Implants require more precise impressions than crowns and bridges because implants lack a periodontal ligament to compensate for inaccuracies. It is critical to accurately record the three-dimensional position, angulation, and depth of implants to obtain a proper fitting definitive restoration. Making high quality impressions at the implant or abutment level is necessary to successfully fabricate implant prostheses.

It is more critical to record 3- dimensional
position of the implants as they occur
intraorally.
Accurate recording of spatial implant position
is required to obtain a proper support to
definitive restoration with passive fitting.
Natural teeth have a PDL to compensate for
minor inaccuracies while implants have not.
