DIGITALISATION OF ORTHOGNATHIC SURGERY: A PARADIGM SHIFT IN TREATMENT
PLANNING AND SURGICAL EXECUTION

Soh CL, Chan MF, Tan PG
Orthognathic surgery is surgery of the jaws aimed at repositioning the maxillary-
mandibular complex into a more functional and aesthetic relationship. It is primarily done
after a period of fixed orthodontics and conventionally follows a planning protocol
utilizing manual methods of dental impressions, facial measurements and translation of
radiographic landmarks from a 2-dimensional lateral skull x-ray. This surgery is employed
for patients with dentofacial deformities that cannot be corrected by orthodontics alone.
The rise of digital planning and 3-dimensional printing technology has enabled this surgery
to be carried out in a novel way; with the aim to not only improve surgical accuracy but
reduce operation time and minimize post-operative complications as well when
compared to conventional manual methods. We describe 2 cases done via digital planning
and 3-dimensional printing technology; one done using a completely wafer-less method
and another using a mixed digital-analogue model.
