OBJECTIVES:: our goal was to map the materials requested for orthognathic surgery across Brazil providing an overview of current practices and their possible economic impact for the private health care system (PHS). METHODS:: Anonymized demographic and clinical real-world data (RWD) were retrieved from Auditron® (Evidencias-Kantar Health database of claims) for all orthognathic surgeries performed between 2013-2016. We included only cases of maxillomandibular corrections, excluding surgeries for cyst removal, trauma and any other indications. The lists of essential (fixation plates and screws) and supplementary materials and their distribution were also extracted. Costs were calculated using SIMPRO values. RESULTS:: over 700 surgery requests were initially retrieved and 271 regarding 266 patients (5 patients had more than one claim) fulfilled our inclusion criteria. Surgeries were performed in 99 males and 167 females; with an age range of 14-63 years. Requests came from 33 health care providers from all Brazilian regions: North (3); Central-West (24), Northeast (67), South (88) and Southeast (84). We found a wide variability in the bone synthesis materials’ models and brands. Supplementary materials included (n=number of requests; upc=units requested per case; unitary cost in Brazilian Reals): microdissection needle - Colorado needle or similar (n=114; upc=1; R$7,470.00 to R$12,250.00); ultrasonic tools - Piezosurgery or similar (n=92; upc=1 to 5; R$14,990.00); intermaxillary fixation screws (n=135; upc= 4 to 8; R$1,471.68); “virtual" surgical splints (n=28; upc=1 to 2; R$12,000.00); bone substitutes in bloc, grains or paste (n=117, upc=not applicable, R$ 1,200.00 to R$18,300.00); re-absorbable membrane (n=42,upc=1 to 4, R$534.00 to R$3,400.00) and hemostatic agents (n=87, upc=1 to 4, R$1,500.00 to R$19,100.00). CONCLUSIONS:: These variations in brands, models, quantities and costs of requested materials suggest a lack of uniformity among conducts that could have an economic impact for PHS. Evidence-based specialty guidelines could help mitigate these variations, providing better quality-of-care for patients and saving resources for PHS.
