VPS Is radio opaque, a small impression (or a full arch impression) worn during CBCT scanning allows visualization of the soft tissues in relation to the bone. Transfer to the cast is simple

A small VPS bite registration material impression can be made if the patient has to go to an external radiology center. If the CBCT is in the office, then a scan can be made while the full mouth VPS impression is still in the patients mouth, even if the impression is still setting, so no time is lost. Note ; these images are from another patient. Copyright Š 2011 Idondivi, Inc. All rights reserved

BLP’s in place. The BLP will lock in the bucco- lingual position and the top of the implant. It still allows precision adjustments to the mesio-distal placement

Implant placement. Note that because the ridge was not flattened as is common in non guided surgery the implant # 20 appears to be placed deep. This is however exactly as planned to get adequate buccal bone coverage. The guided bone-mill is used to create space to place the healing caps. The body will resorb as needed.
