Surgical Technology for the Surgical Technologist: A Positive Care Approach: Chapter 18 Oral and Maxillofacial Surgery Flashcards

Alveolar Mandibular Process

Alveolar Maxillary Process

Portion of the jaw that surrounds and supports the tooth

Occurs along with the development of the cranium around the sixth week of embryologic life

Connects each ramus to the body

Harvested from the patient

Distal to the cuspids, 2 on each side, upper and lower, used to break up food into smaller portions

Lies horizontally and contains the alveolar process for the lower teeth, Mental foramen is below the first molar tooth, the mental protuberance is the chin

Cheek side of teeth

Flat plate (plain x-ray film); nose and forehead placed against the cassette; good view of hard palate, orbital floor, nasal septum, and zygoma

Bone like substance that covers the tooth from the termination of the enamel at the neck to the thickest region at the apex of the root

Lateral walls of the oral cavity

Enamel of cap of crown only

Extend into the dentin of the tooth; do not expose the pulp

Extensive damage to coronal portion; expose pulp

At or below the cementoenamel junction of the tooth

Occur within the capsular head of the mandible

Paget's disease or acromegaly can cause development disturbances in the jaw

A birth defect in which one or more of the joints between the bones of the baby's skull close prematurely before the brain is fully developed, head may be misshapen

Portion above the gumline

Best view for bony structures in a series of views/planes

Lateral to the incisors, 2 upper and 2 lower, used to grasp and shred foods

Cavities, decay of tooth enamel

Forms the majority of the crown, harder than bone and encases the pulp

Double vision

Split sheet is draped over patient and around face, doctor preferance

Sagging of eye

Controls the movement of the tongue

Symphisis and parasymphyseal, Horizontal ramus, Mandibular Angle, and Condyle

4 classifications

Coronal incision, follows patient's natural hairline and can be extended to tragus

Approached as craniotomy and requires a craniotomy setup

Aid in speech and breakdown of food

Anterior, made of the maxillary and palatine bones

Harvested from a dissimilar species

Harvested from another person, same species

Occur along the lateral portion of the mandible between the bicuspid teeth and molars

How are dental caries diagnosed

How is a symphysis and/or parasymphyseal fractures repaired

How long does it usually take for a bone to heal

How many Cranial Bones are there

How many facial bones are there

How many Facial Muscles are there

How many orbital bones are there

How many Skull Bones are there in total

Four front teeth used to tear food

Controls the shape of the tongue

Side of tooth that lies closest to the lips

Eye orbit

Asymmetry with respect to each side of jaw

AKA-Transverse Maxillary Fracture, usually occurs from a motor vechicle accident, bilateral horizontal fractures of the maxilla, below the nose

Referred to as panfacial frangures, triangular, exteds from dorsum of nose, across medial walls of orbit across maxilla below the zygomatic bone

Referred to as panfacial fractures, facial bones, including the zygomas are detached from the anterior cranial base, fracture line exteds from the dorsum of the nose and cribriform plate along the medial tip of the lateral wall of the orbit

Tongue side of teeth

Attaches the tongue to the floor of the buccal cavity

Abnormally large jaw

Misalignment of the aveolar process of the jaw bones in an overbite or underbite

Body, Ramus, and Angle

Occurs from the second molar to the ascending ramus

Abnormally small jaw, Paget's disease causes an overgrowth of the bone in the cranium, maxilla, and mandible

2 maxilla, 2 palatine, and sphenoid bone

Hand held retractor, double angle, retracts tongue or cheek

Flat-topped teeth, 3 on each side, upper and lower, used to break up food

Prevent injury to surgical staff, maintains mouth in open position, facilitates visualization, prop is placed on unaffected side

Best view for soft tissue and congenital defects in a series of views/planes

Junction of the crown and root

Involves resection of the soft tissue and excision of the bone surrounding the tooth prior to removal of the tooth

Contains fat for protection from shock and also contains the optic nerve-2nd cranial nerve

Cerebral Spinal Fluid leaking from ear

Hard and Soft

One x-ray with excellent view of all the alveolar processes and mandible

Protects the patient's lips

Entire face is prepped, from hairline to sternal notch

20 teeth, deciduous, usually start coming out at 6 months of age

Contains the blood vessels, nerves, and connective tissue

Immobilization of jaw following mandibular and/or maxillary fracture

Project upward at an angle from the posterior part of each mandibular body, the condylar process is the posterior projection of the ramus, Coronoid process is the anterior projection of the ramus

Underdevelopment of the mandible

Cerebral Spinal Fluid leaking from nose

Portion below the gumline

32 teeth, permanent, beginning at about the age of 6

Drill, Measure, Tap, Screw

Posterior, Consists of muscles

Occurs below the capsule

Occur along the mandible between the bicuspid teeth, hematomas can form sublingually due to damage along the floor of the mouth

Involves the removal of a tooth or teeth that cannot be salvaged by restoration or those that inteerfere with occlusion

Synovial joint, formed at the bicondylar junction of the mandible and the temporal bones, the mandible articulates with the glenoid fossa of each temporal bone

Crown, Root, and Neck

Consists of the condylar process, portions of the temporal bone, mandibular fossa, and articular tubercle

Thick muscular organ covered with mucous membrane lining that consists of chemoreceptors for taste

Extrinsic and Intrisic

Innervates the 4 muscles of the lower jaw

Lymphoid Tissue

Inferior posterior nasal septum

Flat plate (plain x-ray film) with neck hyperextended; nose and chin against the cassette; view frontal/maxillary sinus and infraorbital rim

Little sponges used for ophthalmic procedures, designed for use in delicate surgical areas
