A device for determining the position of at least one of a dental patient's dental midline and incisal plane relative to the patient's facial midline. The device includes an impression/bite tray for obtaining a dental impression of at least one of the patient's maxillary arch and mandibular arch, and a plane indicator including at least one of a vertical alignment bar and a horizontal alignment bar, pivotally mounted to the impression/bite tray for rotatable movement relative to the impression/bite tray. The at least one of the vertical alignment bar and the horizontal alignment bar can be aligned with the dental patient's facial midline and an imaginary plane perpendicular to the facial midline, respectively, by rotating the plane indicator relative to the impression/bite tray while the impression/bite tray is retained in the patient's mouth during positioning and securing of the at least one of a vertical alignment bar and a horizontal alignment bar.
