Dental implantology has witnessed significant advancements over the past decades, with implant systems evolving to enhance osseointegration, soft tissue management, and overall clinical outcomes. Among these, the Astra OsseoSpeed EV Healing Abutment plays a pivotal role in promoting optimal tissue healing around dental implants. This article explores in depth how the Astra OsseoSpeed EV healing abutment aids in tissue healing, its design features, clinical applications, and benefits, supported by images and videos for clarity.
The Astra OsseoSpeed EV Healing Abutment is a component of the Astra Tech Implant System EV, a well-documented implant system developed by Dentsply Sirona. It is designed to be temporarily connected to an endosseous dental implant during the healing phase following implant placement. Its primary function is to support and shape the surrounding soft tissue, facilitating a favorable environment for healing and subsequent prosthetic restoration.
- Material: Typically made from titanium, ensuring biocompatibility and durability.
- Design: Available in various diameters and gingival heights to accommodate different clinical situations and soft tissue thicknesses.
- Compatibility: Fully compatible with the Astra OsseoSpeed EV implant system, ensuring precise fit and function.
- Temporary Use: Intended for use during the healing phase, usually up to 180 days.
- Ease of Installation: Designed for manual seating with light finger force (5–10 Ncm torque), simplifying clinical handling.
The healing abutment acts as a scaffold for the peri-implant soft tissue, supporting the gingiva during the critical healing phase. By maintaining the soft tissue contour, it preserves the natural emergence profile, which is crucial for esthetic outcomes, especially in the anterior region.
- The abutment's shape and size can be selected based on the soft tissue height measured using an Abutment Depth Gauge EV, ensuring a customized fit that supports optimal tissue adaptation.
- Soft tissue sculpturing around the healing abutment encourages the formation of a stable mucosal seal, which protects the underlying bone and implant interface from bacterial invasion.
By covering the implant platform, the healing abutment protects the internal implant connection from contamination during the healing phase. This barrier function reduces the risk of infection and inflammation, which can compromise osseointegration and soft tissue health.
While the healing abutment primarily influences soft tissue, its use in conjunction with the OsseoSpeed EV implant surface enhances the overall healing environment. The OsseoSpeed surface features a unique nanoscale topography that stimulates early bone healing and accelerates osseointegration, indirectly supporting the soft tissue healing process.
The healing abutment is designed for use in single-stage surgical protocols, allowing the implant to be exposed during healing without the need for a second surgery. This reduces patient morbidity, shortens treatment time, and promotes quicker soft tissue healing.
1. Soft Tissue Measurement: Use the Abutment Depth Gauge EV to measure soft tissue height, selecting the appropriate healing abutment size.
2. Selection of Healing Abutment: Choose the healing abutment diameter and gingival height to match the clinical situation.
3. Installation: Pick up the sterile healing abutment from its blister package using the Hex Driver EV.
4. Seating: Manually seat the healing abutment onto the implant with light finger force, securing it with a torque of 5–10 Ncm.
5. Healing Phase: Allow the soft tissue to heal and adapt around the healing abutment for the prescribed period (up to 180 days).
The Astra OsseoSpeed EV system features a unique implant-abutment connection that allows one-position-only placement of abutments, including the healing abutment. This precise fit minimizes micro-movements and microgaps at the interface, reducing bacterial infiltration and promoting stable soft tissue attachment.
The system incorporates the Astra Tech Implant System BioManagement Complex, a combination of design features including:
- Conical Seal Design: Ensures a tight seal between implant and abutment.
- MicroThread: Minute threads on the implant neck that distribute load and stimulate bone preservation.
- Connective Contour: The shape of the abutment connection that supports soft tissue attachment.
These features collectively contribute to maintaining marginal bone levels and promoting healthy soft tissue healing around the implant.
Understanding the biological processes involved in tissue healing around dental implants is essential to appreciate the role of the Astra OsseoSpeed EV healing abutment.
- Hemostasis and Inflammation: Immediately after implant placement, the healing abutment protects the site while the body initiates clot formation and inflammatory responses.
- Proliferation: Fibroblasts and epithelial cells proliferate, migrating along the healing abutment surface to form a mucosal seal.
- Maturation and Remodeling: The soft tissue matures into a stable, keratinized mucosa that adheres tightly to the abutment and implant neck.
The titanium surface of the healing abutment is designed to be smooth enough to prevent plaque accumulation but also to encourage soft tissue cell attachment. This balance is critical to prevent peri-implantitis and promote a healthy mucosal barrier.
Several clinical studies have demonstrated the benefits of using the Astra OsseoSpeed EV healing abutment in tissue healing and implant success rates.
- Marginal Bone Preservation: Research shows that the microthread design and conical seal reduce marginal bone loss compared to other implant systems.
- Soft Tissue Stability: Clinical trials report improved soft tissue thickness and keratinized mucosa formation around implants using the Astra OsseoSpeed EV healing abutment.
- Reduced Inflammation: Patients treated with this system exhibit lower peri-implant inflammation markers, attributed to the precise implant-abutment interface and effective soft tissue sealing.
- Accurate Soft Tissue Measurement: Always measure soft tissue height carefully to select the correct abutment height, avoiding tissue compression or insufficient support.
- Gentle Handling: Use light finger force during seating to prevent trauma to soft tissue.
- Maintain Sterility: Handle healing abutments with sterile instruments to avoid contamination.
- Monitor Healing: Regularly assess soft tissue healing and adjust treatment plans accordingly.
- Patient Education: Inform patients about the importance of oral hygiene during the healing phase to prevent infection.
The Astra OsseoSpeed EV Healing Abutment is a critical component in the implant healing phase, designed to support and enhance soft tissue healing while protecting the implant site. Its compatibility with the OsseoSpeed EV implant system, combined with innovative design features like the BioManagement Complex and conical seal, ensures predictable tissue stability, esthetic outcomes, and long-term implant success. By facilitating soft tissue sculpturing and minimizing microbial contamination, the healing abutment plays an indispensable role in the overall implant treatment workflow.
Clinicians who utilize the Astra OsseoSpeed EV healing abutment benefit from a simplified, reliable, and biologically sound approach to managing the peri-implant soft tissue, ultimately improving patient satisfaction and treatment predictability.
The primary function is to support and shape the soft tissue around the implant during the healing phase, maintaining the natural gingival contour and protecting the implant interface from contamination.
The healing abutment is indicated for temporary use up to 180 days, depending on the clinical protocol and healing progress.
It is specifically designed to be 100% compatible with the Astra OsseoSpeed EV implant system, ensuring precise fit and function.
The healing abutment is manually seated onto the implant using light finger force and secured with a torque of 5–10 Ncm using a Hex Driver EV.
Key features include the conical seal design, microthreads on the implant neck, the connective contour for soft tissue attachment, and the unique implant-abutment interface that minimizes microgaps and bacterial infiltration.
