What Are Types of Implants?
Implants used to be produced mainly in a thin, flat plate shape called a "blade" 20 years ago, but this has changed and they have evolved into a cylindrical shape that closely mimics the anatomy of a natural tooth root in modern dentistry. While there are still some types of implant that are cylindrical, they are rare, and the plate-shaped ones are completely discontinued.
Currently, most of the implants used and successfully applied worldwide are those that mimic the shape of a natural tooth root. While artificial teeth generally have a similar shape, each implant brand and manufacturer has its own unique surface and shape differences.
Classification of Implant Types can be made in 5 Categories:
♦ Classification according to design
♦ Classification according to connection mechanism
♦ Classification according to macroscopic structure
♦ Classification according to surface
♦ Classification according to material used
Classification Based on Design:
♦ Endosteal implant types (pieces placed inside the alveolar bone)
• Thin flat plate pieces
• Ramus Frame implant types (stainless steel pieces shaped like horseshoes placed inside the jawbone)
♦ Dental root-shaped implant types (most commonly used implant types today)
♦ Superiosteal implants (placed under the periosteum onto the surface of the cortical bone)
♦ Transosteal implants
♦ Intramucosal implants (placed inside the oral mucosa)
Classification According to Connection Mechanism:
♦ Fibrointegration (complete encapsulation of the implant with soft tissue)
♦ Osseo-integration (direct connection between bone surface and implant) This is the most commonly used method.
Macroscopic Classification Based on Structure:
♦ Cylinder tooth-shaped (implants with a cylinder structure)
♦ Toothed implants (the surface of the implant is toothed like a screw, thus increasing the surface area of the implant. This is the most commonly used type)
♦ Plate-type (shaped like a reverse cone)
♦ Perforated tooth implants
♦ Solid dental implants (circular cross-section without any grooves or protrusions)
♦ Vented implants (cylinder-shaped)
♦ Hollow implants (implants with a hollow at the top)
Classification by Surface:
♦ Smooth surface ones
♦ Processed surface ones
♦ Coated surface ones
Classification by Material Used:
♦ Metal implants (titanium is the most commonly used metal, stainless steel and cobalt-chromium are other alternatives.)
♦ Ceramic coated implants (the implant surface is coated with ceramic)
♦ Polymer implants (they can be used as supportive in some cases, not as implants)
♦ Carbon implants (made of stainless steel and carbon)
