ABSTRACT Objectives: To determine an optimal anteroposterior (AP) position of the maxillary central incisors and their relationship to the forehead in adult African American (AA) females. Materials and Methods: Smile profile photographs of 150 AA females were acquired and divided into an optimal control group (N = 48) and a study group (N = 102) based on the position of the maxillary central incisors, as judged by a panel of orthodontists and orthodontic residents. The AP position of the maxillary central incisors and the forehead inclination (FI) were measured relative to Glabella vertical (G

Abstract Objective: To investigate the impact of a persisting high lip line and other potential relapse-inducing factors on long-term stability of orthodontic correction of retroinclined maxillary central incisors. Materials and Methods: Thirty-one cover-bite (“Deckbiss”) patients with retroinclined maxillary central incisors and a deep frontal overbite were evaluated. The maxillary central incisor inclination was determined odontometrically with study models made pretreatment, posttreatment, and at a follow-up examination (mean posttherapeutic interval: 9.0 years).

Abstract:

Dental agenesis of the maxillary lateral incisor is a frequently seen anomaly in children and teenagers nowadays. It can alter the esthetics as well as the functions in the frontal area of the maxilla and therefore, early detection and therapy would be beneficial. The treatment often implies an interdisciplinary approach between orthodontics and implantology. One of the particularities of this kind of treatment is given by the distal angulation of central incisor’s root, which invades the space required by the dental implant. Any treatment plan should begin with a thorough radiographical analy

Clinically, supernumerary teeth are able to cause different local disorders and the most common one is impaction of maxillary incisors. Impacted maxillary incisors substantially affect esthetics, function, and self‑esteem of patients. Impaction of maxillary permanent incisor is a rare clinical entity in dental practice. Although impaction of a permanent tooth is rarely diagnosed during the mixed dentition period, an impacted central incisor is usually diagnosed accurately when there is delay in the eruption of tooth. Multiple treatment options are available for impacted incisors. Surgical-orth

Abstract:

Aims: The aim of this study was to retrospectively compare the morphometrics of permanent maxillary central incisors with and without eruption disturbances, while simultaneously evaluating prognosis based on different factors. Materials and Methods: Seventy patients with unilateral permanent maxillary central incisor eruption disturbances were included. Within a group of 70 subjects, measurements were taken for both normally erupted central incisors and central incisors with eruption disturbances to determine the length of the roots and the volume of the teeth. Various factors, such as angulat

Introduction: A true maxillary intrusion is always a challenge for orthodontists. There are number of methods of incisor intrusion. Mini Implant assisted incisor intrusion is gaining popularity in recent years.

Abstract:

Age estimation using the radiographic method is a simple and non-invasive method that is suitable for age estimation because it can provide information about tooth maturity and morphological changes related to increasing age and is feasible to do in both living and dead persons. The maxillary central incisor teeth are selected for age estimation because it has a single root, large pulp and tends to present in old age. This study aimed to estimate age based on the Kvaal method on the maxillary central incisors using dental radiographs. This is an analytic observational study using 46 samples of

Traumatic injuries are widespread in children in the younger age group. An avulsion is a type of dental trauma in which complete dislodgment of the teeth occurs from the respective socket. The primary maxillary central incisors are the most common teeth to be avulsed, followed by maxillary lateral incisors and the Primary mandibular central incisors. We present this case because of the unusual avulsion of a primary mandibular central incisor due to a freak accident by accidental engagement of father s ring in the child’s tooth while playing with her.

Braces were placed on the first molars and the maxillary central incisors. The biomechanics of the anchors on the first molars elicited substantial mesial movement of the left central incisor to match the midline.
