Module 7 - Finger rest in Maxillary Posterior sextants + Stretches

Building block for posterior sextants

Sequence for establishing a finger rest

Me

• Assume the block position for treatment area

Patient

• Establish patient chair and head position

My equipment

• Adjust the unit light. Pause and self check the clinician, patient, and equipment position

Non—dominant hand

• Grasp mirror and establish finger rest

Dominant hand

• Grasp instrument and pause to evaluate finger placement in grasp

Finger rest

• Establish finger rest near first tooth to be treated

Pause to evaluate finger rest

• Is tip of ring finger on a secure tooth surface?

• is ring finger straight, acting as a support beam?

• Is my finger placement in the grasp still correct?

Upcoming flashcards practice for finger rest (Maxillary posterior, toward)

Refer to pohotos

Maxillary left posterior sextants, facial aspect

• 3 o’ clock position

• Chin up

Mirror use (Retraction)

• Retract the buccal mucosa w/ the mirror

• Use mirror for indirect vision to view distal surfaces

  • Use extraoral finger rest w/ dental mirror

1. Second molar, facial aspect

• Finger rest on the occlusal surface

2. First premolar, facial aspect

• Finger rest on incisal surface of one of maxillary anterior teeth

Maxillary right posterior sextants, Lingual aspect

• 3 o’ clock position

• Chin up

Mirror use

• Use mirror to view the distal surfaces of the teeth

1. Second molar, lingual aspect

• Finger rest on the occlusalfacial line angle

2. First premolar, lingual aspect

• Finger rest on occlusofacial line angle or incisal edge

Upcoming flashcards practice for finger rest (Maxillary posterior, away)

Maxillary right posterior sextants, facial aspect

• 1—2 o’ clock position

• Chin up

Mirror use (Retraction)

• Retract the buccal mucosa w/ the mirror

• Tip: Dominant hand is positioned corectly if you can see the underside of middle and ring fingers

1. Second molar, facial aspect

• Finger rest on the occlusal surface

2. First premolar, facial aspect

• Finger rest on incisal surface of one of maxillary anterior teeth

Maxillary left posterior sextants, Lingual aspect

Preventative strategies: Stretches

• Muscle health, balance of forces, blood flow

• Hold stretches 10—30 seconds

• Strong trunk and shoulders stabilize body in neutral position

• Most hygienist sit for long period of time = muscle tension & stiffness

• Unbalanced muscle position = muscle imbalances (tightness in 1 group and weakness in another = MSD)

1. Take work breaks, chair stretching throughout the day between patients

2. Rec to chair stretch every 30—60 mins throughout the day

Benefits of stretching

• Warms up muscle before work

• Prevent strains and spams

• Decrease soreness and tender spots

• Increase production of joint synovial fluid — reduce joint friction

• Increase range of motion, promote flexibility

• Increase nutrient supply to vertebral disc of spine

• Reduce stress and promote relaxation

How to stretch safely

• Assume starting position

• Breath in as you begin stretch

• Hold stretch for 10 secs

• Slowly release to starting position. Repeat stretch.

• Never stretch in painful range. If pain, stop immediately

Types of stretches

• aching back

• Lift back

• Important thumb

• Open and close

• ear to armpit

• Chin to chest

• up and over

• crack a walnut

• spinal twist / variation

• roll down

• ear to shoulder rainbow

• wrist relaxer
