orthodontics

QuestionAnswer
orthodontia (straigh tooth) is the study dealing with the prevention and correction of abnormally positioned or misaligned teeth
orthodontist the dentist that is concerned with the causes and treatment of malocclusion
centric relation the most retruded position of the madibular condyle into the glenoid fossa(biting on the back teeth)
neutroclusion class 1 condition, in which the antero-posterior occlusal positions of the teeth or the mesiodistal positions are normal but other malocclusion or positioning of the individual teeth occurs
distoclusion class 2 condition, in which the mesiobuccal cusp of the maxillary first molar is anterior to the buccal groove of the mandibular first molar, resulting in an appearance of a retruded mandble
congenital present at birth
supernumerary or 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 mandibular central incisors
vertical overbite excessive amount of overlap of maxillary and mandibular central incisors when they are in occlusion
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
preventive orthodontics action taken to preserve the integrity of a normal developing occlusion by protecting current conditions or preventing situations that would interfere with growth, such as correction of caries, poor nutrition, elimination of hapits through exercises
myotherapeutic muscle healing treatments
interceptive orthodontics procedures taken to lessen the severity of any existing malfunctions or problems from genetic or enviromental factors, such as placement or use of appliances to correct improper growth patterns
corrective orthodontics procedures taken to reduce or eliminate malocclusion; treatment plans include the application of intraoral and extraoral appliances and auxiliary forces or tooth direction
rotation (turn around on an axis) altering the position of a tooth around its long axis
translation bodily tooth movement; a change of teeth to alternate postions
tipping change of 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 movement of the crown
banding placing metal band around entire selective tooth or teeth
direct bonding cementing stainless steel or golden metal brackets on the surface of the teeth to attach needed pressures and archwire forms
viazis a triangular bracket using a low-force square or rectangular bracket
damon self-ligating system bracket, which does away with elastics and requires fewer appintments and adjustments
invisalign braces strong plastic custom trays used in mild malocclusion cases
ligual braces braces that are placed on the tongue side of the teeth
accelerated osteogenic orthodontic treatment surgical orthodontic team approach that involves incising the gingiva to expose the alveolar bone, where a surgical drill is used to place holes to weaken and demineralize the bone
adjunctive orthodontics procedures taken to facilitate other dental procedures that are necessary to correct or restore function
cephalometric radiographs (measurements of the head)used for elvaluation of dentofacial development in tracings for future growth patterns and directions
bands stainless steel circles or rings that are sized and cemented around a tooth
bracket (support) a metal or clear resin holding device sued to support and stabilize the archwire in the mouth
DB's (direct bonded) brackets that are cemented directly on the suface of the tooth
archwire horeseshoe-shaped stainless steel or nikel titanium wire that may be round, rectangular, or square and removable or fixed
buccal tubes support devices soldered on the bands into which headgear and archires are inserted
button, cleats, hooks, eyelets devices used for support and holding power devices, elastics, and wires
ligature (binder or tie off) thin, stainless steel wires used to tie on or attach archwires and any necessary attachments
elastics sized latex circles providing various pull forces, or elastomeric ties for holding
auziliary springs noble metal or stainless steel attachment to apply directional force
separators (device to set aside) brass wire, steel springs, or elastomeric materials placed between the teeth to obtain space before placing the bands
headgear device composed if facebow and traction. it is used to apply external force
facebow stainless steel external archbow device that is inserted into the fixed molar tubes on the maxillary fist molars
traction device fitted, expandable device to be hooked onto a facebow after placement on the head
cervical device circles the patient's neck and attaches to facebow to pull in a parallel position to retract teeth
high-pull device fits on top of the patient's head and hooks in a downward position, perpendicular to occlusion, to retract anterior teth and control maxillary growth
combination high-pull and cervical device traction combining both forces
chin device placed on the chin, incorporates high-pull and cervical forces and is used to control mandible growth
aligner an invisalign system of computer-imaged and computer-generated clear platic overlay trays used with milder cases of misaligned teeth
activator appliance designed to guide, change, or alter facial and jaw functions for a more favorable occlusion position
hawley appliance removable, customized, acrylic and wire appliance designed to maintain newly acquired tooth positions
stev plate maxillary bite plane covering incisal edges of maxillary incisors; may be used in conjunction with headgear or for retntion of the bite
crozat appliance removable appliance made of precious alloy with body wires, lingual arms, and a high labial archwire (maxillary); molar clasps hold the appliance in place
lingual retainer mandibular lingual bar with cuspid-to-cuspid cemented unions, to maintain lower incisors in position
lingual arch retainer when lingual retainer is extended and attached to the mandibular molar to molar areas
orthodontic tooth positioner customized mouth device constructed of soft acrylic or rubberized material surrounding the crowns of all the teeth in both jaws
palatal expanders known as RPE (rapid palatal expanders) a fixed appliance cemented to the maxillary molar teeth with a spring insert in the palate area
fixed space maintainer custom-constructed appliance attached to the remaining teeth to hold a tooth pattern or to maintian space from premature loss of tooth
oral shield device that fits into the vestibule space between the teeth and th lips; helps to train and maintain lip function by correcting habits, strengthenig lip action, or correcting mouth breathing faults
mouthgaurd though not considered a treatment appliance, protects the tooth position while the patient is involved in sport activities
dental appliances specialized mouth appliances for health disorders such as sleep apnea, thumb sucking, nail biters, and tongue thrusters
