In an effort to identify the frequency and differences in the dental and skeletal components of a large sample of adults with Class III malocclusion, with and without open bite, 176 subjects, one half of whom had an anterior open bite, were evaluated. These subjects were chosen by looking at the lateral cephalometric radiographs that were taken of 302 adults (128 men and 174 women) who exhibite...
Objective: An immediate complete denture is fabricated before the extraction of all teeth. It has several advantages such as preservation of esthetics, muscular tone, normal speech and reduction of post-operative pain. This report describes a method of using patient’s current fixed partial denture (FPD) for single-appointment construction of interim immediate denture. Case: We used patient’s ex...
The goal of this study was to analyse the effect of growth hormone (GH) on catch-up growth of functional facial (splanchnocranial) and neurocranial components in rats with intrauterine growth retardation (IUGR). Wistar rats were divided into the following groups: control (C), sham-operated (SH), IUGR, and IUGR + GH. IUGR was surgically induced and GH was administered between 21 and 60 days of a...
BACKGROUND Mouth breathing may affect facial form and the positions of the teeth. OBJECTIVES To determine whether the increased dentoalveolar and facial heights found in mouth breathing children with enlarged adenoids are maintained following adenoidectomy and changed mode of breathing from mouth to nose. METHODS The subjects were Swedish children, either mouth breathers with nasal obstruct...
There is a large controversy about the causal relations between dento-facial deformities and mouth-breathing habits. Some postural and morphological changes during long-term adaptation to oral respiration are evoked: opening of the bite with a lowered postural position of the mandible, reduction of upper arch width, downward and backward rotation of the mandible, increased lower facial height a...
A spheno – occipital synchondrosis is a cartilaginous joint, a growth centre found in the base of the skull between the basilar part of the occipital bone and the body of the sphenoid bone joining them together with a hyaline cartilage. This joint is important in cranio facial development for both vertical axis and horizontal plains resulting in the increase of facial height and width. The hyal...
BACKGROUND It is impossible to give an objective anthropologic assessment of the overall physical development of a child's body during the time of intensive growth (7-17 years) without taking into account the age and gender changes in the absolute and relative head and face measurements. Head growth has specific characteristics that makes it different from the growth of other parts of the body....
statement of the problem: achieving a normal soft tissue facial profile is considered to be the main concern of class iii patients and the goal of most class iii treatments. purpose: the purpose of this study was to investigate the effects of facemask treatment on profile with photogrammetric method. materials and method: before (t0) and after (t1) treatment photograms of 40 class iii patients ...
INTRODUCTION Orthodontic mini-implants have been incorporated into orthodontic treatment modalities. Adequate bone at mini-implant placement site can influence the success or failure of anchorage. The present study was to determine the thickness of cortical bone in the maxillary mid-palatal area at predetermined points for the placement of orthodontic mini-implants using Cone Beam CT technique ...
When anthropometric methods were introduced into clinical practice to quantify changes in the craniofacial framework, features distinguishing various races/ethnic groups were discovered. To treat congenital or post-traumatic facial disfigurements in members of these groups successfully, surgeons require access to craniofacial databases based on accurate anthropometric measurements. Normative da...
