Prescriptions

The name ‘Trevisi’ is synonymous with Dr. Hugo Trevisi, who co-founded the globally recognized McLaughlin/Bennett/Trevisi treatment philosophy.

With the Trevisi Prescription, the proven expert in self-ligating multiband appliances not only presented his own bracket technique, but also a new treatment concept. This is based on the optimization of the sliding mechanics and the use of light and constant forces. The archwire is allowed to move freely in the bracket slot, which reduces the classic friction and increases the efficiency of the sliding mechanics. In addition, the Trevisi Prescription allows for better three-dimensional control of tooth movements.

Preset appliances were first introduced to orthodontics nearly fifty years ago. The Andrews Straight Wire System® has been altered, refined, and modified by many clinicians. The original idea, of course, was to eliminate or greatly reduce wire bending in finishing cases.

The objectives of the Roncone PDS prescription include the elimination of posterior balance disturbances as well as the elimination of excessive anterior contact.

Since Lawrence F. Andrews introduced the straight-wire appliance in 1970, several techniques have emerged that modify certain torque, tipping, and rotation values, while still largely preserving the core elements of Andrews’ original prescription. In many instances, these adjustments were aimed at addressing specific challenges in orthodontic biomechanics, although in some cases, the rationale for the changes remains unclear. Dr. Ronald H. Roth introduced the bracket values defined according to his philosophy a little later.

The Roth Prescription reflects the view that the correction of malocclusion must be carried out in harmony with a well-functioning occlusion. Aspects such as facial and dental esthetics, functional occlusion and temporomandibular joint position, as well as stability and periodontal health, should be included in the assessment.

The Edgewise technique marks the early development of fixed orthodontic treatments. Unlike the later Straight-Wire technique, Edgewise brackets lack pre-programmed values. Instead, tooth movements and the desired alignment are achieved solely through the adjustment and bending of the archwires.
