OBJECTIVES The marginal adaptation of full coverage restorations is adversely affected by the introduction of luting agents of various minimum film thicknesses during the cementation process. The increase in the marginal opening may have long-term detrimental effects on the health of both pulpal and periodontal tissues. The purpose of this study was to determine the effects of varying seating forces (2.5, 12.5, 25 N), venting, and cement types on post-cementation marginal elevation in cast… 
Effect of venting on the marginal seal of a complete cast crown
Introduction: A complete cast crown seated with good marginal and occlusal adaptation is very important for the health of the stomatognathic system. The cementation that prevents the complete crown
In vitro fatigue resistance of CAD/CAM composite resin and ceramic posterior occlusal veneers.
TLDR
Posterior occlusal veneers made of composite resin (Paradigm MZ100) had significantly higher fatigue resistance compared to IPS Empress CAD and IPS e.max CAD, and demonstrated survival rates of 30% and 100%, respectively.
Seating load parameters impact on dental ceramic reinforcement conferred by cementation with resin-cements.
TLDR
The magnitude of resin-reinforcement conferred was sensitive to the loading parameters investigated although the mechanisms underlying the variation appear complex.

TLDR
It was possible, by using venting, low forces and Ketac-cem Applicap, to achieve a low marginal discrepancy with low crown deformation, and Venting diminished the seating discrepancy to acceptable levels when higher forces were used with Phosphacap.
Risk of onlay fracture during pre-cementation functional occlusal tapping.
TLDR
To evaluate in vitro the pre-cementation resistance of CAD/CAM onlays subjected to functional occlusal tapping, an extracted tooth model with simulated bone and periodontal ligament was used to make a mesio-occlusal onlay preparation, showing the minimum risk compared to ceramic ones.
Influence of different luting agents on the marginal discrepancy of Procera Allceram alumina crown copings--an experimental study.
TLDR
It is concluded that different luting media have a definite effect over the final fit of AllCeram coping and Distal axial surface demonstrated a wider gap among all the luting agents.
Effect of crown lengthening and ferrule placement on static load failure of cemented cast post-cores and crowns.

TLDR
The combination of simulated surgical crown-lengthening and more apical crown margin placement to provide a 2-mm crown ferrule on a decoronated mandibular second premolar analog resulted in a reduction of static load failure for the restored analog tooth.
Influence of material selection on the risk of inlay fracture during pre-cementation functional occlusal tapping.
TLDR
To evaluate in vitro the pre-cementation resistance of CAD/CAM inlays subjected to functional occlusal tapping, an extracted tooth model with simulated bone and periodontal ligament was used to make a medium-size mesio-occlusal inlay preparation.
In vivo retrospective study of cement thickness under crowns.

TLDR
Under clinical conditions where more inherent difficulties exist, special measures must be taken to alleviate the consequences of cement fluid dynamics, implying that incomplete seating is strongly related to tilting or oblique seating.
Digital dynanometer for cementation and its influence on the film thickness of ceramic restorations.
The aim of this study was to develop a standardization technique of cementation force. Firstly, a digital dynamometer for clinical application was developed for standardization of the cementation

Relief of resistance of cement of full cast crowns
T HE RESISTANCE OF cementing materials is a factor that prevents cast restorations from being seated correctly. Such a failure in seating restorations, if slight, can be compensated by malleting or
Effect of venting on cast gold full crowns.
TLDR
This study underlines the difficulties involved in using an explorer and radiographs to evaluate a subgingival margin after cementation of a cast restoration and recommends a procedure that can be accomplished at the chair with a minimum of time and equipment to improve the marginal adaptation of full-crown castings.

TLDR
C capsulated zinc phosphate cement gave gradually increasing seating discrepancies with time, but providing 45 microns of space was present, the crown could be well seated up to 3 minutes after mixing, and it is argued that this cement is particularly suitable for cementing burnishable inlays.
The effect of venting on the strength of Dicor and Hi-Ceram ceramic crowns.
: Research has shown that external venting improves the marginal fit of cast crowns by decreasing hydrostatic pressure during seating. In turn, improving marginal fit has been shown to increase the
Reassessment of die-spacer with dynamic loading during cementation.
TLDR
This investigation reassessed paint-on die-spacer for its effect on completeness of seating and retention when dynamic seating was used and found crowns made from dies without spacer were significantly more retentive than those made from spaced dies.

TLDR
Methods for eliminating the effect of internal discrepancies which cause a rebound effect, requiring occlusal reduction and adjustment of faulty margins are described, and die spacing provided 25% better retention than when stress areas were not relieved.
Effects of cement, cement space, marginal design, seating aid materials, and seating force on crown cementation.
TLDR
The use of a die spacer, a heavier force of 30 lb, and glass ionomer cement significantly improved crown seating and the beveled preparation led to superior crown seating when the heavier force or glass ionomers cement was used.
Deformation of crowns during cementation.
TLDR
It is suggested that low viscosity cements, low seating forces, and die spacing be used to decrease the deformation of crowns during seating to explain several clinical phenomena.
An investigation of dental luting cement solubility as a function of the marginal gap.
TLDR
The purpose of this study was to investigate the rate of type I zinc phosphate cement solubility as it relates to the degree of marginal opening and the effects of convective forces on cement dissolution in a dynamic environment.
Improving the fit of crowns with die spacers.
TLDR
This investigation studied the dependence of seating crowns on the thickness of layers of spacers applied to dies and found that leaving the cervical part of the axial walls near the margin uncovered with spacer negates the effect of a thick spacer on the remaining die surface almost completely and is therefore contraindicated.
