The Use of CAD-CAM Templates in Lateral Sinus Floor Augmentation Procedure: A Systematic Review.

INTRODUCTION:Maxillary sinus floor augmentation is a procedure known for its long-term success and predictable outcomes. However, the perforation of the Schneiderian membrane remains the most common complication associated with this procedure. OBJECTIVE:This systematic review aims to determine the presence of complications during maxillary sinus floor augmentation procedures using CAD-CAM surgical templates. MATERIAL AND METHODS:An electronic search was carried out in MEDLINE (via PubMed), Web of Science, and Scopus. A descriptive analysis of the data was performed. Studies that have performed lateral sinus floor augmentation were included in the inclusion criteria. The CAD-CAM surgical template design and the intraoperative complications were registered. RESULTS:A total of 13 studies were included. Seven were case reports, four were case series, and two were randomized clinical trials. A total of 94 lateral SFA procedures were included (84 using CADCAM templates and 10 without using templates). Three of the 84 maxillary sinus floor augmentation procedures using a CAD-CAM template presented intraoperative complications. CONCLUSIONS:Maxillary sinus floor augmentation performed by using CAD-CAM surgical templates could be related to low rates of complications, however, due to the heterogeneity of the articles included, more standardized studies are needed to confirm these outcomes.
