Flexible partial denture- material science and a case report

Abstract

Partially edentulous patients need treatment to restore missing teeth and surrounding structures. Partial dentures are mode of treatment for replacing some of the missing teeth in either arch. Partial dentures are made of variety of materials. Some are made of only acrylic material and some are metal framework with acrylic extensions to replace missing teeth. Recently flexible materials are in use to fabricate tooth supported prosthesis. These materials has advantage over conventional metal and acrylic dentures as there is no metal clasp around the tooth, they are more retentive giving life like prosthesis and are translucent by which they match the color of underlying mucosa.It is seen that patient acceptance is more for flexible partial dentures as they are less likely to cause mucosal irritation and pain.

ASL Detection and Gesture Based Control of Robotic Hand Using Image Processing

“…Ashish Sharma [4] discusses a method where the model was made by utilizing techniques including canny edge detection, bag of world and ORB. The proposed technique has been tested against many different pre-processing techniques including Histogram of Gradient, PCA(Principal Component Analysis) and LBP( Local Binary Pattern) were then passed through various classifiers including SVM(Support Vector Machine), Random Forest, Multi-Layer Perceptron and so on.…”

“…Here in this project, a camera module is used to capture the live data in the form of hand gestures and then process it using Computer Vision (OpenCV). The static hand gestures, basically the alphanumericals in the standard ASL dataset are then trained with the help of Machine Learning Algorithms [4]. The user enacts each symbol of the word they are trying to communicate, and the output letters will be displayed in real time on the screen [5].…”
