Dental Implants
Popular categories
The surface texture of a dental implant determines how quickly and smoothly the implant integrates into a jaw bone. Studies indicate that the surface of a dental implant needs to be more than just “rough.” Several surface characteristics impact the rate of integration. MicroBlasting controls two of these characteristics: Ra, the size of the surface peaks and valleys; and the developed surface, or the amount of surface area created through the texturing process.
Manual or Automated Blasting
Dental implants can be textured manually using a standard microblasting system like Comco’s AccuFlo and ProCenter Plus. This is ideal for lower volume processing as it it more labor intensive than an automated system.
Automated systems provide faster throughput, greater precision, and higher repeatability than can be accomplished manually.
Recommended approach
- Nozzle: 0.046″ or 0.060″
- Pressure: 90 psi
- Abrasive: 100 µ Aluminum Oxide or 300-435 µ Hydroxyapatite
- Orifice: 0.040″
Creating a specified Ra finish through automation
A textured finish improves osseointegration, but what exactly is “rough enough” and how can you consistently achieve the same results?
Automated systems produce the most consistent and repeatable surface textures on dental implants. Automated systems are capable of creating surfaces as smooth as 10 µin or as rough as 200 µin. Comco technology in particular allows for careful control over particle velocity and coverage to create a consistently uniform surface.
Precise delineation without masking
Maintaining a smooth surface on the apex of the implant helps prevent bacteria growth where the implant sits at the gum line. Any method used to roughen the surface of the threads must not affect this area.
Comco’s automated microblasting platforms achieves full coverage with a transition zone of 0.007″.
