Skeletal and dental outcomes of a new magnetic functional appliance, the Sydney Magnoglide, in Class II correction.

Introduction: The purpose of this prospective study was to evaluate the dentoskeletal effects of a new magnetic functional appliance, the Sydney Magnoglide (Macono Orthodontic Lab, Sydney, Australia), after both active treatment with the appliance and comprehensive fixed appliance therapy, compared with a group of untreated Class II controls.

Methods: Thirty-four consecutively treated Class II Division 1 patients treated with the Sydney Magnoglide followed by fixed appliances were compared with 30 untreated Class II controls with the same initial dentoskeletal Class II features and matched for age and sex. Lateral cephalograms were taken before treatment, immediately after functional appliance therapy, and after comprehensive fixed appliance therapy.

A controlled study on diagnostic and prognostic measurements of palatally displaced canines on lateral cephalograms.

Objectives: The aim of this prospective controlled study was to determine the role that the lateral cephalogram can play in the detection of palatally displaced canines (PDCs).

Materials And Methods: The study was comprised of 85 subjects in the late mixed dentition. Thirty-five subjects had PDCs (either unilateral or bilateral) identified on the panoramic radiograph (PDC group), and 50 subjects presented with a normal pathway of upper permanent canine eruption as assessed on panoramic radiographs (No-PDC group).

Treatment timing of MARA and fixed appliance therapy of Class II malocclusion.

The objective of this study is to evaluate the effect of timing on Mandibular Anterior Repositioning Appliance (MARA) and fixed appliance treatment of Class II malocclusion in a prospective clinical trial. The treated sample consisted of 51 consecutively treated patients at prepubertal (n = 21), pubertal (n = 15), and postpubertal (n = 15) stages of development. Control groups for the three treated groups were generated from growth data of untreated Class II subjects.

Mandibular second molar eruption difficulties related to the maintenance of arch perimeter in the mixed dentition.

Introduction: In this prospective longitudinal study, we compared the prevalence of mandibular second molar eruption difficulties in patients treated with appliances to maintain mandibular arch perimeter. Other independent variables (age, molar angulation, space-width ratio, treatment time, and sex) were tested for their value as predictors of eruption difficulty.

Methods: Three hundred one patients and subjects were divided into 4 groups: patients treated with a Schwarz appliance, patients treated with a mandibular lingual holding arch, patients treated with a combination of both appliances, and subjects who received no treatment (controls).

Healing of gingival recession following orthodontic treatment: a 30-year case report.

This case report describes the healing of gingival recessions on mandibular incisors resulting from orthodontic treatment of a deep bite malocclusion at a 30-year follow-up observation. The marked improvement in the severe recessions was a consequence of the elimination of the direct trauma, orthodontic intrusion of the affected teeth, and subsequent creeping attachment over time. No periodontal treatment was performed before or after orthodontic treatment.

Prevalence rate and dentoskeletal features associated with buccally displaced maxillary canines.

The aim of the study was to analyse the prevalence and distribution of buccally displaced canines (BDCs) in subjects scheduled for orthodontic treatment and to investigate the association between BDC and sagittal, vertical, and transverse dentoskeletal relationships. A study sample of 1852 subjects was examined, and it was divided randomly into two groups. A first group of 252 subjects served as control group: the 'reference' prevalence rates for the examined parameters were calculated in this group.

Dentition phase and chronological age in relation to gingival crevicular fluid alkaline phosphatase activity in growing subjects.

Objective: Identification of skeletal maturation phases is of primary importance in terms of individual responsiveness to nearly all dentofacial orthopaedic treatments. In this regard, dentition phase and chronological age are still widely used to define the timing of and responsiveness to orthodontic treatments. Recently, gingival crevicular fluid (GCF) alkaline phosphatase (ALP) activity has been shown to be a reliable biomarker of skeletal maturation in growing subjects.

Efficacy of 2 finishing protocols in the quality of orthodontic treatment outcome.

Introduction: The objectives of this prospective clinical study were to evaluate the quality of treatment outcomes achieved with a complex orthodontic finishing protocol involving serpentine wires and a tooth positioner, and to compare it with the outcomes of a standard finishing protocol involving archwire bends used to detail the occlusion near the end of active treatment.

Methods: The complex finishing protocol sample consisted of 34 consecutively treated patients; 1 week before debonding, their molar bands were removed, and serpentine wires were placed; this was followed by active wear of a tooth positioner for up to 1 month after debonding. The standard finishing protocol group consisted of 34 patients; their dental arches were detailed with archwire bends and vertical elastics.
