Tips <strong>on</strong> surgical procedure<br />
rapid surgery with gentle tissue handling has a positive effect <strong>on</strong> <strong>the</strong> postoperative course, for instance, less pain,<br />
minimal or no swelling, less susceptibility to infecti<strong>on</strong> and uncomplicated wound healing.<br />
The following factors should be taken into account when shaping <strong>the</strong><br />
implant bed<br />
p copious (external) cooling with chilled (5 °c) 0.9% naci soluti<strong>on</strong>.<br />
p use sharp instruments (see “overview of wear“, art. no. 152.007)<br />
p use cutting instruments in ascending order (diameter).<br />
p maximum drill speeds:<br />
Ø 2.2 mm: max. 800 rpm, Ø 2.8 mm: max. 600 rpm<br />
Ø 3.5 mm: max. 500 rpm, Ø 4.2 mm: max. 400 rpm<br />
p apply <strong>on</strong>ly light pressure.<br />
p intermittent drilling acti<strong>on</strong>.<br />
Warning<br />
<strong>the</strong> use of a spray or water jet flowing directly from <strong>the</strong> drill unit for cooling purposes<br />
when working with b<strong>on</strong>e is c<strong>on</strong>traindicated because <strong>the</strong> tubes and hoses that supply<br />
<strong>the</strong> drill unit may be c<strong>on</strong>taminated with pathogenic micro-organisms.<br />
Using <strong>the</strong> cutting instruments<br />
p Multi-use round burr: <strong>the</strong> implant positi<strong>on</strong> is marked before <strong>the</strong> start of <strong>the</strong><br />
implant bed shaping with <strong>the</strong> smallest round burr (see implant Distance indicator,<br />
page 20). <strong>the</strong> roughened spot is enlarged and/or corrected with <strong>the</strong> medium<br />
round burr. <strong>the</strong> biggest round burr is used to smooth <strong>the</strong> alveolar ridge.<br />
p Multi-use Pilot and Twist drills: <strong>the</strong> implant bed is prepared with <strong>the</strong>se drills in<br />
ascending order. <strong>the</strong> marking is c<strong>on</strong>tinuous between 10 mm and 12 mm, where<br />
<strong>the</strong> lower edge of <strong>the</strong> marking corresp<strong>on</strong>ds to 10 mm and <strong>the</strong> upper edge to<br />
12 mm. this makes it easy to keep to <strong>the</strong> drilling depth. Due to <strong>the</strong> functi<strong>on</strong> and<br />
design of <strong>the</strong> drills, <strong>the</strong> drill tip is 0.4 mm l<strong>on</strong>ger than <strong>the</strong> depth of inserti<strong>on</strong> of <strong>the</strong><br />
implant.<br />
p Single-patient pilot and twist drills: like <strong>the</strong> multi-use drills, single-use drills are<br />
indicated for <strong>the</strong> preparati<strong>on</strong> of <strong>the</strong> implant bed for straumann Dental implants.<br />
<strong>the</strong>y are supplied sterile and must be used <strong>on</strong>ly during <strong>on</strong>e operati<strong>on</strong> for <strong>on</strong>e<br />
patient. single-use drills can minimise <strong>the</strong> risk of infecti<strong>on</strong> for <strong>the</strong> patient and are<br />
color coded for easy identificati<strong>on</strong> of <strong>the</strong> diameter.<br />
Due to <strong>the</strong> functi<strong>on</strong> and design of <strong>the</strong> drills, <strong>the</strong> drill tip is 0.4 mm l<strong>on</strong>ger than <strong>the</strong><br />
depth of inserti<strong>on</strong> of <strong>the</strong> implant.<br />
new generati<strong>on</strong> single-patient drills are drill stop compatible. <strong>the</strong>y can be ordered<br />
by using separate article numbers.<br />
