Accredited: A Culture of Safety
We hold ourselves to a higher standard than any practice in the community. In 2006, OSA became the first and only OMS office in Northern New England to meet the rigorous standards of the Joint Commission by achieving accredited status. Like hospitals, we welcome unannounced inspections every three years that ensure our facility meets critical standards in several aspects of patient care and organizational safety. Our most recent inspection in 2018 found no areas for improvement, a rare feat for any facility. In recognition of our dedication to our quality and safety standards, our practice received the Maine Medical Center Physician-Hospital Organization Specialty Care Award. No other OMS practice in Maine has yet received this high honor, or become accredited like OSA for office-based surgery.
Credentials Matter, Experience Counts
While many dentists call themselves “specialists” or “board certified”, these titles are often deceiving. Each doctor at OSA has completed a true ADA-recognized residency that required 6 years to complete. The board certification process for our doctors is the most rigorous in organized dentistry, and the gold standard of our profession. In an era where more oral surgeons treat only teeth and titanium (dental implants), OSA again sets a higher bar. We are a full scope OMS practice treating patients for a wide range of conditions in both office and hospital settings. These include dentoalveolar surgery (including wisdom teeth), dental and maxillofacial implants, pediatric oral surgery, orthognathic and reconstructive surgery, maxillofacial tumors, cleft lip and palate, major and minor bone grafting, snoring and sleep apnea, temporomandibular joint problems, and maxillofacial trauma.
