Long-term skeletal and dental effects of facemask versus chincup treatment in Class III patients : A retrospective study.

Objectives: To investigate the skeletal and dental changes during chincup versus facemask treatment, to compare the long-term effects of the two appliances, and to document the impact of each on treatment success.

Methods: In all, 61 patients with Class III syndrome were retrospectively analyzed at three examination times: 7.8 ± 1.

Retrospective 25-year follow-up of treatment outcomes in angle Class III patients : Early versus late treatment.

Objectives: To assess early versus late treatment of Class III syndrome for skeletal and dental differences.

Methods: Thirty-eight Class III patients treated with a chincup were retrospectively analyzed. Baseline data were obtained by reviewing pretreatment (T0) anamnestic records, cephalograms, and casts.

Retrospective 25-year follow-up of treatment outcomes in Angle Class III patients : Success versus failure.

Objectives: Despite recommendations for early treatment of hereditary Angle Class III syndrome, late pubertal growth may cause a relapse requiring surgical intervention. This study was performed to identify predictors of successful Class III treatment.

Materials And Methods: Thirty-eight Class III patients treated with a chincup were retrospectively analyzed.

Comparative bond strength of new and reconditioned brackets and assessment of residual adhesive by light and electron microscopy.

An average rate of bracket loss of between 4.7 and 6 per cent is to be expected in daily clinical orthodontic practice during a typical 2 year treatment period. For reasons of economy, detached brackets are commonly reattached after sandblasting to remove adhesive, or replaced with used brackets reconditioned by specialist companies.

In vitro release of phosphoric acid ester from self-etching primer.

Self-etching primers have simplified the process of direct bonding of dental resins, by eliminating the rinsing step after etching in conventional bonding, for example. Although it is generally assumed that all of the applied self-etching primer is incorporated into the resin, the possibility that a substantial amount remains free and extractable into a person's saliva has not been investigated. The aim of the present study was to examine this issue by bonding brackets to extracted teeth with self-etching primers under controlled conditions and determining the proportion of the applied phosphoric acid ester that is subsequently extractable by high-performance liquid chromatography.
