Technical Field
The invention belongs to the technical field of denture structures, and particularly relates to an implant denture with a spring damper telescopic abutment.
Background
The implant prosthesis made after the upper and lower teeth are partially or totally lost in stomatology is generally called implant denture. The conventional artificial tooth implant is generally composed of an implant, an abutment and an implant crown, and due to the rigid connection among the above components and the osseointegration between the implant and the alveolar bone, the stress concentration phenomenon occurs in the bone tissue around the neck of the implant, thereby causing bone absorption and damage to the implant and the abutment. In addition, because the rigidly connected implant denture lacks elasticity, the implant crown of a patient is lower than that of a normal natural tooth clinically, so that the patient can not bite the denture firmly when biting the denture slightly and can contact the denture when biting the denture heavily, and even then the problem of stress concentration cannot be completely avoided.
