Articulation can be traditional using a physical articulator; digital using a physical articulator followed by 3D scanning, or virtual using 3D scanning and software to articulate scans without initial physical articulation. This study compared the precision of traditional articulation, using physical centric relation records and an articulator and virtually, by digitally aligning scans of the casts and record. Articulated casts and centric relation records were obtained. 12 record pairs were recorded from the articulated casts. Virtual method all records were scanned, unclamped, in a custom laboratory scanner. The casts were aligned to each scanned record to create virtual articulations. Traditional method each record was used to physically articulate the casts. Each articulation was recorded using an intraoral scanner. The mean inter-arch separation between three key-points on each cast-pair were used to determine differences in occlusal separation in three anatomical directions, and precision of methods. Traditional articulations standard deviations in key-point distance never exceeded 0.102mm. The virtual equivalent was 0.059mm. Statistically significant differences (p⟨0.05) between all anteroposterior separation distances were found between the methods, and in three of six lateral/vertical separations. Virtual articulation was significantly more precise than traditional articulation. COVID-19 has resulted in the cancellation of general anaesthetic procedures including dental extractions (GAX) for children in the UK, exacerbating existing inequalities. There is robust evidence that children from deprived and some ethnic backgrounds are at greater risk of caries and are, therefore, more likely to be affected by cancellations. To identify the impact of, and possible mitigations for, cancelled general anaesthetic procedures on childre
