OBJECTIVE To compare the anchorage effects of the implants and the headgear for patients with anterior teeth retraction in terms of incisor retraction, anchorage loss, inclination of maxillary incisors, positional change of maxillary basal bone, and treatment duration. MATERIALS AND METHODS An electronic search for relative randomized controlled trials (RCTs) prospective and retrospective con...

the success of endodontic therapy requires knowledge of the internal and external dental anatomy and its variations in presentation. this case report involves endodontic treatment of a traumatized maxillary central incisor with two separate roots.

Transposition may affect both sexes equally and, although it may occur in the maxilla or in the mandible, the frequency of maxillary permanent canine involvement is the greatest [3]. In the maxilla the canine is transposed most frequently with the first premolar (Figure 1a,b), less often with the lateral incisor followed rarely by central incisor or second premolar In the mandible transposition...

AIM To report a maxillary central incisor tooth with a horizontal root fracture and incomplete root development that healed and was then moved orthodontically some years after the traumatic injury. SUMMARY A 7-year-old girl attended following trauma to the maxillary anterior region. Radiologic examination revealed a horizontal root fracture in the middle third of the maxillary right central i...

BACKGROUND Different crown-root angulations of maxillary central incisors can be assumed as a potential reason for many underscored outcomes of orthodontic treatments. The aim of this study was to determine the effects of the different crown-root angles on stress distributions in the maxillary central incisor's periodontal ligament (PDL) during application of intrusive and retraction forces usi...

A method of recording incisor inclination is described using the Tooth inclination Protractor (TIP). This instrument was used to record incisor inclination on dental casts. The scores were related to traditionally determined inclinations for the upper incisor to maxillary plane and the lower incisor to mandibular plane from the lateral cephalometric radiograph. The TIP scores were closely relat...

Talon cusp is an uncommon anomaly, whose etiology may be disturbances in the morphodifferentiation stage. Dens in dente is also a rare anomaly that is challenging in clinic as it may cause pulp necrosis or periapical lesions due to the communication with the oral cavity. This article reports multiple talon cusps on permanent maxillary and mandibular incisors and molars in 3 siblings. A 9-year-o...

for treating an impacted, dilacerated maxillary central incisor in the mixed dentition. A new fixed appliance promotes proper sagittal and vertical traction of the incisor into the dental arch, while maintaining the patient’s periodontal health and preserving root length. The appliance is an .040" stainless steel fixed lingual arch, soldered to the lingual surfaces of the maxillary first molar ...
