In Kundrat v. State Dental Council and Examining Board, 67 Pa. Commw. 341, 447 A.2d 355 (Pa. Cmwlth. 1982) a dentist installed a ten-tooth bridge in a patient's mouth by affixing it to three remaining anterior teeth; the bridge failed. The Dental Board found, without the benefit of expert testimony about the standard of care for fashioning a bridge, that the respondent had committed dental malpractice. The Court held that expert testimony was not necessary in this circumstance, holding that the dentists on the board could "draw on their expertise" to reach this conclusion. Id. at 358. Kundrat is best explained as a gross malpractice case.
