OBJECTIVES The aim of this study was to compare the color stability of three acrylic based hard liners (Ufi gel hard, Dura-Liner II, Tokuso Rebase) and two silicone based soft liners (Ufi gel permanent, Molloplast B) by using the colorimeter. METHODS Sixty disc-shaped samples, with uniform size of 10 mm diameter and 2 mm in thickness were fabricated for each material. Thirty samples were made...

BACKGROUND AND OBJECTIVE Chemical cleansing by denture cleansers is first choice for denture plaque control. The most common problems while using denture cleansers are hardening, porosity, odor sorption, water sorption, solubility, and colour change, bacterial and fungal growth. Chemical cleansing procedures have been found to have an effect on the physical and mechanical properties of denture ...

STATEMENT OF PROBLEM Various surface treatments of zirconia have been recommended for veneering ceramics. However, it has not been determined which of these treatments produces the highest bond strength. PURPOSE This study examined the effects of various surface treatments on the shear bond strength of zirconia and veneering ceramic. MATERIAL AND METHODS Square-shaped (5 × 10 × 10 mm) zirco...

We analysed the results of different strategies in the revision of primary uncemented acetabular components reported to the Norwegian Arthroplasty Register. The aim was to compare the risk of further acetabular revision after isolated liner exchange and complete component revision. The results of exchanging well-fixed components were also compared with those of exchanging loose acetabular compo...

The treatment of phantom pain is frequently dissatisfying. We wanted to find out whether an electromagnetically shielding stump stocking interwoven with metal (medipro(R)Liner RELAX [medi Bayreuth, Bayreuth, Germany]) could have a positive effect on phantom pain. A double-blind, randomized, crossover trial in a total of 30 leg amputees compared the experimental (=verum) silicon liner (VL) fitte...

Oxidised zirconium (OxZi) has been developed as an alternative bearing surface for femoral heads in total hip arthroplasty (THA). This study has investigated polyethylene wear, functional outcomes and complications, comparing OxZi and cobalt-chrome (CoCr) as part of a three-arm, multicentre randomised controlled trial. Patients undergoing THA from four institutions were prospectively randomised...

AIM This study evaluated the antibiofilm effect of an experimental solution of 2% Ricinus communis (R. communis) on a silicone-based denture liner by means of a randomized clinical trial, as well as the integrity of such liner following a cleansing regimen with such solution. MATERIALS AND METHODS About 30 complete denture wearers had their lower dentures relined with a silicone-based denture...

This study suggests that contemporary modular acetabular shell designs employing ceramic liners deform during implantation where acetabular bed under-reaming is employed. The liner retention strength did not degrade by comparison to non-deformed shells using ASTM static push-out methods. A larger question, however, is the influence of this deformation on liner retention strength over time when ...

a resilient soft liner (rsl) has been used in processed complete dentures but controlling its thickness has always been a challenge because of uneven reduction of the denture's intaglio surface. use of a thermoplastic vacuum-formed template and an endodontic k-file, as guides, for the reduction of a processed mandibular complete denture to receive rsl is described in the present report. a proce...

We report results from the first mid-infrared spectroscopic study of a comprehensive sample of 33 LINERs, observed with the Spitzer Space Telescope. We compare the properties of two different LINER populations: infrared-faint LINERs, with LINER emission arising mostly in compact nuclear regions, and infrared-luminous LINERs, which often show spatially extended (non-AGN) LINER emission. We show ...
