The purpose of this study was to evaluate the new bone formation and biodegradability of various bone fillers placed underneath a nonresorbable membrane (expanded polytetrafluoroethylene [e-PTFE]) in standardized defects in a beagle dog model. Mandibular premolars and first molars were extracted bilaterally in six adult female beagle dogs. Three months after the extractions, six rectangular def...

BACKGROUND Dermal fillers are increasingly being utilized for multiple cosmetic dermatology indications. The appeal of these products can be partly attributed to their strong safety profiles. Nevertheless, complications can sometimes occur. OBJECTIVE To summarize the complications associated with each available dermal filling agent, strategies to avoid them, and management options if they do ar...

The purpose of this investigation was to examine the effect of filler particle size and shape as well as filler content on light transmittance characteristics and color of experimental composite resins. A mixture of 30 mol% Bis-GMA and 70 mol% TEGDMA was prepared as a base monomer and to which a photoinitiator (camphorquinone) and a co-initiator (N,N-dimethylaminoethyl methacrylate) were added....

Background: Injectable dermal fillers are commonly used by physicians in the treatment of the signs of aging. The most commonly used dermal filler is hyaluronic acid. Skinfill plus (SFP) belongs to the family of monophasic monodensified fillers. In this post-marketing clinical study, we have evaluated the efficacy of SFP for the treatment of facial aging. Methods: The study enrolled 109 patient...

A thin-walled shell and a thick-walled mass (cylinder) in contact with it, made of different material, are structural elements many machines, apparatus, structures. The paper considers forced steady-state vibrations cylindrical structures filled layered viscoelastic material. study aims to determine the damping properties structurally inhomogeneous mechanical system under influence harmonic loa...

Nanoscale inorganic fillers with average particle sizes smaller by an order of magnitude or more compared to those of conventional fillers are becoming commercially available. The efficacy of these fillers used in polymer formulations and particularly their effect as photostabilizers are beginning to be investigated. These may enhance or retard photodegradation depending on the surface coating ...

Abstract Wear rate appraisals are currently indispensable on agro-waste filled composites for brake pads as they predict the expected lifespan of materials. However, existing wear models inaccurate predictions omit inflationary cost In this paper, idea is to account materials and adjust that into a pseudo model. The fillers in an organic matrix create under dry sliding experiments was considere...

BACKGROUND Empty screw holes after hardware removal are stress risers that weaken bone and can lead to refracture in an active individual. We sought to reduce these stress risers. We hypothesize that resorbable screws used as hole fillers would (1) provide immediate strength and (2) maintain this strength during resorption. METHODS Randomized, prospective controlled animal laboratory study wi...

BACKGROUND The ever-expanding range of dermal filler products for aesthetic soft tissue augmentation is of benefit for patients and physicians, but as indications and the number of procedures performed increase, the number of complications will likely also increase. OBJECTIVE To describe potential adverse events associated with dermal fillers and to provide structured and clear guidance on th...

BACKGROUND The increasing use of injectable fillers has been increasing the occurrence of disfiguring anaerobic infection or granulomas. This study presents two types of laser-assisted evacuation of filler material and inflammatory and necrotic tissue that were used to treat disfiguring facial nodules after different types of gel fillers. MATERIALS AND METHODS Infectious lesions after hydroge...
