Based on 3D CT image reconstruction system for analysis and other aspects of the jaw morphology

stability and aesthetic dental implanting depend on 3D position of the implanting in the jaw. Since that

this paper proposes a full-featured interactive positioning method and discusses three-dimensional model of the coordinate transformation and coordinate data extraction technology. Combined the function of extraction database in VTK with the characteristics of needle puncturing for points

it obtains three-dimensional image coordinates of mandible by interactive operations to achieve the implant positioning of three-dimensional jaw image. The researchers compare this with the coordinates of the intelligent positioning of the implant. And through minor adjustment

the latter reduces the errors such as in the direction of the implant and implanting length

which effectively improves the accuracy and security of the virtual dental implant navigation system.
