Abstract:

Objectives: Navy Dentistry’s mission is maintaining a high state of operational dental readiness to reduce avoidable dental emergencies for deployed sailors and marines. With the development of computer-aided design and computer-aided manufacturing (CAD/CAM), dentists can provide high quality esthetic treatment to patients in a single setting making it a potential tool to achieve high dental readiness while providing ideal treatment. The objective of this study is to provide a 2-year longitudinal follow-up on our previously reported results that compared placement rates by Navy Dentists of digitally fabricated in-office ceramic restorations to traditional laboratory fabricated restorations.

Methods: Our previous study queried Navy dental treatment databases for procedure codes indicative of cuspal coverage restorations from January 2008 until August 2015. Additional queries obtained treatment data from August 2015 to July 2017. Procedure codes specific to CAD/CAM restorations were available for query beginning October 2011. Monthly restoration totals were calculated for each procedural code category and converted into percentages representing their contribution to the total number of restorations placed between January 2008 and July 2017.

Results: In January 2008, Porcelain-Fused-to-Metal (PFM) and metal crowns represented 22.0% and 11.3%, respectively, of all cuspal coverage restorations. Since CAD/CAM data collection began in 2011, CAD/CAM restorations saw a significant annual increase of 2.5% with a reported utilization percentage of 19.9% in 2017. In contrast, PFM usage significantly decreased 2.2% annually with a final utilization percentage of 7.0% in 2017. Metal crowns did not report a significant change. (Figure 1)

Conclusions: Results indicate an agreement with our 2015 utilization model that CAD/CAM usage by Navy dentists would continue to increase. Digital dental technology has the potential to become the standard of care in a military health care environment where the focus is on maintaining a high state of dental readiness even when access to patients is hampered by high operational tempo.
