About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • 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.

Exclusion criteria

  • Smoker's.
  • Non co-operative patients.

Treatment and study plan

Tooth modified scan bodies

Device

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

Conventional scan bodies

Device

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

Primary outcomes

  1. Degree of trueness

    Time frame: Immediately postoperative

    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.
