Vertical ridge augmentation is a demanding and technique-sensitive surgical procedure. In the present case series, cone beam CT (CBCT) scans from the clinical routine of patients treated using a novel approach for vertical bone augmentation were assessed. All patients showed a single-tooth class 5 defect and were treated using a modification of the original shell technique.

The Microbiome and Protein Carbamylation: Potential Targets for Protein-Restricted Diets Supplemented with Ketoanalogues in Predialysis Chronic Kidney Disease.

In chronic kidney disease (CKD), metabolic derangements resulting from the interplay between decreasing renal excretory capacity and impaired gut function contribute to accelerating disease progression and enhancing the risk of complications. To protect residual kidney function and improve quality of life in conservatively managed predialysis CKD patients, current guidelines recommend protein-restricted diets supplemented with essential amino acids (EAAs) and their ketoanalogues (KAs). In clinical studies, such an approach improved nitrogen balance and other secondary metabolic disturbances, translating to clinical benefits, mainly the delayed initiation of dialysis.

Technical Complications of Removable Partial Dentures in the Moderately Reduced Dentition: A Systematic Review.

The aim of this study was to conduct a systematic literature review with a subsequent meta-analysis on the technical complications and failures of removable partial denture (RPD) therapy in the moderately reduced dentition. A systematic literature search of established medical databases, last updated 06/2022, was conducted. RCTs and prospective and retrospective studies were included that had information on technical complications and failures of RPDs, at least 15 participants, an observation period of at least two years and a drop-out rate of less than 25%.

Quantification of MRP8 in immunohistologic sections of peri-implant soft tissue: Development of a novel automated computer analysis method and of its validation procedure.

Background: As manual cell counting lacks objectivity in the assessment of positive marker cells in immunohistologic sections, there has been a shift to automated computer analysis solutions. However, quantifying inflammation around dental implants is still often done by manual cell counting.

Method: With mucosal sections stained against MRP8 harvested around dental implants, we developed an automated method (AM) to identify positive marker cells.

Decentralisation in Times of Crisis: Asset Or Liability? The Case of Germany and Italy During Covid-19.

How did the legal and political-administrative relationship between central and local governments of two decentralised states shape their response to COVID-19? Literature and theories on decentralisation argue that federal and decentralised states are less able to respond to crises in a coordinated manner due to their perceived greater susceptibility to political conflict. Situated within this theoretical debate and based on the analysis of legal acts, political decisions, and relevant national news media articles between March and August 2020 in Germany and Italy, this research note shows that, counterintuitively, more decentralisation does not necessarily translate into more legal and political stress during pandemic management. In responding to the COVID-19 pandemic, Germany, a highly decentralised state, experienced less legal and political tensions than the less decentralised Italy.

Gingival Displacement in the Vertical and Horizontal Dimension under the Condition of Mild Gingivitis-A Randomized Clinical Study.

This randomized clinical study aimed at quantifying the gingival displacement performance in the vertical and horizontal directions of the 3M™ Astringent Retraction Paste (3M Oral Care, Seefeld, Germany) in comparison with the double-cord technique with aluminum chloride as an astringent.

Objectives: Diode lasers and the Nd:YAG laser are used in periodontal therapy and soft tissue surgery. Dental filling materials or cements might be inadvertently damaged. The underlying mechanism of the damage is based on the dental material's specific transmission and thus absorption behavior.

Reliability of light microscopy and a computer-assisted replica measurement technique for evaluating the fit of dental copings.

The aim of this in vitro study was to assess the reliability of two measurement systems for evaluating the marginal and internal fit of dental copings. Sixteen CAD/CAM titanium copings were produced for a prepared maxillary canine. To modify the CAD surface model using different parameters (data density; enlargement in different directions), varying fit was created.

Accuracy of intraoral and extraoral digital data acquisition for dental restorations.

Unlabelled: The computer-aided design (CAD) and computer-aided manufacturing (CAM) process chain for dental restorations starts with taking an impression of the clinical situation. For this purpose, either extraoral digitization of gypsum models or intraoral digitization can be used. Despite the increasing use of dental digitizing systems, there are only few studies on their accuracy.

Glutamine: an obligatory parenteral nutrition substrate in critical care therapy.

Critical illness is characterized by glutamine depletion owing to increased metabolic demand. Glutamine is essential to maintain intestinal integrity and function, sustain immunologic response, and maintain antioxidative balance. Insufficient endogenous availability of glutamine may impair outcome in critically ill patients.

Interaction of titanium, zirconia and lithium disilicate with peri-implant soft tissue: study protocol for a randomized controlled trial.

Background: Against the background of increasing use of dental implants, and thus an increasing prevalence of implant-associated complications, a deeper understanding of the biomolecular mechanisms in the peri-implant tissue is needed. Peri-implant soft tissue is in direct contact with transmucosal dental implant abutments. The aim of this trial is to distinguish the biomolecular and histological interactions of various dental abutment materials with peri-implant soft tissue.

Performance of dental impression materials: Benchmarking of materials and techniques by three-dimensional analysis.

Among other factors, the precision of dental impressions is an important and determining factor for the fit of dental restorations.

Materials And Methods: Two acrylic glass plates, each containing a semi-canal, were bolted together to form a complete canal. This geometry permitted one semi-canal to be filled with fine liver sausage of bovine origin dyed by methylene blue and the other with NaOCl (4.

Glutamine as indispensable nutrient in oncology: experimental and clinical evidence.

Background: In hypermetabolic situations, glutamine is intensively used by rapidly dividing cells such as enterocytes, lymphocytes, and fibroblasts as nitrogen source and/or alternative energy fuel. It is hypothesized that in cancer patients the increased glutamine demands of the host increase the capacity of endogenous production resulting in a strong glutamine deprivation with detrimental effects on organ functions. In long-term periods of cancer cachexia, an adequate nutrition support including glutamine can essentially contribute to cover glutamine needs and, thus, to spare energy reserves of the host and to retard severe complications such as multi-organ failure.
