Fears raised over 3D printing in dental clinics
Equipment has potential to emit ultra-fine particles and volatile organic compounds.
Safety concerns are emerging over the increased use of 3D printing in dental clinics.
The rapid integration of 3D printing into dental practice has transformed workflows by enabling the in-house fabrication of appliances, dental models and surgical guides. Many clinics now routinely have 3D printers on site, reducing dependence on labs – and costs – while improving turnaround times.
“However, alongside these benefits, safety concerns are emerging,” said Dr Prasad Nalabothu, a research scientist at the Oral and Maxillofacial Surgery Clinic, University Hospital Basel, in a new British Dental Journal report.
“Research has demonstrated that desktop 3D printers have the potential to emit ultrafine particles (UFPs) and volatile organic compounds (VOCs) during operation, which have consequences for air quality and occupational health.”
Recent data from NHS trusts demonstrate an expansion in the adoption of 3D printing, but approaches to regulation and safety remain inconsistent, added said Dr Nalabothu.
“While some organisations may adhere to ISO 13485, MDR (Medical Devices Regulation), or MHRA (Medicines and Healthcare Products Regulatory Agency) processes, numerous reports indicate the absence of specific standards being implemented,” he said.
Dr Nalabothu said that the adoption of practical measures such as enclosed printers, adequate ventilation and local extraction has the potential to reduce the associated risks.
“However,” he added, “it must be noted that without more robust and comprehensive guidance, the implementation of such measures may remain inconsistent and uneven. A coordinated approach from the General Dental Council, dental associations, and occupational health authorities could provide much-needed direction.
“It is imperative that future research also incorporates the consideration of emissions, material safety, and environmental impact, thereby ensuring that innovation is embraced without compromising health.”
