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

Abstract

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. This systematic review aims to determine the presence of complications during maxillary sinus floor augmentation procedures using CAD-CAM surgical templates. 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. 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. 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.
