Dofka Chapter 15 orthodontics Dental Terminology

• orthodontia


  study dealing with the prevention and correction of abnormally positioned or misaligned teeth
• orthodontist


  graduate dental student who has completed an additional two to three years of study in orthodontics
• centric relationship


  the most retruded position of the mandibular condyle into the glenoid fossa
• distoclusion


  class II condition in which the mesiobuccal cusp of the maxillary first molar is anterior to the buccal groove of the mandibular first molar
• division 1


  maxillary incisors protruding with a v-shaped arch instead of a u shaped arch
• division 2


  maxillary incisors having a lingual incline with an excessive overbite and a wider than normal arch
• mesioclusion


  class III condition, in which the mesiobuccal cusp of the maxillary first molar occludes in the interdental space of the mandibular permanent first molars distal cusp and the mesial cusp of the mandibular permanent second molar
• mesioversion


  tooth is positioned more mesial than normal
• distoversion


  tooth is positioned more distal than normal
• labioversion


  anterior tooth positioned outside the arch toward the lips
• buccoversion


  posterior tooth positioned toward the cheek
• linguoversion


  tooth positioned inside the arch toward the tongue
• infraversion


  tooth not fully erupted or into space
• torsoversion


  tooth rotated on its axis
• transversion


  tooth in wrong order
• congenital


  present at birth
• supernumerary


  out of place
• ectopic


  out of place
• open bite


  anterior teeth do not contact with each other
• overjet


  also known as horizontal overbite, increased horizontal distance between the incisal edges of maxillary and the labial surfaces of the mandibular central incisors
• vertical overbite


  excessive amount of overlap of the maxillary and mandibular central incisors when they are in ovvlusion
• crossbite


  midsagittal alignment between central incisors not in agreement
• underjet


  maxillary incisors lingual to mandibular incisors
• end to end


  edges of maxillary and mandibular incisors meeting each other
• preventative orthodontics


  procedures taken to preserve the intergrity of a normal developing occlusion oby protecting current conditions or preventing situations that would interfere with growth
• myotherapeutic


  muscle healing treatment
• interceptive orthodontics


  procedures taken to lessen the severity of any existing malfunctions or problems from genetic or environmental factors
• corrective orthodontics

  procedures taken to reduce or eliminate malocclusion
• rotation


  turn around on an axis
• translation


  bodily tooth movement
• tipping


  change of a tooth position to a more upright direction
• intrusion


  movement of the tooth into the alveolus
• extrusion


  movement of the tooth out of the alveolus
• torque


  movement of the root without the movement of the crown
• banding


  placing a metal band around the entire selective tooth or teeth
• direct bonding


  cementing brackets of stainless steel or gold-plated metal composite
• indirect bonding


  placing and cementing brackets to tooth surfaces by means of tray delivery
• invisalign braces


  strong plastic custom trays used in mild malocclusion cases
• lingual braces


  braces that are placed on the tongue side of the teeth
• accelerated osteogenic orthodontic treatment


  surgical orthodontic "team" approach that involves placement of a regular orthodontic apparatus on the teeth and a periodontist or oral surgeon to incise the gingiva and expose the alveolar bone
