[0039] Although the present invention is a combined oral periphery supporter, the upper periodontal tension mechanism 10 or the lower periodontal tension mechanism 20, the left periodontal tension mechanism 40 or the right periodontal tension mechanism 50 can also be used alone to provide unilateral support in the oral cavity.

[0040] Although the detailed technology in the upper periodontal tension mechanism 10 or the lower periodontal tension mechanism 20 is protected in the present invention, those skilled in the art can easily transplant the detailed technology to the left periodontal tension mechanism 40 or the right periodontal tension mechanism 50. Therefore, the detailed technology in the upper periodontal tension mechanism 10 or the lower periodontal tension mechanism 20 is also suitable for the left periodontal tension mechanism 40 or the right periodontal tension mechanism 50 and should also be protected.

If the upper periodontal tension mechanism 10 and the upper periodontal tension mechanism 20 or the left periodontal tension mechanism 40 and the right periodontal tension mechanism 50 are an integrated structure, the bending and elastic structure between the upper periodontal tension mechanism 10 and the upper periodontal tension mechanism 20 or the left periodontal tension mechanism 40 and the right periodontal tension mechanism 50 can generate a vertical or horizontal elastic force between the upper periodontal tension mechanism 10 and the lower periodontal tension mechanism 20 or between the left periodontal tension mechanism 40 and the right periodontal tension mechanism 50, which is beneficial for supporting the upper and lower oral cavity;If a combined structure is used to form an integral structure by combining the upper periodontal tension mechanism 10 and the upper periodontal tension mechanism 20 or the left periodontal tension mechanism 40 and the right periodontal tension mechanism 50, and a support spring and a tension adjustment mechanism are provided between the upper periodontal tension mechanism 10 and the upper periodontal tension mechanism 20 or the left periodontal tension mechanism 40 and the right periodontal tension mechanism 50, the spring can be used to generate a vertical support force, and the adjustment mechanism can be used to adjust the size of the mouth opening, thereby stretching the periodontal muscles. This can facilitate the dentist's operation and reduce the patient's mouth opening force, thereby reducing patient fatigue. In short, the present invention can support the oral cavity in the vertical and left and right directions, exposing the teeth and periodontal area, broadening the dentist's field of view within the oral cavity, reducing the patient's fatigue from prolonged mouth opening, stabilizing the mouth shape, and facilitating the dentist's tooth shaping and treatment.
