OBJECTIVES The aim of this study was to compare bond failure and breakage rates of two types of bonded lingual orthodontic retainers (GFR and .0175" multistranded stainless steel wire [MST]) after a 6-year retention period. SUBJECTS AND METHODS Eighty-five young adults were randomly divided into two groups: 40 subjects received 48 GFR retainers (14(More)
OBJECTIVES To perform a literature review focusing on the use of non-compliance intraoral appliances for molar distalization therapy. MATERIALS AND METHODS A literature search ranged from January 1999 to December 2009 in order to describe dento-alveolar changes and skeletal vertical modifications following the use of conventional anchorage intraoral(More)
OBJECTIVES The purpose of this retrospective prolective study is to evaluate soft tissue, dentoalveolar and skeletal vertical changes following conventional anchorage molar distalization therapy in adult patients. MATERIALS AND METHODS Forty-six patients (34 females, mean age 25 years 6 months; and 12 males, mean age 28 years 4 months) were recruited from(More)
OBJECTIVE To describe the molar movements and skeletal changes associated with Pendulum-fixed appliance treatment and the long-term postretention period. SUBJECTS AND METHODS The treatment sample consisted of 76 Class II patients, 35 males and 41 females. Lateral cephalograms were obtained at the start of treatment (T1); the end of distalization (T2); the(More)
BACKGROUND There are controversial opinions about the effect of erupted second molars on distalization of the first molars. Most of the distalizing devices are anchored on the first molars, without including second molars; so, differences between sequentially distalize maxillary molars (second molar followed by the first molar) or distalize second and first(More)
OBJECTIVE To compare two distalizing devices supported by palatal miniscrews, the MGBM System (MGBM) and the Distal Screw appliance (DS), in dental Class II patients. MATERIALS AND METHODS Pretreatment (T1) and postdistalization (T2) lateral cephalograms of 53 Class II malocclusion subjects were examined. MGBM consisted of 29 patients (16 males, 13(More)
OBJECTIVE To compare dentoalveolar and skeletal changes produced by the pendulum appliance (PA) and the distal screw appliance (DS) in Class II patients. METHODS Forty-three patients (19 men, 24 women) with Class II malocclusion were retrospectively selected for the study. Twenty-four patients (mean age, 12.2 ± 1.5 years) were treated with the PA, and 19(More)
This case report describes the surgical-orthodontic guided-eruption of a deeply impacted macrodontic maxillary central incisor in a 10-year-old patient with Alagille syndrome (ALGS). In the first stage, orthodontic treatment with fixed appliance on deciduous teeth allowed to create enough space for the eruption of the maxillary right central incisor. The(More)
