Problems solved by technology

The cost of designing and generating a micro-implant anchorage digital guide plate is equivalent to the sum of the micro-implant anchorage material itself and the cost of clinical operation and treatment, so few clinicians will use precision implantation

Abstract

The invention discloses a designing and manufacturing method for personalized precise implantation of a micro-implant anchorage. The designing and manufacturing method comprises the following steps: 1) manufacturing a marking model with a positioning grid and scanning the marking model; 2) performing registration on the marking model and CBCT jaw bone data; 3) virtually implanting the micro-implant anchorage through the positioning grid; 4) checking a virtual micro-implant anchorage position; 5) transferring an implantation position and direction on the marking model; 6) manufacturing a personalized implantation guide plate; and 7) guiding implantation and recovering core auxiliaries. A bidirectional positioning grid with three-dimensional attributes is introduced, in a process of designing a virtual implant, the virtual implant is formed by connecting positioning holes, the virtual implant is imported into the jaw CBCT data to check, adjust and determine the optimal implantation position and direction, and the personalized implantation guide plate is manufactured after transferring is carried out on the marking model. The positioning controllability is good, the repeatability is high, reverse engineering design and 3D printing manufacturing do not need to be conducted on the guide plate, and the design time is shortened to a certain degree, and the manufacturing cost is reduced to a certain degree.

Description

Technical field [0001] The present invention relates to an orthodontic clinical treatment, and more particularly relates to a design method of a micro implant anchorage personalized precise implantation. Background technique [0002] Currently clinical implantation of micro-implant anchorage, most of the time with all the experience of clinicians to assess the possible security implant position and orientation, in some cases also reference CBCT images, but only to observe the structure, not the situation with the disease within the population for accurate combination. If you want to be precise implantation, the key is to use reverse engineering, virtual three-dimensional reconstruction of dentition after implantation and partial jaw, and then make digital guides, 3D printing after use. This technique requires specialized in the design phase of digital technology staff to produce phase requires a special 3D printer, a technical and material costs are high. Design and creation of a...
