简要总结
While early implant placement with guided bone regeneration (GBR) offers advantages, the desire for reduced treatment time and fewer surgical steps continues to drive the exploration of alternative approaches. In this context, the recent introduction of vestibular socket therapy (VST) presents an intriguing option. VST utilizes a minimally invasive tunnel access technique through the vestibular area to perform socket augmentation for immediate implant placement in compromised extraction sockets .
详细描述
The concept of immediate implant placement has been around for a while. Professor Wilfried Schulte conducted the first study on this technique in 1978, Extensive studies conducted over the past 40 years have demonstrated that immediate implant placement is a safe and effective method for restoring teeth that are badly destructed.
While immediate implant placement has been shown as a viable option, new studies using advanced imaging techniques (cone beam CT scans) reveal limitations in the front upper jaw (anterior maxilla).
Thin Bone Walls: These scans show that a thick bone wall, ideal for implant stability, is uncommon in this area. Only about 5% of patients have a thick wall (>1mm) in the central incisor region.
Facial Bone Defects: Another recent study found that over half (52%) of implant sites in the central incisor area have a missing facial bone wall (defect).
These findings highlight the main concerns with immediate implants in the front upper jaw:
