High arched palate can be created by 2 sequences:

/s/ distortions are common but have many possible causes:

anterior open bite
Intra arch relationship refers to how the _____ and ______ teeth fit with one another.
3 intra arch relationships:
Anterior-posterior: Class I
Maxillary arch fits over mandibular arch by a half tooth; max arch is slightly wider.
Othodontics can still be necessary with normal occlusion
Anterior Posterior: Class II, Division 1
The maxillary first molars are forward from their normal position, relative to mandibular.
Max arch is narrowed and lengthened
Anterior Posterior: Class II, Division 2
Central incisors are retruded and
lateral incisors are tipped labially and medially
Posterior Anterior: Class III
-Open bite-/s/ /z/ /ch/ /j/ distortions
Unilateral Posterior open bite is common in hemifacial microsomia.
Caused by incomplete eruption
-deep bite-mandibular teeth are almost hidden behind max
