Titanium and its alloys are widely employed materials for implants in orthopedic or dental surgery due to their mechanical properties, resistance to corrosion and osseointegration capability. However adverse reactions at the tissue/implant interface may occur, which limit the success of the osseointegration process. Therefore, different strategies have to be used to overcome these drawbacks. In this work, we developed two different liposome-based coatings on titanium surfaces as drug or bioactive molecule deposits for dental/orthopedic implant applications...

BACKGROUND: The sinus lift (or sinus augmentation) is a common procedure to improve maxillary bone stock before dental implantation. Chronic rhinosinusitis (CRS) is a potential complication of this procedure and may be refractory to medical treatment. Functional endoscopic sinus surgery has previously been used to address CRS, however, results of previous studies indicated that implant removal is required. There are limited follow-up data available. OBJECTIVE: The purpose of this study was to characterize the long-term outcomes and efficacy of endoscopic sinus surgery for refractory CRS after sinus lift, including the ability to salvage dental implants...

BACKGROUND: Piezo-surgery represents a novel alternative technique. The Piezo-surgery is well tolerated and permits a large number of applications in decribed literature. The principle of piezo-surgery consists into inducing micro-vibrations to a metallic insert with a particular custom. The aim of this article is to study and to evaluate the use of Nobelactive implants in combination with piezosurgical split-crest technique in severe atrophy of the upper maxilla. This approach allows avoiding the use of onlay grafts, due to rise the trasversal width of the crestal bone, which could have more complications and uncertain prognosis...
