Full description

The clinical performance of a novel scan body Tooth Modified Scan Body (TMSB) in the degree of trueness of IOS impression for full arch cases. TMSB is a scan body to which different teeth are attached directly as one piece, this may enhance the accuracy level by filling the gabs between ISB as well as acting as a stable artificial AI-easily recognized landmarks thus facilitating the scanning procedure. OS impression utilizing tooth modified scan bodies or conventional scan bodies result in the same degree of trueness as conventional verified splinted open tray impression. To our knowledge, it is the first time in the literature to utilize a novel scan body modified with directly connected teeth as artificial landmarks in vivo.

60 participants in 2 patient groups, including a placebo group

Tooth Modified Scan Bodies

Active Comparator group

Description:

The intraoral scanner (IOS) impression will be recorded using modified scan bodies. The IOS device will be calibrated right before the impression. The scan strategy will be consistent for all the procedures following the manufacturer guidelines.

Treatment:

Device: Tooth modified scan bodies

Conventional Scan Bodies

Placebo Comparator group

Description:

The intraoral scanner (IOS) impression will be recorded using conventional implant scan bodies secured at the multiunit abutment level.

Treatment:

Device: Conventional scan bodies
