Bone taking guiding plate printed through three-dimensional technology for mandible ascending limb part

Abstract

The invention relates to the technical field of medical treatment, in particular to a bone taking guiding plate printed through a three-dimensional technology for the mandible ascending limb part. According to the bone taking guiding plate printed through the three-dimensional technology for the mandible ascending limb part, the best shape and size of a required bone block are designed according to the best transplantation scheme for the autogenous bone block in a transplantation accepting area. According to the best shape and size of a transplantation bone block, the thickness and shape of anosteotomy guiding groove of an osteotomy guiding assembly are designed. The thickness of the osteotomy guiding groove coordinates with the length of a drill needle and is equal to the difference value between the length of the drill needle and the thickness of the bone block required for a corresponding part, and the effect of controlling drilling depth in the bone can be achieved. The shape of the osteotomy guiding groove is consistent with the shape of the surface of the bone block subjected to transplantation. Therefore, the shape and size of the transplantation bone block can be controlled to the largest extent. The three-dimensional technology is adopted for printing the titanium alloy bone taking guiding plate based on a tooth-borne type. The guiding plate is fixed through the mandibular dentition, and the fixation end is stable and not loose. The other end of the guiding plate is an osteotomy guiding groove end and closely fits the bone surface of the mandible ascending limb part.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a three-dimensionally printed mandibular ramus bone-taking guide plate. Background technique [0002] Dental implants are considered to be the best treatment for patients with dentition loss and dentition defects, but the insufficient amount of upper and lower alveolar bone is one of the most important obstacles to the successful implementation of dental implants and long-term success after treatment . The use of bone augmentation technology can increase the width and height of the alveolar bone to a certain extent. It is a major problem in the field of implantation to greatly increase the height of the alveolar bone. Block autologous bone grafting is still the gold standard for vertical bone augmentation. Autologous bone blocks can be obtained from the chin, ramus of the mandible, and cheekbones. [0003] In the past, doctors performed surgical operations based on experience...

AI Technical Summary

Problems solved by technology

[0003] In the past, doctors performed operations based on experience, and the following problems often existed in mandibular ramus bone harvesting: (1) The bone harvesting site was inaccurate

(2) It is easy to damage local important tissues, blood vessels, etc.

(3) The operation time is long and the operation trauma is large
