Midpalatal Suture
The fibrous joint that unites the two palatal bones at the midline of the hard palate, targeted during palatal expansion therapy.
Full Definition
The midpalatal suture (also spelled mid-palatal suture) is a median fibrous articulation running anteroposteriorly through the hard palate. Palatal expansion appliances exploit its relative plasticity during growth to physically separate the two maxillary halves, creating new bone in the gap. Editors must ensure consistent spelling and hyphenation of this anatomical term within a single document. Suture fusion typically begins in late adolescence, which is why expansion is more effective in younger patients. Radiographic assessment of suture maturation guides treatment timing decisions discussed in orthopedic literature.
Usage
Usage note: Both 'midpalatal suture' (one word, no hyphen) and 'mid-palatal suture' (hyphenated) appear in literature; editors should apply consistent house style throughout a document.
In Context
- "Cone-beam CT imaging revealed incomplete fusion of the midpalatal suture, confirming the patient's candidacy for orthopedic expansion." — Radiographic report
- "Opening of the midpalatal suture was confirmed by the appearance of a diastema between the maxillary central incisors." — Clinical observation note
