The use of extreme magnification in fixed prosthodontics.

The surgical operating microscope was introduced in the early 1920s, but it was largely ignored until 1950, when it was reintroduced by Richard A. Perritt for use in microsurgical operations in opthamology.1 The magnification and illumination provided by the microscope has resulted in its acceptance as an essential part of the surgical armamentarium. Microsurgical techniques gained widespread acceptance, primarily in otolaryngology, ophthalmology, neurology, and urology, and they play a critical role in surgery to reattach severed extremities.2-8
