prevalence of Maxillary Canine impaction in skeletal class iii malocclusions compared to class i malocclusions
Journal of Clinical and Experimental Dentistry, 2019Co-Authors: Gabriele Di Carlo, Matteo Saccucci, Valeria Luzzi, Gaetano Ierardo, Iole Vozza, Gianluca Sfasciotti, Antonella PolimeniAbstract:Background The aim of the present investigation was to evaluate if an orthodontic population of Class III malocclusion patients shows a different prevalence of Maxillary Canine impaction than Class I subjects. Material and methods Fifty-eight subjects were retrospectively selected and assigned to the Class I group (n= 32) or the Class III group (n= 26), depending on the ANB and WITS values. Lateral cephalograms were used to collect angular and linear measurements that described the skeletal and dental Maxillary features of the subjects, while orthopantomography was used to assess the impaction or the correct eruption of the Maxillary Canines. An independent samples T-test or a Mann-Whitney U-test was used to compare the cephalometric values between the two groups, while a chi-squared test was used to evaluate the distribution of Maxillary Canine impaction between the two groups. Results No statistically significant difference was found for the cephalometric variables, and the frequency of Canine impaction showed no difference between the Class III and Class I subjects. Conclusions Patients with skeletal Class III malocclusions did not show a different prevalence of Canine impaction; therefore, such skeletal features cannot be used as a diagnostic aid for assessment of the risk of Maxillary Canine impaction. Key words:Skeletal Class III, Angle Class III, Maxillary Canine impaction, tooth impaction.

the sequential hypothesis of impaction of Maxillary Canine a hypothesis based on clinical and radiographic findings
Journal of Cranio-maxillofacial Surgery, 2012Co-Authors: Anand K. Sajnani, N M KingAbstract:The aetiology of impacted Maxillary Canines remains obscure. Numerous researchers have focused on identifying specific and non-specific aetiological factors responsible for Canine displacement. Currently, the two most popular hypotheses that have gained consensus worldwide are the guidance theory and the genetic theory. However, no single hypotheses, can completely explain the aetiology of impaction of Maxillary Canines. This retrospective study was used to develop and postulate the aetiology of both buccally and palatally impacted Maxillary Canines. The study was conducted on a sample of 533 patients for whom the pattern and distribution of the impacted Maxillary Canines, sex differences, the dental age of the patients, dental anomalies and various geometric measurements which were made on the panoramic radiographs were recorded. Based on these findings, the sequential hypothesis of impaction of the Maxillary Canine was postulated. The hypothesis states that both buccally and palatally impacted Canines have similar aetiological factors leading to their impaction. It is suggested that genetic mechanisms strongly influence the potential of the Maxillary Canine to be impacted and the guidance from the lateral incisor and the stage of development plays a vital role in determining the ultimate position of the impacted Canine.

Early prediction of Maxillary Canine impaction from panoramic radiographs.
American journal of orthodontics and dentofacial orthopedics : official publication of the American Association of Orthodontists its constituent socie, 2012Co-Authors: Anand K. Sajnani, Nigel M. KingAbstract:Introduction Treatment of impacted Maxillary Canines frequently requires surgical intervention, which can involve substantial complications. Thus, it is desirable to identify a reliable method for the early diagnosis of Canine displacement. In this study, we sought to determine whether impaction of a Maxillary Canine can be predicted using measurements made on a panoramic radiograph. Methods This retrospective study was conducted at a dental hospital in Hong Kong with panoramic radiographs. Geometric measurements were made on 384 panoramic radiographs of patients with a unilaterally impacted Maxillary Canine (group I) to characterize its presentation and compare them with the unaffected antimere (group II). Results There was a clinically discernible difference of 4 mm at the age of 8 years and beyond between the mean distance of the tip of the impacted Canine (group I) and that of the antimere (group II) from the occlusal plane (P Conclusions Diagnosis of Maxillary Canine impaction is possible at 8 years of age by using geometric measurements on panoramic radiographs.
