Dental implants offer a reliable and long-lasting solution for missing teeth, providing both functional and aesthetic benefits. These artificial tooth roots, typically made of titanium, are surgically placed into the jawbone to serve as a sturdy foundation for replacement teeth such as crowns, bridges, or dentures. An implant system known for predictable outcomes is recommended for success. Astra Tech OsseoSpeed is a leading implant system in restorative dentistry, designed to support natural healing.
What is Astra Tech OsseoSpeed?
Astra Tech OsseoSpeed is a dental implant system developed by Dentsply Sirona, engineered to promote optimal bone integration and stability. It consists of screw-shaped dental implants made from Grade 4 titanium. These implants are designed for use in one- and two-stage surgical procedures, addressing situations with missing teeth in either the upper or lower jaw.
This system is indicated for various clinical scenarios, including immediate placement into extraction sites or in cases with a partially or completely healed alveolar ridge. It is also designed for use in soft bone applications where other implant surface treatments might be less effective. The OsseoSpeed system includes the implants, cover screws, transmucosal abutments, and other prosthetic and surgical instruments.
Key Features and Design Principles
The Astra Tech OsseoSpeed implant system incorporates several unique features that contribute to its performance. The OsseoSpeed concept centers on a chemically modified titanium surface, achieved through a patented grit blasting technique followed by treatment in diluted hydrofluoric acid. This process creates a nanoscale topography on the implant surface, designed to stimulate early bone healing and accelerate bone formation, leading to stronger bone-to-implant bonding.
A distinct feature is the MicroThread design on the implant neck, which refers to minute threads at the coronal portion. This design provides optimal load distribution and reduces stress on the surrounding bone, particularly at the marginal cortical bone. This biomechanical bone stimulation helps preserve crestal bone, an important factor in long-term implant success. The conical connection between implants and abutments, known as Conical Seal Design, further enhances stability by transferring loads deeper into the bone and minimizing micro-movements and micro-leakage.
Benefits for Patients
The design principles of Astra Tech OsseoSpeed translate into several patient benefits, primarily focusing on long-term stability and predictable outcomes. The unique fluoride-modified surface of the OsseoSpeed implant encourages faster and more robust bone formation, which can lead to quicker healing times after implant placement. This accelerated bone healing contributes to enhanced primary stability, providing a solid foundation for the dental restoration.
The MicroThread design, by distributing loads effectively and reducing stress on the surrounding bone, helps to maintain the marginal bone level around the implant. This preservation of bone tissue reduces the risk of bone loss over time, contributing to the longevity of the implant. Additionally, the stable soft tissue support facilitated by the implant’s design leads to improved aesthetic outcomes, as the gum tissue around the implant is better maintained.
The Implant Placement Process and Aftercare
Patients considering an Astra Tech OsseoSpeed implant begin with an initial consultation, which includes a thorough examination and may involve X-rays or 3D scans to assess oral health and jawbone density. If sufficient bone mass is not present, a bone grafting procedure may be performed before implant placement to ensure adequate support.
Once the patient is deemed a suitable candidate, the titanium implant post is surgically placed into the jawbone, usually under local anesthesia. A healing period follows, during which the implant integrates with the bone through osseointegration, which can take several months. After successful integration, an abutment is attached to the implant, and a custom-made crown, bridge, or denture is secured to the abutment, completing the restoration.
Maintaining the implant and overall oral health requires consistent aftercare. This includes regular brushing twice daily with a soft-bristle toothbrush and daily flossing, paying careful attention to the area around the implant. Using an antibacterial mouthwash helps prevent plaque buildup. Regular dental check-ups are important for monitoring the implant’s health and ensuring its long-term success.
