The Roxolid® material is designed to reduce the invasiveness of procedures with smaller implant diameters thanks to improved mechanical and biological properties. Predictability can be further improved by enhancing the bone formation and stability around the implant. SLActive® supports less invasive procedures with narrower implants in the anterior and premolar regions by enhancing the bone stability and the success rate as shown in a randomized controlled clinical study.10
Bone defects such as bone dehiscences, fenestrations or coronal circumferential defects can compromise the predictability of osseointegration. SLActive® promotes the production of significantly greater and more mature bone than hydrophobic surfaces, and it increases new bone height, bone fill and BIC.4, 11, 12
The timing of implant placement post-extraction in the esthetic zone is considered to be an important success factor. Ridge changes after tooth extraction occur from bone resorption and often result in a crater-like bone defect on the facial aspect of the extraction site. SLActive® demonstrates long-term stability of peri-implant hard and soft tissues after 6 years with highly esthetic outcomes in early implant placement.13, 14
During the healing phase, a prosthetic restoration can be placed. However, uncontrolled loading on a healing implant increases the risk of early failures. SLActive® has shown more predictability in early loading protocols. Immediate and early loading with the SLActive® surface yield excellent long-term results with survival and success rates of 96.8 % after 5 years, even in poor bone quality.15
