Give examples of indirect restorations
Veneers
Inlays and Onlays
Crowns
Post and cores
Bridgework
How should the lips be examined?
Vermillion borders
Commissaries
Smile line
How should the occlusion be examined?
Incisal relationship
Excursions of the mandible - protrusion, retrusion, lateral
Canine guidance or group function?
Inter-arch space
Inter-tooth space
What are the different stages of treatment planning?
Immediate
Initial (disease control)
Re-evaluation
Reconstructive
Maintenance
Describe the immediate stage of treatment planning
Relief of acute symptoms
Consider endodontics and extractions
Consider immediate denture/bridge
Describe the initial stage of treatment planning
Extraction of hopeless teeth
OHI and dietary advice PMPR
Management of carious lesions and defective restorations with direct restorations or provisional restorations
Endodontics
Denture design, wax up for fixed pros
Describe the re-evaluation stage of treatment planning
Perio surgery
Fixed and removable pros
Describe the maintenance stage of treatment planning
Supportive periodontal care and review of restorations
Why are veneers used?
They improve aesthetics
Change teeth shape and/or contour
Correct peg-shaped laterals
Reduce or close proximal spaces and diastemas
Align labial surfaces of instanding teeth
What are the stages of veneer preparation?
Wax up
Stent
Intra-oral mock up
Preparation into mock up (can use depth cut burs)
What are contra-indications to using veneers?
Poor OH
High caries rate
Interproximal caries or unsound restorations
Gingival recession
Root exposure
High lip lines
Labial positioned, severely rotated and overlapping teeth
Extensive TSL/insufficient bonding areas
Heavy occlusal contacts
Severe discolouration
Why are inlays and onlays used?
Tooth wear cases to increase OVD
Fractured cusps
Restoration of root treated teeth
Replace failed direct restorations
Minor bridge retainers (not recommended)
What are contra-indications of placing inlays and onlays?
Active caries and periodontal disease
Time - tooth prep and lab fabrication required
Cost
Why are teeth restored with crowns?
To protect weakened tooth structure
To improve or restore aesthetics
For use as a retainer for fixed bridgework
When indicated by RPD design - rest seats clasps, guide planes
To restore tooth function - eg restore OVD
What are the contra-indications of using crowns?
Active caries and periodontal disease
More conservation options available
Lack of tooth tissue for preparation
Unable to provide post and core
Unfavourable occlusion
