Marginal adaptation of porcelain margins in metal ceramic restorations.

The International journal of prosthodontics, 1992
The purpose of this study was to evaluate the marginal adaptation of all-porcelain labial margin metal ceramic crowns using a porcelain shoulder material containing a light-polymerizing resin and one that used a direct-lift technique. Conventional metal margin restorations served as controls.

Marginal adaptation of nine commercial intermediate resins

Dental Materials, 1991
The bonding efficacy of nine commercially available intermediate resins was examined by measuring the maximum contraction gap of a light-activated composite in a cylindrical cavity of human dentin. With only one exception, the marginal adaptation of the composite improved significantly when the intermediate resins were combined with an experimental ...

Adaptive jitter margin PID controller

2008 IEEE International Conference on Automation Science and Engineering, 2008
This paper develops an adaptive controller for (wireless) networked control systems by combining delay estimation and a jitter margin based PID controller tuning. A control system with wireless measurement is assumed, where the network induces delay jitter.

Influence of preparation designs on marginal adaptation and failure load of full-coverage occlusal veneers after thermomechanical aging simulation.

Journal of Esthetic and Restorative Dentistry, 2019
OBJECTIVES To evaluate the fracture resistance and marginal quality of maxillary molars restored using lithium disilicate glass-ceramic (LDG) occlusal veneers with two preparation designs. METHODS Sixteen extracted maxillary molars were assigned to two

Marginalized Augmented Few-Shot Domain Adaptation

IEEE Transactions on Neural Networks and Learning Systems
Domain adaptation (DA) has recently drawn a lot of attention, as it facilitates unlabeled target learning by borrowing knowledge from an external source domain. Most existing DA solutions seek to align feature representations between the labeled source and unlabeled target data.
