Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] A 3D printed personalized cage-shaped dental bone graft guide plate, characterized in that: the shape of the bone defect area is reconstructed by three-dimensional modeling, the bone graft guide plate is a cage-like structure, and a part is in contact with the bone defect part of the alveolar bone The cage is used to guide the implantation of bone meal, and the other part is the cage cover that is in contact with the soft tissue to restore the contour of the gums.

[0019] Mandibular first molar bone grafting is taken as an example. The implementation of a 3D printed personalized cage-shaped dental bone grafting guide includes the following steps:

[0020] (1) Firstly, for the bone defect in the mandibular first molar area of ​​the patient, three-dimensional reconstruction is performed based on CT imaging technology, and the size and shape of the...

Abstract

The invention provides a 3D printing personalized cage-like tooth bone grafting guide plate. The guide plate is characterized in that a bone defect form in a region needing bone grafting is reconstructed by three-dimensional modeling, and a support is of a cage-like structure, wherein one part of the support is like a cage used for making contact with a bone defect part of alveolar bones and guiding bone powder grafting, and the other part of the support is like a cage cover used for making contact with soft tissue and restoring contours of gingivae. In a clinical bone graft surgery, firstly, the cage is placed in the bone defect region, bone power is then placed, the cage is covered by the cage cover, and therefore a cage-like region which can guide bone powder to be grafted into a specific position, maintain the form of the bone defect region and support the form of the soft tissue, at the same time, magnesium ions promoting bone formation are released out after cage-like bone grafting guide plate materials are degraded, and the quality and speed of bone regeneration are further improved. Not only can the use of guided tissue regeneration membranes be reduced, but also the clinical operation difficulty of doctors can be reduced.

Description

technical field [0001] The invention relates to a dental bone grafting guide plate, in particular to a manufacturing method and an application thereof of a 3D printed personalized cage-shaped dental bone grafting guide plate which can assist a stomatologist in performing bone grafting during the bone grafting process. Background technique [0002] In recent years, due to its high success rate and good long-term restoration effect, implant restoration has been favored by more and more patients and oral clinicians, and has become the first choice for the restoration of missing teeth. However, tooth loss often causes alveolar bone resorption, resulting in alveolar bone atrophy and insufficient bone in the implant area, and the success of implant surgery is closely related to the alveolar bone condition in the implant area. Insufficient alveolar bone height and width often lead to implant failure or failure of implant surgery. The height of the remaining alveolar bone in the ed...
