A Systematic Approach for Splint Fabrication in Orthognathic Surgery: Case Series.

Orthognathic surgery involves the surgical manipulation of the facial skeleton to correct anatomical and functional deformities. Model surgery is an integral part of orthognathic surgery. It gives the three-dimensional understanding of the post-operative relationship of the jaws. Orthognathic model surgery has been used to assist the surgeon in repositioning the upper and lower jaws into a predicted position. Model surgery planning has generally been carried out using one of two techniques - The lock wood key spacer technique or Eastman Dental Hospital anatomically orientated model surgery technique. This work presents our experiences in model surgery using modified Eastman’s technique.
