Treatment guidelines

Guided surgery with drill guides

Key points

Offers many clinical advantages compared to free-hand surgery
More accurate achievement of what has been planned
Matching of the planned/prefabricated dental prostheses
Compatible with flapless surgery
Maximal and not average deviations between the achieved implant position and the planned one, as revealed by clinical reports of the planning system used, should be taken into account

Advantages of a drill guide

Surgery using a drill guide fabricated on the basis of CT scan images transformed by a planning software offers several clinical advantages:

more accurate execution of the planned surgery
eventually a flapless insertion of implants
avoiding anatomical structures within the bone
avoiding bone augmentation procedures by optimizing the use of available jaw bone
prefabrication of (provisional) prostheses allowing for immediate insertion

Considerations

The precision of the transfer is technique-sensitive since a proper positioning of the drill guide towards the bone during surgery is a key issue. Any deviation of the guide will be reflected on all inserted implants. The maximal and not the average deviation between the achieved implant position and the planned one, as revealed by clinical reports of the planning system used, should be taken into account
The surgeon remains responsible and must eventually opt for not following the planning
A limited mouth opening can hinder the insertion of drills. Inserting the drills/implants with tweezers and then attaching the counterangle to them, helps
Some planning softwares allow for the fabrication of drill guides which are placed either on the bone (open flap) or on the mucosa (flapless surgery)
