Statement of problemIntraoral scanners (IOSs) provide a digital alternative to conventional implant impression techniques. However, the effect supramucosal height scan body and angulation on accuracy IOSs remains unclear.PurposeThe purpose this in vitro study was measure impact (trueness precision) intraoral scans partially edentulous models.Material methodsTwo maxillary casts with 4 analogs were fabricated, 1 parallel implants (P-groups) 2 distally inclined 18 degrees (A-groups). An...
There is a paucity of comparative clinical studies assessing the accuracy full-arch digital scans versus conventional implant impressions. The aim this retrospective study was to compare three-dimensional (3D) deviations between and impressions for edentulous maxillae mandibles.Twenty-seven patients (36 jaws) were treated with one-piece, screw-retained implant-supported fixed complete dental prostheses (IFCDPs). Twenty-one jaws maxillary, 15 mandibular. Full-arch intraoral scan bodies an...
The purpose of this clinical report is to present a complete digital workflow for the fabrication arch fixed zirconia implant restorations. An intraoral scanner was used capture implants' position at abutment level and also patient's existing interim prostheses with double scanning technique. A novel scan body impression pin were utilized throughout process which allowed accurate reproducible superimposition generated Standard Tesselation Language (STL) files. Prosthesis prototypes digitally...
To assess the accuracy of fit complete-arch printed prosthesis prototypes generated with a digital workflow protocol for completely edentulous jaws.Forty-five jaws (35 patients) underwent intraoral scans double scanning (DDS) technique and standard tessellation language (STL) files were superimposed imported into computer-aided design software. After STL merging, each master file was used printing prototype. The primary outcome assessment on verified stone casts. Two experienced clinicians...
To assess the accuracy of template-guided implant surgery for edentulous arches.The stone master casts 25 arches treated with either 4 or 6 implants CBCT generated were included in this observational cohort study. The from surgical templates (group one) prior to placement digitized into Standard Tesselation (STL) files a reference scanner. For comparison, derived intraoral complete-arch impressions after two) also digitized. resultant STL superimposed and best-fit-alignment algorithm was...
