Abstract
Set-up models are used for a wide variety of dental procedures, from bridge and crown elaboration, maxillofacial surgery planning and for the indirect bonding of lingual brackets. The first step in the construction of a set-up model is the sectioning of the malocclusion model. Manually sectioning malocclusion models is a laborious, often imprecise process than generates a large amount of dust. In this article we present the JAEL system-a joystick-controlled, remote-operated machine which quickly, precisely and cleanly sections malocclusion models for use in procedures such as prosthetic appliances, maxillofacial surgical predictions and the indirect bonding of lingual brackets.
Highlights
The sectioning of dental models is an important part of a variety of medical procedures, including orthognathic surgery planning [1], the indirect bonding of lingual orthodontic brackets [2] or the design of many dental reconstructions
The set-up facilitates the creation of a good final occlusal relationship and allows the orthodontist to visualize the final position of each tooth. This is important in the case of tooth size discrepancies.The fabrication of resin or metal bracket bases for the indirect bonding of lingual orthodontic brackets is only possible using a set-up model [4]
We note that the manner in which a malocclusion model is sectioned depends on the use to which the set-up model will be put; in particular, if a set-up model is to be used for diagnostic purposes, to demonstrate a treatment outcome to a patient, or for the indirect bonding of lingual brackets, the malocclusion model must be sectioned into individual teeth, and each tooth must be further sectioned in order to provide space for repositioning [10]

It is hoped that use of the system will make the sectioning of malocclusion models easier, safer and more precise, and reduce the time needed to construct set-up models
