Zahntium Implant ZI 375115 – 3.75mm x 11.5mm

The Zahntium Implant ZI 375115 is a regular-platform dental implant with a 3.75mm diameter and 11.5mm length, designed for clinical situations requiring enhanced stability and bone engagement. The 11.5mm length provides deeper penetration into the alveolar bone, engaging the denser apical cortical layer for superior primary stability. This implant is suitable for a wide range of indications, including single-tooth replacement in the premolar and canine regions, as well as for use in short-span bridges and overdenture applications.

Manufactured from medical-grade Grade 4 Titanium, the Zahntium ZI 375115 features a tapered body macro-design with aggressive, self-tapping threads. The thread pitch is optimized for rapid insertion while maintaining high insertion torque values, even in low-density bone such as the posterior maxilla. The tapered geometry creates increasing bone compression as the implant advances, generating the frictional forces necessary for primary stability – a critical prerequisite for successful osseointegration and immediate loading protocols.

The internal hex connection of the Zahntium ZI 375115 provides a precision-milled interface for prosthetic components. This hexagonal recess is machined to exacting tolerances, ensuring a friction-fit connection that minimizes micro-movement at the implant-abutment junction. The anti-rotational design prevents abutment rotation under functional loads, a critical feature for single-tooth restorations. The internal connection also protects the hex from deformation during implant insertion, maintaining the accuracy of the interface for future prosthetic procedures.

The SLA surface treatment on the Zahntium ZI 375115 creates a micro-rough topography that accelerates the osseointegration process. The sandblasting step creates macro-roughness that promotes mechanical interlocking with bone, while the acid-etching step creates micro-roughness that enhances osteoblast attachment and differentiation. This dual-level surface texture has been shown to achieve higher bone-to-implant contact ratios and faster healing compared to machined surfaces. For implants placed in poor-quality bone, the SLA surface provides a biological advantage that improves long-term survival.

The 11.5mm length of the Zahntium ZI 375115 offers significant advantages in terms of stability and force distribution. Longer implants have been shown in clinical studies to have higher survival rates, particularly in the posterior regions where occlusal forces are highest. The increased surface area provided by the 11.5mm length reduces stress concentration at the crestal bone level, potentially reducing the risk of marginal bone loss over time. This implant size is an excellent choice for clinicians who prefer longer implants for enhanced stability, provided that adequate vertical bone height is present. Each implant is supplied sterile and ready for immediate surgical placement.
