A review of the management of anterior open bite malocclusion.

Anterior openbite (AOB) malocclusion is considered one of the most demanding challenges for the orthodontist, as occlusal correction is difficult, facial aesthetics may be unsatisfactory and the incidence of relapse is high. A retrospective cephalometric study of 19 consecutively treated AOB patients is presented. The follow-up ranged from 12 to 48 months. Several case reports are included to demonstrate a contemporary approach combining orthodontic treatment and orthognathic surgery. The results indicate that overbite was maintained with good vertical skeletal stability. Anteroposterior position was less stable. Posterior facial height was maintained or decreased, and there was no evidence of postsurgical maxillary incisor movement. It is concluded that occlusal stability and clinical success may be anticipated when certain criteria are adhered to in all phases of treatment, and that a coordinated surgical-orthodontic treatment approach currently offers the best chance of attaining occlusal stability, improved function and satisfactory aesthetics.

An example of the use of quantitation in histological diagnosis by a comparison of normal human cheek mucosa and cheek mucosa affected by lichen planus.

As an example of the use of quantitation in histological diagnosis the features of normal human cheek mucosa (NHCM) and non-ulcerative lichen planus of the cheek mucosa (LPCM) have been systematically studied and quantified in order to establish normal and pathological features which are constant. The technique enabled the quantitative verification of previously held concepts relating to NHCM and LPCM. A number of interesting features which have been given little attention in past literature were also noted. It is proposed that a reliable quantifiable range of characteristic histological features should be established for use in diagnosis where possible rather than relying on the subjective approach currently employed.
