Angle Classification of Malocclusion
Classifies dental occlusion relationship for orthodontic diagnosis and treatment planning

When it activates
Scribeable activates a calculator from the encounter. The Angle Classification of Malocclusion can activate when the transcript or pasted chart context documents any of these:
- Malocclusion classification
- Orthodontic assessment
- Dental occlusion evaluation
- Bite relationship assessment
- Orthodontic treatment planning
A coded diagnosis can also activate it. ICD-10 prefixes carried by the registry: M26.2.
Note-type scope: it activates on notes whose subject resolves to orthodontic, dental. A note that resolves to another subject does not carry it even when the clinician's specialty matches; a note with no resolvable subject (a generic consultation) falls back to the specialty match.
Inputs the note needs
1 input. Each is resolved from the transcript, the pasted chart context and charted labs; at this calculator’s tier a missing input is never requested, and a missing required input keeps the score out of the draft.
| Input | Type | Unit / options | Guidance |
|---|---|---|---|
| Angle classification: Class I, Class II Division 1, Class II Division 2, or Class III | exam |
Scoring
Based on mesiobuccal cusp of maxillary first molar relative to buccal groove of mandibular first molar. Class I: Normal molar relationship (mesiobuccal cusp of upper first molar aligns with buccal groove of lower first molar) with crowding/spacing/rotations. Class II Division 1: Mandible retrognathic, upper incisors proclined (increased overjet). Class II Division 2: Mandible retrognathic, upper incisors retroclined (deep bite). Class III: Mandible prognathic, lower incisors ahead of upper (underbite).
Interpretation
Class I (~50-55%): Skeletal relationship normal — treatment focuses on alignment, crowding/spacing. Class II Div 1 (~15-20%): Often treated with functional appliances in growing patients, or extraction/surgery in adults; significant overjet increases trauma risk. Class II Div 2 (~3-5%): Deep bite management critical, often complex mechanics needed. Class III (~3-5%): Interceptive treatment (reverse-pull headgear/expansion) in growing patients; orthognathic surgery often needed in adults. Does not capture vertical or transverse problems — supplement with skeletal classification.

How Scribeable handles it in the note
When an encounter activates the Angle Classification of Malocclusion (its highest tier is recommended), Scribeable does not ask you for missing inputs. The score is computed in code from whatever inputs resolve from the transcript, the pasted chart context or charted labs; a computed value is written into the draft only when every required input already resolves.
The score is computed in code from the resolved inputs, not recalled by the language model. A stated Angle Classification of Malocclusion value is compared against the computed one when the draft's structured summary carries it; a disagreement found there is flagged to the second drafting pass, which is instructed to correct the score and its interpretation, unless Scribeable has supplied the computed value to that pass, in which case the value the draft writes is checked against the supplied one and a detected difference is shown beside the note for you to adjudicate rather than silently rewritten.
Classified as a staging or classification system: activated strictly, because a wrong stage on the wrong patient is a documentation hazard.
