Role of scan body material and shape on the accuracy of complete arch implant digitalization
Purpose: The aim of the study was to evaluate how the intraoral scan body (SB) material and shape affects the scanning accuracy and scan time in completely edentulous situations since it is not well understood. Methodology: Two SB systems were evaluated: SB-1 group (Polyetheretherketone (PEEK)/Flag...

| description | Purpose: The aim of the study was to evaluate how the intraoral scan body (SB) material and shape affects the scanning accuracy and scan time in completely edentulous situations since it is not well understood.
Methodology: Two SB systems were evaluated: SB-1 group (Polyetheretherketone (PEEK)/Flag shaped, Biohorizon, USA), and SB-2 group (Titanium/cylindrical shape, Bioline, GmbH). On completely edentulous mandibular model with 4 dental implants (TMR 4.6, Biohorizon, USA) with scan bodies were positioned in the first molar and canine. The model was scanned using a calibrated laboratory scanner (D2000; 3Shape) to generate a master reference model (MRM). Ten consecutive digital impressions Standard Tessellation Language file were made of the model using an intraoral scanner (Trios, 3Shape A/S) for both the test groups. The test scans were superimposed over the MRM using a best-fit algorithm, and then, the distance deviation and angular deviation of the scan bodies were calculated. Scan time was also recorded. Mann–Whitney U-test was used to statistical analysis. P > 0.05 considered statistically significant.
Results: Statistically significant differences were found between the SB material and shape on the linear measurement, angular deviation, and scan time (P < 0.05). The SB-1 group achieved higher accuracy overall and also exhibited noticeably lower scan time.
Conclusion: The quality of digital intraoral impressions seems to be influenced by both the geometry and material of the SB. For clinical practice, the PEEK material seems clinically beneficial for decision-making. |
