Description:

The IMP 873708 Legacy 4 Implant is a 3.7mm diameter by 8mm length implant engineered for use in areas with limited vertical bone height. Featuring a 3.5mm prosthetic platform and a sand-blasted, large-grit, acid-etched (SBM) surface, it supports reliable osseointegration and long-term restorative performance.
Constructed from high-strength titanium alloy (Ti-6Al-4V), the implant provides excellent mechanical strength and fatigue resistance for use in dense bone or posterior regions. Its tapered body mimics natural root anatomy to aid in controlled insertion and initial mechanical engagement. Deep-cut threading enhances primary stability in D3–D4 bone, making it well-suited for immediate placement when appropriate.
The short 8mm length is ideal for anatomically restricted sites such as the posterior maxilla or near critical structures like the sinus floor or mandibular canal. Despite its reduced length, the 3.7mm diameter maximizes bone-to-implant contact area to ensure proper distribution of occlusal loads and implant stability.
The internal hex connection ensures a secure, anti-rotational prosthetic interface, while the 3.5mm platform supports platform switching to promote crestal bone preservation and soft tissue esthetics. Compatible with the full suite of Legacy 4 restorative components—including abutments, impression copings, and final restorations—the implant integrates seamlessly into both conventional and digital workflows.
The IMP 873708 is a dependable solution for clinicians addressing compact spaces while maintaining confidence in primary stability, functional durability, and esthetic harmony.
