PURPOSE It is essential to have sufficient bone bulk and density at the implant site in order to achieve good bone-to-implant contact and primary stability, which are crucial for osseointegration. A new osteotomy preparation technique was recently introduced that uses a bone preservation method that creates a layer of compacted bone along the surface of the osteotomy. The hypothesis of this stu...

OBJECTIVE Vertical bone loss evaluations in the Nobel Biocare Replace(®) Select Tapered (™) implant system in the human after one-year loading time. MATERIALS AND METHODS This retrospective cross-sectional study was performed on 31 patients (14 men, 17 women; mean age, 60.39 years) receiving 170 implants (mean, 5.48 for each patient) of Groovy and Non-groovy designs in the Nobel Biocare Repla...

PURPOSE A satisfactory clinical outcome in dental implant treatment relies on primary stability for immediate load bearing. While the geometric design of an implant contributes to mechanical stability, the nature of the implant surface itself is also critically important. Biomechanical and microcomputerized tomographic evaluation of implant osseointegration was performed to compare alternative ...

Background. Stress distribution plays a vital role in the longevity and success of implant-supported prosthesis. This study evaluated von Mises stress microstrain peri-implant bone implant–abutment junction short dental implants with three different connections splinted unsplinted conditions using finite element analysis (FEA). Materials Methods. In this experimental study, nine transversely is...

BACKGROUND Total knee arthroplasty (TKA) is common, effective, and cost-effective. Innovative implants promising reduced long-term failure at increased cost are under continual development. We sought to define the implant cost and performance thresholds under which innovative TKA implants are cost-effective. METHODS We performed a cost-effectiveness analysis using a validated, published compu...

Dental implants are commonly used in dental therapeutics, but dental practitioners only have limited information about the characteristics of the implant materials they take the responsibility to place in their patients. Manufacturers, scientists and administrations are also lacking of a consensual and clear method and terminology to characterize and control implant surfaces. The objective of t...

OBJECTIVES The aim of the present study was to evaluate the outcome of immediate functional loading of implants in single-tooth replacement using two different installation procedures. MATERIAL AND METHODS One hundred and fifty-one subjects, who required single-tooth rehabilitation in the area of 15-25 and 35-45, were enrolled in eight private clinics in Italy. The implant sites were randomly...

In total hip replacement (THR), bone resorption related to the foreign body reaction around the implant causes bonding failure at the bone-prosthesis interface and adversely affects the function and longevity of femoral implants. Stress shielding is thought to be one of the possible biomechanical factors that causes bone resorption, and is related to prosthesis design. We therefore investigated...

OBJECTIVE Standard treatment of central precocious puberty (CPP) consists of intramuscular or subcutaneous administration of a gonadotropin-releasing hormone (GnRH) agonist (GnRHa) at 3- to 4-week intervals. Although generally effective in suppressing clinical and laboratory parameters of puberty, GnRHa injections are painful, and the need for monthly clinic visits may contribute to poor compli...
