OBJECTIVE To evaluate the anteroposterior short-term skeletal and dental effects on Class II malocclusion in growing patients following treatment with functional appliances (activators or twin block), extraoral traction, or combination appliances (appliances with both functional and extraoral traction components), based on published data. MATERIALS AND METHODS A literature search was carried ...

o bjectives: this study sought to assess distal and lateral forces and moments of asymmetric headgears by variable outer bow lengths. materials and methods : four 3d finite element method (fem) models of a cer- vical headgear attached to the maxillary first molars were designed in solidworks2010 software and transferred to ansys workbench ver. 11 software. modelscontained the first molars, thei...

o bjectives: headgears are among the effective orthodontic appliances to achieve treatment goals. unilateral molar distal movement is sometimes needed during an orthodontic treat- ment, which can be achieved by an asymmetric headgear. different unilateral headgears have been introduced. the main goal of this study was to analyze the force system of uni- lateral expanded outer bow asymmetric hea...

BACKGROUND Thumb sucking habits make up the majority of oral habits. While thumb sucking is considered normal during the first two years of life, if it is not controlled and persists beyond the preschool period it may cause deleterious effects on dentofacial structures. Reminder therapy using Bluegrass appliance has been proven successful to intercept thumb sucking habit. CASE REPORT We prese...

Foramen of Winslow herniation is a rare occurrence with a high mortality; it presents a diagnostic challenge with subtle clinical and radiological features. We present a case of caecal herniation through the foramen of Winslow creating a closed loop obstruction which remained undiagnosed until laparotomy. Reduction was achieved with gentle traction after first decompressing the caecum whilst st...

The introduction of percutaneous osseointegration biotechnology in 1979 to head and neck reconstruction permanently revised the long held view that a facial prosthesis was a last resort for the patient and surgeon alike. Since that time, the use of extraoral osseointegration has expanded considerably. The present review of the literature considers indications and methods of care for aspects of ...

Introduction. Numerous devices have been introduced for correction of Class III malocclusion and maxillary deficiency. Aim. To assess the dentoskeletal effects of miniplates combined with Class III traction in treating Cl III malocclusion and maxillary deficiency in growing patients. Methods. This case describes the treatment of a maxillary-deficient 11-year-old boy by using miniplates. The pat...

This study aims to investigate the effects of shoe traction and obstacle height on lower extremity relative phase dynamics (analysis of intralimb coordination) during walking to better understand the mechanisms employed to avoid slippage following obstacle clearance. Ten participants walked at a self-selected pace during eight conditions: four obstacle heights (0%, 10%, 20%, and 40% of limb len...

PURPOSE To determine the topographic effects of zonular tension on the anterior surface of the human crystalline lens. METHODS Real-time topography of the anterior surface of seven fully relaxed, freshly extracted intact, clear, human crystalline lenses aged 3, 17, 45, 54, 54, 56, and 56 years was qualitatively obtained before, during, and after the application of zonular traction. Zonular tr...
