The aim of this study was to evaluate changes in the facial profile resulting from the use of a twin block (TB) functional appliance. The sample comprised 38 patients (24 males and 14 females) with a Class II division 1 malocclusion. Nineteen subjects were treated with a functional appliance while the remaining 19, who did not undergo any intervention, served as the control. The mean age of the...

INTRODUCTION Craniofacial growth of the skeleton and soft tissue influences the final configuration of occlusion and overall facial esthetics. MATERIALS AND METHODS Two hundred samples were taken from Himachali ethnic population with age ranging from 18 to 28 years. The records will then be scaled to life size and landmarks will be located on the digitized image to obtain all linear and angul...

The defects of the alveolar ridge can result from various causes, most common being the collapse of alveolar bone during extraction. Localized defects of alveolar crest impair prosthetic rehabilitation due to poor emergence profile of function. Several alternatives have been proposed to restore the damaged ridge by hard and soft tissue augmentation. Various soft tissue ridge augmentation techni...

Introduction Rehabilitation of the edentulous alveolar ridge with dental implants is a common treatment modality. Successful esthetic and functional implant rehabilitation relies on sufficient bone volume in the vertical and horizontal dimensions, adequate bone contours, ideal implant positioning and angulation, periodontally healthy peri-implant soft tissue, adequate soft tissue contours, and ...

a pseudo aneurysm results from leakage of blood from an artery after trauma or dehiscence or separation of a surgical anastomosis. the reported rate of pseudo aneurysm in access sites range from 0.88% to 8%. it has some cause like penetrating trauma, blunt trauma and endovascular procedure. the differential diagnoses of this lesion are hematoma, av fistula, lymphadenopathy, lymphocele, dvt, com...

a case of soft tissue defect of dorsal hand due to crush injury in a 37-year-old female is reported here. the reconstructive surgery was performed for the hand soft-tissue defect. among different flaps used in the surgery, the regional flap such as radial forearm flap can be done. but usually it is not accepted by patient because of cosmetic appearance. therefore, random pattern abdominal flap ...

nowadays, one of the main problems encountered in minimally invasive surgery and telesurgery is the detection of arteries in tissue. in this study, for the first time, tactile detection of an artery in tissue and distinguishing it from the tumor has been modeled by finite element method. in this modeling, three 2d models of tissue have been created: tissue, tissue including a tumor, and tissue ...

normal 0 false false false en-us x-none ar-sa background: robotic needle insertion in biological tissues has been known as one the most applicable procedures in sampling, robotic injection and different medical therapies and operations. objective: in this paper, we would like to investigate the effects of angular velocity in soft tissue insertion procedure by considering force-displacement diag...

conclusion our preliminary results have shown that although there is some overlap between benign and malignant tumors, adding dwi, mr imaging to routine soft tissue tumor protocols may improve diagnostic accuracy. results there was only one patient with a malignant cystic tumor and was not included in the statistical analysis. the median adc values of benign and malignant tumors were 2.31 ± 1.2...

in this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. the polymers were characterized by nuclear magnetic resonance (nmr) spectrometry, fourier transform infrared spectroscopy (f...
