Gingival and alveolar bone reaction to marginal fit of subgingival crown margins

European Journal of Oral Sciences, 1986
Abstract — Interproximal subgingival marginal discrepancies of full coverage restorations were compared with adjacent crevicular fluid flow and percentage radiographic periodontal bone loss. A total of 88 patients with 116 premolar crowns were evaluated.

MARGINAL ADAPTABILITY AND FIT OF CERAMIC MILLED INLAYS

The Journal of the American Dental Association, 1995
The authors investigated the marginal adaptation and internal fit of ceramic inlay made by a ceramic milling system. The study's results indicated that the mean marginal and internal gap size of the ceramic inlay restorations was less than 100 microns, making the fit clinically acceptable.

Margin fit of metal crowns and bridge retainers

Acta Odontologica Scandinavica, 1985
The margin fit of metal crowns and bridge retainers was examined radiographically in individuals who were registered to receive treatment at the School of Dentistry, University of Bergen. One sample consisted of 184 individuals registered in 1967-68 and another one of 232 individuals registered in 1982-83.

Marginal Fit of Implant-supported All-Ceramic Zirconia Frameworks

Journal of Oral Implantology, 2012
This study evaluated the effect of fabrication techniques and cyclic loading on the vertical marginal fit of implant-supported fixed partial denture (FPD) frameworks. Thirty implant-supported 3-unit FPD frameworks were fabricated on a model system, divided into 3 equal groups (n = 10).

Evaluation of the Marginal Fit of Implant-Supported Crowns

Journal of Long-Term Effects of Medical Implants, 2020
Marginal adaptation is an important feature of implant-supported crowns, ensuring long-term survival and the success of the prosthetic restoration. The long-term success of a fixed prosthesis such as an implant is highly associated with its marginal adaptation. Improper marginal adaptation increases the risk of plaque accumulation, which leads to decay

Functional marginality and response-surface fitting

Journal of Applied Statistics, 2000
Well-formed polynomials contain the marginal terms of all terms; for example, they contain both x 1 and x 2 if x 1 x 2 is present. Such models have a goodness of fit that is invariant to linear transformations of the x variables. Recently, selection procedures have been proposed which may not give well-formed polynomials.

Surface smoothness and marginal fit with phosphate-bonded investments

The Journal of Prosthetic Dentistry, 1979
Two phosphate-bonded investments and one calcium sulfate investment were evaluated for the surface smoothness and marginal fit they impart to gold castings. A modified technique was also evaluated for each phosphate-bonded investment, where the silica sol was not diluted and the spatulation time was reduced.

Comparison of Marginal Fit between All‐Porcelain Margin versus Alumina‐Supported Margin on Procera^® Alumina Crowns

Journal of Prosthodontics, 2009
Abstract Purpose: Procera® Alumina crowns are widely used; however, the effect of crown margin design on marginal fit is unknown. This study measured and compared the precision of fit of Procera® Alumina crowns with two crown margin designs: all‐porcelain versus alumina‐supported margins.

[Studies on marginal fit of Dicor crowns].

Deutsche zahnarztliche Zeitschrift, 1990
Dicor crowns may present marginal defects, among other reasons because they require preparation of a circular ledge with rounded internal line angles. In studying this problem, 21 teeth that could no longer be saved were prepared in vivo and provided with Dicor crowns in our hospital.

Marginal fit of titanium metal-ceramic crowns.

The International journal of prosthodontics, 2005
This study aimed to compare the marginal fit of 2 kinds of metal-ceramic crowns-crowns cast from commercially pure titanium and Procera titanium crowns.Ten copings of each type were prepared, veneered with low-fusing porcelain, and bonded with glass-ionomer cement.
