Scanning Electron Microscopy

Scanning Electron Microscopy

A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Background:

Marginal fit is critical for the longevity and clinical success of dental restorations.
Computer-Aided DesignComputer-Aided Manufacturing (CAD/CAM) offers advanced solutions for fabricating dental prosthetics.
Evaluating the marginal integrity of different CAD/CAM materials is essential for clinical decision-making.

Purpose of the Study:

To compare the vertical marginal gap (VMG) of three chairside CAD/CAM inlay materials: VITA Enamic, CEREC Tessera, and Celtra Duo.
To assess the marginal fit using a standardized digital workflow and scanning electron microscopy (SEM).
To determine if material type significantly influences the marginal gap in CAD/CAM restorations.

Main Methods:

Standardized Class I inlay preparations were made in human molars.
Restorations were fabricated using a complete chairside CAD/CAM workflow, including intraoral scanning, design, and milling.
Vertical marginal gap (VMG) was quantified using SEM analysis at multiple sites per tooth.

Main Results:

Celtra Duo exhibited the lowest mean VMG (8.09 ± 1.98 µm).
VITA Enamic (27.90 ± 29.76 µm) and CEREC Tessera (32.72 ± 21.80 µm) showed higher mean VMGs with wider distributions.
A statistically significant overall effect of material on VMG was observed (p=0.040), though pairwise comparisons were inconclusive.

Conclusions:

An overall material effect on marginal fit was detected among the evaluated chairside CAD/CAM materials.
Celtra Duo demonstrated a trend towards superior marginal adaptation compared to VITA Enamic and CEREC Tessera.
All tested materials exhibited mean VMGs within acceptable clinical ranges, despite variations in fit.
