Bolton Analysis: Understanding Tooth Size Discrepancy in Orthodontic Planning Achieving ideal occlusion requires more than proper tooth alignment—it depends on precise proportional relationships between the maxillary and mandibular teeth. One of the most important tools for evaluating these relationships is the Bolton Analysis, a diagnostic method used to identify tooth size discrepancies that can interfere […]
Subapical Osteotomy: Technique, Indications, and Surgical Considerations A subapical osteotomy is a dentoalveolar surgical procedure used to reposition a segment of the anterior mandible while preserving the integrity of the basal bone and inferior alveolar nerve. This technique is most commonly indicated for the correction of dentoalveolar deformities that cannot be adequately managed with orthodontics

The Steiner analysis is a cephalometric analysis useful in evaluating the degree of maxillary and mandibular incisor protrusion relative to the surrounding skeletal structures. The position of the maxillary and mandibular incisors is related to Nasion-A point (N-A) and Nasion-B point (N-B) lines using both angular and linear measurements.

History of Bilateral Sagittal Split Osteotomy 1907: Blair described a completely horizontal osteotomy. Straight across. 1942: Schuchardt modified the buccal osteotomy to be 10mm inferior to the lingual osteotomy; dotted line indicates Blair’s original horizontal osteotomy. 1953-1957: Trauner/Obwegeser further increased the distance between buccal and lingual osteotomies from 10mm to 25mm, thus pioneering the original sagittal split osteotomy. 1961: Dal Pont advanced the buccal osteotomy

Anterior > posterior When >10mm expansion required Requires osteotomies where potential resistance to lateral expansion will be encountered Palatal suture, lateral buttresses, and pterygomaxillary junction During surgically assisted rapid palatal expansion (SARPE), there is greater widening within the anterior maxilla than there is posteriorly. By contrast, a segmental osteotomy will produce more expansion posteriorly than
