Evaluation of mandibular implant-supported fixed prosthesis retained by 3 dental implants, 1 straight and 2 angled: A retrospective clinical study.

Statement Of Problem: The minimum number of implants to support fixed complete dentures is still unclear.

Purpose: The purpose of this retrospective clinical study was to evaluate the survival rate of fixed complete dentures supported by 3 immediately loaded implants opposing maxillary complete dentures.

Material And Methods: A retrospective study of edentulous patients rehabilitated with complete dentures opposing mandibular metal-resin implant-supported fixed complete dentures supported by 3 immediately loaded implants was conducted in a 48-hour protocol.

Evaluation of Deep Eutectic Systems as an Alternative to Solvents in Painting Conservation.

Natural deep eutectic solvents (NADESs) are considered as green solvents, and due to their promising sustainability, they have been applied in many research fields. In this study, the main goal is to use various NADES systems to replace the traditional solvents used in conservation and restoration to remove varnish layers in a painting. The toxicity of traditional solvents, such as toluene or acetone, is well known in the chemistry field.

Fully Untethered Battery-free Biomonitoring Electronic Tattoo with Wireless Energy Harvesting.

Bioelectronics stickers that interface the human epidermis and collect electrophysiological data will constitute important tools in the future of healthcare. Rapid progress is enabled by novel fabrication methods for adhesive electronics patches that are soft, stretchable and conform to the human skin. Yet, the ultimate functionality of such systems still depends on rigid components such as silicon chips and the largest rigid component on these systems is usually the battery.

Does the natural maxillary dentition influence the survival rate of mandibular metal-resin implant-supported fixed complete dentures? A systematic review and meta-analysis.

Statement Of Problem: Consensus is lacking regarding the influence of the maxillary dentition on the survival rate of a mandibular metal-resin implant-supported fixed complete denture (MRISFCD) with distal cantilevers.

Purpose: The purpose of this systematic review was to identify whether an opposing natural dentition influences the survival rate of mandibular MRISFCDs.

Material And Methods: A literature search was performed up to February 2018 from MEDLINE/PubMed, Scopus, Web of Science, Cochrane Library, BBO/LILACS databases and also in the non-peer-reviewed literature through Open Grey.

Nutrition and Cancercapsaicin Treatment Reduces Tumor Growth, Tumor Cell Proliferation Ex Vivo and Partially Reverses Cancer Cachexia in Walker 256 Tumor-Bearing Rats.

Unlabelled: Capsaicin (trans-8-methyl-n-vanillyl-6-nonenamide) is the main pungent component found in hot peppers.

Aim: In this study, we investigated the effect of capsaicin treatment on tumor growth and the metabolic indicators of cachexia in Walker 256 tumor-bearing rats.

Methods: Male Wistar rats were inoculated subcutaneously in the right flank with 1 ml of a sterile suspension of 3 × 10 Walker tumor cells.

Is there enough evidence that mouthguards do not affect athletic performance? A systematic literature review.

Background: Although there is evidence that mouthguards prevent orofacial trauma occurrence during sport practice, the influence of this device on athletic performance has not been systematically quantified.

Objectives: We aim to systematically review the literature to determine the effect of mouthguards on athletic performance and if the type of mouthguard influences this overcome.

Materials And Methods: A comprehensive search was performed in the Systematic Electronic Databases: Pubmed, Scopus, Web of Science and the Cochrane Library from their inception to February 2017.

Prosthetic rehabilitation in a pediatric patient with hypohidrotic ectodermal dysplasia: a case report.

Hypohidrotic ectodermal dysplasia (HED) is a rare ectodermal disease with a systemic expression. Oral abnormalities are common and may include hypodontia and shape irregularities in the primary and permanent dentitions. Rehabilitation of the dental arches in pediatric patients with HED is a challenge because HED is a multifactorial disease that demands a complicated treatment approach and most dentists have limited experience or training in the necessary treatment.

The effect of titanium topography features on mesenchymal human stromal cells' adhesion.

Objective: The aim of this study was to evaluate the effect of two kinds of dental implants surfaces with their own characteristics on human marrow stromal cells' adhesion.

Material And Methods: Fifty-six titanium discs (28 machined and 28 acid etched) were used. Machined (MS) and acid-etched surfaces (ES) were analyzed using a scanning electron microscope, energy dispersing spectroscopy (EDS), contact angle analysis and human marrow stromal cells' culture.

On the accuracy of some in vitro models for mechanical studies of maxillary removable partial dentures.

Objectives: Comparative in vitro/in vivo studies show wide differences in functional strain magnitudes and patterns of functional strain distribution in prosthetic devices. The aim of this study was to evaluate the accuracy of three in vitro models for biomechanical studies of prosthetic devices.

Methods: Strain gages were attached to the test RPDs of six subjects.

A novel sensor for bite force determinations.

Objectives: The clinical usefulness, accuracy and precision of a novel bite force sensor based on force sensing resistors were tested in six subjects wearing maxillary removable partial dentures retained by conical crowns.

Methods: The surfaces of the sensor were manufactured in a silicone material that had mechanical properties similar to those of tough foodstuffs. In two separate series of standardized bite force tests, submaximum force levels were recorded with the sensor and with a strain gaged bite fork.

Reflection photoelasticity: a new method for studies of clinical mechanics in prosthetic dentistry.

Objectives: This research was conducted to demonstrate the effectiveness of reflective photoelasticity as an in vivo technique for monitoring the strain/stress distribution in prosthetic devices during function.

Methods: Seven subjects were selected for this study and divided into three groups according to the design of the prostheses. The buccal surfaces of the experimental prostheses were coated with a birefringent resin 2mm thick.
