1. COURSE DESCRIPTION
   This course includes practical procedures for performing those expanded functions as delegated to dental auxiliaries in the State of Vermont. It includes, but is not limited to, practical procedures in placement, condensing, carving, and finishing temporary, amalgam, and composite restorations, placement of rubber dams, matrices, and the fabrication of crowns, bridges and impressions. This course may be taken by Certified Dental Assistants (CDAs) and Registered Dental Hygienists (RDHs) after they have been accepted into the EFDA program. The course is taken in conjunction with EFDA 210 to enhance didactic instruction.
2. COURSE PHILOSOPHY
   This laboratory course enables the student to become laboratory competent in expanded functions skills prior to performing them in satellite offices.
3. COURSE OBJECTIVES
   Upon completion of the course, the EFDA student will:
   1. Demonstrate the procedure for performing intra- and extra-oral inspections of the oral cavity.
   2. Differentiate classes of cavity design.
   3. Master the techniques for fabricating study models from alginate impressions.
   4. Monitor vital signs on classmates.
   5. Demonstrate proper body positioning and instrument use in restorative dentistry (using a typodont).
   6. Manipulate cements, bases and liners and insert in designated areas into supplied cavity preparations.
   7. Assemble and place matrices and wedges.
   8. Triturate and condense amalgam into various classes of cavity preparations using sufficient condensation pressure.
   9. Fill cavity preparations completely and provide sufficient bulk to facilitate carving of functional anatomy.
   10. Carve a smooth amalgam restoration which restores the functional anatomy of a tooth.
   11. Manipulate the liners, etchants, primers and bonding agents used in composite restorations.
   12. Select a shade and insert sufficient amount of composite into cavity preparation.
   13. Demonstrate finishing procedures for composite restorations.
   14. Operate laboratory lathe and handpieces according to instructions.
   15. Demonstrate the different methods for fabricating temporary crowns and bridges.
   16. Demonstrate routine maintenance of a dental operatory in accordance with the criteria set forth on the competency requirements for EFDA 212.
   17. Demonstrate placement and removal of the rubber dam as the ideal isolation technique in restorative dentistry.

5. SPECIFIC COURSE OBJECTIVES
   Unit 1: Preliminary Procedures
   The student will:
   • Demonstrate the entire procedure for performing an intra- and extra-oral inspection.
   • Illustrate the six classes of cavity design.
   • Demonstrate the entire procedure for monitoring patient's vital signs.
   • Display proper operator and patient positioning throughout procedures.
   • Demonstrate proper technique and concern for patient while taking alginate impressions on partner.
   • Fabricate study models from alginate impressions.
   • Prepare the rubber dam as a form of isolation in restorative procedures
   Unit 2: Restorative Dentistry - Amalgam
   The student will:
   • Prepare and manipulate cements, bases and liners according to manufacturer's instructions.
   • Insert each material according to requirement of cavity preparation design function desired and restorative material using effective instrument grasp.
   • Manipulate amalgam according to manufacturer's instructions, using mercury hygiene.
   • Assemble matrix retainer according to quadrant/tooth being restored.
   • Place matrix band assembly onto tooth being restored according to stated criteria.
   • Demonstrate proper wedge placement.
   • Adapt amalgam to all aspects of cavity preparation using condensation pressure suggested by amalgam manufacturer.
   • Fill cavity prep completely with amalgam, leaving no voids. Provide sufficient bulk of amalgam to facilitate carving of functional anatomy.
   • Use effective instrument grasp and stable fulcrum, following a systematic carving procedure to remove excess amalgam while creating functional anatomy.
   • Inspect carved restoration for sealed cavosurface margins, functional anatomy and overall smoothness of amalgam.
   • Check occlusion of restoration and adjust amalgam height/contour.
   • Adjust margin anatomy, finish and/or contour until restoration is adequately finished and polished.
   Unit 3: Restorative Dentistry - Composites
   The student will:
   • Select the proper type of composite resin according to location and/or size of cavity preparation.
   • Prepare and manipulate composite and adjunctive materials according to manufacturer's instructions.
   • Demonstrate isolation procedures necessary for placement of a composite resin.
   • Select proper base/liner materials and insert into desired areas of cavity preparation.
   • Demonstrate placement of posteriors matrices, anteriors mylars strip and wedging.
   • Select proper shade of composite resin and begin inserting into preparation.
   • Using proper fulcrum, finish restoration by removing all excess restorative material with a handpiece, contouring restoration to reproduce anatomy and check and adjust occlusion.
   • Use proper sequence to polish composite restoration.
   Unit 4: Temporary Restorations
   The student will:
   • Prepare and manipulate materials used for temporary restorations according to manufacturer's instructions.
   • Insert mixed material into cavity preparation adapting to cavity walls with condensation pressure.
   • Remove excess restorative material to restore tooth to its original form and function.
   • Check occlusion of temporary restoration and adjust, if necessary.
   Unit 5: Prosthetics
   The student will:
   • Illustrate the parts of a crown preparation.
   • Demonstrate isolation and lubrication procedures necessary for fabricating temporary crown and/or bridges.
   • Select proper size of preformed temporary crowns by measuring mesial-distal space as well as height of tooth.
   • Demonstrate procedures for adapting preformed crowns to exact dimensions of the tooth.
   • Demonstrate procedure for fabricating acrylic block temporary crowns and bridge (squash technique) and provisional options including a direct and indirect technique.
   • Demonstrate how to reline temporary crowns and bridges.
   • Demonstrate trimming/carving procedures for all surfaces of temporary crowns and bridges.
   • Polish temporaries in the laboratory using proper polishing agents.
