About this study
Official title: Trueness of Full-Arch Impressions Using Photogrammetry, Splinted Digital Scan Bodies Versus Conventional Open-Tray Techniques in the All-on-x Prosthesis
This study aims to compare the trueness and precision of three impression methodologies photogrammetry, digital intraoral scanning with splinted scan bodies, and conventional open tray impressions in the context of the All-on-X treatment concept. This will provide valuable evidence for clinicians considering digital workflows for implant-supported prostheses. Does the use of photogrammetry and digital impression techniques with splinted scan bodies result in improved accuracy in implant position transfer in the All-on-X concept compared to conventional open tray impressions?
- Conditions
- Truness of Impression Techniques in All on x Cases, Trueness of Full Arch Implant Prosthesis Impression
- Being tested
- photogrammetry based full arch impression, Digital Impression Using Splinted Scan Bodies, Conventional Open-Tray Implant Impression
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
photogrammetry based full arch impressionDevice
use of photogrammetry system to capture the positions of All on X implants digitally without physical impression material. This technique aims to achieve precise measurements and increase patient satisfaction
Digital Impression Using Splinted Scan BodiesDevice
Digital full-arch impression using splinted scan bodies connected with resin to enhance stability. An intraoral scanner captures the splinted assembly for framework fabrication. Accuracy and patient satisfaction will be evaluated.
Conventional Open-Tray Implant ImpressionProcedure or surgery
Traditional full-arch open-tray impression using polyether or VPS material with splinted impression copings. This serves as the standard comparator for evaluating accuracy and patient satisfaction.
| Study group | Role | What they receive |
|---|---|---|
| photogrammetry based full-arch impression | Experimental | Not described Receives: Device: photogrammetry based full arch impression |
| Digital impression using splinted scan bodies | Experimental | Not described Receives: Device: Digital Impression Using Splinted Scan Bodies |
| conventional open tray implant impression | Active comparator | Not described Receives: Procedure: Conventional Open-Tray Implant Impression |
What is being measured
The primary outcome is the main question the study is designed to answer.
Accuracy measured using 3D inspection software (Geomagic Control X).
Measured: Immediately after measurements taking
Secondary outcomes (1)
Oral health-related quality of life (OHRQoL), assessed using standardized questionnaires.
Measured: immediately after measurements taking

What does the primary outcome measure?
Accuracy measured using 3D inspection software (Geomagic Control X). (time frame: Immediately after measurements taking). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07550725, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
