Introduction to Astra EV Healing Abutments

The Astra EV Healing Abutment is a transmucosal component designed for temporary use during the soft tissue healing phase after implant placement or second-stage surgery. It supports the surrounding soft tissue and simplifies the selection of permanent abutments by harmonizing dimensions and providing a predictable healing environment.

Healing abutments are essential to ensure that the soft tissue heals in a way that mimics the final prosthetic profile. Without proper healing abutments, the soft tissue may collapse or heal irregularly, leading to aesthetic and functional complications in the final restoration.

Key Features of Astra EV Healing Abutments

- Conical Seal Design: The Astra EV Healing Abutment features a conical seal connection that ensures a tight, stable fit between the implant and abutment. This design reduces micro-movements and minimizes bacterial infiltration, which are critical factors in preventing peri-implantitis and ensuring long-term implant success.

- Color-Coded and Laser-Etched Bands: Each healing abutment is marked with color-coded bands and laser-etched height indicators. This system allows clinicians to quickly identify the correct diameter and height, streamlining the selection process and reducing chair time.

- Multiple Heights and Diameters: The Astra EV Healing Abutment is available in a variety of heights and diameters to accommodate different soft tissue thicknesses and implant sites. This versatility supports optimal soft tissue contouring and emergence profiles.

- Material Quality: Manufactured from high-grade titanium alloy, these healing abutments provide excellent biocompatibility, strength, and corrosion resistance, promoting favorable tissue response and durability throughout the healing period.

- Compatibility: Designed specifically for the Astra Tech Implant System EV platform, the healing abutments are fully compatible with implants using the EV connection, ensuring seamless integration within the restorative workflow.

The Importance of Healing Abutments in Dental Implantology

Healing abutments serve as a temporary transmucosal extension that shapes and protects the soft tissue during osseointegration. They maintain the soft tissue architecture, prevent tissue collapse into the implant site, and prepare the site for the final prosthetic restoration.

Proper soft tissue healing is critical not only for aesthetics but also for the long-term health of the implant. The peri-implant mucosa acts as a biological seal, protecting the underlying bone and implant from bacterial invasion. The Astra EV Healing Abutment supports this seal by maintaining the soft tissue in the correct position and contour.

Benefits of Using Astra EV Healing Abutments

- Soft Tissue Support and Sculpting: The design of the Astra EV Healing Abutment closely mimics the shape of the final prosthetic abutment. This encourages natural soft tissue healing and helps develop an esthetic emergence profile that blends seamlessly with adjacent teeth and soft tissues.

- Simplified Workflow: The color coding and laser markings enable clinicians to select the correct abutment quickly and confidently. This reduces chair time and the risk of errors during surgery, improving overall clinical efficiency.

- Predictable Healing Outcomes: The conical connection and precise fit minimize microgaps between the implant and abutment. This reduces the risk of bacterial colonization and inflammation, leading to healthier peri-implant tissues and more predictable healing.

- Versatility: Astra EV Healing Abutments are suitable for various clinical situations, including single-tooth implants, partial edentulism, and full-arch restorations in both maxillary and mandibular arches. Their range of sizes and heights enables customization to patient-specific anatomy.

Clinical Applications and Workflow with Astra EV Healing Abutments

Step 1: Selection and Measurement

Before placing the healing abutment, clinicians measure the soft tissue height using the Abutment Depth Gauge EV, which corresponds with the laser-etched bands on the healing abutment. This ensures the selection of an abutment that matches the mucosal height for optimal tissue support.

Accurate measurement is critical because an abutment that is too short may cause tissue collapse, while an abutment that is too tall can cause pressure on the soft tissue, leading to discomfort or ischemia.

Step 2: Placement

The sterile Astra EV Healing Abutment is picked up directly from the blister pack and manually seated into the implant using a Hex Driver EV. Light finger force (5–10 Ncm) is applied to secure it, avoiding over-tightening that could damage the implant or tissue.

The conical seal design ensures a tight and stable connection, which is essential for minimizing micro-movements during the healing phase.

Step 3: Healing Phase

The healing abutment remains in place during the osseointegration period, typically 6 to 8 weeks, allowing the soft tissue to mature around the abutment, forming a natural and esthetic emergence profile.

During this period, patients should maintain good oral hygiene and follow post-operative care instructions to support optimal healing.

Step 4: Abutment Removal and Final Restoration

After healing, the healing abutment is removed, and the soft tissue height is registered to select the permanent abutment. The Healing Uni EV design supports the final abutment configuration, ensuring a smooth transition and matching soft tissue contour.

The final abutment and prosthetic restoration are then placed, benefiting from the well-shaped and stable soft tissue architecture developed during healing.

Advantages of Astra EV Healing Abutments Over Other Systems

The Astra EV Healing Abutment's conical seal connection is a major advantage. This design reduces microgaps that are common in other systems using flat-to-flat or external hex connections. Microgaps can harbor bacteria, leading to inflammation and peri-implant bone loss. By minimizing these gaps, Astra EV healing abutments promote healthier peri-implant tissues.

Moreover, the color coding system is a simple yet effective innovation. It allows clinicians and assistants to quickly identify the correct abutment size without confusion, which is especially useful in busy clinical settings.

Soft Tissue Management and Esthetic Outcomes

One of the most critical factors in implant success is the management of soft tissue around the implant site. The Astra EV Healing Abutment is designed to support and shape the peri-implant mucosa to create an emergence profile that mimics natural teeth.

Emergence Profile

The emergence profile refers to the contour of the tooth or restoration as it emerges from the gingiva. A well-formed emergence profile is essential for aesthetics, especially in the anterior region.

By using healing abutments that replicate the shape of the final abutment, Astra EV helps the soft tissue heal in the desired shape, reducing the need for extensive tissue manipulation during the final restoration phase.

Tissue Stability

The tight connection between the implant and healing abutment also contributes to tissue stability by preventing bacterial contamination and micro-movements that can disrupt healing.

Studies have shown that implants restored with conical connection systems like Astra EV have less marginal bone loss and better soft tissue stability compared to other connection types.

Patient Comfort and Post-Operative Care

The Astra EV Healing Abutment is designed to be comfortable for patients during the healing phase. Its smooth titanium surface and precise fit reduce irritation and inflammation.

Post-Operative Instructions

- Maintain excellent oral hygiene around the healing abutment using gentle brushing and antimicrobial rinses as recommended.

- Avoid applying excessive pressure or trauma to the healing site.

- Attend follow-up appointments to monitor healing progress.

Patients often report less discomfort and better healing outcomes with Astra EV healing abutments compared to generic or less precise components.
