RESUMO
The biennial symposium of the Education, Research and Development Group (ERDG) of the New ZealandAssociation of Orthodontists (NZAO) was held in Queenstown on August 17 and 18, 2007. Following a well-tested format, the symposium considered the effects of expansion of the dental arches in the three planes of space and over time, a timely but difficult topic given the current fashion to avoid the extraction of teeth to correct dental crowding. The findings reported here represent the consensus reached by delegates attending the symposium.

This report describes a combined orthodontic and orthognathic surgery approach to the treatment of open bite in an adult female. An aesthetically pleasing and stable result was achieved in which the Intercuspal and Retruded Contact Positions were coincident. The functioning occlusion exhibited bilateral canine rise and an absence of non-working-side interferences on lateral excursion. Incisal guidance with disclusion of the posterior occlusal surfaces occurred on protrusive function. There were no signs or symptoms of temporomandibular joint dysfunction before or after treatment.

This report describes a combined orthodontic and orthognathic surgery approach to the treatment of extreme deep overbite in an adult male. An aesthetically pleasing and stable result was achieved without extensive restorative or prosthetic treatment and their inevitable sequelae. The functioning occlusion exhibited bilateral canine rise and an absence of non-working side interferences on lateral excursion. Incisal guidance with disclusion of posterior occlusal surfaces occurred on protrusive function.

Functional orthodontic appliances have recently captured the interest of a significant portion of the dental profession. In numerous articles and short courses, functional appliances have been portrayed as a new, low cost, easily managed and completely safe treatment modality. Claims have been made that they can make mandibles grow, can align the dentition without the need for extractions, and that because such treatment effects are achieved 'physiologically' they are thus inherently stable. Do functional appliances really work? The historical background to the development of functional appliances is described and the results of a number of clinical investigations are compared and discussed. Comment on the implications of functional appliance therapy is given and finally, a statement as to the rational use of functional appliances in practice is suggested.
