OBJECTIVE To investigate the determinant factors of discomfort attributed to the use of fixed orthodontic appliance and the effect on the quality of life of adolescents. MATERIAL AND METHODS Two hundred and seventy-two individuals aged between 9 and 18 years old, enrolled in public and private schools and undergoing orthodontic treatment with fixed appliance participated in this cross-section...
Aim: To compare 2 types of treatment for Class II malocclusion assessing mandibular behavior in subjects submitted to full orthodontic treatment with standard edgewise appliance and cervical headgear (Kloehn appliance) and those who used cervical headgear in the first period and with full orthodontic appliance in the second period. Methods: The sample consisted of 80 children treated with eithe...
INTRODUCTION The aim of this study was to evaluate the effectiveness of early orthodontic treatment with the Twin-block appliance for the treatment of Class II Division 1 malocclusion. This was a multi-center, randomized, controlled trial with subjects from 14 orthodontic clinics in the United Kingdom. METHODS The study included 174 children aged 8 to 10 years with Class II Division 1 maloccl...
BACKGROUND During orthodontic treatment, the various elements that constitute the fixed appliance undergo different processes. As a result of a change of the surface, elution/coverage of metals on the surface can be observed in the process of corrosion/passivation. MATERIAL AND METHODS Scanning electron microscopy with an energy-dispersive X-ray analytical system (SEM-EDX) was used to analyze...
INTRODUCTION The placement of fixed orthodontic appliances may lead to increased plaque accumulation and changes in subgingival microflora. OBJECTIVE The aim of this study was to examine the changes in frequency of subgingival microflora that occur after placement and removal of fixed orthodontic appliance using polymerase chain reaction (PCR). METHODS This study included 33 orthodontic pat...
OBJECTIVE A study was designed to determine changes in the amplitude of the EMG muscular activity of the Masseter and Temporalis muscles at clench in children with a Class II, division 1 malocclusion treated with the pre-orthodontic Trainer functional appliance, for 12 months. STUDY DESIGN 36 Class II, division 1 malocclusion patients (mean age 7.6 ± 1.3 years) composed the treated group and ...
INTRODUCTION The first straight-wire appliance was introduced over 40 years ago to increase the consistency and efficiency of orthodontic treatment. More recently, computer-aided design and computer-aided manufacturing (CAD/CAM) technology has been used to create individualized orthodontic appliances. The purpose of this study was to investigate the clinical effectiveness and efficiency of CAD/...
INTRODUCTION The aim of this prospective, longitudinal, case-series study was to analyze the effect of orthodontic treatment by means of an activator appliance on the temporomandibular joint disc-condyle complex. METHODS The sample included 27 consecutively treated subjects with Class II Division 1 malocclussions (21 boys, 6 girls) who underwent orthodontic therapy with activators. The averag...
Moses describes an appliance termed a "passivator" which supports the mandible in an anterior and slightly open bite yet neither allows nor causes undesirable orthodontic tooth movements. This appliance is reported to support the patient’s mandible during sleep, prevent collapse of the pharyngeal musculature, allow greater volume of space for tongue activity and prevent incorrect swallowing and...
The Hybrid Aesthetic Functional (HAF) Appliance: A Less Visible Proposal for Functional Orthodontics
In modern orthodontics, aesthetics appear to have a decisive influence on orthodontic appliance preferences and acceptability. This paper reports the early application of a newly emerged functional device with enhanced aesthetics in a Class II treatment. Patient perspectives and technical considerations are discussed along with recommendations for further design development. It can be assumed t...
