Trueness of tooth modified scan bodies as a novel technique for edentulous full arch implant supported dental prosthesis: an in vivo prospective comparative study.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06177782 (Accuracy of Tooth Modified Scan Bodies as a Novel Technique for Edentulous Full Arch Implant Supported Dental Prosthesis), which is not on this map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
objectiveThis study aimed to evaluate the clinical performance (degree of trueness) of a novel scan body "tooth-modified Scan body" (TMSB)& conventional scan body (CSB) in implant-supported full arch screw retained cases.
methodsSeven edentulous arches (two maxillae, five mandibles) in 6 patients were rehabilitated with monolithic zirconia screw-retained implant prostheses supported by 4 (n = 1) and 5 implants (n = 6) for a total amount of 34 implants. Implant locations were scanned by intra-oral scanner (IOS) using two types of scan bodies, conventional scan bodies (CSB) in group (1) and tooth-modified scan bodies (TMSB) in group (2). 68 implant positions (representing the total sample size) were captured and compared to the relative reference scans regarding angular and Euclidian deviation (ΔEUC).
resultsThe ΔEUC deviation Of TMSB group had lower values (M = 61.46, SD = 42.12) than that Of CSB group (M = 97.97, SD = 56.69). This difference was statistically significant (p = .005), 95% Confidence interval. The angular deviation of TMSC group had lower values (M = 0.85, SD = 0.69) than that Of CSB group (M = 1.3, SD = 1.06) which was statistically significant (p = .033), 95% Confidence interval. There was a correlation between the type of Jaw and both angular and ΔEUC deviation of both groups, which was statistically significant.
conclusionA tooth-modified scan body (TMSB) may improve the ease and trueness of full-arch implant scanning, even in challenging mandibular arches. CLINICAL TRIAL REGISTRY DATE: Retrospectively registered in 20/ 12/ 2023. CLINICAL TRIAL REGISTRY NUMBER: NCT06177782.
