A comparison of mechanic properties regarding complete removable dentures, which were made from polymethylmethacrilate (PMMA) during conventional and CAD/CAM processes. Systemic literature review.

Background: It is not clear if complete removable dentures made during a CAD/CAM process can equate or surpass dentures created during the conventional process in regards of their mechanical properties.

Purpose: To compare mechanical properties of complete removable dentures made from polymethylmethacrilate (PMMA) during a process of CAD/CAM, which are used to help edentulous adult patients, with analogical dentures created from PMMA during the conventional process.

Material And Methods: Data search was conducted regarding PRISMA criteria.

The effect of new acrylic full removable dentures on food taste.

Objective: To find out how the use of new acrylic full upper removable dentures changes the perception of four basic tastes: sweetness, sourness, saltiness and bitterness, and to evaluate the influence of age and gender.

Material And Methods: This study was performed in LSMU MA Faculty of Odontology Department of Prosthodontics during 2017-09-01 - 2018-02-01. All the patients for whom new acrylic upper removable dentures were made were invited to take part.

Stress in the bone and prosthetic components due to "all-on-4" system with polyether-ether-ketone screwing prosthesis. Analysis using 3D finite element method.

Objective: To identify and analyze distribution of bone stress in the implant area using a PEEK prosthesis fixed on four dental implants depending on different positions of the functional loading point on a cantilever in a 3D modeled system.

Material And Methods: The fragment of the lower jaw with dental implants and over-the-implant prosthetic part was represented by geometrical 3D models and diagonal loads were placed on the distal cantilever of the prosthesis. 3D models were exported to SolidWorks® Student Edition 2018 (Dassault Systemes SE, France) software.

The comparison of cement- and screw-retained crowns from technical and biological points of view.

Objective: The aim of this review was to evaluate the most common complications in implant prosthodontics with porcelain-fused-to-metal crowns, to evaluate the influence of biomechanical properties on fractures and cracks of veneered porcelain, and to compare the effects of crowns with different connections on soft tissues.

Material And Methods: A search of literature in the English language between 2009 and 2015 was conducted using the following databases: Medline via PubMed, Science Direct, Wiley online library, Taylor& Francis, and Cochrane library. In total, 10 studies that met the inclusion criteria were found.

In vitro color and roughness stability of different temporary restorative materials.

Objective: The aim of this study was to evaluate the effects of staining solutions on the color stability and roughness of different provisional resin material.

Material And Methods: Three different materials were tested (two polymethylmethacrylate and one bis-acryl composite resins) in cola and coffee and for 1 and 4 weeks. 240 specimens were used - half of them polished and other half not.

Relationship of clinical and microbiological variables in patients with type 1 diabetes mellitus and periodontitis.

Background: The aim of the study was to analyze how metabolic control of type 1 diabetes is related to clinical and microbiological periodontal parameters.

Material And Methods: The study involved 56 subjects aged from 19 to 50 years divided into 2 groups: healthy subjects (the H group), and diabetic (type 1 diabetes) patients with chronic untreated generalized periodontitis (the DM group). The glycosylated hemoglobin value (HbA1c) was determined using the UniCel DxC 800 SYNCHRON System (Beckman Coulter, USA), and the concentration in blood was measured by the turbidimetric immunoinhibition method.

Activity of neutrophil β-glucuronidase in diabetic and nondiabetic patients with chronic generalized periodontitis and healthy subjects.

OBJECTIVE. The aim of the study was to establish the dynamics of β-glucuronidase activity in subjects suffering from type 1 diabetes and chronic untreated generalized periodontitis, subjects suffering from chronic untreated generalized periodontitis only, and control subjects not suffering from generic diseases with healthy periodontal tissue. MATERIAL AND METHODS.

Secretory function of neutrophilic leukocytes of the patients with periodontal diseases.

Aim of study was to examine periodontal status among 20 44 year old patients and to study the secretory function of peripheral venous blood neutrophilic leukocytes (NL) exposed to various antigens and alkaline phosphatase (AP) activity in gingival crevicular fluid (GCF) in patients suffering from gingivitis and periodontitis. Clinically were determined Russell's periodontal index (PI). Secretory function of NL affected by opsonized zymosane, non-opsonized E.

[Effects of periodontitis and opsonized zymosan on chemiluminescence of blood neutrophils].

The objective of the present investigation was to explore oxidative function of parodontitis patient's blood neutrophils stimulated with opsonized zymosan by method of luminol- and lucigenin-dependent chemiluminescence. The leukocytes for this study were obtained from peripheral venous blood of 16 parodontitis patients and 10 healthy subjects. The luminol-dependent chemiluminescence of stimulated neutrophils of parodontitis patients did not differ (p > 0.
