Implant Materials

Fatigue testing is used in implant dentistry to determine the strength and longevity of an implant system. The governing standards are ISO 14801 – Dynamic Fatigue Test for Endosseous Dental Implants and U.S. FDA Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments. Generally, larger diameter implants with thicker walls have higher strength and fatigue life than smaller diameter implants of the same material. In addition to the diameter size, the material type plays a major role in increasing the strength and fatigue limit of implants. The ability of titanium and titanium alloy to resist corrosion is a result of the formation of an insoluble and continuous titanium oxide (TiO2) layer on the surface (Figure 1). The titanium oxide layer prevents oxygen penetration, protects the material from any impurities and permits a compatible layer of biomolecules to attach. The excellent biocompatibility of titanium and titanium alloy is the result of the nature of this surface layer.

All BioHorizons titanium implants and prosthetic components are made from Ti-6Al-4V ELI (Grade 23), a higher-purity (“Extra- Low Interstitial”) version of Ti-6Al-4V. The lower limits of iron, carbon and oxygen (Table 1) improve ductility, fracture toughness, and fatigue crack propagation. This alpha-beta titanium alloy has superior damage and mechanical properties compared to pure titanium and standard grade Ti-6Al-4V. In comparison, Commercially Pure (CP) titanium comes in 4 Grades. The difference between Grade 1, which is fully annealed, and Grade 4 titanium is the amount of cold work performed to increase the strength (Table 2). While the tensile strength of CP titanium can be improved by a cold-work process, this procedure makes the material more brittle. Because of the complex loading found in implant dentistry, brittle failure of higher grades of CP titanium must be considered.

Basic principles, diagnostics and planning implant therapy, implantology and prosthetics

Dear Professionals,

organized by Vesica, and supported by Biohorizons we are again giving you a unique opportunity to acquire the necessary practical skills for starting and advancing oral surgery and implantology. Together with Dr. Danco Bizevski we invite you on another journey in contemporary implantology.

Day 1

Opening Session and Dinner
Introduction, History and development of Implantology, Engineering Aspects in
Implantology, Misbelieves and the Paradigms of Contemporary Implantology.

  • How did we get here.

Day 2

09:00 – 14:00
Fundamentals of Oral Surgery and Implantology Anatomy of head and neck, Surgical topography, Sterilization, Septic and Aseptic conditions.

Diagnostics: Treatment planning and management of Implantology Surgical Protocols: Immediate and mediate implantation, Augmentative techniques, Complications and treatment of complications, Healing abutments placement, Temporary and Final prosthetics constructions.

  • Revision from medical high school to specialization in implantology.

14:00-15:30 LUNCH

Implant Surgery Hands-On Workshop
Introduction, Simulation of patient and surgery field preparation, Animal jaw surgery demonstration, incision and mucoperiostal flap, drilling and implant placement hands-on, augmentation techniques and sutures, Practical demonstration
of surgery set TSK3000, Placement of 4 implants by each attendee. Complications through examples and solutions.

  • Practical Training on models and animal jaws. Drill the bone, feel the “osseointegration”. Why not you put 4 implants together.

Day 3

09:00 – 14:00
Implant-Prosthetics hands-on Workshops
Introduction in implant prosthetics protocols; BioHorizons prosthetics products presentation; Healing abutments placement; impressions, temporary coronas;

Spiralock® is a superior fastening technology ideally suited for threaded joint applications subjected to heavy shock and vibration, extreme temperatures, long hours of strenuous operation, and millions of loading cycles. This proprietary internal thread form, used in orthopedics and the aerospace industry, is incorporated in all BioHorizons Implants and features a unique 30° wedge ramp at the root of the thread that locks the abutment screw securely to the implant, and spreads the load throughout the entire threaded connection.
The Spiralock® thread configuration provides numerous advantages over standard thread designs:

1. Superior resistance to dynamic loading
2. Improved joint integrity
3. More evenly distributed load
4. Consistent reusability
5. Elimination of secondary locking devices

A conventional abutment screw V-thread is axially loaded versus a Spiralock® thread form that distributes the load radially. This uniform thread loading reduces load and stress concentration at the first engaged thread, significantly increases the strength of the connection and prevents fatigue failure.

That is what distinguishes BioHorizons.
