This research intended to examine the morphometric relationship between the face and inverted maxillary central incisor in Malays and Chinese. 120 volunteers who met defined criteria participated in the study. Measurements were made directly and on digital images of each subject’s frontal facial view and the corresponding stone cast of the maxillary teeth. An image analyzer was used to divide t...

To evaluate the torque expression of right permanent maxillary central incisor with varying bracket positions and to compare same tooth different crown-root angulations. Finite Element Models Maxillary Central Incisor were used for simulation various angles. Three FEM models a angles (170˚,175˚,180˚, 165°) constructed heights subjected 30° labial root resultant expressions evaluated. The model ...

This is a case of delayed replantation of avulsed maxillary central incisor after an extended dry extra-alveolar period. A 10-year-old boy presented with avulsed maxillary central incisor after a fall that resulted in dental trauma, occurring 18 hours earlier. Treatment guidelines for avulsed mature permanent teeth with prolonged extraoral time were carried out for the teeth and the extraoral e...

This case report describes delayed replantation of an avulsed maxillary central incisor in a 17-year-old male patient following an injury on fall one day earlier. Avulsed maxillary right permanent central incisor was replanted back into the socket after extra-oral root canal treatment. One year follow up showed validity of treatment, with no evidence of resorption in the replanted tooth.

PURPOSE The purpose of this study was to compare the width ratio of maxillary anterior teeth according to age in the Korean population and to evaluate the maxillary central incisor width-to-length (W/L) ratio, given differences in age and gender. MATERIALS AND METHODS Ninety-three Korean adults were divided into 3 groups (n = 31) by age. Group I was 20 - 39 years old, Group II was 40 - 59 yea...

This case report aimed to present the course of surgically combined comprehensive orthodontic treatment a male adult with cleft lip and palate, showing left alveolar cleft, lateral deviation major segment maxilla, palatal transposition incisor. Preoperatively, midline upper central incisors was shifted by 7.0 mm right, right incisor showed transposition, residual 6.5 mm. Segmental Le Fort I ost...

Traumatic injuries to an immature permanent tooth may result in cessation of dentin deposition and root maturation. Endodontic treatment is often complicated in premature tooth with an uncertain prognosis. This article describes successful treatment of two traumatized maxillary central incisors with complicated crown fracture three months after trauma. The radiographic examination showed immatu...

A 10-year old Egyptian male presented with a geminated upper right central incisor along with a fused and rotated upper left central incisor in cross bite. He also had severe crowding in the maxillary arch and a congenitally missing lower right first permanent premolar. Orthodontic treatment was carried out to align upper right and left central incisors, lateral incisors, and canines. Treatment...

This research used the spectroradiometer (Pritchard Model 1980 B) to measure the spectral radiance factors of women's maxillary anterior teeth. The following conclusions were reached: 1. The spectral distributions of the anterior teeth were all similar at the cervical, middle, and incisal areas respectively. Their spectral distributions ran in parallel at an almost equal distance, with the curv...

Implant restorations have become a primary treatment option for the replacement of congenitally missing lateral incisors. The central incisor and canine often erupt in less than optimal positions adjacent to the edentulous lateral incisor space, and therefore preprosthetic orthodontic treatment is frequently required. Derotation of the central incisor and canine, space closure and correction of...
