A dynamic smile is desirable at all age groups and orthodontists are smile architects. To construct a beautiful smile the various macro esthetic and micro esthetic factors must be kept in mind. Frontal esthetics is very crucial and poor frontal esthetics can be very bothering for the patient. In this article we are presenting a case report on how a simple removable appliance addressed the chief...

For a k-connected graph or matroid M , where k is a fixed positive integer, we say that a subset X of E(M) is k-removable provided M\X is k-connected. In this paper, we obtain a sharp condition on the size of a 3connected binary matroid to have a 3-removable circuit.

This article reviews the literature on planning the support of bounded saddles of removable partial dentures or fixed bridges. Three-dimensional photoelastic analysis was used to examine stresses on removable partial dentures of different designs, and possible model structure changes raised for further investigation.

The Traveling Salesman Problem (TSP) is a classical problem in discrete optimization. Its paradigmatic character makes it one of the most studied in computer science and operations research and one for which an impressive amount of algorithms (in particular heuristics and approximation algorithms) have been proposed. While in the general case the problem is known not to allow any constant ratio...

the aim of this study was to compare the ability of 46 isolates of candida albicans to produce mycelial form with oral source in three groups of individuals including, removable appliance wearers, non-wearers and oral medicine patients. saliva samples were obtained from all subjects along with a foam imprint from the fitting surface of the upper removable appliance in the case of patients. colo...

Removable partial dentures are still widely used to repair dental defects. Due the problems of aesthetic defects, heavy weight, and metallic odor metal removable that in clinical practice, non-metallic alternative materials now actively explored. As a new material with good physical chemical properties, polyether ether ketone (PEEK) has been tried be fabrication dentures. In this paper, we revi...

in present study a digital model of hemimaxillectomy was reconstructed by computer and stress distribution of removable partial dentures in tissues, periodontal ligament and bone were thoroughly evaluated. the maximum stress of two different removable partial denture designs which contained buccal and lingual c-shaped clasps respectively were analyzed and compared. it was assumed that a 90 gram...

We give an example of a totally disconnected set E ⊂ R which is not removable for quasiconformal homeomorphisms, i.e., there is a homeomorphism f of R to itself which is quasiconformal off E, but not quasiconformal on all of R. The set E may be taken with Hausdorff dimension 2. The construction also gives a non-removable set for locally biLipschitz homeomorphisms. 1. Statement of results If a h...
