6.7.2 Introduction
Co-ordinated orthodontic/surgical treatment, which allows the predictable
management of dento-facial disproportion, is largely a development of the
latter third of the 20th century. Traditionally, the diagnosis, treatment planning
and post-operative evaluation of patients requiring such treatment has
relied heavily on the use of cephalometric analysis. This has enabled the
two-dimensional quantifi cation of dental and skeletal relationships both
before and after treatment, with reference to normative data in tabulated
or template form (1, 2, 3).
However, the recent development of three-dimensional measuring techniques
has allowed a more clinically valid quantifi cation of deformity and
assessment of surgical outcomes (4, 5, 6, 7, 8, 9, 10). Computed tomography
(CT), magnetic resonance imaging (MRI) and fi nite element analysis (FEA)
have all recently been employed in surgical planning and the visualization
of treatment objectives (11, 12, 13, 14, 15, 16, 17, 18, 19). This case study
