FACE Evolution II

In line with Roth’s basic principles, the prescription has been further developed and is now available in a modified bracket prescription developed by the internationally renowned FACE Group.
FACE’s treatment philosophy focuses on a functionally and aesthetically ideal treatment outcome.
The latest technologies, which enable even more precise diagnostics, treatment planning and therapy are used to achieve this. The latest modification is now available in the form of FACE Evolution II. It is characterized by modified torque values for the brackets for the upper and lower canines and premolars, as well as for the first and second upper molars. They were changed from -7° to 0° in the upper 4s and 5s, and from -17° to -12° (first premolar) and from -22° to -17° (second premolar) in the lower premolars. The foundations of these modifications were obtained by evaluating CBCT images taken before and after treatment. This evaluation suggests changing the torque of some teeth to better position the tooth roots in the alveolar bone and to thus avoid dehiscences and/or to boost stability and periodontal health.


Dr Richard P McLaughlin, Dr John C Bennett and Dr Hugo Trevisi presented their own prescription after gaining around 20 years of clinical experience with the straight wire appliance. They used the Andrews standard values and changed them from a clinical point of view, especially with regard to the torque. Their philosophy reflects a highly systematic approach and is based on a comprehensive system of brackets, exact requirements for positioning the brackets on the teeth, various arch shapes and the use of gentle, constant forces.


Starting from Lawrence F Andrews’ launch of the straight wire appliance in the 1970s with torque, tip and in/out values programmed in the slot and base, it has been modified time and time again. Dr Ronald H Roth presented the bracket values defined according to his philosophy soon after. The Roth prescription reflects the view that a malocclusion should be corrected in line with an efficient occlusion. Aspects such as facial and dental aesthetics, functional occlusion and mandibular joint position, plus stability and periodontal health, should be included in the diagnosis in this regard.
