Background Lots of studies on maxillary anterior teeth proportions have been studied in different populations in various countries, but no studies have been conducted in Nepal on the esthetic maxillary anterior teeth proportions. Objective The study was done to investigate the maxillary anterior teeth proportions in a Nepalese population. Teeth proportions in the total population were compared ...

INTRODUCTION Our objective was to determine the short-term skeletal and dental effects of the Xbow appliance when compared with an equivalent untreated control group as measured on lateral cephalograms. METHODS A prospective sample of 69 consecutive Class II patients treated with only the Xbow appliance was compared with 30 historical Class II untreated controls. Standardized lateral cephalog...

A ten year old boy came with a chief complaint of unerupted permanent maxillary right central incisor. Deciduous right central and lateral incisors were retained. Radiographic examination revealed an inverted and dilacerated mesiodens with the root bent over the incisal surface of the right central incisor preventing its eruption. An occlusal radiograph and radiographs using shift cone techniqu...

Objective: To assess and evaluate the tip, torque, slot size & slot distortion of maxillary central incisor, maxillary lateral incisor & maxillary canine brackets from commercially available bracket systems (Agile Mini Brackets3M series, Mini seriesAmerican Orthodontics, Mini Gem seriesDento Smile, Fine Series Brackets Galaxy Orthodontics, Centrino Mini bracketsLibral trader, Orthox Organizers)...

BACKGROUND A facial bone (<2 mm) overlying maxillary anterior teeth may be prone to resorptive processes after extraction and immediate implant placement. A thin bone contributes to risk of bone fenestration, dehiscence, and soft-tissue recession. This study measures the distance between the cemento-enamel junction (CEJ) and alveolar bone crest and the thickness of facial alveolar bone at point...

Aim: To investigate the incisor wingings of the Southern Chinese and compare these with studies in different populations. Materials and Methods: The maxillary and mandibular incisor alignment in study casts of an unselected sample from a 12 year old Hong Kong Oral Health Survey of 12 year old children (n=459; 295 boys and 164 girls) were studied. Results: The prevalence of bilateral winging in ...

OBJECTIVE This study aimed to propose clinical guidelines for placing miniscrew implants using the results obtained from 3-dimensional analysis of maxillary anterior interdental alveolar bone by cone-beam computed tomography (CBCT). METHODS By using CBCT data from 52 adult patients (17 men and 35 women; mean age, 27.9 years), alveolar bone were measured in 3 regions: between the maxillary cen...

Purpose: To establish a new coordinate system using the incisive canal and incisive foramen in cases confirmed to have root resorption in the maxillary incisor region by cone beam computed tomography (CBCT) to investigate the positions of the central and lateral incisor roots and erupting maxillary canine tooth crowns in the horizontal plane. Methods: Nine patients (two males; mean age: 10.5 ye...

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 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...
