Zenith Apex: Overdenture Implant System
Premium Solution for Stability and Patient Comfort
Overview
Zenith Apex implants are designed specifically for over denture solutions, offering secure, reliable support for patients requiring removable prostheses. Representing top-tier performance, the Apex implant is engineered for advanced cases that demand superior functionality, exceptional durability, and higher stress tolerance, making it an ideal choice for high-end practices.
The Role of Secondary Stability in Implant Success
During primary stability, there is mechanical anchorage at the time of placement. Secondary stability is a crucial phase in the osseointegration process, secondary stability develops biologically over time as new bone forms and matures around the implant. Here, the natural bone tissue is triggered to create an environment around implant surface which securely integrates bone with the implant.
This implant system is meticulously designed to enhance secondary stability, which is critical for long-term success and durability. By leveraging advanced surface treatments and precise geometry, the system encourages robust osseointegration, forming a strong and mature bone-implant interface over time.
Implants engineered with a focus on secondary stability are ideal for delayed loading protocols, where an optimum healing period allows the bone to remodel and achieve a stable, stress-bearing environment. This approach minimizes the risk of micromovements during the healing phase, ensuring optimal long-term outcomes.
Key Features Supporting Secondary Stability:
Design Adaptations:
Thread geometry is optimized to distribute forces evenly, reducing stress on the bone and implant interface. The tapered design ensures smooth insertion, minimizing trauma to the surrounding bone. Self-tapping threads enhance implant anchorage, even in low-density bone situations. Additionally, the thread pitch and depth are engineered to facilitate immediate mechanical stability, minimizing micromovements while promoting gradual load transfer, aiding in long-term secondary stability. These design elements ensure effective load transfer during the healing phase.
Surface Modifications:
The interaction between implant surfaces and bone cells stimulates osteoblast activity, forming new bone around the implant. The surface has nano-structures that support fibrin network formation and mineralization, which helps with the early stages of osseointegration. Enhanced bone-to-implant contact (BIC) for long-term stability is achieved through coated, micro-roughened, hydrophilic surface which accelerates cellular activity, promoting strong bone growth around the implant.
Hydrophilic Coatings:
These coatings attract and retain blood at the implant surface, promoting the migration of proteins and cells involved in bone healing. Hydrophilic implants are particularly effective in reducing healing times and improving integration in low-density bone. Our Implants can achieve up to 30 % faster bone formation compared to conventional implants. This accelerated process improves primary and secondary stability, reducing healing time in clinical practice.
Clinical Advantages:
• Improved durability due to the stable integration of the implant into mature bone.
• Reduced risk of micromovements or implant failure under high stress.
Scientific Backing:
Studies have shown that implants with optimized surface treatments and secondary stability-focused designs demonstrate higher survival rates over extended periods, even in patients with high masticatory loads. For example, research published in The International Journal of Oral & Maxillofacial Implants highlights the role of secondary stability in achieving long-term implant success rates of over 98 % after 10 years. By prioritizing strong secondary stability, this implant system delivers dependable outcomes, ensuring patient satisfaction and practitioner confidence in a wide range of restorative cases.
Healing Period for Optimised Loading:
• Mandible: 12–14 weeks
• Maxilla: 20–22 weeks
