Ivoclar Optragate Cheek And Lip Retractor

Directions to use

• Step 1:

Select the appropriate size of the OptraGate. The selection of the appropriate size should be guided by the distance between the corners of the mouth when the mouth is in a relaxed position (i.e. with the lips closed or slightly open). In order to obtain sufficient retraction of the oral soft tissues, the diameter of the inner ring should ideally be approx. 2 cm wider than the mouth corner distance. Therefore the following guidelines apply:

– Size Junior: Mouth corner distance = 4.5 cm

– Size Small: Mouth corner distance = 6 cm

– Size Regular: Mouth corner distance = 7 cm

The orientation scale with the respective guide marks imprinted on the foil bag can be used as an aid in the selection of the correct size. It is important not to use a rigid orientation aid for the determination of the mouth corner distance but to follow the slightly curved course of the lips. In case of doubt, we recommend using the larger size in order to ensure a better fit. The size (R for Regular, S for Small, and J for Junior) is indicated on the packaging as well as on the left tab of the OptraGate. In order to ensure optimum function, we recommend inserting the largest possible size that fits the patient’s mouth.

• Step 2:

OptraGate may be inserted from both the 12 o’clock position with the patient lying down, or from the 8 o’clock position with the patient sitting upright (or, the 4 o’clock position if the clinician is left-handed).

• Step 3:

To ease placement, with the tabs pointing downward, the operator should grasp the thicker intraoral ring by reaching through the thinner extraoral ring. The inner ring should be held between the thumb and middle finger and pressed together slightly.
