Dr. Donald I Rothenberg has been doing dental implants in Boston area since 1986 and was among the graduates of the first university based dental implant continuing education program in 1987 when he completed the Harvard University Implant Study program. Then he started his practice in the Boston area. Dr. Rothenberg and his staff perform both phases of implant dentistry, surgery and reconstruction , in Marblehead, Massachusetts. In addition to implant surgical placement (dental implants), he is able to design, create, and place the crown and bridge work that goes on top of dental implants. Sedation dentistry offers many benefits to dental patients. The traditional use of this treatment method of course is for addressing the interests of those who have histories of "dental anxiety" (which probably applies to all of us, at one time or other).
