Schematics of the variable apatite/collagen preferential orientations with different masticatory conditions

The masticatory load applied to the natural teeth works to align the orientation of the surrounding collagen fibers and the biological apatite (BAp) crystal with the loading direction. Thus, this preferential orientation is responsible for improving bone quality.

Schematics of apatite/collagen preferential orientations around the implant

A study has reported that the loading spectrum controls the preferential orientation of the biological apatite (BAp) crystal and collagen fibers. Different preferential orientations are reported around the upward and downward grooves, as shown in the figure on the right. Furthermore, the stress is continuously transmitted under the load by the upward grooves.

FINESIA’s thread has been designed to achieve long-term stability and control the biological apatite crystal and collagen fiber alignment of bone against a load, which is expected to help improve bone quality, based on joint research results.

Product

Prosthetic Parts

Extensive lineup of parts for more diversified and sophisticated prosthetic design.

As the concept of implant prosthesis changes and CAD/CAM technology advances, prosthetic designs are becoming increasingly diversified and sophisticated. Our product lineup offers a variety of parts, not only for cement and screw retained restorations and overdentures, but also for CAD/CAM restorations.

Function

Healing chamber and insertion torque.

The implant cavity is prepared so that its wall line lies right between the inner and the outer thread of the implant body to form a healing chamber for blood clots to be trapped within it.

Root Tip

Surface Treatment

HA Coating

The results of the reverse rotation removal torque test suggests early osseointegration of HA-coated implants, and the calculated percentage of the bone-to-implant contact area was higher in HA-coated implants. The SEM image confirmed good osseointegration between the HA coating layer and highly calcified newly formed bone.
In the simulated body fluid soaking test, deposition of the crystalline phase, which was presumed to be an HA layer, was observed in minute areas on the surface at four hours of immersion, and this crystalline phase showed growth over time.

Anodizing surface treatment

The surface is anodized to form a 130-nm thick oxide layer, which has excellent properties, including enhanced intraoral esthetics by the coloration.

Other Features

Universal drilling system

As universal design is adopted in the implant body shape, the same technique can be applied for drilling.
Accurate and efficient cutting technology based on Kyocera Industrial Tool department technology has been adopted to create a high quality drill.

Packaged for smooth opening and closing

The outer shrink package can be opened in one step and the implant body is sealed in an aluminum pack designed to protect it from moisture.

Unique implant case

The implant case, common for all implant types (BL/TL/1P), contains a cover cap and can be handled with one hand. It also has a unique stand and slide cover (except 1P).

Safety Stopper

The stopper, available in 1-mm incremental lengths, fits all drills, ranging from pilot drills to final drills, to ensure safe and accurate drilling. A dedicated case is also available for easy selection of stopper and fitting with a single action.
