Introduction
The rehabilitation of severely atrophic edentulous maxillae using zygomatic implants (ZIs) is a significant advancement in oral surgery. The recent systematic review titled "Evaluation of surgical techniques in survival rate and complications of zygomatic implants for the rehabilitation of the atrophic edentulous maxilla: a systematic review" provides critical insights into the survival rates and complications associated with two primary surgical techniques: the Original Surgical Technique (OST) and the Anatomy-Guided Approach (AGA).
Understanding the Techniques
The OST, rooted in the classic Brånemark approach, involves a two-stage procedure with implants placed in the zygomatic bone through the maxillary sinus. This method has evolved over the years, incorporating various modifications to enhance anatomical and prosthetic outcomes.
Conversely, the AGA, or Zygoma Anatomy-Guided Approach, focuses on tailoring the implant path to the patient's unique anatomical structure, potentially reducing complications by avoiding the sinus cavity.
Key Findings from the Review
- Survival Rates: Both OST and AGA demonstrated high survival rates, ranging from 90.3% to 100% for OST and 90.4% to 100% for AGA. This suggests that both techniques are viable for long-term implant success.
- Complications: The review highlights that while both techniques have associated complications, the AGA shows a reduced incidence of sinusitis and soft tissue infections compared to OST. Specifically, sinusitis was reported at 9.53% for OST and 4.39% for AGA.
- Loading Protocols: Immediate loading is more prevalent in AGA (89.6%) compared to OST (22.3%), indicating a shift towards quicker rehabilitation in recent practices.
Implications for Practitioners
For practitioners, these findings emphasize the importance of selecting a surgical approach based on individual patient anatomy and the specific clinical scenario. The AGA may offer advantages in reducing complications and enabling immediate loading, which can be particularly beneficial for patient satisfaction and recovery.
Furthermore, understanding the nuances of each technique, including potential complications and their management, is crucial for improving patient outcomes. Practitioners are encouraged to consider these findings in their clinical decision-making and to remain updated with ongoing research in this field.
Encouragement for Further Research
While the review provides substantial evidence supporting the efficacy of both techniques, it also highlights the need for further research to refine these approaches and explore new methodologies. Practitioners are encouraged to contribute to the body of knowledge through clinical trials and case studies that could provide deeper insights into optimizing zygomatic implant procedures.
