Journal of Dentistry, 1993
A critical review of studies assessing the marginal adaptation of direct placement, plastic restorations is presented. The effects upon adaptation of cavity design and location of cavity margins are examined, together with the effects of differing placement and finishing techniques.

Marginal adaptation of composite resins
Journal of Oral Rehabilitation, 1975SummaryThe historical development and important properties of composite resins are briefly reviewed. Experimental work has been undertaken to examine the marginal adaptation of three commercially available composite resins in 100 Class II and Class V restorations; dye penetration tests were used and the measurement of the gap at the tooth/ restoration ...

The effect of margin design on the marginal adaptation of temporary crowns
Journal of Oral Rehabilitation, 1994SummaryAccurate marginal fit and proper contour and surface finish of a temporary crown are needed to maintain healthy contiguous gingiva before the placing of the final restorations.In this study, the effect of two finish line types and the period of their remaining in the mouth on the marginal adaptation of temporary crowns was examined.According to ...

Adaptation of silicate and Adaptic to the margins of cavities
Journal of Oral Rehabilitation, 1975SummaryThe effects of etching of the enamel, on the adaptation of silicate and Adaptic to the cavity walls was examined with the scanning electron microscope. Replica methods were utilized to ensure that no shrinkage of the filling materials was caused by the vacuum in the instrument.

Marginal adaptation of castable ceramic crowns
The Journal of Prosthetic Dentistry, 1991Tooth preparations and seating techniques of castable ceramic crowns differ from metal ceramic crowns. This study evaluated the variable effects of cementation on the marginal adaptation of Dicor, Cerestore, and porcelain-fused-to-metal crowns. The shoulder preparation was maintained for ceramic crowns, and a cavosurface bevel was designed for metal ...

Gain Margins of Adaptive Control Systems
IEEE Transactions on Automatic Control, 2010This paper presents a systematic study of the gain margins (GM) of adaptive control systems: the specification of the parameter range of a control gain matrix in a designed adaptive control system for maintaining the desired closed-loop signal boundedness and asymptotic tracking performance.

Marginal adaptation of glass-ionomer cements
The Journal of Prosthetic Dentistry, 1983The effect of thermocycling on the marginal adaptation of two glass-ionomer cements was determined by means of scanning electron microscopy. Small gaps in the cement as well as at the enamel-cement interface were observed after curing, but these phenomena were not enhanced by thermocycling.

Pseudo-margin-based universal domain adaptation
Knowledge-Based Systems, 2021Abstract As a more practical setting for unsupervised domain adaptation, Universal Domain Adaptation (UDA) is recently introduced, where the structure of the target label set is assumed to be unavailable. One of the significant challenges in UDA is identifying the common label set shared by source and target domains without labels in the target ...

Marginal adaptation of porcelain margins in metal ceramic restorations.
The International journal of prosthodontics, 1992The 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.
