Description of the Invention: [Technical Field] The present invention relates to a stent structure, and more particularly to a stent structure which is simple in surgical procedure and has good structural support force to facilitate bone tissue regeneration. [Prior Art] The development of artificial implants has gradually matured, and the success rate can usually be as high as 90% or more, so it has become an option for most dentists to treat. Natural teeth support the force in the mouth by the alveolar bone. The difference between the artificial implant and the natural tooth is mainly that there is no periodontal ligament, but the artificial implant also needs to rely on the bone to support the force. Therefore, the quality of the bone The amount inevitably affects the force of the artificial implant, and also affects the height of the surrounding gums, which in turn affects the appearance. After the common tooth is removed, the bone will be reshaped, and the lack of big eve will be filled by soft tissue. The normal teeth also have the ability to cause bone damage due to periodontal disease and other factors.

Artificial implants rely on bones to support the force, while the gums protect the bones and show the appearance. 'Normal and healthy silver height depends on the bones underneath. Therefore, whether the beta head affects the force of the implant, it also affects the surrounding gums. The height, which in turn affects the aesthetic performance. The bone is the foundation of artificial implants. With a solid foundation, the artificial implant can be planted in the best position. 'The artificial implant can have the best shape and let the implant reach the best stress condition. Therefore, the patent of Taiwan Patent No. M327222 "Improved structure of bone path tissue regeneration guide" provides an improved structure of a bone path tissue regeneration guide, which comprises a soft tissue isolation membrane and a tissue regeneration guide material, soft tissue. The barrier film is a soft sheet-like body, and the tissue regeneration guiding material is combined on one side of the soft tissue barrier film, which can be operated to fill the defect portion of the gum bed or the bone proliferative site, and covered with a soft tissue barrier film. The protection is formed on the upper part, and finally the cut coated tissue is sutured, and then the wound can be restored. In this case, since the soft tissue isolating membrane on the surface layer has better structural strength, it can easily support the regeneration of the bone retina as needed. The shape of the bone formed, but in fact the non-absorbable soft tissue barrier maintains space capacity is still insufficient 'easy to collapse and must be removed Sheet removed, the wound is large, it can not be applied to an immediate implant surgery, so it is necessary to the improvement. 201215366 [Summary content]
