Outcome Measures
Primary Outcomes (1)
Degree of trueness
Digital files will be obtained: either conventional scan or TMSB scan. All the STL files will be imported to dental CAD software , and scan bodies will be converted to implant multi-unit ti-base replicas using a digital library. Then, updated STL files will be imported to inspection software for trueness assessments.
Immediately postoperative
Study Arms (2)
Tooth Modified Scan Bodies
ACTIVE COMPARATORThe 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.
Conventional Scan Bodies
PLACEBO COMPARATORThe intraoral scanner (IOS) impression will be recorded using conventional implant scan bodies secured at the multiunit abutment level.
Interventions
Tooth modified scan bodies are used during scanning for full arch implant cases.
Conventional scan bodies will be used for scanning the full arch implant cases.
Eligibility Criteria
You may qualify if:
- Participants who had received 4-6 implants in 1 edentulous arch.
- Participants with 1-piece implant-supported complete-arch fixed dental prostheses.
- Systemically free.
- Primary implant stability exceed 72 the day of the definitive impression.
You may not qualify if:
- Smoker's.
- Non co-operative patients.
