The Orthodontics is the branch of dentistry that studies the different anomalies of the constitution, development and position of teeth and maxillary bones. It aims to prevent, eliminate or mitigate such abnormalities, maintaining or returning the organs of chewing in the most correct position possible in respect of the face, periodontal tissues, muscles


This is what the Americans call the six upper front teeth (canine to canine). They are the teeth that are most noticeable and with which we "smile". Their alignment is "cosmetics".


It aims to align the teeth of the two arches by seeking a ratio of the molar and canine class I, a correct overjet and overbite and a correct relationship of the tooth with the bone of the jaw and jaw.


... of Dr ROTH and Dr WILLIAMS aims to align the teeth of the two arches in accordance with the aesthetics of the face, facial muscles, periodontal tissues and temporomandibular joint (TMJ).

The oldest of the specializations

Orthodontics is the oldest of the specializations in dentistry and an orthodontics specialist has at least three years of university education in addition to those of dental training. More and more scientific studies prove that the ratio of teeth, muscles and temporomandibular joint (TMJ) is the primary key to long-term health and stability of the chewing system. Many orthodontic schools focus primarily on alignment of teeth by neglecting to teach students how to correct the functional relationship between the teeth and the temporomandibular joint.

Get an attractive smile while respecting facial aesthetics and temporomandibular joint

Orthodontic training

Dr. Nicola De Simone, specialist in Orthodontics, is proud to have completed his training at the Roth-Williams International Society.

Here he took a special advanced course of teaching Orthodontic Philosophy of Dr. Roth-Williams. Orthodontists of this course must demonstrate how to correct the bite and align the teeth of patients to get an attractive smile in respect of facial aesthetics and temporomandibular joint. For the orthodontist Roth-Williams, orthodontics is a service for health and not simply a cosmetic.

It’s the only one of its kind in the whole world! The format of the intensive course allows doctors to study and learn information, put into practice the necessary clinical skills, gradually transforming their practice.

The method of study and work of orthodontists Roth-Williams is very different from the ways of traditional practice.

The patient will have to choose between different philosophical views of the orthodontic specialty and this is very important :

  • A group of orthodontists believes there is a strong functional relationship between teeth, muscles and joints of the jaw. This relationship must be carefully respected both at the diagnosis stage and throughout treatment.
  • The other group of orthodontists believes that this relationship is little or not at all relevant and that the alignment of the patient’s teeth will be the goal of treatment.

How do you choose?

The orthodontist Roth-Williams carefully considers the tooth/muscle/joint ratio from the beginning to the end of the orthodontic treatment and, As a result, its practice can be easily distinguished from those seeking the simple ‘alignment of teeth’.

For example, the orthodontist Roth-Williams:

  • Rarely performs examination, diagnosis and treatment plan in one appointment. Most often it collects data from the first visit, photos, Rx, models and takes the time to study before explaining the individualized treatment plan and treatment options.
  • It can routinely mount plaster dental models on a tool, the articulator, which is crucial to study the functional relationship between teeth and joints.
  • Often requires images of joints.
  • Plans to include in the course of treatment also the second molars, which are the teeth closest to the joints, thus producing a profound effect on the functional movement of the jaw.
