25
Overextension in posterior of maxillary denture
Locate using PIP relieve and polish
26
Excessive vertical dimension can make
Swallowing difficult Need to correct VDO by resetting teeth/remake
27
Dislodgment
Overextension or underextension
28
Dislodgment overextension Tx
Use PIP to identify specific area for reduction
29
Dislodgment underextension Tx
Add green stick compound or PVS to border and or posterior palatal seal; if this corrects the problem reline the denture
30
Inadequate posterior palatal seal
Correct posterior palatal seal area with acrylic/reline
31
Teeth place too far buccally or occlusal plane too high
Reposition teeth
32
Occlusal errors
Remount/equilibrium occlusion
33
Atypical tongue postion
Educate pt to keep tip of tongue forward
34
Denture Reline
Resurfacing the intaglio of an existing denture with new denture base material thus providing an accurate adaptation tot he new foundation areas
35
Whistling
Are escape in rugae area Add wax in area to correct, modify denture accordingly
36
Speech difficulties
Lisping or slushy speech anterior teeth’s et too far forward or insufficient IOD
37
Noisy Denture Teeth
Inadequate IOD/Excessive VDO Loose Dentures Patient with poor NMC.lack of motor skills
38
Gagging
Thick posterior border of maxillary denture and lingual flanges Over extended posterior denture border Loose dentures Poor occlusion Psychogenic factors Inadequate Vertical dimension
39
Soreness of the lining mucosa located at the periphery of the denture:
Cause overextions of peripheries
40
Soreness located on the masticatory mucosa
Traumatic occlusion
41
Soreness located not he specialized mucosa
Tongue biting
42
Overextension of denture borders
Reduce round and polish
43
Sharp peripheral borders
Round and polish
44
Impingement on frenulum
Relieve and polish
45
Cheek biting solution
Increase horizontal overlap by reducing buccal surface of fending mandibular tooth-provides an escape for buccal mucosa
46
Cheek lip and tongue biting
1-2 mm overlap
47
Inadequate horizontal overlap
Round lower buccal cusps or reset teeth
48
Insufficient vertical dimension
Remake denture
49
Teeth placed too far lingually
Move teeth buccally/remake denture
50
Insufficient room posteriorly between tuberosity and retromolar pad
Reduce acrylic thickness; use metal base if insufficient restorative space; consider surgery
51
Soreness on residual ridge or palate
Excessive Verticl dimension Solution reduce posterior teeth via selecting bring replace teeth in or arch at correct VDO or remake dentures
52
Inadequate interocclusal clearance =
Excessive VDO
53
Excessive VDO results in
Soreness and discomfort under the denture Increased ridge resorption due to trauma May induce TMD Generalized soreness and discomfort
54
Brushing solution
Educate patient Remove dentures to allow oral soft tissues to reset
55
Thin mucosa over bony exostosis and tori
Relive denture and refer to oral surgery
56
discomfort upon insertion or removal of denture past undercuts
Use PIP to locate and relieve area of denture that interferes/binds
57
Reflective occlusal contacts that cause soreness under lingual and labial flange of mandibular denture
Rebound dentures on articualtor and correct occlusion
58
Soreness on RR or palate generalized
Occlusal discrepancy Remount dentures on articulator and equilibrate and refine occlusion
59
Clinical remounts Save _____ and reduce _____
Save chair time and reduce poster insertion visits
60
Clinical remounts
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
Failure to correct occlusion before the patient wears the dentures
can cause destruction for he residual alveolar ridge
62
Chronic displacement of the complete denture bases leads to
Soreness and inflammation which in turn cause accelerated bone loss of the residual ridges
63
Clinical remount can help correct
Both processing changes and errors
64
Denture occlusion must observe
Uniform simultaneous bilateral centric contacts
65
_____lessen displacement and tipping of denture bases
Smooth gliding non interfering contacts to any eccentric postion lessen displacement and tipping of denture bases
66
Goals of clinical round
To eliminate defective contacts Provide evenly distributed simultaneously balanced occlusal contacts at the correct VDO
67
Advantages of a clinical remount
Stable foundation without shifting denture bases better visualization of occlusal contacts Absence of salvia provide accurate occlusal contacts Reduced clincal time and adjustment appointments
