Abstract
A cast-free approach is described to fabricate an implant-supported interim restoration
by using the postoperative cone beam computed tomography (CBCT) scan to locate the
placed implant. A postoperative intraoral scan was aligned to the postoperative CBCT
scan through a dental implant planning software program. An attached interim abutment
and implant analog complex was then scanned and superimposed on the placed implant
in the postoperative CBCT scan. Once the best alignment was achieved, a virtual cast
was generated, and an interim restoration with bilateral positioning wings was fabricated
on the interim abutment and inserted during the second-stage surgery. This technique
offers a cast-free approach to inserting an implant-supported interim restoration
immediately after the second-stage surgery to guide the healing of the soft tissue
that can minimize chairside time and optimize the clinical workflow.
