BACKGROUND The benefits of breastfeeding on oral health are still inconclusive, especially the association on occlusion. This study aimed to investigate the association of breastfeeding and the development of primary dentition. METHODS A cross-sectional study was conducted with 851 Asian children aged 2-5 years old in Hong Kong. Questionnaires were completed by the parents to collect informat...

The fundamental factors in the diagnosis in the orthodontic treatment are the spacing condition, tooth size, arch form and its dimensions. Plaster model analysis is a time-consuming procedure. Dividers, calipers, and Boley gauges have provided the standart of measurement against which newer methods have been evaluated [1]. Various scanning techniques, including laser scans, structured light, de...

statement of the problem: the stability of orthodontic treatment depends on preserving the patient’s pretreatment arch form and arch size during and after treatment. purpose: this investigation was aimed to study the size and shape of iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...

Background: Rapid maxillary expansion (RME) is a dentofacial orthopedic treatment often used to treat patients with narrow palate and transverse growth deficiency. Introduction: This leads correction of posterior dental crossbites, coordination the upper lower arches gaining arch perimeter in tooth size/arch size discrepancies. To stabilize results obtained RME limit or avoid relapse, use Trans...

intra-oral appliances such as transpalatal arch and nance appliance fail to resist against forces that tend to loosen the anchorage. the infirmity arises due to the long lever arm and the mesial force that is perpendicular to the long axis of the appliance. the butterfly arch is presented here as an intra-oral appliance that withstands the mesially directed forces with a mechanism that puts str...

The purpose of this study was to compare the dentofacial effects of two intraoral molar distalization techniques [three-dimensional bimetric maxillary distalization arches (3D-BMDA) and a modified Begg intraoral distalization system (MBIDS)] in subjects requiring maxillary molar distalization. Twenty-one patients (12 females and 9 males, mean age pre-treatment: 14.7 +/- 1.50 years) were treated...

Although the existence of a relationship between crown size and body size has previously been questioned 'S. M. GARN, and A. B. LEWIS, Amer Anthrop 60:894-880, 1958; H. A. BAILIT and J. S. FRIEDLAENDER, Amer Anthrop 68:665672, 1966), recent studies show that there are systematic, positive, but low-order, correlations between crown size and various body dimensions (R. FILIPSSON and L. GOLDSON, A...

Aim: This case report aims to illustrate a clinical protocol that allows for the rehabilitation of patients requiring extensive osteotomy, simultaneous implant placement, and full-arch, screwed-in prosthetics in one session. improvement aesthetics functionality fixed implant-supported prosthesis through preoperative planning all surgical procedures, including application 3D-printing technology ...
