Q

Dislodgment

A

Overextension or underextension

28
Q

Dislodgment overextension Tx

A

Use PIP to identify specific area for reduction

29
Q

Dislodgment underextension Tx

A

Add green stick compound or PVS to border and or posterior palatal seal; if this corrects the problem reline the denture

30
Q

Inadequate posterior palatal seal

A

Correct posterior palatal seal area with acrylic/reline

31
Q

Teeth place too far buccally or occlusal plane too high

A

Reposition teeth

32
Q

Occlusal errors

A

Remount/equilibrium occlusion

33
Q

Atypical tongue postion

A

Educate pt to keep tip of tongue forward

34
Q

Denture Reline

A

Resurfacing the intaglio of an existing denture with new denture base material thus providing an accurate adaptation tot he new foundation areas

35
Q

Whistling

A

Are escape in rugae area

Add wax in area to correct, modify denture accordingly

36
Q

Speech difficulties

A

Lisping or slushy speech anterior teeth’s et too far forward or insufficient IOD

37
Q

Noisy Denture Teeth

A

Inadequate IOD/Excessive VDO

Loose Dentures

Patient with poor NMC.lack of motor skills

38
Q

Gagging

A

Thick posterior border of maxillary denture and lingual flanges

Over extended posterior denture border

Loose dentures

Poor occlusion

Psychogenic factors

Inadequate Vertical dimension

39
Q

Soreness of the lining mucosa located at the periphery of the denture:

A

Cause overextions of peripheries

40
Q

Soreness located on the masticatory mucosa

A

Traumatic occlusion

41
Q

Soreness located not he specialized mucosa

A

Tongue biting

42
Q

Overextension of denture borders

A

Reduce round and polish

43
Q

Sharp peripheral borders

A

Round and polish

44
Q

Impingement on frenulum

A

Relieve and polish

45
Q

Cheek biting solution

A

Increase horizontal overlap by reducing buccal surface of fending mandibular tooth-provides an escape for buccal mucosa

46
Q

Cheek lip and tongue biting

A

1-2 mm overlap

47
Q

Inadequate horizontal overlap

A

Round lower buccal cusps or reset teeth

48
Q

Insufficient vertical dimension

A

Remake denture

49
Q

Teeth placed too far lingually

A

Move teeth buccally/remake denture

50
Q

Insufficient room posteriorly between tuberosity and retromolar pad

A

Reduce acrylic thickness; use metal base if insufficient restorative space; consider surgery

51
Q

Soreness on residual ridge or palate

A

Excessive Verticl dimension

Solution reduce posterior teeth via selecting bring replace teeth in or arch at correct VDO or remake dentures

52
Q

Inadequate interocclusal clearance =

A

Excessive VDO

53
Q

Excessive VDO results in

A

Soreness and discomfort under the denture

Increased ridge resorption due to trauma

May induce TMD

Generalized soreness and discomfort

54
Q

Brushing solution

A

Educate patient

Remove dentures to allow oral soft tissues to reset

55
Q

Thin mucosa over bony exostosis and tori

A

Relive denture and refer to oral surgery

56
Q

discomfort upon insertion or removal of denture past undercuts

A

Use PIP to locate and relieve area of denture that interferes/binds

57
Q

Reflective occlusal contacts that cause soreness under lingual and labial flange of mandibular denture

A

Rebound dentures on articualtor and correct occlusion

58
Q

Soreness on RR or palate generalized

A

Occlusal discrepancy

Remount dentures on articulator and equilibrate and refine occlusion

59
Q

Clinical remounts Save _____ and reduce _____

A

Save chair time and reduce poster insertion visits

60
Q

Clinical remounts

A

Corrects occlusal discrepancies

Allows extra oral occlusal adjustment

Minimizes related removal and replace the of the dentures

Allows identification of interferences not seen intraorally and undesired denture base contacts

61
Q

Failure to correct occlusion before the patient wears the dentures

A

can cause destruction for he residual alveolar ridge

62
Q

Chronic displacement of the complete denture bases leads to

A

Soreness and inflammation which in turn cause accelerated bone loss of the residual ridges

63
Q

Clinical remount can help correct

A

Both processing changes and errors

64
Q

Denture occlusion must observe

A

Uniform simultaneous bilateral centric contacts

65
Q

_____lessen displacement and tipping of denture bases

A

Smooth gliding non interfering contacts to any eccentric postion lessen displacement and tipping of denture bases

66
Q

Goals of clinical round

A

To eliminate defective contacts

Provide evenly distributed simultaneously balanced occlusal contacts at the correct VDO

67
Q

Advantages of a clinical remount

A

Stable foundation without shifting denture bases

better visualization of occlusal contacts

Absence of salvia provide accurate occlusal contacts

Reduced clincal time and adjustment appointments
