NTA IMPLANT
SURFACE: "SLA"
Primary stability and SLA osseointegration
NTA Implant uses an SLA-treated surface and an 11° conical implant–abutment connection specified for primary stability at placement. The fixture is indicated for one-stage protocols and aesthetic sites per IFU. The taper is designed to limit micro-movement and bacterial leakage at the interface.
Surface processing and biocompatibility
The SLA (sand-blasted, large-grit, acid-etched) surface is specified to increase bone–implant contact (BIC).
Macro and micro roughness: Corundum grit-blast and acid etch produce 2–4 μm pits intended to support osseointegration.
Non-porous finish: The surface is not micro-porous, so closed recesses for bacterial colonization are not created. Peri-implantitis risk still depends on hygiene and the IFU.
Surface chemistry: X-ray photoelectron spectroscopy (XPS) confirms a titanium dioxide (TiO2) outer layer on the fixture.
Connection and seal
Connection specified for mechanical stability and a sealed implant–abutment interface:
11° conical connection: The taper is designed for a cold-weld effect between fixture and abutment, limiting micro-movement and micro-leakage at the interface.
Platform switching: The implant–abutment junction is inset toward the fixture axis, a geometry associated with crestal-bone and soft-tissue maintenance.
Hex index: Indexes the abutment so it seats at the specified angle.
Surgical and design features
Placement and restorative handling:
Root form: A root-shaped body intended to distribute occlusal load and reduce contact with adjacent roots during osteotomy and insertion.
Self-tapping threads: Cutting edges form the thread in bone, reducing insertion-torque heat versus a fully tapped osteotomy when used per IFU.
Mount-free: The fixture is carried from the package with a fixture driver — no mount component.
Diameter and length range: Options for documented bone types and anatomic sites per IFU.
Straight–tapered body: Longer fixtures add a straight mid-body so the osteotomy axis is less likely to drift during insertion.
