Zahntium Implant ZI 37513 – 3.75mm x 13mm

The Zahntium Implant ZI 37513 is a regular-platform dental implant with a 3.75mm diameter and 13mm length, designed for clinical situations with ample vertical bone height where maximum implant stability is desired. The extended 13mm length provides deep engagement into the alveolar bone, often reaching the bicortical layer for exceptional primary stability. This implant is ideally suited for single-tooth replacement in the canine and premolar regions, as well as for use as an abutment in short-span bridges or overdenture cases.

Manufactured from medical-grade Grade 4 Titanium, the Zahntium ZI 37513 features a tapered body macro-design with self-tapping apical threads that enable smooth, controlled insertion. The 3.75mm diameter represents the regular platform standard, providing excellent compatibility with a wide range of prosthetic components and restorative systems. The tapered geometry creates increasing bone compression during insertion, generating high insertion torque values that correlate with primary stability – a critical factor for successful osseointegration and immediate loading when indicated.

The internal hex connection of the Zahntium ZI 37513 provides a precision-engineered interface for prosthetic attachment. 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 where rotational forces can lead to screw loosening. The internal connection also protects the hex from deformation during implant insertion, preserving the accuracy of the interface for the life of the restoration.

The SLA surface treatment on the Zahntium ZI 37513 creates a micro-rough topography that accelerates the osseointegration process. The sandblasted and acid-etched surface increases surface energy and wettability, promoting the adsorption of proteins and the attachment of osteogenic cells. The micro-rough surface has been shown to enhance osteoblast differentiation and mineralization, resulting in faster and stronger bone-implant integration. Clinical studies have reported high survival rates for SLA-surface implants, with many achieving functional osseointegration within 6-8 weeks.

The 13mm length of the Zahntium ZI 37513 offers significant advantages in terms of stability and force distribution. Longer implants have been shown in systematic reviews to have higher survival rates than shorter implants, particularly in the posterior regions where occlusal forces are highest. The increased surface area provided by the 13mm length reduces stress concentration at the crestal bone level, potentially reducing the risk of marginal bone loss over time. In the anterior mandible, the 13mm length often engages the inferior cortical bone, providing excellent resistance to lateral and torsional forces. Each implant is supplied sterile and ready for immediate surgical placement.
