Abstract:
A method for making an intraoral x-ray film packet comprising the steps of:(a) forming a first outer sheet having a tensile modulus of at least 700 Kg/cm2 from a thermoplastic material; (b) forming a second outer sheet; (c) sealing the first outer sheet and the second outer sheet together to form an envelope with a laminated perimetric edge, the envelope containing a film chip, the laminated perimetric edge being substantially coplanar with the first outer sheet; (d) transporting the intraoral x-ray film packet to a Bernoulli fixture having angled air holes disposed in a substantially planar surface thereof to generate a laminar air flow across the surface thereof; and (e) moving the intraoral x-ray film packet along the surface to accurately position the intraoral x-ray film packet against reference stops disposed in the surface using the Bernoulli effect.
