In this study compared single stopping rules models to the Cast-Net stopping rule model. The Cast-Net model assumes that several stopping rules can be used simultaneously to determine the stopping point to stop information search and to proceed to making a final decision. We analyzed whether the Cast-net model would pay the price for being more complex when compare to single stopping rule model...

coronal tooth tissue can use a post to retain a core enabling definitive restoration. Post material has been, until recently, primarily metal--be it cast or prefabricated. Currently, fiber-posts are promoted as being advantageous due to a favorable failure mechanism which may protect the root from fracture [1]. Endodontic posts are necessary to provide adequate retention and support when no suf...

STATEMENT OF PROBLEM Little peer-reviewed information is available regarding the accuracy and reproducibility of digitally fabricated casts compared to conventional nondigital methods. PURPOSE The purpose of this in vitro study was to compare the accuracy and reproducibility of a digital impression and cast fabrication with a conventional impression and cast fabrication. MATERIAL AND METHOD...

INTRODUCTION An accurate and passive fit of implant framework prosthesis, as well as the successful surgical operation is suggested as one of the critical requirements for long-term implant success. OBJECTIVE The purpose of this in vitro study was to evaluate the accuracy of the master cast using open tray impression technique with conventional and novel splinting materials. METHODOLOGY A m...

In this paper, we propose a novel image enhancement algorithm via anti-degraded model and L1L2-based variational retinex (AD-L1L2VR) for non-uniform illumination endoscopic images. Firstly, a haze-free endoscopic image is obtained by an anti-degraded model named dark channel prior (DCP). For getting a more accurate transmission map, it is refined by using a guided image filtering. Secondly, the...

AIM The aim of this study was to determine the wettability of different hydrophilic and hydrophobic elastomeric impression materials and the gypsum castability. MATERIALS AND METHODS The wettability was evaluated by determining the contact angles of different elastomeric impression materials. The contact angle was determined by placing a drop of aqueous solution of calcium sulfate dihydrate o...

QDT 2004 uccessful osseointegration and function have traditionally been the main goals of implant therapy. However, successful osseointegration does not automatically lead to an optimal esthetic result, and inadequate treatment planning may severely compromise the esthetic result regardless of biologic and functional integration. Exact replication of the natural dentition, maintenance of a har...
