To evaluate the impact of reducing radiographic field view (FOV) on trueness and precision alignment between cone beam computed tomography (CBCT) intraoral scanning data for implant planning.Fifteen participants presenting with one three clinical scenarios: single tooth loss (ST, n = 5), multiple missing teeth (MT, 5) presence artifacts (AR, were included. CBCT volumes covering full arch (FA) reduced to quadrant (Q) or adjacent tooth/teeth (A). Two operators, an expert (exp) in virtual planning inexperienced clinician, performed superimpositions, FA-exp serving as a reference. The deviations calculated at apex shoulder levels. Thereafter, linear mixed models adapted investigate influence FOV discrepancies.Evaluation compared resulted largest mean (AR-A: 0.10 ± 0.33 mm) maximum discrepancy (AR-Q: 1.44 artifacts. Furthermore, ST group, error (-0.06 0.2 mm, shoulder) was FA-FOV, while MT, intermediate volume (-0.07 0.24 Q). In terms precision, SD intervals ≤0.25 mm (A-exp). Precision influenced by (FA < Q A) but not operator expertise.For posterior teeth, extended does improve registration accuracy. However, caution is recommended when FOV.
