Hypersensitivity to TMJ implant materials is an issue that we are frequently hearing from TMJ patients. Given this concern we contacted Marco Caicedo, Ph.D., Senior Scientists and COO at Orthopedic Analysis in Chicago, IL. Orthopedic Analysis is an independent diagnostics company dedicated to the quantitative analysis of immune responses to biomaterials (i.e metal allergy to implant materials)....

The potential of ultrafast lasers (pico- to femtosecond) in orthopedics-related procedures has been studied extensively for clinical adoption. As compared conventional laser systems with continuous wave or longer pulse, provide advantages such as higher precision and minimal collateral thermal damages. Translation surgical applications the clinic restrained by limitations material removal rate ...

Metallic implants are commonly used in the orthopedic field. Despite the large number of metallic medical devices in use today, they are predominantly make up of only a few metals. Metallic alloys such as titanium continue to be one of the most important components used in orthopaedic implant devices due to favorable properties of high strength, rigidity, fracture toughness and their reliable m...

Osteogenesis around implants is affected by the physical and chemical characteristics of the biomaterials used. The osteoprogenitor cells must migrate to the implant site and synthesize and secrete a mineralizable extracellular matrix. Because this is neo-bone formation, the mechanism by which the cells calcify their matrix involves extracellular organelles called matrix vesicles in a process t...

 longevity of osseointegrated implants are intensely influenced by biomechanical factors. Control of these factors prevents mechanical complications, which include fracture of screws, components, or materials veneering the framework. In this study, the impact of length and threads pitch of dental implants on the stress distribution and maximum Von Mises stress in implant-abutment complex and ja...

background: jaw bone quality plays an essential role in treatment planning and prognosis of dental implants. regarding several available methods for bone density measurements, they are not routinely used before implant surgery due to hard accessibility. objective: an in vitro investigation of correlation between average gray scale in direct digital radiographs and hounsfield units in ct-scan pr...

the highest success rates for any orthopedic medical restorative process. According to Scott D. Ganz, DMD, Maxillofacial Prosthodontist, these success rates perhaps explain one of the barriers to clinicians ordering more computed tomography (CT) scans for prospective implant patients. He explains, however, that “CT imaging can help clinicians improve all aspects of implant reconstruction, inclu...

In this study, a new Kirschner wire (K-wire) design was performed to fix bone fractures in orthopedic surgery. The numerical analyses were completed based on the finite element method (FEM), using Deform-3D software. kind of FEM, friction, material model, load and boundary conditions must be defined correctly. It has been seen that is more advantageous terms implant failure or stability fractur...

BACKGROUND Polyether-ether-ketone (PEEK), cobalt-chromium-molybdenum (CoCrMo), and highly cross-linked polyethylene (HXLPE) are biomaterials used in orthopedic implants; their wear particles are considered to induce peri-implant osteolysis. We examined whether different particle types induce the same degree of peri-implant osteolysis. METHODS Forty female rabbits were randomly divided into fo...
