OBJECTIVE: To establish whether a correlation exists between the innercanthal width and maxillary central incisors. STUDY DESIGN: A Descriptive cross sectional study PLACE AND DURATION: Department of Prosthodontics, Dr Ishrat ul Ebad Khan Institute of Oral Health Sciences, Dow University of th th Health Sciences Karachi and from 15 October 2012 to 25 March 2014. METHODOLOGY: One hundred and sev...

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...

To provide an anatomical basis for clinical implant esthetics, we evaluated the morphology of the nasopalatine canal (NPC) and analyzed labial and interproximal bone anatomy at the maxillary anterior region. We sought to investigate the effect of maxillary protrusion and tooth labiolingual inclination on labial bone anatomy in Chinese adults. Three dimensional (3D) images were reconstructed usi...

This article reports a clinical case of a 13-year-old girl, who was referred with chief complaint of a non-esthetic maxillary central incisors position. Five years ago, her maxillary right and left central incisors and left lateral incisor intruded into the maxilla. The intruded teeth were splinted for a month. After splint removal, the patient lost follow up. The aim of this work is to report ...

Molar-incisor malformation (MIM) or molar root-incisor (MRIM) is a dental anomaly that affects teeth and maxillary central incisors. Even though, the etiology not exactly known, it has been reported several factors such as staphylococcal infection in neonatal period, neurological diseases meningitis hydrocephalus, ongoing medications, infectious premature delivery were effective. In this case r...

in this investigation the thickness of enamel in the gingival, middle, and incisal thirds of the labial surface of the anterior teeth were measured regarding preparation of the teeth for porcelain laminate veneers.part one, 20 extracted intact human maxillary central and lateral incisors ten of each were selected. the teeth were imbedded in autopolimerize acrylic resin. cross section was prefor...

The term “impacted teeth” refers to dentition that is partly or completely impacted in bone or soft tissue after eruption should have been completed although eruption age is completed not replaced in dental arc. The most commonly impacted teeth in the anterior region are maxillary canines, while the prevalence of impacted maxillary incisors ranges from 0.06% to 0.2%. Impacted maxillary incisors...

When dental implants are malpositioned in relation to the adjacent teeth and alveolar bone or in an excessive buccal or lingual position, the final prosthesis rehabilitation impairs the peri-implant health of the gingival tissues and the aesthetics of the patient. Thus, the purpose of this case was to report and discuss a multidisciplinary protocol for the treatment of a compromised maxillary t...

The maxillary lateral incisor is the second most common congenitally absent tooth. There are several treatment options for replacing the missing maxillary lateral incisor, including canine substitution, tooth-supported restoration, or single-tooth implant. Dental implants are an appropriate treatment option for replacing missing maxillary lateral incisor teeth in adolescents when their dental a...

AIM This finite element study was conducted to calculate the distribution of stresses in the periodontal ligament when various orthodontic forces were applied, with emphasis on the effect on root apex. MATERIALS AND METHODS An in vitro finite element method was used to construct a three-dimensional finite element model of a maxillary central incisor, its periodontal ligament and alveolar bone...
