A Fully Made-in-Japan Implant Brand

Evolutionary Implant System with Made-in-Japan
Reliability to Meet Expectations for Digital Dentistry

We at Nippon Piston Ring Co., Ltd. offer a fully made-in-Japan dental implant system, the IAT EXA, which has been supported by many dentists. Our devotion for development of made-in-Japan dental implant systems is nothing but to utilize highly reliable Japanese technologies, quickly receive opinions of on-site dentists and patients, and provide feedback for new improvement. And now, an advanced implant system has emerged through great evolution. he “IAT EXA PLUS.” This system enables not only carrier-less implant surgery with its uniquely developed implant driver but also responds to a trend of the times, digital dentistry. Operation tools are carefully improved to realize distinguished operability; and advanced technologies are fused to open up new potentials of implant surgery. This implant system is developed to be truly easy to use for dentists and further help patients. Please try the indubitable quality made possible only by this made-in-Japan implant system.

  • Systematized Product Line

ED Surface

ED Surface is a surface property of a fixture created together with the fixture shape, through electric discharge machining with pure titanium wire electrodes. Micropits with Ra surface roughness values of 1.5 to 2µm are created by electric spark discharge. In these micropits, proteins and cells readily accumulate, which is beneficial for cell growth, proliferation, and differentiation. Also, titanium surfaces are generally covered by titanium oxide, but ED Surfaces have a titanium oxide layer of approximately 1µm which is thick compared to mechanically machined surfaces which have a thickness of only 5 to 10nm. Furthermore, the composition gradually changes from the outer surface to the interior, from titanium dioxide (TiO2) to titanium oxide (TiO) and then to elemental titanium (Ti), a structure of titanium oxides well integrated with the elemental titanium. This thick and strong titanium oxide layer has shown excellent corrosion resistance and its surface has great wettability with body fluids and blood, promoting biological reactions that greatly aid osteogenesis.

Strong Initial Stability

Excellent body design for initial
stability after embedding and
functional consistency

Implant body shapes affect initial stability after embedding and n-use stability. The IAT EXA PLUS has a unique design with a shallow root of 3-mm screw thread under the platform for strong initial fixation after embedding. This system also enables sufficient osteoanagenesis up to the neck of the implant body by applying ED Surface up to the neck. The neck of the implant body with a bevel prevents stress concentration on surrounding periphery bones after application of implants and minimizes absorption of alveolar bones.

Excellent adhesiveness enough to
inhibit intraoral bacterium
propagation

Eight-degree Morse taper connection provides significantly tight fitting with almost no micro gaps between the implant body and the abutment. This design reduces micro-movements during occlusion loading preventing peri-implantitis due to intraoral bacterium propagation and absorption of surrounding periphery bones. Moreover, platform switching ensures an ideal width at the boundary between an implant and an abutment to successfully minimize absorption of alveolar bones.

Treatment

An advanced IT system, digital dentistry, is introduced in response to the trend of implant surgery. This system also enables sufficient osteoanagenesis up to the neck lines of treatment and realizes safe and secure implant surgery according to the diagnostic design. Also, this system enables CAD / CAM production of highly aesthetic and quality prosthesis meeting expectations of patients.

Implant Driver

We discontinued conventional implant carriers and independently developed implant drivers for improvement of visual recognition of the embedding depth and stress reduction during treatment. This improved cutting ability of the drill enables reduction of treatment damage in osteoanagenesis and surgery time.
