Osstell AB
Osstell AB is a company headquartered in Gothenburg, Sweden that develops, manufactures, and sells devices and accessories used to measure dental implant stability. It was founded in 1999 with the aim of developing and commercializing a device that utilized resonance frequency analysis (RFA) to determine the level of stability of a dental implant. Patented technology In a dental implant procedure, a hole is drilled into the jawbone and a titanium implant is inserted. If and when the implant has proven to be stable in the jawbone, a prosthetic tooth is then affixed to the implant. Osstell’s patented RFA device (the most recent generation called Osstell IDx) helps dentists assess the stability of the implant, without having to physically disturb it. A small aluminum rod, called a SmartPeg, is placed in the implant. The RFA device prompts vibration in the rod by initiating magnetic pulses of varying frequencies. The RFA device detects the resonance frequency of the rod (called Sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gothenburg
Gothenburg (; abbreviated Gbg; sv, Göteborg ) is the second-largest city in Sweden, fifth-largest in the Nordic countries, and capital of the Västra Götaland County. It is situated by the Kattegat, on the west coast of Sweden, and has a population of approximately 590,000 in the city proper and about 1.1 million inhabitants in the metropolitan area. Gothenburg was founded as a heavily fortified, primarily Dutch, trading colony, by royal charter in 1621 by King Gustavus Adolphus. In addition to the generous privileges (e.g. tax relaxation) given to his Dutch allies from the ongoing Thirty Years' War, the king also attracted significant numbers of his German and Scottish allies to populate his only town on the western coast. At a key strategic location at the mouth of the Göta älv, where Scandinavia's largest drainage basin enters the sea, the Port of Gothenburg is now the largest port in the Nordic countries. Gothenburg is home to many students, as the city includes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dental Implant
A dental implant (also known as an endosseous implant or fixture) is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor. The basis for modern dental implants is a biologic process called osseointegration, in which materials such as titanium or zirconia form an intimate bond to bone. The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic (a tooth, bridge or denture) is attached to the implant or an abutment is placed which will hold a dental prosthetic/crown. Success or failure of implants depends on the health of the person receiving the treatment, drugs which affect the chances of osseointegration, and the health of the tissues in the mouth. The amount of stress that will be put on the impla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resonance Frequency Analysis
Resonance frequency analysis (RFA) is a method used to determine stability (the level of osseointegration) in dental implants. The stability is presented as an implant stability quotient (ISQ) value. The higher the ISQ value the higher the stability. Utilizing RFA involves sending magnetic pulses to a small metal rod temporarily attached to the implant. As the rod vibrates, the probe reads its resonance frequency and translates it into an ISQ value. RFA measurements are used to assess the stability of the implant immediately after placement, as well as to measure the stability during the healing time. This helps the dentist determine if further healing time (osseointegration) is needed before the prosthetic tooth is attached, as well as to identify at-risk patients with compromised bone tissue, or other risk factors. History Resonance frequency analysis was first suggested as an alternative method of analyzing peri-implant bone in a scientific paper by Meredith N et al in 1996. ...

Implant Stability Quotient
The implant stability quotient (ISQ) is the value on a scale that indicates the level of stability and osseointegration in dental implants. The scale ranges from 1 to 100, with higher values indicating greater stability. The acceptable stability range lies between 55 and 85 ISQ.Sennerby L, Meredith N.

Kungsbacka
Kungsbacka () (old da, Kongsbakke) is a locality and the seat of Kungsbacka Municipality in Halland County, Sweden, with 19,057 inhabitants in 2010. It is one of the most affluent parts of Sweden, in part due to its simultaneous proximity to the countryside and the large city of Gothenburg. Its mayor since 2020 is Lisa Andersson. History The first records referring to Kungsbacka as a town date from the 15th century, when it was part of Denmark. By the time it was recognised as part of Sweden (1658), the river running through the town, on which some transportation of goods took place, was almost completely overgrown and despite pleas to restore its function, this did not occur. Some trade still took place from the coast, but the town's significance as a place of naval commerce lessened over the centuries. Today, it is the home of over 2,000 enterprises, and the river is still running through it. A devastating fire in 1846 destroyed the town centre, sparing only a little red woode ...

Vänersborg
Vänersborg () is a locality and the seat of Vänersborg Municipality, Västra Götaland County, Sweden with 23,882 inhabitants (out of a municipal total of 39,591) Until 1997 it was the capital of Älvsborg County, which was dissolved in 1998. Since 1999 Vänersborg has been the seat of the regional parliament of Västra Götaland County. The city is located on the southern shores of lake Vänern, close to where the river Göta älv leaves the lake. History A marketplace was established at Brätte at the southern end of Vassbotten (southernmost part of Vänern), south of modern Vänersborg, by the end of the medieval period. The settlement developed with paved streets lined with houses and farms and it was granted town privileges in 1580. The site, however, became unsuitable for trans-shipment of goods due to silting of its harbour and it was difficult to protect. Consequently, in 1644, the town was moved 3½ kilometres north to Huvudnäset, and the new town of Vänersborg was es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Medical Technology Companies Of Sweden
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
