Enter your measurements. The checklist compares them with the guide values Dr Hajtó teaches in his bite-raising course and shows the source for each value.

Does not replace functional analysis, model analysis or clinical judgement.
Guide value: 19 ± 1 mm (18–20 mm) from the CEJ of the upper central incisor to the CEJ of the lower central incisor, measured in occlusion.

Guide value: 0.5–3.5 mm upper incisal display with the lips relaxed.

Raising up to 5 mm (incisal) is considered safe; the system adapts. Mild transient symptoms are possible, mostly self-limiting.
Conversion on the lateral ceph (taught by Dr Hajtó): 1 mm at the anterior teeth ≈ 1° rotation; 2 mm at the incisal pin ≈ 1° rotation.

Each criterion is compared on its own with its guide value and shown as “within range”, “below”, “above” or “not entered”. A value exactly on a limit (for example 0.5 or 3.5 mm) counts as within range; a planned raise of exactly 5 mm does not trigger the warning.
Criteria: the Shimbashi distance from CEJ to CEJ in occlusion (18–20 mm), upper incisal display at rest (0.5–3.5 mm), the lower incisal edge above the lip line (1–1.5 mm), clinical crown length of premolar/first molar (6–7 mm) and the planned raise at the incisors (warning above 5 mm). For the Shimbashi distance the checklist shows the raise this criterion suggests; for the planned raise, the approximate rotation after Dr Hajtó's rule of thumb.
The checklist adds nothing up: it does not compute a combined “ideal” raise, and it does not convert the crown length missing at a posterior tooth into a value at the incisors.
The guide values are taken from Dr Jan Hajtó's courses (marked “Taught by Dr Hajtó”, with the course chapter). Where the literature gives other values, Dr Hajtó's value is shown. Papers whose abstract agrees are listed with their PMID.

Five measurements: the Shimbashi distance from CEJ to CEJ (19 ± 1 mm), upper incisal display with the lips relaxed (0.5–3.5 mm), the lower incisal edge above the lip line (1–1.5 mm), the clinical crown length of premolar/first molar (6–7 mm) and the planned raise at the incisors (warning above 5 mm). It adds notes on functional findings, the Dahl principle and printed occlusal build-ups, the seven steps and the time planning.
Dr Hajtó teaches 19 ± 1 mm from the CEJ of the upper central incisor to the CEJ of the lower central incisor in occlusion. For a measured distance x the checklist shows a raise of (18 − x) to (20 − x) mm, never below 0. At 20 mm or more this criterion suggests no raise. It is one criterion among several (18–20 mm), not an ideal value.
Dr Hajtó teaches that a raise of up to 5 mm at the incisors is considered safe. Abduo and Lyons (2012) state in their abstract that a maximum increase of 5 mm can be justified. Above 5 mm the checklist shows a warning.
Dr Hajtó's rule of thumb on the lateral ceph: 1 mm at the anterior teeth ≈ 1° rotation, 2 mm at the incisal pin ≈ 1° rotation. For a planned incisal raise the checklist shows the approximate degrees.
The criteria describe different things: the anterior length, the incisal edges, the posterior crowns and a safety limit. Each one is shown on its own; the decision stays with the clinical planning, including functional and model analysis.
Dr Hajtó plans 2–3 months for the splint and 2–3 months for the occlusal build-ups. Printed build-ups should stay in place no longer than 6–12 months; Doumit et al. (2025) followed 352 printed restorations and found wear over 0.5 mm in 35 % after 24 months.
Dr Hajtó teaches not to raise more than 2 mm at once with the Dahl principle (risk of tongue interposition), not to use it with TMJ problems or tongue dysfunction, and that it works faster the younger the patient. Above 2 mm with the Dahl method the checklist shows a warning.
