Description:

The IMP 874208 Legacy 4 Implant is a short-length, 4.2mm diameter x 8mm titanium fixture featuring a 3.5mm prosthetic platform and a sand-blasted, large-grit, acid-etched (SBM) surface for enhanced osseointegration. It is purpose-built for clinical scenarios with limited vertical bone height—especially in posterior regions or near anatomical landmarks such as the maxillary sinus or inferior alveolar nerve.
Crafted from high-strength Ti-6Al-4V titanium alloy, the implant offers outstanding mechanical durability and fatigue resistance. Its tapered, root-form body is designed to optimize initial engagement, while deep-cut threads ensure robust primary stability—even in low-density (D3–D4) bone or immediate placement situations.
The 4.2mm diameter provides a broad implant-to-bone interface, enhancing force distribution and supporting long-term success despite its compact vertical profile. The SBM surface further accelerates bone adhesion and healing response, promoting reliable early integration.
The internal hex connection delivers a secure anti-rotational prosthetic fit, and the 3.5mm platform supports platform switching to encourage crestal bone preservation and soft tissue stability. Fully compatible with all Legacy 4 restorative components—including abutments, healing collars, scan bodies, and impression copings—it integrates cleanly into both analog and digital workflows.
Whether used for single-unit molar replacement or incorporated into a larger prosthetic plan, the IMP 874208 provides restorative flexibility, surgical predictability, and biomechanical reliability in challenging vertical environments.
