A Comparison Study of Marginal and Internal Fit Assessment Methods for Fixed Dental Prostheses
Journal of Clinical Medicine, 2019 Numerous studies have previously evaluated the marginal and internal fit of fixed prostheses; however, few reports have performed an objective comparison of the various methods used for their assessment.

Considerations in measurement of marginal fit
The Journal of Prosthetic Dentistry, 1989The terminology describing "fit" and the techniques used for measuring fit vary considerably in the literature. Although fit can be most easily defined in terms of "misfit," there are many different locations between a tooth and a restoration where the measurements can be made.

Marginal fit of direct temporary crowns
The Journal of Prosthetic Dentistry, 1982This study compared the effect that shrinkage of four brands of temporary crown and fixed partial denture resins has on the marginal fit of crowns made from them. Under the conditions of this study, crowns made from Coldpac had marginal discrepancies approximately four times larger than those made from Scutan.

Marginal Fit of Electroformed Ceramometal Crowns
Journal of Prosthodontics, 1996PurposeA method of fabricating ceramometal crowns using gold copings produced by an electroforming process has been described, which purportedly results in restorations exhibiting an excellent marginal fit. This study compares the fit of electroformed ceramometal crowns with ceramometal crowns fabricated using conventional lost wax casting techniques ...

Marginal fit of castable ceramic crowns
The Journal of Prosthetic Dentistry, 1992The objective of this study was to measure marginal fit of castable ceramic versus gold crowns. Full veneer gold and ceramic crowns were made on Ivorine dies. Crowns were cemented, embedded, sectioned faciolingually and mesiodistally, and photographed for measurement of absolute marginal discrepancies (cavosurface angle to casting margin) to evaluate ...

Evaluation of the Marginal Fit of Implant-Supported Crowns
Journal of Long-Term Effects of Medical Implants, 2020Marginal 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

Gingival and alveolar bone reaction to marginal fit of subgingival crown margins
European Journal of Oral Sciences, 1986Abstract — 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, 1995The 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.

Cervical marginal fit of proximal amalgam restorations
Journal of Dentistry, 1994This study investigated the relationship between the adaptation, apical location and gap width of the cervical margin of proximal amalgam restorations. Three hundred and seventeen proximal cervical margins were studied in 243 extracted teeth. The restorations were categorized as 'flush fitting'; 'small overhang', or 'large overhang', based on ...

Radiographic assessment of the marginal fit of cast restorations
The Journal of Prosthetic Dentistry, 1984N umerous studies have demonstrated the effect of improperly fitting crown margins on plaque accumulation, gingival inflammation, and alveolar bone 10ss.‘-~ Renggli’O reviewed the literature on the influence of the marginal adaptation of dental restorations on the gingiva and gingivitis-promoting factors. It is obvious from all the experimental studies
