objective: implants are being used in orthodontics as a reliable mode of anchorage. among other factors, the cortical bone thickness plays a major role in determining the stability of these implants. the objective of this study was to study the relationship of various arch forms and the cortical bone thickness and to determine if the cortical bone thickness varies between various arch forms. th...

The interaction between tongue size/volume and craniofacial skeletal growth is essential for understanding the mechanism of specific types of malocclusion and objectively measuring outcomes of various surgical and/or orthodontic treatments. Currently available information on this interaction is limited. This study was designed to examine how tongue body volume reduction affects craniofacial ske...

AIM. This paper is an attempt to compare and analyze the various mathematical models for defining the dental arch curvature of children in normal occlusion based upon a review of available literature. Background. While various studies have touched upon ways to cure or prevent dental diseases and upon surgical ways for teeth reconstitution to correct teeth anomalies during childhood, a substanti...

The aims of this study were to evaluate the effectiveness of a lower lingual holding arch (LLHA) in maintaining arch length, and to compare the effectiveness of two LLHAs made of two different gauges (0.9 and 1.25 mm) of stainless steel (SS) wire. The sample comprised 44 subjects (24 males and 20 females) who for various reasons attended orthodontic clinics at Jordan University of Science and T...

for treating an impacted, dilacerated maxillary central incisor in the mixed dentition. A new fixed appliance promotes proper sagittal and vertical traction of the incisor into the dental arch, while maintaining the patient’s periodontal health and preserving root length. The appliance is an .040" stainless steel fixed lingual arch, soldered to the lingual surfaces of the maxillary first molar ...

OBJECTIVE To determine the most common maxillary and mandibular arch form and size in primary dentition stage. MATERIAL AND METHODS Four hundred thirty five preschool children were included in this study with an age range of 3.5-5.5 years old. Dental casts were digitized and landmarks for the measurements were identified and marked on each model. Ten points were determined on the dental arch....

AIM To analyze the interrelationship between incisor width, deviations in the dentition and available space in the dental arch in palatally and labially located maxillary ectopic canine cases. MATERIALS AND METHODS Size: On dental casts from 69 patients (mean age 13 years 6 months) the mesiodistal widths of each premolar, canine and incisor were measured and compared with normal standards. De...
