Sequence for Establishing a Finger Rest


Building Blocks for Posterior Sextants

-An intraoral fulcrum acts as a “support beam”to allow precise control of instrument-Building block skills are essential for effective and safe periodontal instrumentation-While practicing fulcrums follow sequence of: Me, My Patient, My Equipment, My Nondominant Hand, My Dominant Hand, and Finger Rest


Establishing a Finger Rest


Use of Indirect Vision

-Clinicians routinely using indirect vision have less musculoskeletal strain-Practice correct clock positions and the mirror in the nondominant hand for optimum viewing of lingual surfaces

Handle Position:

-Hand in palm-UP position-Handle rests against the index finger in green shaded area

Sequence for Establishing a Maxillary Finger Rest

9


Step 1: ME

-Assure that relationship of patient to clinician is correct

10


Step 2: ME

-Assume the correct clock position

11


Step 3: My Patient

-Establish patient head position-Chin up-Chin down-Turned toward-Turned away

12


Step 4: My Equipment

-Adjust the unit light and equipment

13


Step 5: Pause and Evaluate

-Pause and self-check that you, the patient, and the equipment are all in neutral, recommended position


Step 6: My Mirror Hand

-Grasp mirror and establish a finger rest

15


Step 7: My Dominant Hand

-Grasp the instrument-Pause to evaluate the grasp

16


Step 8: My Finger Rest

-Establish a finger rest near the first tooth to be worked on

17


Step 9: Pause and Self-Check Rest

-Fingertip on secure tooth surface?-Ring finger straight, acting as support beam?-Finger placement in the grasp, still correct?

18


Clock Positions – Surfaces Toward Me

-Right Handed:Clock position 9:00

-Left Handed:Clock position 3:00


Clock Positions: Surfaces Away From Me

-Right Handed:Clock position 10–11:00

-Left Handed:Clock position 2–1:00


Preventive Strategies: Stretches

21


Benefits of Stretching

-Clinicians sit for sustained periods of time causing:– muscle tension, stiffness, and imbalances– muscle soreness and tender spots– deterioration of vertebral joints and discs

22


Benefits of Stretching (cont.)

-Warms up muscles before working-Increases range of motion, promotes flexibility and relaxation-Increases nutrient supply to vertebral discs-Perform stretches in mini-breaks between patients, every 30 to 60 minutes during workday

23


Stretching Safely

-Assume starting position for the stretch-Breathe in deeply as you begin stretch-Hold stretch for about 10 seconds-Slowly release stretch as you return to starting position-Repeat stretch if time allows


Summary

-Intraoral fulcrum improves precise instrumentation strokes, prevents sudden movements that could injure the patient, and reduces muscle load to the clinician’s hand-Strong postural muscles of trunk and shoulders stabilize the body in neutral position-Performing mini-break chairside stretches throughout the workday offers numerous benefits
