A novel occlusographic analysis for assessment of mandibular narrowing.
Accurate evaluation of transverse mandibular dimension is a controversial and rarely addressed topic. Although mandibular narrowing via symphyseal osteotomy and bilateral ramus sagittal split was initially described more than 30 years ago, the development of a simple and effective clinical tool to assess the outcome of such procedures remains elusive. Although many quantitative modalities, such as frontal cephalogram, tomography, and interdental distance measurement, are in current use, each possesses significant liabilities. Prompted by a need for improved accuracy, simplicity, and reliability in the clinical setting, we developed and used a novel occlusographic analysis. The Madjidi occlusographic analysis does not rely on the position or tilt of moveable teeth; therefore, orthodontic changes do not influence quantification of mandibular position. Contours and mandibular relationships of interest are seen clearly, radiation is unnecessary, and occlusographic analysis can be quickly reproduced in the clinical setting using widely available materials. Although the evaluation of transverse mandibular dimension after surgical narrowing is frequently more controversial than accurate, the Madjidi occlusographic analysis is a reliably simple solution to an often complex problem.
