Trueness of tooth modified scan bodies as a novel technique for edentulous full arch implant supported dental prosthesis: an in vivo prospective comparative study
Abstract Objective This 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. Methods Seven edentulous arches (two maxillae, five mandibles) i...

| description | Abstract Objective This 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. Methods Seven 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). Results The 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. Conclusion A tooth-modified scan body (TMSB) may improve the ease and trueness of full-arch implant scanning, even in challenging mandibular arches.
