Nta Fixture
NTA Implant Surface Treatment & Core Features combine SLA macro- and micro-topography for optimal osseointegration, platform switching for crestal bone preservation, and conical connection for bacterial sealing and long-term prosthetic stability. The no-mount system, cutting-edge drilling architecture, and root-form macrodesign support predictable primary stability across narrow (2.1) and regular (2.5) implant platforms.
NTA Implant Surface Treatment & Core Features
The SLA surface is produced by a large grit sand-blasting process with corundum particles that creates macro roughness on the titanium surface, followed by a strong acid-etching bath with HCl at elevated temperatures. This generates 2–4 μm micro pits without forming micro-porosity, reducing bacterial retention and delivering optimal osseointegration performance.
X-ray photoelectron spectroscopy (XPS) shows the surface chemical composition as titanium dioxide (TiO2), ensuring direct and optimal interaction with tissue fluids and cells for stable integration.
Platform Switching
Implant–abutment junction is positioned closer to the center of the implant and away from the bone interface. Combined with conical connection advantages, crestal bone loss is rarely observed in NTA implants.
No-Mount System
Fixture mount has been removed from the standard package to shorten surgery time. A fixture driver is used instead, offering highly durable and easy connection/disconnection capability. Fixture mount can be supplied separately upon clinician request.
Conical Connection
Ensures bacterial sealing, eliminates micro-movement and micro-leakage, preserves crestal bone and prevents abutment screw loosening. Inner hex index guarantees accurate abutment positioning.
Straight Body
As implant length increases, the straight body portion also increases, improving surgical control and placement stability especially in deep sites.
Cutting Edge
Triple-sharp drill geometry allows faster osteotomy with reduced frictional heat, shorter drilling time and minimal postoperative discomfort.
Root Form
Root-shaped macrodesign provides high primary stability, optimal load distribution, easier positioning, and reduced risk of sinus or concave surface perforation.
Implant Platform – Narrow (2.1)
Narrow platform is recommended for limited ridge width and aesthetic zone applications while ensuring optimal stability and precise prosthetic alignment.
Implant Platform – Regular (2.5)
Regular platform offers maximum load capacity for posterior regions and full-arch restorations with superior long-term biomechanical performance.
