“…However, these data may be misleading in the case of bilateral canine impactions due to overlapping images of the two teeth. Evaluation of the impacted canine is carried out by tracing its axis and intersecting it with the perpendicular to Frankfurt's plane [26]. Various angles can be derived, whose significance from a prognostic point of view is as follows [ Readings under 10° are considered to be within the norm;…”

“…Among the 23 subjects recruited, 5 showed values included in the range 25°-45° and 1 an inclination > 45°. Finally, we evaluated the correlation between canine impaction, assessed according to the method described by Ericson and Kurol (11) and Orton (13), and the facial biotype according to McLaughlin's (MM: 28° ± 3°) cephalometric analysis (10). There was a prevalence of normodivergence (52%) and hypodivergence (32%), whereas only 16% of patients with impacted canines showed hyperdivergence.…”

“…Both the frequency and the complexity of treatment permit extensive study of possible interceptive approaches, with the aim to preventing a definitive impaction of the initially displaced canines. The aim of this study was to evaluate the existence of a statistically significant correlation between the facial biotype, measured according to the intermaxillary angle (MM) (10) and α angle (11), MM and β angle, (12) MM and the inclination of the upper cusp axis to the perpendicular-to-Fh plane (13), MM angle and distance "d" of the canine cusp to the occlusal plane (11).…”

Permanent maxillary canines are the second most frequently impacted teeth and the prevalence of this clinical condition is estimated to be 1-2% in the general population (1). Females are twice as frequently affected (1.17%) as males (0.51%) (2). This atypical limited eruption is most likely due to an extended tooth development period and to a long, difficult path of eruption because of anatomic limitations (3). Palatally displaced canines are three times more frequent than the buccal displacements (2). There are many possible etiologic factors associated with canine impaction. Bishara (4) lists the most common causes as the result of any one or a combination of the following factors: tooth size, arch length discrepancies, prolonged retention or early loss of the deciduous canine, abnormal position of the tooth bud, the presence of an alveolar cleft, ankylosis, cystic or SUMMARYPermanent maxillary canines are the second most frequently impacted teeth and the prevalence of this clinical condition is estimated to be 1-2% in the general population. The diagnosis of maxillary canine impaction should be based on both clinical and radiographic examinations. The aim of this study was to evaluate the presence of a correlation between the facial biotype and the inclination of the upper cusp axis. A correlation between the total radicular length of the lateral incisors was also evaluated, by comparing the side of impaction with the healthy side. Twenty three patients with a diagnosis of unilateral upper cusp impaction were recruited. For each patient, dental casts and radiographic material (panoramic radiographs and lateral cephalograms) were examined. Statistical analyses were done with Spearman's rank correlation coefficient or Spearman's rho (ρ). X-ray examinations demonstrated that canine impaction was associated to other dental anomalies (32% of the sample). The mean α angle measurements were 22.9° ± 4.1°, and mean values of the β angle were 34.7°± 4.0°. The mean distance "d" value was 14.6 mm ± 1.2 mm. The mean values of the angle between the upper cusp axis and the perpendicular-to-Fh plane were 20.8 °± 2.6°. Among the 23 subjects recruited, 5 showed values included in the range 25°-45° and 1 an inclination > 45°. The results obtained in the present study demonstrate a significant inverse correlation between the MM angle and the inclination of the upper cusp axis to the perpendicular-to-Fh plane.

“…Comme le précise Pajoni et al [12], le CT-scan ou le Dentascan, sans être des examens de première intention, doivent être prescrits lorsque les inclusions présentent des rapports radiculaires avec les dents adjacentes. Dans un souci de protection des patients face aux rayonnements ionisants, il est important de rappeler aux patients que les doses reçues au cours d'un CT-scan restent faibles, même comparées à celles de l'examen rétro-alvéolaire classique [11]. L'utilisation de la technique du volet osseux dans le déga-gement et l'avulsion de canines incluses apportent donc un net bénéfice aussi bien pour la cicatrisation à court terme que pour les possibilités thérapeutiques futures (entre autres implantaires).…”

Résumé -L'approche chirurgicale des canines incluses a été largement décrite. Les progrès de l'imagerie ont permis d'améliorer les techniques et de faciliter le choix de la voie d'abord. La chirurgie orale doit préserver les volumes osseux afin de ne pas hypothéquer une éventuelle chirurgie reconstructrice ou une réhabilitation prothétique. L'objectif de cet article est de décrire une alternative aux techniques actuelles dans la conservation des volumes osseux lors du dégagement ou de l'avulsion de canines incluses qu'elles soient maxillaires ou mandibulaires. Afin de combler le defect osseux et de limiter l'invagination de la muqueuse, certains auteurs proposent l'utilisation de biomatériaux, d'autres de greffe osseuse à partir d'un site donneur. Nous proposons la réalisation et le repositionnement d'un volet osseux, technique que nous présentons dans deux cas cliniques.Abstract -The surgical approach of included canins is well described. The techniques and the first surgical way moved on with the medical imagery progress. In oral surgery, one principle is to conserve bones volumes. In fact oral surgery should not spoil rehabilitation possibility by prosthesis or surgery reconstruction. The objective of this article is to describe a new way to preserve bone's volumes after a canin extraction even if it's maxillary or mandibular included. In purpose to fill the hole and to limit mucosa invagination, some authors use biomaterials and others prefer realise a bone autologous graft coming from another area. We suggest realization of a bone's part and repositioning secondary after tooth extraction. We present this technique in two clinic cases.
