Marginal gap width of a new refractory porcelain system
The Journal of Prosthetic Dentistry, 1993This study was conducted to determine whether matching the physical properties of refractory die material to porcelain could increase the marginal accuracy of porcelain inlays. Restorations made with a matched Fortune refractory porcelain system were compared with restorations made with unmatched Vita porcelain and Polyvest refractory material.

Preliminary Evidence That Bioactive Cements Occlude Artificial Marginal Gaps
Journal of Esthetic and Restorative Dentistry, 2015AbstractPurposeThe objective of this preliminary laboratory study was to explore whether bioactive dental cements have the ability to seal marginal gaps as compared with other classes of dental cements.Materials and MethodsTooth discs (dentin/enamel) were positioned adjacent to a second disc of one of five possible dental cements (two bioactive and ...

Clinical marginal and internal gaps of Procera AllCeram crowns
Journal of Oral Rehabilitation, 2005summary This study evaluated the marginal and internal gaps of Procera AllCeram crowns in vivo using silicone materials. Ninety Procera AllCeram crowns were evaluated before final cementation. White and black silicone materials were used to record the marginal and internal fit; then the crowns were sectioned bucco‐lingually and mesio‐distally to ...

With the challenges of keeping testing costs down, DFT-based testing methods have been pursued [6–9, 47, 48]. The timing margining test is one of the widely adopted DFT methods by companies [8, 9]. Usually facilitated by a loopback on-die or off-die, the idea is to assess the margin in a given I/O’s timing and make the pass/fail decision.

Gap-tolerant half-disk bubble device margins
IEEE Transactions on Magnetics, 1978A simple model is presented which allows accurate prediction of bias margins of gap-tolerant half-disk propagation tracks for bubble domains. After this is verified by comparison with experimental margin data, an "isomargin" plot is derived to show how the margin varies as a function of W and G , where W is the minimum linewidth and G is the inter-bar ...

Efficacy of composite surface sealers in sealing cavosurface marginal gaps
Journal of Dentistry, 2006The ability of commercially available composite surface sealers to penetrate and seal a controlled gap formed in all-enamel margin, Class V in vitro resin composite restorations in human bicuspids was examined.A fluorescent red dye (Rhodamine B) was incorporated to a variety of commercially available composite surface sealers.

The effect of smear layer removal on marginal contraction gaps
Journal of Oral Rehabilitation, 1994SummaryThe presence of the smear layer prevents direct contact between dentine and a dentine adhesive. The use of agents to remove the smear layer theoretically should improve the bonding of composite resins to dentine. This study examined the effect of smear layer removal on the effectiveness of a dentine bonding agent in reducing marginal contraction

Marginal regression of gaps between recurrent events.
Lifetime data analysis, 2003Recurrent event data typically exhibit the phenomenon of intra-individual correlation, owing to not only observed covariates but also random effects. In many applications, the population may be reasonably postulated as a heterogeneous mixture of individual renewal processes, and the inference of interest is the effect of individual-level covariates. In

Purpose: Marginal integrity is a very important element in evaluating a restoration; however, there is no agreement in definition of a clinically acceptable margin. The purpose of this investigation was to examine margin acceptability using an explorer versus the actual marginal gap widths at four locations on uncemented crowns on three ...

Marginal leakage and marginal gap dimensions of three dentinal bonding systems.
American journal of dentistry, 1991Standardized cylindrical Class V preparations, 3 mm in diameter and 1.5 mm deep, were made on the roots of 60 extracted human maxillary permanent canines. The teeth were restored with Scotchbond 2/Silux (S); Gluma/Lumifor (G); and Tenure/Perfection (T), respectively.
