A Modern Approach to Bidimensional Technique
by Dalessandri Domenico
The Bidimensional Technique, conceived by Prof. Gianelly of Boston University over forty years ago, is a treatment strategy designed to facilitate the control of the torque of the maxillary incisors during their retraction and the mesialization of the posterior dental elements of the mandibular arch through sliding mechanics. A distinctive feature of this technique is the use of a .018 "x .022" stainless steel working archwire associated with brackets with .018 "slots on the incisors and .022" slots on the other teeth. This archwire completely fills the slot of the incisors by precisely controlling the inclination and is, on the contrary, undersized compared to the slots of the posterior teeth, within which it therefore slides easily. The use of well-coded treatment protocols divided into distinct phases, associated with diagnostic principles and the formulation of the treatment plan with a well-identified logical basis, are the basis of the high predictability of orthodontic treatments carried out by applying the Bidimensional "philosophy", which has nevertheless continued to evolve over the years by integrating the use of more effective anchorage management systems such as TADs, drawing on more advanced tools for the analysis of smile aesthetics such as Digital Smile Design and getting to influence with its own distinctive principles also the biomechanical planning of orthodontic treatments conducted by means of modern therapeutic devices such as clear aligners. During this cases discussion session, the most advanced evolutions of the Bidimensional Technique will therefore be presented, giving the participants the opportunity to see its fundamental principles applied to a wide spectrum of malocclusions, discuss its clinical strategies and share their cases with the speakers.
After this lecture, you will be able to recognize the different elements to be evaluated during the diagnostic study of a clinical case conducted by applying the principles of the Bidimensional Technique.
After this lecture, you will be able to define the most effective biomechanical strategy for the correction of a wide spectrum of malocclusions by applying the Bidimensional Technique.
After this lecture, you will be able to evaluate the achievement of the ideal treatment goals and the efficiency of the Bidimensional Technique.
