Digital Dentistry

• Intraoral scanners

• Computer-aided design and manucaturing (CAD/CAM)

  • used for crowns, brdiges, inlays, onlays, veneers

• 3D Printing

  • custom dental applicances, guides, models, aligners

• Digital Smile Design (DSD)

  • visulization of treatment outcomes

  • imporved patient communication and satifaction as patients can see the future design

• Cone beam computed tomography (CBCT)

  • use in implant planning, ortho, endo

• Top 3 most feared procedures

  • 1. tooth extraction

  • 2. root canal treatment

  • 3. dental impression

• Alginate impression

  • range of 75-150 microns

• PVS impression

  • 20 to 50 microns

• Intraoral scanner

  • 10 to 50 microns

  • Disadvantages

    • difficult to capture in the prescence of blood and saliva

    • there is a learning curve

Rubber Dam Placement

• Protects the patient

• protects the dentist

• saves 40% of time

• produces clean, dry field, prevents salivary contamination

• Other ways to control the operating field

  • Drugs

    • antisialogogues: not routinely used for operative procedures

    • epinepherine

    • Liquid hemostatic agents

• Anterior isolation

  • first premolar to first premolar

  • use two clamps, one on each premolar

• Posterior quadrant isolation

  • second molar to one tooth past the midline (Central incisor); clamp on 2nd molar

• Posterior 3 tooth isolation    

  • clamp the tooth that is distal to the tooth to be restored, and ligate tooth anterior to the one being resotred

• Rubber dam Clamps

  • winged and unwinged

  • some have prongs which are helpful in clamping partially erupted or broken down teeth
