Description
Technical field:
The utility model belongs to oral cavity Cosmetic surgery field, in particular to a kind of positioning and guiding supported based on tooth
Device.
Background technique:
The initial gear divisions such as tooth-implanting operation or orthodontic treatment are performed the operation the auxiliary of no effective instrument and equipment, simple by doctor
Raw sense is determined in a manner of manually estimating needs to plant or need the position of orthodontic treatment, the risk of operation compared with
Greatly.With the development of technology, doctor develops the accurate positioning mode by surgical guide to reduce operation risk.
The positioning method of existing gear division surgical guide mainly has jawbone support, mucous membrane support and tooth to support three kinds of sides
Formula.Jawbone support is to be supported using jawbone as the positioning datum of surgical guide and supporter, determines the position of planting body, is performed the operation
Need to open mucous membrane very big range in operating process, it is bigger to patient trauma；Mucous membrane support is to utilize patient's mucous membrane group
The positioning datum and supporter as surgical guide are knitted, determines the position of planting body, to trouble for the mode supported compared to jawbone
Person's wound is small, but needs to solve the problems, such as simultaneously to be accurately positioned.Dental branches support refers to using tooth remaining in oral cavity as surgical guide
Positioning datum and supporter, the position of planting body is determined according to remaining tooth position, shape information, with jawbone support mode phase
Smaller than its operation wound, its positioning is more accurate compared with the mode of mucous membrane support.The patient that there is remaining tooth for oral cavity comes
It says, the use of the surgical guide auxiliary operation supported based on tooth is preferred option.
It is mostly packaging type plastic material form that traditional gear division, which guards guide plate, and gear division surgical guide requires to plant in gear division
Should have in operation implementation process be not likely to produce deformation, it is not pliable, can cool down, the characteristics such as operating space is big, visual range is wide.
And there are these drawbacks for the design of conventional plastic guide plate, directly affect the security implementation of implant operation.
The information disclosed in the background technology section is intended only to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition is already known to those of ordinary skill in the art existing
Technology.
Utility model content:
The purpose of this utility model is to provide a kind of locating guide devices supported based on tooth, to solve traditional package
