3.1.1 Mesiodistal implant positi<strong>on</strong><br />
The mesiodistal b<strong>on</strong>e availability is an important factor for choosing <strong>the</strong> implant type and diameter as well as <strong>the</strong><br />
interimplant distances in <strong>the</strong> case of multiple implants. The point of reference <strong>on</strong> <strong>the</strong> implant for measuring mesiodistal<br />
distances is always <strong>the</strong> shoulder, being <strong>the</strong> most voluminous part of <strong>the</strong> implant. Note that all distances given in this<br />
chapter are rounded off to 0.5 mm. The following basic rules must be applied:<br />
Rule 1<br />
Distance to adjacent tooth at b<strong>on</strong>e level:<br />
A minimal distance of 1.5 mm from <strong>the</strong> implant shoulder to <strong>the</strong> adjacent tooth at b<strong>on</strong>e level (mesial and distal) is required.<br />
S/SP implants TE implants BL implants<br />

Rule 2<br />
Distance to adjacent implants at b<strong>on</strong>e level:<br />
A minimal distance of 3 mm between two adjacent implant shoulders (mesiodistal) is required.<br />
