SML

SML, historically known as Space Maintainers Laboratories, is a long-established dental laboratory company focused on orthodontic, orthopedic, pediatric, and sleep-related oral appliances. Founded in 1957, the company manufactures custom dental devices for dentists and orthodontists, including space maintainers, expanders, retainers, mouthguards, splints, and oral appliances for snoring and obstructive sleep apnea. SML operates as a commercial dental lab rather than a drug-development biotech company, with services spanning appliance fabrication, digital diagnostics, and metal-printing-enabled dental production. The business serves dental professionals across multiple geographies from its Chatsworth, California headquarters and affiliated regional labs.
