2 Crowns Bridges Inlays/Onlays Veneers Fixed Prosthodontics

3 Indications for Fixed Prosthetics Prevents drifting of adjacent teeth Supports remaining teeth Prevents extrusion of teeth in opposite arch Provides stability for mastication Provides esthetic appearance Patient is motivated

4 Contraindications for Fixed Prosthetics Supportive tissue diseased or missing No suitable abutments Patient in poor health No motivation Poor oral hygiene Expense

5 Types of Fixed Prosthetics Direct restorations Amalgams Composites Glass Ionomers IV Composite Veneers Same day appointments Indirect restorations Crowns, FGC, PFM, etc. Bridges Porcelain Veneers Inlays Onlays Requires at least two visits

6 Crowns Full Cast restoration 3/4 cast restoration Porcelain fused to metal Porcelain Cerec Noble and Non-noble metals

7 Bridges Replaces missing teeth Provides stability Maryland Cantilever Abutments Pontics Units

8 Inlays/Onlays Porcelain Gold Inlays replace fossas Onlays overlay the occlusal surface

9 Veneers Direct Indirect Opaquer

10 Retention Techniques Core Buildups little tooth structure left supports cast crown provides larger area of retention can be made of oamalgam ocomposite omiracle mix

11

12 Retention Techniques Retention Pin adds support and strength placed before core material supplied in kits, pins and drills often cemented into place with zinc phosphate cement used on vital and non-vital teeth made of titanium

13 Retention Techniques Post Retained Core post place in previously RCT canal placed before core material posts are cemented in place types of posts titanium gold plated metal stainless steel pre-cast

14 Retention Techniques Implant retained occur after osseointegration single crowns bridges screw retained cement retained made of titanium

15 Gingival Retraction Ensures clear margins Subgingival/supra-gingival widens sulcus stems hemorrhaging

16 Types of Retraction Mechanical Retraction Chemical Retraction Surgical Retraction

17 Mechanical Retraction Retraction cord variety of sizes, configuration placed around tooth cotton pliers hemostat placed by Gregg 4/5 hollenback cord placement inst. 1 to 3 mm into sulcus Placed for 10-15 min.

18 Chemical Retraction Placed prior to cord Impregnated in cord Stems hemorrhaging ischemia astringent vasoconstrictor Epinephrine tachycardia

19 Surgical Retraction Electrosurgery unit removes tissue cauterizes tissue Surgical knife Indications hyperplasia Contraindications pacemakers slow healers

20 Provisional Coverage Protective covering over tooth Maintains and restores function Reduces sensitivity Prevents shifting of adjacent teeth Prevents shifting of opposing teeth Esthetics

21 Types of Provisional Aluminum Crowns Preformed Polycarbonate Crowns Custom Acrylic Crowns/Bridges Laboratory fabricated provisional

22 Criteria for Provisional Contacts must be closed Prepared margins must be covered Interproximals must be clear, no impingement on tissue Occlusal edge must be aligned with the adjacent teeth Occlusal surface should have anatomy

23 Oral Hygiene Instructions Toothbrushing instructions non-abrasive tooth paste Flossing instructions floss threading devices superfloss

24 Temporary Crown Adjustments SSC/Aluminum Crown and Bridge scissors and Contouring pliers
