Biomimetic Implant Design

for Extraction / Immediate

Implant Placement

At Implant Designed to Maximize Stability in Immediate Extraction Sites


Historically, surgical outcomes had been built on a paradigm of placing endosseous implants in healed sites. However, there is an increasing need to place implants at the time of tooth extraction at the patient’s request or to preserve the entire tissue envelope. Unlike healed sites with relatively balanced bone density and soft tissue coverage, extraction sites present additional challenges including determining ideal implant positioning, maximizing initial stabilization, and the consequences of significantly reduced bone-to-implant contact. As a result, there is a need for an implant architecture that improves initial stability in compromised sites and enhances early healing and

defect regeneration.



Are implants designed for placement with healed

site properties the best choice for the conditions

encountered in extraction site defects?

Extraction / Immediate Placement Physical Attributes and Condition.


A substantial portion of an implant body may have minimal or no contact with walls of the extraction site. Therefore, the

archetypical  implant design should maintain axial position and resist migration as it is placed into the defect space.

Initial stability preferably is established at the thread tips rather than implant body. The implant overall architecture  should not over-compress the remaining bone. Its design must minimize micro-fracture and encourage the remodeling phase. An aggressive apical architecture is an important feature to

further enhance initial implant stability.

Architectures Features:


Implant architectures designed for healed sites are usually either highly tapered or straight in  body design. Their body design and thread configurations often encourage bone compression. This may be advantageous in healed sites, especially those with minimal bone density, but not a requisite in extraction site placements.  Cutting vents found on many of these designs not only increase micro-fracture of the bone but also create a loss of surface area due to elimination of threads in the apical zone.

Six Biological Implant features

Ideal for Extraction Site Placement


A modified taper design is specifically engineered to provide maximum initial stability in extraction sites where only a

portion of the implant may be in bone.

Thread Design:

Radial Compression Threads (Patented US and EU) provide optimal bone compression by directing seating forces through the thread tips rather than the implant body.


OSSEAN® Nano-structured surface is impregnated with CaPO4 molecules (more than a thousand times smaller than Nano particles) designed to increase bone cell activity during

the early healing phase.

Cutting Features:

BLOSSOM® (Patent Pending) cuts through bone with

finesse, not force, to reduce bone microfracture and enhance both initial and primary stability. It also generates a physiologic autologous micrograft resulting in increased bone-to-implant contact.

Prosthetic Connection:

A Ferrule connection ensures a stable restorative platform,

especially during the critical provisional/early healing stage where micromotion and microleakage can lead to crestal bone remodeling.

Apical Design:

An apical recess prevents premature “bottoming out” of the implant and gives latitude for additional apical seating in ramped ridges. The elimination of a cutting vent, made

possible by incorporating the BLOSSOM cutting feature, increases surface area and allows for a more aggressive

apical thread section.
