Evaluating the antifungal effectiveness, leaching characteristics, flexural strength, and impact strength of polymethyl methacrylate added with small-scale silver nanoparticles - An in vitro study.

Aim: (1) To assess the release of stable silver nanoparticles (AgNPs) of small scale dimension added to heat polymerized polymethyl methacrylate (PMMA) in 6 months. (2) Assessing the influence of incorporating minimal concentrations of stable AgNPs with nanoscale dimensions into heat polymerized PMMA over a 6 month period on its antifungal efficacy (AF), flexural strength (FS), and impact strength (IS).

Settings And Design: Incorporating nanoparticles with a very small scale may have minimal impact on mechanical properties due to their diminutive size.

Effect of addition of titanium dioxide nanoparticles on the antimicrobial properties, surface roughness and surface hardness of polymethyl methacrylate: A Systematic Review.

Polymethyl Methacrylate (PMMA) denture-base resins have poor surface properties that facilitates microbial adhesion causing denture stomatitis. This systematic review aims to evaluate the effect of different sizes and percentages of titanium dioxide nanoparticles (TiO2NP) on the antimicrobial property, surface roughness and surface hardness of PMMA denture base resin.  A systematic search of English peer-reviewed articles, clinical trial registries, grey literature databases and other online sources was performed using the PRISMA-S Guidelines for and studies.

Evaluation of Sagittal Inclination of Occlusal Plane and Horizontal Condylar Guidance Using Various Anterior Reference Points on Arcon and Nonarcon Articulators.

Aim: The aim of the study was to determine the effect of different anterior reference points during facebow transfer, on sagittal inclination of occlusal plane (SIOP) and horizontal condylar guidance (HCG) values obtained on arcon and nonarcon articulators.

Materials And Methods: Facebow records of 25 participants were made and transferred to Hanau Wide-Vue (WV) and Hanau H2 (H2) articulators using conventional indirect transfer (CIT), superior annular groove (SAG), and inferior annular groove (IAG) as anterior reference points. Maxillary casts were mounted on each articulator followed by mandibular mountings.

Detachable Palatal Ramp of Teeth to Improve Comfort in a Completely Edentulous Patient with a Segmentally Resected Mandible.

The rehabilitation of a completely edentulous patient with segmental resection of the mandible (without osseous reconstruction) poses a considerable challenge to the restoring prosthodontist. Due to the absence of natural teeth in both arches, it is difficult to correct the mandibular deviation with the aid of guidance prostheses. Prosthetic management of such patients usually consists of a maxillary complete denture and mandibular segmental denture occluding in the deviated position itself.

Correction of deviation of a partially resected mandible using a palatal ramp with the aid of a semi-adjustable articulator.

Patients having undergone hemi-mandibulectomy without further reconstruction (to restore the lost mandibular continuity) suffer functional limitations due to the resultant deviation of the segmental mandible. A palatally based guidance prosthesis (or palatal ramp prosthesis) is often indicated and is usually fabricated chairside in self-cured acrylic resin. Establishing the correct angulation of the slope of the palatal ramp may take several attempts before a satisfactory correction is achieved.

A cephalometric study to determine the plane of occlusion in completely edentulous patients.

Aim: Determination of the plane of occlusion in completely edentulous patients with the help of the ala-tragus line (Camper's plane) may be questioned. An attempt to devise an alternative method to determine the orientation of the plane of occlusion was made.

Materials And Methods: Cephalometric analysis was used to identify whether a correlation exists between the plane of occlusion of dentulous Indian individuals and other stable cranial landmarks.

A cephalometric study to determine the plane of occlusion in completely edentulous patients: part I.

To determine the relationship between the plane of occlusion and the Camper's line (ala-tragus line). Lateral cephalograms of 105 dentulous subjects were obtained after outlining the tragus and the base of the ala of the nose with radiopaque markers. Tracings of the cephalograms were done and the relationship between the plane of occlusion and the Camper's line (ala-tragus line) was noted.
