Special Issue Information

Dear Colleagues,

Restorative dentistry has seen remarkable progress in recent years, mainly due to its implementation into the daily clinical practice of digital workflows and novel dental materials. The continuous improvement of modern manufacturing technologies such as CAD/CAM and 3D printing requires the constant development of highly specialized dental materials with improved characteristics and properties.

This Special Issue aims to focus on the latest advancements in the dental biomaterials used in restorative dentistry, considering their composition; biological, mechanical, and optical properties; and the latest manufacturing technologies used for their processing.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

Digital dentistry;
Composite and ceramic restorations;
Esthetic dentistry;
Prosthodontics;
Implantology.

We look forward to receiving your contributions.

Abstract

This study seeks to understand the effects of new hydrogels based on Oregano^® essential oil, Frankincense^® essential oil, and the Thieves^® blend, which includes clove, lemon, cinnamon bark, eucalyptus radiata, rosemary extract, and Frankincense^® essential oil through in vitro cytotoxicity and antimicrobial analysis. Mesenchymal stem cells (D1MSCs) generated from the dental papilla of human wisdom teeth germs were used to test the hydrogels’ cytotoxicity (D1MSCs). The chemical makeup of the tested essential oils (EO) was determined using GC-MS analysis, and their presence in the novel hydrogels was determined using UV-VIS analysis. The primary constituents of the essential oils identified as being present were eugenol, pinene, limonene, carvacrol, and cymene. The primary constituents from essential oils identified by the absorption spectra included eugenol, pinene, limonene, carvacrol, and cymene. The presence of essential oils in the hydrogel composition was also clearly discernible. All of the studied compounds had a reduced cytotoxic effect on cell cultures, proving the lack of in vitro toxicity of the gels. This study demonstrates that hydrogels enriched with pure natural extracts of essential oils have a tangible in vitro antimicrobial potential, especially for Staphylococcus aureus and Bacillus cereus.

Effect of White Light-Emitting Diode Illuminants Recommended by the CIE on Colors of Dental Ceramic Materials

Abstract

The aim of this study was to evaluate color inconstancy of dental ceramics under the white light-emitting diode illuminants recently proposed by the CIE. From spectral reflectance factors of 18 dental ceramics (VST, NSP, and IEC; shades A1, A2, A3, A3.5, B2, and C2), the corresponding colors under illuminant D65 and CIE 1931 Standard Colorimetric Observer were computed for all samples, using the chromatic adaptation transform CIECAT16. CIEDE2000 color differences between dental ceramics illuminated by CIE D65 standard illuminant and different white LED illuminants were calculated. Perceptibility and acceptability thresholds (PT₀₀ and AP₀₀) in dental ceramics were used to analyze color changes. Color gamut size was within the same range for all illuminants and for all ceramics, since MCDM computed values were 4.1–4.4 for VST, 4.0–4.2 for NSP, and 4.3–4.6 for IEC. For all ceramics and shades, the color inconstancies were higher than 50:50% PT₀₀ and, in general, lower than 50:50% AT₀₀. The effect of CIE-proposed LED illuminants on dental ceramic is perceptible and slightly lower than on natural teeth. Dental clinicians should consider these lighting effects on the visual appearance of dental ceramics. Full article

Abstract

A well-made provisional fixed prosthesis must present as a preview of the future prosthesis and may also augment the health of the abutments and periodontium. Provisional restorations have been prepared chairside with polymethyl methacrylate (PMMA) since time immemorial. CAD/CAM additive and subtractive technologies have revolutionized the fabrication of interim restorations in dental clinics. The current literature lacks substantial data about retention of provisional crowns manufactured using Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) additive and subtractive techniques with various temporary cements. This in vitro study aims to assess and compare the retention of temporary/provisional anterior crowns based on the combined effect of different digital manufacturing techniques, preparation tapers, and the temporary cements used for cementation. Two maxillary right central incisor typodont teeth were prepared to receive all-ceramic crowns, one with a 10-degree taper and the other with a 20-degree taper. Forty 3D-printed working models with the 10° taper and forty working models with the 20° taper were prepared to receive the temporary crowns. Forty temporary crowns were 3D-printed and forty crowns were milled (20 from each taper group). Kerr Temp-Bond NE conventional cement and Kerr Temp-Bond clear cement were used for cementation in the two groups. The number of samples per test group was 10. All samples were thermocycled and subjected to a universal testing machine to measure the pull-off force until retention loss (N) under tension with a crosshead speed of 5 mm/min. The pull-off force was highest for group 8, i.e., 3D-printed crowns with a 20° taper and cemented with Kerr Temp-Bond clear cement, followed by groups 6, 7, 4, 5, 3, and 2. Group 1, i.e., milled crowns with 10° taper cemented with Kerr Temp-Bond NE conventional cement, exhibited the lowest pull-off retentive force. The clinical selection of long-term provisional crowns fabricated using 3D-printing technology, prepared with 10° or 20° tapers, and cemented with clear cement, is the most favorable in terms of the retention of provisional crowns. 3D-printed provisional crowns can be used as an alternative to conventional and CAD/CAM-milled crowns for long-term provisionalization.

Magnetic Mallet and Laser for a Minimally Invasive Implantology: A Full Arch Case Report

by Gianluigi Caccianiga, Lorenzo Ferri, Marco Baldoni, Ayt Alla Bader and Paolo Caccianiga

Abstract

In the past, complex rehabilitations, such as the rehabilitation of an entire arch with a prosthesis on implants, were reserved for the few patients who presented an optimal state of health as the interventions were long and traumatic. Nowadays, the use of devices such as the Magnetic Mallet and the laser allows us to perform the same interventions in less time and in a minimally invasive way. The case report we present shows how a fragile patient, subjected to the insertion of eight implants on the same day, had a positive response, thanks to the use of a Magnetic Mallet to prepare the implant sites, the application of the photodynamic therapy without dye (diode laser + hydrogen peroxide) to decontaminate the post-extraction alveoli and the use of an erbium laser to induce more bone bleeding and promote healing. The implants were then loaded in 48 h with a Toronto-type temporary total prosthesis. The patient had a pain-free and complication-free outcome. It is interesting to note how technological development, aimed at reducing the morbidity of surgery, makes it possible to perform almost all surgical therapies, even the most advanced, on any patient, regardless of general health conditions.
