The effects of functional therapy on sagittal pharyngeal dimensions in subjects with sleep-disordered breathing and a class II malocclusion

AIM: To evaluate the craniofacial changes induced by functional treatment of mandibular advancement with special regard to the pharyngeal sagittal airway dimensions, tongue and hyoid bone position in subjects with sleep-disordered breathing (SDB) and a dentoskeletal Class II malocclusions when compared with an untreated Class II control group.

SUBJECTS AND METHOD: Fifty one subjects (24 females,

Geometric morphometric analysis of maxillary morphology in children with impacted incisors – a three-dimensional evaluation

AIM: To analyze variations in palatal morphology in subjects presenting with unilaterally impacted maxillary permanent central incisors (IIG) compared with a control group (CG) of subjects without eruption anomalies using three-dimensional (3D) analysis.

METHOD: Twenty-six Caucasians (10 females, 16 males; mean age 9.5 ± 1.5 years) with IIG were compared with a CG of 26 subjects (14 females,

A systematic approach for interproximal enamel reduction: in-vitro and in-vivo evaluation of diamond coated strips

Aim: to test in vitro and in vivo the wear performance of diamond coated strips by means of Tribological test and Scanning Electronic Microscope (SEM).

Materials and Methods: To evaluate the in-vitro wear performance, a Tribological test was performed by a standard Tribometer. The abrasive strips slid against stationary freshly extracted premolars fixed in resin blocks,
