During planning, besides all clinical considerations, it is important to consider the technical constraints for the position of the guided sleeves in relationship to the radiographic guide and/or the dental scan. Tthe position of the guided sleeves needs to be verified with the radiographic guide and/or the dental scan shown.
Each sleeve should be positioned within the radiographic guide to ensure that there is sufficient material in the surgical template to support the sleeve.
1. Correctly positioned 2. Incorrectly positioned: the sleeve is placed too distant and is not connected to the radiographic guide

It is necessary to verify the depth of the sleeve in
relationship to the radiographic guide. The sleeve should not penetrate
the surface facing the gingiva (intaglio surface) in order to secure the
correct position of the surgical template. In order to verify the depth
of the sleeve, view the position of the sleeve and fine-tune the implant
depth using the Depth icon in the dedicated toolbar.
Alternatively, when a pilot sleeve is chosen, consider adjusting the sleeve
offset.
1. Correctly positioned 2. Incorrectly positioned: the sleeve is placed too deep

Verify sleeve positions after implant planning. The following situations must be resolved:
Lateral collisions are collisions with neighboring teeth or potentially with soft tissue (surface scan of the intraoral situation). If a collision occurs, verify whether the position of the implant can be changed so that the collision warning is not triggered. If this is not possible, try to narrow the sleeve diameter or choose the pilot drilling only option. Advanced users can also consider skipping parts of the guided drilling procedure and finalize the drill protocol with the freehand protocol after removal of the surgical template. The implant is placed freehand.
1. Incorrectly positioned: too close to or colliding with neighboring teeth or soft tissue
2. Correctly positioned: changed diameter
3. Correctly positioned: changed to pilot sleeve
Vertical collisions are collisions potentially with soft tissue (surface scan of the intraoral situation). If a collision occurs and you have chosen a pilot drilling option, consider adjusting the sleeve offset.

2. Correctly positioned: sleeve offset adjusted
