CBCT images of 104 men and 104 women were divided into skeletal class I, II, and III malocclusion groups. Skeletal and dental evaluations were performed on the sagittal and axial cross-sections. One-w...
All cuspids were close to the labial bone cortex in different sagittal skeletal patterns and had different inclinations. There was a significant difference in the apical root position of cuspids in th...
Comparison of skeletal class I, II, and III malocclusion patients showed that dental compensation alleviated sagittal skeletal discrepancies in the cuspid positions of all patients, regardless of the ...
The article aims to design and develop a topology-optimized endosseous cuspid tooth implant of the maxilla region. The manuscript presents a numerical analysis of the resulting von Mises stresses and ...
The aim of the current study was to propose a classification of impacted cuspids, and bicuspids based on their spatial position in the maxillary and mandibular arches and their radiological appearance...
This prospective study was conducted including all the patients who reported to our center for extractions, orthodontic treatment, missing permanent cuspids/bicuspids, removal of third molar teeth. Al...
A total number of 4165 patients were enrolled in the study and based on the inclusion and exclusion criteria, 3680 patients were excluded and 487 patients with impacted cuspids/bicuspids were included...
The proposed clinical classification on impacted mandibular cuspids and bicuspids provides a structured approach to plan the treatment based on the 3-dimensional position of the teeth in the arch....
The long pathway that the canines take as they emerge into the maxillary arch makes them vulnerable to disruption during their natural emergence time. The process of planning treatment for impacted ma...
The aim of this article was to shed light on these complexities by discussing clinical case studies involving IMC, providing insights into the intricacies of their management....
The management of IMC within orthodontics presents a multifaceted challenge that include the necessity for precise diagnostic processes, prudent use of cone beam computed tomography (CBCT), the strate...
This 20-year retrospective study aimed to evaluate the treatment methods used in patients with impacted maxillary permanent canines and to determine the occurrence of ankylotic and resorptive processe...
The cohort consisted of 351 consecutive Caucasian patients (120 males and 231 females, mean age 18.4 and 19.9 years, respectively) with 420 impacted maxillary permanent canines. CT and CBCT findings w...
A total of 273 (65.0%) impacted canines were aligned in the dental arch by orthodontic traction after surgical exposure, this treatment was predominant in patients under 20 years of age. Surgical extr...
In conclusion, the treatment of impacted canines depends mainly on the age of the patient, and the position and inclination of the longitudinal axis of the impacted tooth. To select an adequate treatm...
Compare the efficacy of 2% lidocaine with adrenaline (1:200,000) and 4% articaine with adrenaline (1:100,000) in inferior alveolar nerve block prior to extraction of bilateral teeth posterior to canin...
Thirty-five patients were selected for the study. Patients were divided into two different groups: Group 1 - (2% lignocaine with adrenaline (1:200,000)) and Group 2 - (4% articaine with adrenaline (1:...
The difference in the efficacy of lignocaine and articaine was analysed using Student's t test. Within group comparison of the response to the pulp vitality test and VAS over various time periods was ...
Data analysis showed statistical differences in onset and depth of anaesthesia between the two groups (P < 0.05)....
4% Articaine with adrenaline (1:100,000) onset of action is faster and depth of anaesthesia is better compared to 2% lignocaine with adrenaline (1:200,000). Many previous studies reported onset of ana...
This study aimed to assess the accuracy of two different endodontic guides for fiber post removal....
In this in vitro study, 54 maxillary canine fiber posts were mounted on 36 maxillary stone casts; 18 teeth were mounted unilaterally, and 36 teeth were mounted bilaterally. Static endodontic guides we...
The mean MCD, MAD, and MAnD were 0.34 mm, 0.6 mm, and 2.32 degrees, respectively, in the SSG and 0.31 mm, 0.7 mm, and 2.37 degrees, respectively, in the DSG. The two groups were not significantly diff...
The accuracies of the two techniques, the extended double sleeve guide and the single sleeve guide, were comparable and thus DSG may be used for removal of fiber posts in adjacent or distant teeth....
This finite element study aimed to simulate maxillary canine movement during anterior teeth retraction....
Three methods of maxillary canine movement including miniscrew sliding with high hooks (MSH), miniscrew sliding with low hooks (MSL), and the traditional sliding method (TS) without using miniscrews w...
The distolingual tipping movements of the canine were shown in three movement modes. MSH showed a small tendency to lingual tipping movement and a extrusion movement while MSL had the largest lingual ...
The loss of tooth torque was inevitable, irrespective of which method was used to close the extraction space. However, miniscrew application and higher hooks reduced the loss of torque and avoided lin...
This study shows that miniscrew implants with different hooks can better control the movement of the maxillary canines. The non-invasive nature of the finite element analysis and its good simulation o...
This case report presents an orthodontic treatment conducted on a 13-year-old girl with bilateral Class II malocclusion and a mandibular impacted canine. The presence of an impacted tooth necessitates...
BACKGROUND This study aimed to evaluate the crown length and width and root length and dilacerations in unilateral impacted maxillary canines, compared with contralateral erupted canines, and to inves...
