Work Instruction GUIDE-SYSTEM

Guide System 21 Gingiva punching (optional) As an alternative to conventional flap preparation of the gingiva, the Guide System gingiva punch can be inserted into the guiding sleeve and the gingiva pierced and removed at the implant position. 15 rpm should not be exceeded if rotating application is used. To prevent connective tissue encapsulation in the implant bed, any remai- ning gingiva must be removed from the drilling area and the marginal gin- giva mobilized, if necessary. General information on pilot, pre- and form drilling • To avoid abrasion of the guide sleeves with drill cutting edges, the drill should not be set in rotation until its cylindrical guide shaft is incontact with inner surface of the guide sleeve. • The pilot drill, pre-drill and form drill are used with an intermittent technique, i.e. drill the bone for two to three seconds and then with draw the drill upwards from the bone without stopping the hand motor. Repeat this procedure until the desired depth is reached. • Drilling must be carried out with adequate cooling using pre-chilled (5° C) sterile physiological saline solution. The drills are used in ascending lengths.
