Orthodontic profiles: John Valentine Mershon

Limits and Possibilities of Orthodontic Treatment of Patients with Skeletal Forms of Sagittal Anomalies

“…Sagittal anomalies of the occlusion of the dentition are found, according to various authors, from 1.2% to 42% of the surveyed. Already in the early stages of bite formation, sagittal anomalies of the occlusion of the dentition are accompanied by significant morphological, functional, and aesthetic disorders [1][2][3][4][5][6][7].…”

Limits and Possibilities of Orthodontic Treatment of Patients with Skeletal Forms of Sagittal AnomaliesSagittal anomalies of the occlusion of the dentition are found, according to various authors, from 1.2% to 42% of the surveyed. Already in the early stages of bite formation, sagittal anomalies of the occlusion of the dentition are accompanied by significant morphological, functional, and aesthetic disorders [1][2][3][4][5][6][7].Recently, methods of temporary skeletal support (anchor plates, miniscrews) have been widely used in orthodontics, which makes it possible to reduce the number of clinical cases requiring the removal of individual teeth or surgical interventions [15][16][17][18][19][20].

Pathophysiology of Demineralization, Part II: Enamel White Spots, Cavitated Caries, and Bone Infection

“…Dr. John Valentine Mershon (1867-1953) was a 1908 graduate of the Angle School of Orthodontia. He trained in an era when heavy forces to move teeth were applied to the labial surfaces of the dentition [132]. Dr. Mershon was concerned that large applied loads were not physiologic, so he invented or at least popularized the use of a removable lingual arch (RLA).…”

Stability of orthodontic correction: preconditions of relapses caused by occlusal forces

“…Клинические проявления этих дисфунк-ций несложно диагностировать, а результат воздействия -спрогнозировать. Особенности формирования зубоче-люстной системы, ограничивающие возможности орто-донтического лечения, приведены нами в одноименной статье [9].…”

“…Feldmann (2014) удовлетворенности ортодонтическим лечением у 110 пациентов в возрасте 16,9±1,78 года была выявлена корреляция (p≤0,001) меж-ду удовлетворенностью результатом и вниманием к паци-ентам во время лечения [5]. Однако в долгосрочной пер-спективе удовлетворенность пациента ассоциируется со стабильностью ортодонтического лечения независимо от начального или конечного состояния прикуса [1,4,9]. 88% из 555 участников исследования, проведенного N. Mollov и соавт.…”
