In a recent EAO "Just Ask" session, Dr. Stavros Pelekanos, a leading expert in prosthodontics, delved into the concept of using a single abutment, placed once, in dental implantology. Having used this technique since 2005, Dr. Pelekanos discussed its potential benefits and clinical reality, clarifying whether it’s a viable option for everyday practice.
The core idea of the "One Abutment, One Time" technique is to place the abutment at the time of implant surgery, eliminating the need for multiple disconnections over time. Dr. Pelekanos explained that the key factor in its success is the connection type—specifically, a stable internal connection. While the protocol isn’t universally applicable to every implant system, it has shown promising results when used with certain bone-level implants.
One major advantage highlighted was the reduction in bone loss. Studies indicate that frequent abutment disconnections can contribute to bone resorption. By using a single, stable abutment, the potential for bone stability and soft tissue health is improved, as the abutment helps shape the emergence profile of the implant.
Dr. Pelekanos also presented various cases where the technique was applied successfully, including immediate and delayed implant placements, as well as aesthetic zone treatments. He emphasized the versatility of the technique, showing that it can be used in a variety of scenarios, provided the implant is placed at the correct depth. Importantly, he noted that the technique is especially beneficial for cases involving connective tissue grafts or contour augmentation, as it helps stabilize soft tissues during the healing process.
In conclusion, Dr. Pelekanos confirmed that while challenges such as cementing and the necessity of compatible implant systems exist, the "One Abutment, One Time" technique offers a solid solution for enhancing the longevity and aesthetics of dental implants. For clinicians willing to adapt their practices, this approach can be a game-changer in implantology.
