# §872.3220. Facebow.

- (a) **Identification.** A facebow is a device intended for use in denture fabrication to determine the spatial relationship between the upper and lower jaws. This determination is intended for use in placing denture casts accurately into an articulator ([§ 872.3150](/cfr/21/872.3150.md)) and thereby aiding correct placement of artificial teeth into a denture base.
- (b) **Classification.** Class I (general controls). The device is exempt from the premarket notification procedures in [subpart E of part 807](/cfr/21/part807-subpartE.md) of this chapter subject to the limitations in [§ 872.9](/cfr/21/872.9.md). If the device is not labeled or otherwise represented as sterile, the device is exempt from the current good manufacturing practice requirements of the quality management system regulation in [part 820](/cfr/21/part820.md) of this chapter, except for requirements concerning records and complaint files under [§ 820.35](/cfr/21/820.35.md) of this chapter.
