooth is fitted into the plane corresponding to the occlusal surface of the opposing tooth at the site corresponding to the occlusal surface of the molar, so that the site is extended in the buccolingual direction and the buccal surface is interlocked. And the wall of the dentition protector corresponding to the tongue side is promoted to be deformed in a direction in which the wall of the dentition is in close contact with the buccal side or the lingual side of the molar. is there.

舌側面に対応する部位の厚さは３．０ｍｍ乃至１．０ｍ
ｍであることが好ましい。Further, since the thickness of the portions corresponding to the lip side and the tongue side is one half to one sixth of the thickness of the portion corresponding to the occlusal surface, the portion corresponding to the occlusal surface absorbs shock. There is an advantage that it is easier to ensure the moldability and adhesion to the dentition and the gingiva at the sites corresponding to the lip side and the lingual side while ensuring a sufficient thickness for the lip. The thickness of the portion corresponding to the occlusal surface is preferably 3.0 mm to 6.0 mm. For example, when the thickness is 6.0 mm, the thickness of the portion corresponding to the lip surface and the lingual surface is 3.0 mm to 1.0 mm. 0m
m is preferable.

Small, while the area corresponding to the labial surface is high, so that it adheres to the gingival mucosal surface of the labial surface in a wide area, and it is easier to secure the adhesiveness of the orthodontic appliance to the dental arch. There is. For example, when the height of the portion corresponding to the lip side is 24 mm, the height of the portion corresponding to the tongue side is 8 mm to 1 mm.
It is preferably 2 mm.

の密着性の確保が更に容易となる利点がある。Furthermore, in the step of manufacturing the orthodontic appliance, the molten orthodontic appliance is manufactured by injecting molten resin from a gate provided at an outer edge at a median position on a side corresponding to a side surface of the lip and avoiding an upper lip zone. Due to this, when the orthodontic appliance was softened in order to be shaped according to the user's dentition or dentition model, a portion close to the upper lip girdle corresponding to the lip side surface occurred during injection molding. Since the molecular orientation is relaxed and the dimensions shrink in the thickness and vertical directions over a wide range, the entire site corresponding to the labial surface falls down and deforms in the direction in which it adheres to the gingival mucosal surface. There is an advantage that adhesion to the dental arch can be more easily ensured.

できるという利点がある。In the anterior teeth or canines, the orthodontic appliances of the present invention are softened and pressed, so that the anterior teeth or canines are embedded and fitted into a portion having a substantially V-shaped cross section in the lip tongue direction. Therefore, there is an advantage that adhesion to the dentition can be ensured by a simple operation.
