The periodontium plays a predominant role in the healthy stability of the dentition in general and of canine teeth in particular. After reviewing the make-up of healthy periodontal tissue and evaluating the situations where it is at risk, we describe different techniques of muco-gingival surgery that are applicable to canines.

We then illustrate the integration of periodontal data in treatment planning for orthodontic treatment of impacted canine teeth with clinical cases where our therapeutic choices have a certain original quality.

The exchange of position of two adjacent teeth constitutes a transposition. Maxillary canines are rarely affected; transpositions of upper canines occur in only .2% of the orthodontic population. They can be detected early in radiographic examinations and later, clinically, after they begin to erupt. Most writers affirm that transpositions, which are often associated with other dental anomalies, are caused primarily by some genetic defect but that local factors may contribute to their development. Practitioners should consider their muco-gingiva environment as an important factor in their evaluation of the iatrogenic risks that might accompany treatment and consider improving soft tissue status as a preparatory soft tissue therapeutic procedure. They must also differentiate between cases of incomplete transposition and partial complete transposition, which can almost always be successfully treated, from cases of total complete transposition that are relatively difficult if not impossible to treat.

The aim of this article is to present a precise periodontal terminology that orthodontists can use to clarify communication between orthodontists treatment and their patients. What’s mean periodontal issues that arise in adult orthodontic treatment, what the purpose of the discussion? In general terms we refer, of course, to mechano-therapy for adults and to the periodontal diseases that arise with this class of patients and to the treatment that is available for these maladies. Orthodontists who treat adult patients and record procedures in careful way need to rely upon a precise periodontal vocabulary so that, as group leaders, they can communicate effectively with other members of the inter-disciplinary treatment team as well as with patients. In the management of this effort, orthodontists are responsible for referring patients to periodontists when it’s necessary and for keeping the lines of communication open between patients, andperiodontists.
