Surgery first approach

3.  Diagnosis and treatment planning forms the basis of successful treatment
planning.
 Surgery-first orthognathic approach (SFOA) is fast becoming an accepted
modality as part of jaw surgery and involves meticulous treatment planning and
execution.
 Emphasis is laid on the understanding and visualizing of the post-surgery
‘transitional occlusion’.

11.  SFOA utilizes the sudden surge of cyclical sequence of bone modelling and remodelling
events that ensues subsequent to osteotomy cuts made for the correction of jaw
deformity.
 Buschang and colleagues observe that corticotomies hasten tooth movements because
the ‘surgical insult’ produces RAP, and greater the injury, the more the tooth
movement.
 Liou et al. studied the postoperative changes in bone physiology and the
corresponding responses in the dentoalveolus in orthognathic surgery subjects.
 Zingler et al. in their prospective cohort study evaluated biological changes using
GCF markers

12.  In order to take cognizance of the dentofacial structures and their posed
complexities, orthodontists expend a plethora of 3D techniques and modalities,
such as
 3D facial morphometrics,
 3D non-contact laser scan
 3D cone beam computed tomography (CBCT),
 Stereolithography
 3D ultrasound holography
 Finite element modelling,
