Orthognathic surgery requires precise evaluation of sometimes complex dentofacial deformities of the craniofacial skeleton. The success of the surgical plan is not only dependent on the accuracy of the skeletal and dental diagnosis of the deformity, but also on the presurgical predictions of the proposed jaw movements.For precise case evaluation, treatment planning and consequent patient satisfaction, every member of our team here at India Dental Laboratorycarries our core value of providing the highest quality of service to all those who entrust us with their dental wellbeing.
We have a systematic, preciseand intricate approach which helps us provide an end-to-end solution to the patients that require orthognathic surgery
CBCT Case Planning and 3D Modelling
Dental Cone Beam Tomography [Dental CBCT] by Carestream CS 9300;is used to perform a complete facial, profile and cephalometric analysis, which includes facial form, transverse dimensions, facial symmetry and the vertical relationship. It alsoevaluates the position of teeth, bone structures, joints and the airway. This technique helps in estimating the accurate placement of implants, provides 3D orthognathic evaluation, assesses potentially impacted teeth and identifies the nuances of the TMJ complex. These images are sometimes turned into 3D models to assess patients better.
Computer Visualisation of the Final Result
CBCT imaging in tandem with appropriate software and virtual patent-specific models enables the examination of hard and soft craniofacial tissues and their spatial relationships. This is used to generate virtual models and check treatment options, in order to create accurate substitute grafts. In addition, computer visualisation is also used for planning the accurate placement of temporary anchorage devices, if necessary.
A key stepping stone in orthognathic treatment planning is cephalometric prediction tracing, also known as the visual treatment objective. Prediction tracing permits the surgeon to visualise thistreatment objective, therefore allowing refinement ofthe original plan and ascertainment that the correct softtissue profile will be obtained for maximum aesthetic value.
Fabrication of Surgical Splints and Custom Implants
Fabrication of surgical splints and custom implants is the final step in orthognathic case planning. This isdone using CBCT image data after virtually planning a patient’s treatment. Splints and implants can also be fabricated using 3D printing techniques.
