New insights on age‐related association between nasopharyngeal airway clearance and facial morphology Orthod Craniofac Res 2012; 15 :188–197. © 2012 John Wiley & Sons A/S Structured Abstract Objectives – To evaluate the relation adenoid hypertrophy across age in a pediatric population. Setting Sample Population The American University of Beirut Department Otolaryngology. Two‐hundred consecutive children (age 6.00 ± 2.62 years) referred from...
To evaluate the association between soft tissue at chin (STC) thickness and mandibular divergence.Nongrowing patients seeking orthodontic treatment (n = 190; 113 women 77 men), who had an average age of 26.94 years (range 18.10-53.50 years), were stratified in four subgroups based on cephalometric plane inclination to anterior cranial base (MP/SN): low MP/SN ≤ 27° 48); medium-low < 32° 60); medium-high 37° 37); high ≥ 45). The STC thicknesses measured pogonion (Pog), gnathion (Gn), menton...
The alignment of craniofacial structures in three dimensions-transverse, vertical, and sagittal-determines facial esthetics. While skeletal dental factors influence these outcomes, soft tissue characteristics, especially (FST) thickness, are increasingly recognized as important. However, few studies have examined the impact vertical divergence on variation, particularly middle lower thirds face. This study aimed to evaluate association between characteristics upper adult patients. A total...
Background: The segmentation of individual teeth in three-dimensional (3D) dental models is a key step orthodontic computer-aided design systems. Traditional methods lack robustness when handling challenging cases such as missing or misaligned teeth. Objectives: to semantically segment maxillary and palatal rugae 3D textured scans using Convolutional Neural Networks (CNNs) assess tooth movement after treatment stable references. Methods: Building on the two-dimensional image semantic...
Existing evidence on changes of the palatal rugae following rapid maxillary expansion (RME) is scarce and inconclusive, particularly immediate post-expansion in three-dimensional assessments.Our aims were to assess dimensional stability antero-posterior transverse dimensions RME treatment, as well volume area.The sample consisted dental casts 30 adolescents (16 males; 14 females, age 11.46 ± 1.42 years) who underwent RME. The models, available at T1 (pretreatment) T2 (immediately after...
<h3>Objective</h3> To evaluate the correlation between and significance of 2 methods palatal airway assessment on lateral cephalographs. <h3>Design</h3> Diagnostic cephalometric imaging study that took place from January 1, 2006, to December 31, 2007. <h3>Setting</h3> American University Beirut Medical Center. <h3>Patients</h3> Children with chronic mouth breathing referred by a pediatric otolaryngologist for evaluation participating orthodontists. <h3>Main Outcome Measures</h3> Two...
The aim of this study was to evaluate the inclination maxillary incisors (I), facial axis (FA), and growth (GA) in different vertical sagittal patterns.
The superimposition of sequential radiographs the head is commonly used to determine amount and direction orthodontic tooth movement. A harmless method includes timely unlimited on relatively stable palatal rugae, but performed manually and, if automated, relies best fit surfaces, not only rugal structures. In first step, motion estimation requires segmenting detecting location teeth rugae at any time during intervention. Aim: develop a process segmentation that eliminates all manual steps...
ABSTRACT Objectives: To evaluate the association between maxillary arch dimensions and fundamental frequency formants of voice in prepubertal subjects. Materials Methods: Thirty-five consecutive patients seeking orthodontic treatment were recruited (mean age = 11.41 ± 1.46 years; range, 8 to 13.7 years). Participants with a history respiratory infection, laryngeal manipulation, dysphonia, congenital facial malformations, or excluded. Dental measurements included length, perimeter, depth,...
