B2 A AOM S N EWS Implant Tribune U.S. Edition | October 2020 JOMS: For jaw cancer patients, in-house 3-D printing allows quicker restoration of teeth In-house 3-D printing allows patients with malignant disease to more quickly receive immediate tooth restoration — treatment that had been regarded as low importance for these patients because of the severity of their disease, a new study found. The 3-D digital workflow eliminates the wait in providing replacement teeth using the conventional approach and is less costly, according to the study pub- lished in the August issue of the Journal of Oral and Maxillofacial Surgery, the official journal of the American Associa- tion of Oral and Maxillofacial Surgeons (AAOMS). For the study, 12 patients underwent virtual surgical planning (VSP) for a pro- cedure called free fibula maxillofacial reconstruction, which replaces bone and soft tissues in the face removed to treat cancer with bone and soft tissue from the patient’s leg. A dental prosthesis was created for each patient to be placed at reconstruction. For five patients, a den- tal laboratory made the prostheses. For the other patients, a surgeon designed the prostheses and 3-D printed them in- house. Four of the patients who received a prosthesis from the in-house 3-D print- ing had malignant tumors. Researchers found time and cost were less for developing the prostheses in- house than using a dental laboratory. Sending production of a prosthesis to dental laboratories leads to delays in the prosthesis being ready to give to the pa- tient soon after cancer surgery, the study notes. “Such a delay has limited the useful- ness of this treatment to benign condi- tions,” researchers wrote. “With point- Photo/Julia Freeman-Woolpert, freeimages.com For more information To learn more about 3-D printing, attend the ‘3D Printing and Virtual Surgical Planning in Maxillofa- cial Surgery – The pitfalls and the pearls’ session, to be held from 10:05 to 11:05 a.m. Thursday, Oct. 8, during the AAOMS virtual conference. of-care 3-D printing, we have fabricated a dental prosthesis within 24 hours of the VSP session, eliminating any additional waiting period before surgery.” For the in-house printing, the surgeon received digital files immediately after the VSP session. Within a day, the pros- thesis was 3-D printed. The in-house prostheses were prepared for surgery one to two weeks before a plate and mod- els from VSP arrived, so treatment was not delayed more than the standard du- ration for acquiring the plate and models from the vendor, according to the study. By comparison, the offsite dental labo- ratory needed an additional two weeks to create the prostheses. On average, the prostheses created at the offsite dental laboratory cost $617 compared to $8.34 for resin for the in-house 3-D prosthesis, the study notes. However, the research- ers cautioned that costs are associated with obtaining a 3-D printer and supplies (less than $3,000). The small study did not compare pros- thesis quality between the two settings. “As point-of-care 3-D printing becomes available to more surgeons, we anticipate this will become a viable solution for many patients,” researchers wrote.
