Description

TECHNICAL FIELD

[0001] The utility model relates to a dental treatment appliance, especially to a transparent retainer without jaw pad effect. BACKGROUND

[0002] Orthodontic retainer is an important medical device used after orthodontic treatment, which mainly helps to fix and stabilize the position of teeth that have been corrected. After the teeth are adjusted to the ideal position through orthodontic treatment, the surrounding periodontal tissue and muscles need a certain period of time to adapt to the new position. If there is no retainer to fix, the teeth are easy to return to the original position.

[0003] The existing mainstream retainer has two types:

[0004] One is the Harle retainer, which is composed of a resin base and a metal wire in the anterior tooth area. The resin base covers the palate of the upper jaw, and the metal wire closely adheres to the labial surface of the anterior teeth, which can effectively maintain the position of the upper teeth. This retainer has simple manufacturing process and can be manually adjusted in shape, but has the disadvantages of poor appearance and low comfort.

[0005] The other is a full-mouth transparent retainer made of thermoplastic material, which is made by vacuum suction technology after taking the mold of the patient's teeth. This retainer has good appearance and high comfort, and stable effect on maintaining the dentition. However, the retainer covers the occlusal surface of the posterior teeth, making the wearer unable to bite on their own natural teeth, and raising the occlusal height of the posterior teeth, causing increased tension of the masseter muscle in some patients, exacerbating the bruxism. During bruxism, the posterior teeth may be pressed down, causing changes in the occlusal relationship, anterior occlusal trauma, and potential risks to the temporomandibular joint. SUMMARY

[0006] To overcome the above-mentioned defects, the utility model aims to provide a transparent retainer without jaw pad effect, which can avoid interference of the upper and lower dentition on the occlusal surface, allowing the upper and lower dentition to directly contact each other without causing any early contact point or raising the occlusal surface, thus maintaining the appearance and comfort of the transparent retainer while eliminating the possibility of dental trauma and damage to the temporomandibular joint caused by traditional transparent retainers.

[0007] To achieve the above-mentioned purposes, the utility model adopts the following technical solutions:

[0008] A transparent retainer without jaw pad effect, comprising an upper retainer and a lower retainer, both the upper retainer and the lower retainer being transparent, characterized in that the upper retainer comprises a cavity A that fits both the lingual and buccal surfaces of the upper teeth, and the lower retainer comprises a cavity B that fits both the lingual and buccal surfaces of the lower teeth.

[0009] The upper jaw retainer further comprises an upper jaw retainer occlusal surface cavity, and the lower jaw retainer further comprises a lower jaw retainer occlusal surface cavity, the upper jaw retainer occlusal surface cavity penetrates through the bottom of cavity A, and the lower jaw retainer occlusal surface cavity penetrates through the top of cavity B; the upper jaw retainer occlusal surface cavity and the lower jaw retainer occlusal surface cavity avoid the contact part when the upper teeth and the lower teeth are in occlusion, so that the occlusion condition when the upper teeth and the lower teeth are in occlusion is the same as when the transparent retainer is not worn.

[0010] Preferably, the arrangement of the upper jaw retainer occlusal surface cavity and the lower jaw retainer occlusal surface cavity conforms to the result of Boolean operation, or more occlusal surface area materials are removed on the basis of the result of Boolean operation; the cavities are mainly distributed on the occlusal surfaces of the upper and lower molars and the lingual side of the upper anterior teeth, and avoid the occlusal area.

[0011] Preferably, the arrangement of the upper jaw retainer occlusal surface cavity and the lower jaw retainer occlusal surface cavity conforms to the result of Boolean operation.

[0012] Preferably, the arrangement of the upper jaw retainer occlusal surface cavity and the lower jaw retainer occlusal surface cavity can also remove more occlusal surface area materials on the basis of the Boolean operation.

[0013] Preferably, the number of the cavities A is the same as and corresponds to the number of the teeth of the complete upper jaw dentition, the number of the cavities B is the same as and corresponds to the number of the teeth of the complete lower jaw dentition, and the upper jaw retainer wraps the lingual side and the buccal side of the complete upper jaw dentition, and the lower jaw retainer wraps the lingual side and the buccal side of the complete lower jaw dentition.

[0014] Further, the thickness of the upper jaw retainer and the lower jaw retainer corresponding to the posterior teeth and the cuspid teeth is increased and / or a reinforcing rib is arranged.

[0015] Preferably, the material of the crown covering area of the upper jaw retainer and the lower jaw retainer is high-strength photosensitive resin, and the material of the gum transition area is flexible photosensitive resin.

[0016] The upper jaw retainer and the lower jaw retainer of the utility model have the advantages that:

[0017] 1. The transparent retainer without jaw pad effect disclosed by the utility model removes the interference on the occlusal surfaces of the upper and lower dentitions, so that the upper and lower dentitions can directly contact, no early contact point is caused, and the occlusal surface is not raised, the comfort of the wearer is improved, and the possibility of dental trauma and damage to the temporomandibular joint caused by the traditional transparent retainer is eliminated.

[0018] 2.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings. Example

[0025] This embodiment discloses a transparent retainer, specifically as follows: Figure 1 , Figure 2 As shown, it includes a maxillary retainer 1 and a mandibular retainer 2. Both the maxillary retainer 1 and the mandibular retainer 2 are transparent. The maxillary retainer 1 includes a cavity A11 that fits against both the lingual and buccal surfaces of the upper teeth, and the mandibular retainer 2 includes a cavity B21 that fits against both the lingual and buccal surfaces of the lower teeth.

[0026] The maxillary retainer 1 also includes a maxillary retainer occlusal cavity 12, and the mandibular retainer 2 also includes a mandibular retainer occlusal cavity 22. The maxillary retainer occlusal cavity 12 extends through the bottom of cavity A11, and the mandibular retainer occlusal cavity 22 extends through the top of cavity B2. The maxillary retainer occlusal cavity 12 and the mandibular retainer occlusal cavity 22 avoid the contact portion when the upper and lower teeth bite, so that the occlusal condition when the upper and lower teeth bite is the same as when not wearing a clear retainer.

[0027] The arrangement of the occlusal cavity 12 of the maxillary retainer and the occlusal cavity 22 of the mandibular retainer conforms to the results of Boolean operations.

[0028] like Figure 3 , Figure 4As shown, in this embodiment, the number of cavities A11 is the same as the number of teeth in the complete upper dentition and corresponds one by one, and the number of cavities B21 is the same as the number of teeth in the complete lower dentition and corresponds one by one, the upper retainer 1 wraps the lingual side and the buccal side of the complete upper dentition, and the lower retainer 2 wraps the lingual side and the buccal side of the complete lower dentition.

[0029] In this embodiment, the design of the occlusal surface cavities 12 of the upper retainer and the occlusal surface cavities 22 of the lower retainer is based on Boolean operation, to ensure that the upper and lower retainers still retain the rest of the upper and lower dentition occlusal contact area, can wrap the dentition, thereby achieving the function of fixing the teeth position to the maximum extent without interfering with the occlusal contact of the upper and lower teeth;

[0030] When the upper retainer 1 and the lower retainer 2 are worn on the upper and lower dentition respectively, due to the existence of the occlusal surface cavities of the upper retainer and the occlusal surface cavities of the lower retainer, the upper and lower teeth can realize normal occlusal contact like the Harle retainer, and will not produce the pad-up effect like the traditional pressure film retainer, thereby preventing the lower back teeth caused by using the transparent retainer, and eliminating the possibility of dental trauma and damage to the temporomandibular joint.
