OBJECTIVE Dental implants anchor in bone through a tight fit and osseo-integratable properties of the implant surfaces, while a protective soft tissue seal around the implants neck is needed to prevent bacterial destruction of the bone-implant interface. This tissue seal needs to form in the unsterile, oral environment. We aim to identify surface properties of dental implant materials (titanium...

STATEMENT OF PROBLEM Zirconia implants have been used for oral rehabilitation; however, evidence of their ability to maintain crestal bone and periimplant soft tissue health is not clear. PURPOSE The purpose of this systematic review was to evaluate crestal bone loss (CBL) around zirconia dental implants and clinical periimplant inflammatory parameters. MATERIAL AND METHODS The focus questi...

We demonstrate the generation of an intense soft-x-ray-laser beam by saturated amplification of high harmonic seed pulses in a dense transient collisional soft-x-ray-laser plasma amplifier created by heating a titanium target. Amplification in the 32.6 nm line of Ne-like Ti generates laser pulses of subpicosecond duration that are measured to approach full spatial coherence. The peak spectral b...

PURPOSE The aim of this study was to evaluate the treatment outcome of implants placed in the maxillary anterior segment. MATERIALS AND METHODS Patients were treated with bone-level implants (Straumann Bone Level Implant, Institut Straumann) that supported all-ceramic single crowns and were followed for 2 to 4 years. Titanium or ceramic abutments were used according to the quality of the soft...

Many dental implants fail due to the infection and inflammation that walk hand in hand with poor healing and soft tissue integration. Titanium surfaces were nanocoated with quercitrin, a natural flavonoid, with the aim to improve soft tissue integration and increase dental implants success. Streptococcus mutans attachment and biofilm formation was analysed. Then, the anti-inflammatory propertie...

the aim of this animal study was to evaluate the possible effects of carbonated soft drink consumption on the rate of orthodontic tooth movement in rats.thirty-six adult male sprague-dawley rats were randomly divided into two experimental groups and one control group. in the experimental groups (a&b;), the water in the dietary regimen was replaced with soft drinks (fanta® in group a and cola® i...

The study aimed to evaluate the effect of different mucosa thickness and resiliency on stress distribution of implant-retained overdentures using a two-dimensional finite element analysis. Models were used in order to simulate two situations. In group A, model represented an edentulous mandible supporting an overdenture retained by two-splinted-implants connected with bar-clip system while in g...

The most frequent abdominal pathology requiring emergent surgery is acute appendicitis. Laparoscopic appendectomy has been performed for the treatment of acute appendicitis since 1983. Closure of the appendix stump is vital to prevent severe postoperative complications. Different methods are described for closure such as stapler, endoloop, titanium clips, non-absorbable polymer clips (hem-o-lok...

BACKGROUND Deep venous surgery is a challenging field with limited indications. Femoral vein duplication (FVD) is a frequent anatomical variant (55% prevalence). The aim was to describe a simple technique for managing deep venous reflux in FVD, when just one of the two segments exhibits deep venous reflux. METHODS The technique consists of closing the refluxing femoral branch with a titanium ...

BACKGROUND Some patients with chronic middle ear disease and multiple failed revisions, who also need a hearing aid, may benefit from an active middle ear implant. An advantage of an active middle ear implant is that the ear canal is unoccluded. METHODS Following extensive experimental development in temporal bones and investigations of various locations and attachments of a Vibrant Soundbrid...
