Zahntium Implant ZI 33115 – 3.3mm x 11.5mm

The Zahntium Implant 33115 is a narrow-platform dental implant featuring a 3.3mm diameter and 11.5mm length, designed for clinical situations requiring enhanced implant stability in soft bone conditions. This implant is particularly valuable for the posterior maxilla, where bone density is often D3 or D4, and for replacing lateral incisors in the maxillary aesthetic zone. The extended 11.5mm length provides deeper bone engagement, distributing occlusal forces over a greater surface area and reducing crestal stress concentration.

Manufactured from medical-grade Grade 4 Titanium, the Zahntium 33115 implant incorporates a tapered body geometry with aggressive, self-tapping threads. The thread design features a deeper pitch than standard implants, creating a larger surface area for bone contact – a critical advantage in low-density bone where primary stability can be challenging to achieve. The self-tapping apex allows for smooth insertion without the need for pre-tapping, reducing surgical time and minimizing bone trauma.

The internal hex connection of the Zahntium 33115 provides a precision-engineered interface for prosthetic components. This hexagonal recess, machined to exacting tolerances, accepts standard abutments and transfer copings, ensuring compatibility with a wide range of prosthetic systems. The internal design protects the hex from deformation during implant insertion, maintaining the accuracy of the connection for future restorations. The anti-rotational feature is essential for single-tooth restorations, preventing the abutment from rotating under functional loads.

The SLA surface treatment on the Zahntium 33115 creates a micro-rough topography that has been extensively studied in dental implantology. This surface texture promotes fibrin retention and blood clot stabilization during the early healing phase, followed by osteoblast migration and differentiation. The result is accelerated bone apposition directly onto the implant surface, achieving secondary stability more rapidly than machined surfaces. In soft bone conditions where healing may be slower, the SLA surface provides a biological advantage that enhances long-term implant survival.

The 11.5mm length of the Zahntium 33115 is particularly advantageous for the posterior maxilla, where sinus pneumatization often reduces available bone height. This length provides sufficient vertical engagement while remaining safely below the sinus floor in many cases. In the mandible, the 11.5mm length offers excellent stability for replacing premolars, engaging the denser cortical bone layers. Each implant is supplied sterile in a sealed vial, complete with a cover screw, ready for immediate placement.
