The invention provides a guide unit for 3D printing for dental implant and integral reconstruction of the lower jawbone. The guide unit comprises a bone graft guide plate, a base with dental implant guide holes, a first lower jawbone fixing plate and a second lower jawbone fixing plate. A guide track of the bone graft guide plate and an extending track of the bone graft are consistent in matching. The bone graft guide plate is provided with a plurality of bone graft fixing holes used for connection of the bone graft. The base with dental implant guide holes is arranged on the upper side of the bone graft guide plate, openings of the dental implant guide holes are opposite to the bone graft. The first lower jawbone fixing plate and the second lower jawbone fixing plate are respectively connected to two ends of the bone graft guide plate, are provided with internal side surfaces fitting the surfaces of the corresponding lower jawbone, and are provided with a plurality of lower jawbone fixing holes used for connection of the lower jawbone. With application of the guide unit, lower jawbone reconstruction operation is guided by the bone graft guide plate, while part of operations for dental implanting, such as preparation of implant holes and implanting of implants, are assisted by the bone graft guide plate, and accordingly operation accuracy and success rate are both increased greatly.
Description
Technical field
The present invention relates to medical instruments field, particularly for the guide of the 3D printing that Dental implantion and mandibular bone integration are rebuild.
Background technology
Tumor invading, inflammation, wound and radiotherapy are the main causes causing jawbone to destroy, operative treatment usually needs excision bulk jawbone, necessarily cause patient facial region's external defects and the forfeiture of occlusion masticatory function, this is accomplished by superior reconstruction technology, intercepting the nonweight-bearing one section of fibula of autologous shank, fashioning into the shape similarity metric jawbone of jawbone is most currently used means.
But, colleague is primarily focused in the form of reconstruction of jaw more both at home and abroad at present, and namely the outward appearance recovery aspect of patient, but ignores the recovery of the occlusion masticatory function of patient, and the occlusion bad Quality of Life to patient of masticatory function is bigger in fact.A large amount of reconstruction of jaw cases that we complete in early days, have recovered patient's outward appearance, the difficulty but the most of patients later stage has a denture made smoothly, have impact on the recovery of occlusion masticatory function.The fibula transplanted carries out the reparation of removable denture, often maintenance is poor, masticatory efficiency is low, and Dental Implant maintenance is good, it is the most ideal style recovering meshing functions, is conducive to having a denture made, particularly being conducive to the reconstruction of jaw scheme of Dental Implant is pursuing a goal of Oral and Maxillofacial Surgery and Prosthodontics doctor, but often because the deficient accuracy of reconstruction of jaw position and deficient reasonability, or implantation body's implant angle or the degree of depth not good enough, cause that Most patients loses Dental Implant chance.So being badly in need of a kind of guide having and guiding Dental implantion and mandible reconstruction function, it can be ensured that while fibula is precisely transplanted, implantation hole preparation and implantation body is guided to implant.
Summary of the invention
