orthodontics
| Question | Answer |
|---|---|
| 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 |
