摘要： A dual dental matrix band retainer for use in dentistry comprising a first matrix band retainer which is connected to a second matrix band retainer. Each matrix band retainer is provided with a matrix band which is looped around a different posterior tooth in the same quadrant of a patient's mouth. Each matrix band retainer can be operated independently and separably of each other which allows for the dentist to restore two posterior teeth simultaneously. As a result, the time required for the dentist to restore both posterior teeth is greatly diminished improving the work productivity of the dentist while maximizing the comfort to the patient.
