“…The patients that did not fulfill the eligibility criteria, were excluded due to insufficient bone volume at implant sites and jaw shape. Bone volume has a substantial impact on available prosthetic options and should be a consideration in all treatment plans [23]. Our analysis showed that bone volume was a critical factor, leading more men than women to be eligible for this treatment concept.…”

The aim of the study was to evaluate the proportion of patients recommended for full-arch mandibular restoration that would be eligible for treatment with a recently developed premanufactured full-arch prosthesis (Trefoil™, Nobel Biocare) based on the morphology of their lower jaw. Anonymized cone beam computed tomography (CBCT) data from 100 partially and fully edentulous patients referred for full-arch mandibular restoration were retrospectively collected from an imaging center database. Using custom-built software, CBCTs of mandibles were registered to a reference CBCT of a patient treated previously with a premanufactured full-arch prosthesis to determine if patients had adequate horizontal width and vertical height for implant placement. Bone height and thickness around simulated implants and distances to the incisive canal were evaluated. Mandibular arch width and semi-automated volume calculations were also performed. Using the system-specific 5.0 mm diameter implants with lengths of 13 and 11.5 mm, 85% and 86% of patients, respectively, were eligible for treatment with the standardized prosthesis. Eligibility was higher for men than women (odds ratio = 3.9, p = 0.045) due to increased bone volume. Based on mandibular morphology, our results suggest that the standardized treatment concept could serve a large percentage of patients with edentulous mandibles or failing dentition in the mandible.

“…Therapy with cold physical plasmas shows beneficial effects in dermatology, [33,34] especially in wound healing. [10,35] With emergence of novel therapeutic applications and plasma source concepts, [36][37][38] there is an increasing need not only to show treatment efficacy but also to assess toxicological aspects. In this study, we aimed at investigating the suitability of zebrafish larvae as a toxicological model in plasma medicine.…”

Plasma technology has emerged as a promising tool in medicine that, however, requires not only efficacy but also toxicological assessments. Traditional cell culture systems are fast and economical, but they lack in vivo relevance; however, rodent models are highly complex and necessitate extended facilities. Zebrafish larvae bridge this gap, and many larvae can be analyzed in well plates in a single run, giving results in 1–2 days. Using the kINPen, we found plasma exposure to reduce hedging rates and viability in a dose‐dependent manner, accompanied with an increase in reactive oxygen species and a decrease of glutathione in plasma‐treated fish. Modest growth alterations were also observed. Altogether, zebrafish larvae constitute a fast, reliable, and relevant model for testing the toxicity of plasma sources.

“…8,9 Other authors recom mend the use of acrylic resin teeth for the fullarch prosthe ses restored over implants, since this type of material would compensate for the lack of resilience of this rehabilitation system, which is different from natural teeth, as natural teeth have periodontal ligaments. 10,11 In a finite element analysis study evaluating stress distri bution in the supporting structures with regard to materials of different hardness, the researchers showed that both resin types (composite and ceramicfilled resin) transmitted less load than porcelain or the gold alloy. 10 Other finite element analysis studies were unable to demonstrate benefits in stress distribution in the supporting structures with the use of more resilient materials.…”

Background. Various ceramic materials have been used for esthetic rehabilitation with implants, but the issues regarding the dissipation of masticatory loads are not well understood.Objectives. This in vitro quasi-static study aimed to evaluate with the photoelasticity test the dissipation of stress around dental implants with regard to different rehabilitation materials. Material and methods.A photoelastic model was elaborated in resin, where a conical Morse-tapered implant was inserted. On the abutments (1 per crown), 6 single crowns were prepared using different materials to form 6 groups: feldspathic ceramic (G1); chrome-cobalt alloy covered with ceramic (G2); hybrid ceramic (G3); zirconia covered with ceramic (G4); zirconia (G5); and lithium disilicate (G6). Axial loads of 100 N (load 1) and 300 N (load 2) were applied in the center of the crowns, and photoelastic images were captured and analyzed. The total area of stress dissipation was measured for each group. Then, a computational program was developed to measure the number of pixels of the colors generated in each group. Two image sizes were analyzed -total image and crestal image. Results.Counting the numbers of pixels of the colors in the total images showed that G6 > G4 > G5 > G1 > G2 > G3 when load 1 was applied. When load 2 was applied, the sequence was G6 > G4 > G1 > G3 > G2 > G5. In the evaluation of the crestal area, the obtained results were G4 > G5 > G1 > G3 > G2 > G6 with load 1 and G5 > G1 > G2 > G6 > G4 > G3 with load 2. Conclusions.Within the limitations of this in vitro quasi-static study, the findings indicate that the zirconia crown (G5) presented higher stress in the crestal images, while the lithium disilicate crown (G6) presented higher stress in the total images.
