Macrodontia is a rare dental anomaly which consists on the presence of any tooth or teeth larger than the average. In the present report the case of a child with an uncommon true isolated macrodontia of a maxillary central incisor is presented. The maxillary left central incisor was considered a macrodontic tooth since its mesiodistal crown dimension was 12.41 mm while the mesiodistal crown dim...
AIM The purpose of this case report is to describe the combined surgical and orthodontic treatment of two cases with an impacted maxillary central incisor and canine in the same quadrant and to discuss the causal relationship between them. BACKGROUND The most common causes of canine impactions are usually the result of one or more factors such as a long path of eruption, tooth size-arch lengt...
BACKGROUND Implants have been widely used to restore missing teeth. Limited information on applied anatomy at the anterior maxilla compromises the clinical outcome for implant placement in this region. In the current study, Cone Beam Computerized Tomography (CBCT) was used to measure alveolar ridge and buccal undercut dimension at the anterior maxilla to help develop treatment planning for imme...
Dental trauma is a challenge for dental integrity and can lead to pulp necrosis. The clinical case reports the diagnosis of a maxillary right central incisor traumatized and its multidisciplinary treatment. Calcium hydroxide material was used to perform the processing apexification. An apical surgery was carried out to remove the apical periodontitis and to return the aesthetics to the patient;...
Permanent mandibular central incisor is rarely affected by tooth shape anomalies of crown and root. Co-occurrence of multiple anomalies in a permanent mandibular central incisor is extremely rare. This paper reports an unusual concurrent combination of multiple dental anomalies affecting both the crown and root of a permanent mandibular left central incisor - talon cusp, dens invaginatus, short...
The purpose of this study was to determine the severity of gingival margin discrepancy affecting the mandibular incisors in children with a single-tooth anterior crossbite. The response of the position of the gingival margin to correction of the crossbite also was investigated. Twenty-two subjects with a single central crossbite and 16 subjects with a single lateral crossbite were identified fr...
The aim of the retrospective study was to evaluate the influence of the initial vertical position of the impacted maxillary incisor on spontaneous eruption frequency and timing after surgical removal of the supernumerary tooth. Records of 33 patients with unilateral impaction of upper central incisor caused by supernumerary teeth with the average age 9.58+/-1.54 years were analyzed. Impacted te...
BACKGROUND This article describes the management of a complicated crown root fracture. CASE REPORT A young patient presented with a crown root fracture of the maxillary left central incisor with an oblique subgingival fracture line. A multidisciplinary treatment approach including endodontic treatment, orthodontic extrusion, surgical extraction and intra-alveolar repositioning was used to gai...
the aim of this case report was to introduce an appliance for correcting severe rotation of anterior teeth in the mixed dentition period. a 9-year-old iranian boy with a mixed dentition class i malocclusion complained of a severely rotated of upper right central incisor. there was a mesiodens between the central incisors. the supernumerary tooth was first extracted and then a whip appliance whi...
Objective: The aim of present study was to investigate the difference of torque control during intrusion force in incisors with normal, under and over-torque in lingual and labial orthodontic systems through finite element analysis. Material and Methods: 3D models of an upper right central incisor with different torques were designed in Solid Works 2006.The models were transferred to the ANSYS ...
