QuestionAnswer
exodontia extraction of a tooth
horizontal impaction the tooth is horizontally tilted
vertical impaction tooth is in the upright position but in close proximity to, or under the crown of a nearby tooth
distoangular impaction crown of the tooth is slanted toward the distal surface and covered by tissue and/or bone
masioangular impaction crown of the tooth is mesially tilted and covered by tissue and/or bone
transverse impaction tooth is situated sideways to the adjacent teeth and occlusal plane, and is covered by tissue and/or bone
alveolectomy a procedure when multiple teeth are extracted, the alceeolar bone crests have to be removed and smoothed to prepare the ridges for denture or appliance wear
template (pattern)is used as a guide
alveolitis infection or inflammation of the alveolar process
dry socket the loss of the natural clotting
gingivectomy surgical excision of unattached gingival tissue
gingivoplasty surgical recountour of gingival tissues
periodontal flap surgery surgical excision and removal of pocket or tissue extension
frenectomy surgical removal or resectioning of a frenum
diastema a space between two teeth
ankyloglossia shortness of tongue frenum "tongue tied"
incision and drainage (I & D) procedure performed for a periodontal abscess. an incision is made into the affected area and an opening is obtained to remove and drain infected matter
malady (disease or disorder)
biopsy small tissue incision
incision biopsy removing a wedge-shaped section of affected tissue along with some normal adjacent tissue
excision biopsy removing the entire lesion of affected tissue with some underlying normal tissue
exfoliative biopsy scraping with glass slide or tongue depressor to collect tissue cells for micropscopic study
malignant harmful or growing worse
benign tumors that are not harmful
leukoplakia formation of white pathes on musous membrane of oral cavity that cannot be scraped off and have the potential for malignancy
fibroma benign, fibrous, encapsulated tumor of connective tissue
papilloma benign epithelial tumor of skin or mucous membrane
hemangioma benign tumor of dilated blood vessels
granuloma grandular tumor usually occurring with other diseases
melanoma malignant, pigmented mole or tumor
basal or squamous cell carcinoma malignant growth of epithelial cells
osteoplasty forming bone
alveolectomy usually performed to remove alveolar bone crests remaining after tooth extraction in perparation for a smooth bone ridge for denture wear
apicoectomy usually requires opening of the periodontium, including some alveolar bone, and exposure with remocal of the root apex
exostosis bony outgrowth, removing overgrowths and smoothing in preparation for dentures
torus (rounded elevation)an excessive bone growth
mandibularis torus in the mandible
palatinus torus in the palate
cysts abnormal, closed walled sac present in or around tissue
dentigerous cystic sac containing teeth
radicular cyst located alongside or at the apex of a tooth root
ranula cystic tumor found on underside of the tongue or in the sublingual or submaxillary ducts
closed fracture reduction repair with interoral fixation, tooth wiring, or ligation methods in which the teeth are "wired together" in proper alignment awaiting bone healing
open fracture reduction a more complicated procedure incolcing osteotomy and rigid fixation, perhaps bone plate, mesh, pins, grafts and other fixation divices.
genioplasty plastic surgery of the chin or cheek
macrogenia large or excessive chin
microgenia undersized chin
lateral excessive/deficient excessive bone in one direction and deficient bone in another
asymmetrical lack of balance of size and shape on opposite sides
pseudomacrogenia excess of soft tissue presenting a chin with the look of abnormal size
ptosis drooping or sagging of an organ "witches chin"
osteotomy bone incision
orthognathic surgery surgical manipulation of the facial skeleton to restore facial esthetics and proper function to a congenital, developmental, or trauma-affected patient
ridge augmentation use of bone grafts to build or correct an underdeveloped or missing ridge
arthrotomy cutting into a join
retrusive position with mandible backward
crepitus joint pain
protrusive position with mandible forward
lateral position to the side: mesiolateral is toward center of face, distolateral is toward outside of face
computerized mandibular scan (CMS) 3-D tracking device to record functional movement of the jaw during opening, closing, chewing, and swallowing
electyromyohraph (EMG) surface electrodes instrument to determine muscle activity during function: healthy muscles have low levels of electrical activity, and disarranged muscles register high activity
electrosonograph (ESG) recording of sounds during opening and closing of the jaw
CT (CAT scan) uses x-ray images taken at different angles and computerized into a cross section of anatomical features.
hemiarthroplasty surgical repair of a joint with a partial joint implant reconstruction
alloplastic reconstruction rebuilding of the joint using manmade materials
autogenous reconstruction rebuilding of the joint using organic material, such as toe and rib bone grafts
total joint reconstruction surgical intervention and use of artificial prostheses for the condyle, disc, and fossa of the temporal bone
revision surgery surgical correction of an area that has been operated upon previously, occurring when further degeneration happens, when previous implants have failed, or when going from a partial joint implant to a total implant
cleft lip tissue fissure or imcomplete juncture of maxillary lip tissues
cleft palate congenital fissure in roof of mouth with an opening into the nasal cavity; may be unilateral (one-sided) or bilateral (two-sided); also may be complete or incomplete
cleft tongue bifid or split tongue; usually split at the tip
endosteal implants placement within the bone
osseointegrated implants placement within the bone
subperiosteal beneath the periosteum and placed onto the bone
transosteal (through the mandibular bone) anchor implants that are placed all the way through the mandible
endodontic (within the tooth) titanium post placed in the apex of an endodontically treated tooth to improve the crown-root length ratio
titanum high strength; oxidizes redily on contact with tissue fluid and has a minimum amount of corrosion
ceramic is biocompatible but is not used in stressful areas
polymers and composites in the research stage; may be used as abutments in partially edentulous mouth
stainless steel and cobalt-chromium alloys older but less used materials
cobalt-chromium-molybdenum implant material used in prosthesis construction for TMJ replacement
