This systematic review evaluates long-term dental arch changes after rapid maxillary expansion treatment on orthodontic patients with constricted arches. Clinical trials that assessed dental arch changes through measurements on dental casts or cephalometric radiographs were selected. No patients with surgical or other simultaneous treatment during the active expansion period were accepted. Elec...

BACKGROUND AND AIM: Existence of developmental spaces during the primary dentition period is essential for the permanent dentition period and results in regular eruption of permanent teeth. The wide class of different occlusion and dental arch types during the primary dentition period, based on factors such as race, conducted to research the prevalence of these...

This study was designed to clarify the three dimensional features of naso-maxillary complex in cleft lip and palate (CLP) by using computed tomography (CT) and to examine its change following an upper dental arch expansion. Sequential CT images with 2mm-thickness were obtained for 11 unilateral CLP boys (UCLP), 6 bilateral CLP boys (BCLP) and 4 boys without cleft (non-cleft). Additionally, two ...

INTRODUCTION This study aims to determine the shape and dimension of dental arches from a lingual perspective, and determine shape and size of a straight archwire used for lingual Orthodontics. METHODS The study sample comprised 70 Caucasian Brazilian individuals with normal occlusion and at least four of Andrew's six keys. Maxillary and mandibular dental casts were digitized (3D) and the ima...

BACKGROUND Aesthetic tooth selection and physiological tooth arrangement are the objectives of the complete denture fabrications. The objective of this study was to determine the relationship of the intercondylar width with mandibular inter-canine width. METHODS This cross-sectional comparative study was conducted in Department of Prosthodontics, Lahore Medical and Dental College, Lahore from...

This case report describes a new surgical orthodontic approach involving alveolar bone distraction osteogenesis for correction of an asymmetric maxillary dental arch. The treatment was combined with conventional orthognathic surgery to improve the mandibular lateral deviation. This new treatment strategy produced an ideal dental arch and a symmetric facial appearance efficiently and effectively.

BACKGROUND Plaster casts of individual patients are important for orthodontic specialists during the treatment process and their analysis is still a standard diagnostical tool. But the growing capabilities of information technology enable their replacement by digital models obtained by complex scanning systems. METHOD This paper presents the possibility of using a digital camera as a simple i...

Objective: To highlight the advantages and disadvantages of the concept of shortened dental arch in the rehabilitation of a dentition with conventional and implant supported prosthesis, expanding treatment options to patients. Literature review: The traditional restorative concept makes the dentition a cycle of permanent repair, more than 50% of the restorative treatments consists on the repair...

Open mouth posture and maxillary arch width were assessed annually for 4 years in a group of children. While younger children exhibited high levels of open mouth posture, this behavior decreased significantly over time. Racial and sex differences, as well as a race-by-time interaction were also evident. The children displayed a significant increase in maxillary arch width across time with sex a...

Objectives: In recent years, substantial effort has been evident in the field of mathematical analysis of the dental arch curve, particularly of children from varied age groups and diverse ethnic and national origins. Many eminent authors have put forth mathematical models to describe the teeth arch curve in humans. Each such model had advantages and disadvantages, but none could exactly define...
