Q

what are causes of peri implant disease or failure?

A

poresthetic framework doesn’t precisely fit the abutment

patient demonstrates heavy occlusal function or parafunction

implant has been placed in poorly qualified bone or insufficient quality of bone

Q

what are non surgical treatments of TMD?

A

pharmacological relief (analgesics, muscle relaxants and pain relievers)

physical therapy (ultrasound, warm heat and spraying and stretching of muscles and jaw exercise)

mandibular splints (mouth guard)

20
Q

this identified the virus rather than antibody and thereby enables the ID of the infection earlier

A

polymerase chain reaction (PCR)

21
Q

this is the articulation between the condyle and the glenoid fossa of the temporal bone

A

TMJ

22
Q

this type of immunodefiency is common in infants… most infants die within the first year of life and are vulnerable to all forms of viral, fungal, and bacterial infections

A

Severe combined immunodeficiency

23
Q

method of evaluating a joint involving the insertion of small cannulas along with a camera and instruments into a joint

A

arthroscopy

24
Q

this was identified in 1983, transmitted through sexual contact with infected blood and infants of infected mothers.

A

HIV/AIDS

25
Q

what type of joint is TMJ?

A

hinge and sliding

26
Q

used to determine disc position (injection of contrast medium and then radiography of joint)

A

arthography

27
Q

what two antibodies test to determine HIV infection?

A

enzyme linked immunosorbent assay (ELISA)

western blot test-more specific

28
Q

categorized as disorders of the masticatory muscles, internal derangements or displacement of the disc and disorders of the joint. can lead to arthritis

A

TMD

29
Q

a transmucosal element that screws into the top of an implant fixture and can support a single crown or a framework for a fixed or detachable prosthesis

A

abutment

30
Q

what is required in order for a person to be seropositive for HIV?

A

must have 2 positive ELISAS and a positive western blot test

31
Q

a dry, crackling sound

A

crepitus

32
Q

what are the muscles of mastication?

A

masseter, temporalis and medial/lateral pterygoid muscles which causes pain via muscle spasm

33
Q

interposed in the space between the temporal bone and the mandible (divides space into superior/inferior)

A

articular disc

34
Q

what are some surgical treatments of TMS?

A

arthroscopic procedures

disc location (replacing the disc to its normal an anatomic position)

meniscectomy (complete removal of damage disc)

35
Q

what are ideal properties of dental implant material?

A

high strength, maximal inertness, ability to bend

36
Q

what are some problems that would characterize TMD?

A

problems with chewing

malocclusion

abusive habits

bruxing and clenching

problems with dentition

extensive dental or ortho treatment

history of surgical treatment of the jaws

can hear popping clicking and crepitation during movement

37
Q

this is used to detmine position and condition of disc

A

magnetic resonance imaging (MRI)

38
Q

this fills the joint spaces which lubricants the joint

A

synovial fluid

39
Q

a joint

A

articulation

40
Q

what is the maintenance of optimum health of implants?

A

plaque must be inhibited

early microbial colonization on the implant surfaces must be stopped

all existing plaque must be removed

the existing plaque much be changed from pathogenic to nonpathogenic

41
Q

what are the two types of implants?

A

endsosseous (osseointegrated)

subperiosteal

42
Q

listening to sounds within the body

A

auscultation

43
Q

what type of instruments and fluoride is used for implants

A

plastic and neutral

44
Q

this type of immunodeficiency is when the thymus is deficient or lacking and T lymphocytes do not mature

A

DiGeorges Syndrome (thymic hypoplasia)

45
Q

this is due to abnormalities in the functioning of the TMJ or associated structures

A

TMD
