Opening bite more than 2mm
- 3mm is the maximum we will open in the laboratory w/o an open bite record being returned for verification. More than 3mm must be established clinically with CR bite, or through splint therapy. We can assist via our special JC Try‐In Repositioning Device.
- Tip: if distance between #9 & #24 gingival zeniths is less than 17mm (Shimbashi rule) then opening may be needed. Same if intervestibular is less than 35mm.
