Immediate digital impression and accuracy revaluation of inhouse surgical stent.

Posted on By armando ponzi In CBCT & CAD/CAM

Patient needed an implant restauration on tooth 36. Bone availability allowed the placement of a large diameter implant (6x11.5). An inhouse surgical stent was produced by a digital planning.
A CBCT and a digital impression of the patient were ‘superimposed’ to obtain surgical stent profile: in yellow is shown the prolongation of implant over the prosthetic area.
Once implant was inserted a scan transfer and a digital impression were immediately taken and data used either to design a custom abutment & crown and for revaluating the accuracy of stent : this impression was superimposed over the virtual project and give insight about stent accuracy.
The stent used did not have implant insertion control but you can appreciate the high level of accuracy.
IMO, if data and project are accurate, the end result can be widely,easily achievable and predictable.
Any opinion about it?

Planning:cross section
Planning: restorative spaces (yellow)

Minimally invasive implant site
Digital scanning right after implant insertion
