Detailed 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.

Conditions

Digital Technology; Dental

Study Design

• Allocation Method: NON_RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Tooth Modified Scan Bodies

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.

Group Type: ACTIVE_COMPARATOR

Tooth modified scan bodies

Intervention Type: DEVICE

Tooth modified scan bodies are used during scanning for full arch implant cases.

Conventional Scan Bodies

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

Group Type: PLACEBO_COMPARATOR

Conventional scan bodies

Intervention Type: DEVICE

Conventional scan bodies will be used for scanning the full arch implant cases.

Interventions

Tooth modified scan bodies

Tooth modified scan bodies are used during scanning for full arch implant cases.

Intervention Type: DEVICE

Conventional scan bodies

Conventional scan bodies will be used for scanning the full arch implant cases.

Intervention Type: DEVICE
