  5. How do I use the EXD 11/12? • Assessment strokes • Physical strength NOT required • EXD 11/12 • Small, overlapping • Vertical, oblique, horizontal • RELAXED modified pen grasp • Activation • Hand-forearm motion • Digital motion

  6. EXD 11/12 - Specifics • Side of tip 1/3 always touches tooth • Never use point • Very light, small, overlapping strokes • Visualize contour of teeth and roots

  7. Posterior Teeth • Select correct working end • VISUAL CHECK • Check terminal shank at DISTAL of premolar • Terminal shank will be parallel to long axis of tooth • Tip directed toward D of tooth YES NO

  8. Adaptation & Activation for Posterior Teeth

  9. Adaptation & Activation • Place terminal shank @ DB line angle • tip pointed toward DISTAL • Keep terminal shank parallel to long-axis of tooth • Insert tip to base of sulcus • Small overlapping strokes • ROLL handle, advance interproximally • half way across D

  10. Adaptation & Activation • Back out, roll handle so tip pointed toward mesial • Keep fulcrum on tooth • Explore entire Buccal surface • Keep tip sub-gingival

  11. Adaptation & Activation • ROLL handle to keep side of tip 1/3 adapted around MB line angle • Advance interproximally • Under contact • Half way across M • Use opposite working-end for L surfaces

  12. Anterior Teeth • VISUAL CHECK • Terminal shank will cross over midline • Working-end curves around tooth surface working toward • Side of tip 1/3 touches tooth surface (1-2mm) • NOT point

  13. Adaptation & Activation for Anterior Teethfor R & L Handed Clinicians • Insert tip to base of sulcus at midline • Tip pointed in direction of surfaces toward • ROLL handle at line angle • Small overlapping strokes • Explore all surfaces toward, then flip ends for surfaces away • Complete all F surfaces, then L • Overlap @ midline • Use horizontal stroke R: toward / L: away R: away / L: toward

  14. Challenges for Maintaining Adaptation • Line angles • Convex and rounded surfaces • Proximal root surfaces • Operator positioning

  15. Why would I miss calculus? • Irregular calculus pattern • Instrument choice • Wrong explorer • Wrong end • Grasp • “Death-Grip” • Middle finger • Too much pressure • Incorrect position • Strokes • Not overlapping • Too big
