OVerdenture and Relines Flashcards
Do natural teeth have greater or lesser chewing force than prosthetic teeth?
Greater
What direction does the maxilla resorb?
Up and in
Maxillary CD opposed by mand anterior natural teeth
Combination syndrome
What are the 5 elements of the combination syndrome?
Max ant tissue mobile/hyperplasia
Inflammatory palatal hyperplasia
Maxillary tuberosity enlarged
Mand posterior bone resorption
Mand anterior teeth supraerupted
Combo of cure of speee and wilson
coronal and sagitaal planes
Concave in mand convex in max
centric occlusion form a segment of a sphere of 4 inches radius with the center of sphere at the glabella
Curve of monson
In a tilted molar case where a bridge is tp, what is likely need for accesss on the distal?
DIstal wedge
Biting force of natural dentition if abou ___ x force of the denture wearers
5x
DOes max or mand anterior resorb faster?
Mand 4x as fast
Adv of _____:
Denture support is increased and soft tissue trauma is decreased
Stability of denture is increased
Maintenance of perio proprioception improves chewing efficiency
Psychological benefit to pt
Overdenture
Disadv of ___;
-Cost
Bulkier denture in some areas
Denture more prone to fracture
Caries/perio sequelae
Overdenture
How often are relines needed?
4-7 years
Replacing intaglio surface of prosthesis: shell of denture sent to lab: changes internal surface
Reline
Replacing entire denture base and cameo surface
Rebase
All of the exisiting denture base is replaced with new resin without altering relationship of teeth
Rebase
In order to a reline to be acceptable to do, what 2 things must the exxisiting denture have?
Acceptable OVD
Acceptable occlusion
What 2 forces does a reline address in a denture?
Retention and stability
Do you want pt to close when relining denture?
Yes
Do you want pt to close when relining RPD?
NO
The study of the distribution and
determinants of health-related
states or events (including
disease), and the application of
this study to the control of
diseases and other health
problems.
Epidemiology
The ongoing, systematic collection, analysis, and
interpretation of health-related data essential to
planning, implementation, and evaluation of
public health practice.
Public health surveillance
