• occlusion
  • A major disadvantage of classifying malocclusions according to Angle's system is that it only takes into consideration the two-dimensional viewing along a spatial axis in the sagittal plane in the terminal occlusion, even though occlusion problems are, in principle, three-dimensional. (wikipedia.org)
  • The way that the jaws, and thus the dental arches, approach each other when the mouth closes, which is called the occlusion, determines the occlusal relationship of opposing teeth, and it is subject to malocclusion (such as crossbite) if facial or dental development was imperfect. (wikipedia.org)
  • cleft
  • Malocclusion Cleft lip and palate Macroglossia Ankyloglossia Stafne defect Torus palatinus Torus mandibularis Eagle syndrome Bacterial (Plaque-induced) gingivitis-A common periodontal (gum) disease is Gingivitis. (wikipedia.org)
  • Some most notable indications for the need of a palatal expander include: Posterior cross bite Crowding of the teeth Most cases of malocclusion Rhinologic and respiratory ailments Impacted maxillary canine Cleft lip Cleft palate Rapid palatal expansion (RPE) or Rapid Maxillary Expansion (RME) is an expansion technique where expansion of 0.5mm to 1mm is achieved each day until the posterior crossbite is relieved.

  • dental
  • Physical examination may also reveal evidence of lip licking, drooling, or an anatomical predisposition to the condition, such as dental malocclusion or poorly-fitting dentures, which result in overlap of the upper and lower lips. (psychiatryadvisor.com)
  • In humans and many other species, the superior (maxillary or upper) dental arch is slightly larger than the inferior (mandibular or lower) arch, so that in the normal condition the teeth in the maxilla (upper jaw) slightly overlap those of the mandible (lower jaw) both in front and at the sides. (wikipedia.org)
  • Individual differences in dental structure, lip shape and size, jaw shape and the degree of jaw malocclusion, and other anatomical factors will affect whether a particular embouchure technique will be effective or not. (wikipedia.org)
  • In humans, hypomorphic mutations (partial loss of gene function) in the ATR gene are linked to Seckel syndrome, a condition characterized by proportionate dwarfism, developmental delay, marked microcephaly, dental malocclusion and thoracic kyphosis. (wikipedia.org)
  • indices
  • Other indices of this type score tooth alignment in a way that allows study of tooth irregularity and periodontal disease, or treatment stability Eg: Epidemiologic registration of malocclusion by Bjork, Krebs, and Solow The FDI method Summer's occlusal index. (slideshare.net)
  • Treatment need (treatment priority) indices Allow categorization of malocclusion according to the level of treatment need. (slideshare.net)
  • upper
  • Prominent upper incisors may be a target for teasing and bullying and it is now accepted that one reason for undertaking treatment of malocclusion is the psychosocial benefit that it accrues. (wikipedia.org)
