The purpose of this study were to compare the emergence profiles of crowns with their contralateral tooth, in vitro, and to determine if there is any association between the design of tooth preparations and the resultant emergence profile. 50 working models used for single crown construction were examined. Measurements of the faciolingual width of the crowns and contralateral teeth were taken u...

An ideal emergence profile is vital for maintaining gingival health and developing esthetics. The ovate pontic which mimics a natural tooth gives the most appropriate emergence profile. For a successful ovate pontic restoration, an alveolar ridge of sufficient height and width is necessary to enhance the deficient ridge and to achieve an esthetic emergence profile. Interpositional graft was car...

We propose a multilayered semantic social network model that offers different views of common interests underlying a community of people. The applicability of the proposed model to a collaborative filtering system is empirically studied. Starting from a number of ontology-based user profiles and taking into account their common preferences, we automatically cluster the domain concept space. Wit...

The paper presents a generic framework for designing and implementing multiuser virtual exhibitions that adapt visitors’ preferences and goals and foster the emergence of communities with common interests. A user-oriented platform for designing and executing virtual exhibitions has been presented in which implicit generation and adjustment of user profile allows exhibition to dynamically adapt ...

The emergence of social tagging systems enables users to organize and share their interested resources. In order to ease the humancomputer interaction with such systems, extensive researches have been done on how to recommend personalized tags for rescources. These researches mainly consider user profile, resource content, or the graph structure of users, resources and tags. Users’ preferences ...
