I have used the zygomatic injectionto devitalize the first maxillary molar. It was repaired with alarge hand-carved porcelain crown to fill in the spaces on eitherside. The two maxillary bicuspids I devitalized with the infil-tration method horizontal injection. The central lateral andcuspid were anaesthetized by the horizontal injection, com-bined with the incisive injection to extract the two latter onaccount of their position. The central incisor I devitalized fora banded post crown. In the lower jaw I used the pterygo-mandibular injection, to prepare the second molar for an allmetal crown, to devitalize the first bicuspid for a banded postcrown, and the cuspid for a half crown with post. All thegrinding and most of the fitting was done under local anaes-thesia. Fig. 78 shows the case Fig. n. Crown and bridge case II, before treatment.
