ABSTRACT
After an unsuccessful period of orthodontic treatment (by another provider), state-of-the-art methods are used to gain a patient's trust. Diagnostic set-ups and digital imaging techniques help the patient feel confident enough to accept a comprehensive multidisciplinary treatment plan.

The purpose of this study was to evaluate the accuracy of computerized video imaging in predicting the soft tissue outcome of extracting four premolars in adults. The pretreatment and posttreatment cephalometric and facial photographic records of 31 previously treated, nongrowing patients were digitized and computer-generated cephalometric VTOs and video images were compared with the known outcomes. The results showed that both the VTOs and video images were accurate enough to be used for patient education and communication, as well as for diagnosis and treatment planning. While lay people found that the predicted video images adequately resembled the actual outcomes, orthodontists were more critical, particularly of the lower lip area where variable soft tissue responses to treatment were noted.

The purpose of this study was to evaluate the accuracy of computerized video imaging in predicting the soft tissue outcome of growth modification treatment for skeletal Class II malocclusions. Pretreatment and posttreatment cephalometric and facial photographic records of 22 mixed dentition (8 to 10 years old) and 20 adolescent (12 to 14 years old) patients were digitized, and the known outcomes were compared with computer-generated VTOs and video images. The predicted video images were found to be reasonably accurate for the mixed dentition group, but unacceptable for the adolescent group. When graded by a panel of judges, orthodontists were far more critical of the findings than their lay counterparts. These results emphasize the potential of video imaging as a communication medium, rather than as a diagnostic tool for growing patients.

This paper discusses the current capabilities and limitations of video imaging. Probable future applications are suggested, including the use of video imaging as an adjunct for esthetic diagnosis and treatment planning and as a means of providing realistic representations to patients of probable treatment outcomes. The widespread use of video imaging to facilitate interactive informed consent and rapid interspecialty communication and transfer of data is predicted and discussed.
