Long-term effect on adenoid dimensions and craniocervical angulation after maxillary expansion with fixed or functional appliances
Background Maxillary expansion is a common orthodontic procedure that could have a positive effect also on airway patency. The aim of the present study was to evaluate the long-term effects of rapid maxillary expansion (RME) on nasopharyngeal area and cranio-cervical angulation in growing patients, compared to controls treated with a function-generating bite appliance (FGB). Material and methods Sixty patients aged 6-14 consecutively treated with RME or FGB were selected retrospectively and divided into two groups. Lateral cephalograms taken before and after treatment were retrieved, and the nasopharyngeal area, delimited superiorly by a sella-posterior nasal spine (PNS) line and inferiorly…
Post-orthodontic position of lower incisors and gingival recession: A retrospective study
Background To evaluate if changes in lower incisor position following orthodontic treatment are correlated with development of gingival recessions. Material and methods Pre- and post-treatment digital models and lateral cephalograms of 22 subjects were collected retrospectively. The clinical crown length, gingival scallop, and papilla height of the central lower incisor were measured along with the cephalometric incisor's inclination, the distance from the mandibular plane, and the distance between the Infradentale and Menton points. Statistical correlations between gingival and cephalometric variables were studied. In addition, two groups were defined based on the post-treatment incisor in…
Trattamento funzionale delle latero-deviazioni mandibolari
Riassunto Obiettivi Analizzare le possibilita di intervento della placca funzionale di Cervera-Bracco nella correzione delle latero-deviazioni mandibolari e valutarne l’efficacia nel modificare un pattern di crescita sfavorevole. Materiali e metodi Sono stati esaminati 22 casi di latero-deviazione mandibolare che presentavano una deviazione della linea mediana inferiore determinata da una contrazione monolaterale del mascellare superiore. I casi sono stati esaminati al termine della fase di trattamento funzionale, durata da 12 a 24 mesi. Risultati Al termine della prima fase di trattamento funzionale, 18 pazienti su 22 esaminati presentavano una correzione della linea mediana inferiore conf…
Determinants of maxillary canine impaction : retrospective clinical and radiographic study
Background: The aim of this study is to evaluate determinants of maxillary canine impaction taking into account both canine position related variables and the pattern of facial growth. Material and Methods: A retrospective clinical and radiographic analysis was carried out on 109 patients aged between 9 and 10 years at the time of first evaluation. At baseline, SN-GoMe angle, the interincisal angle, the canine angle a and the canine distance d were used to characterize canine location and vertical facial growth. At the end of a two years follow up period the eruption state of each canine of each patient was recorded and accordingly classified as erupted or impacted on a clinical and radiogr…
