A 75-year-old female patient visited our dental clinic reporting a loose crown on tooth #26. The tooth had been endodontically treated in the past and had a carbon-fibre post. The tooth had been prosthetically restored and presented severe caries without early apical destruction or alteration. The patient had previously had a gold crown on the tooth.

Fig. 1: Tooth #26 presented bent and diverging roots. The tooth was severely decayed.

Fig. 2: The roots were separated to the correct depth. The tooth was divided into three parts to facilitate extraction.

Fig. 3: The tooth was luxated with Luxator P4 (dual edge, lilac).

Fig. 4: Elevation of the palatal root.

Fig. 5: Luxation of the mesiobuccal root.

Fig. 6: Continued luxation with Luxator P1 (straight blade, dark green).

Fig. 7: Palatal root removed. Bone socket after removal of the palatal root.

Fig. 8: The mesiobuccal root was luxated.

Fig. 9: The mesiobuccal root was removed.

Fig. 10: All roots were extracted separately.

The new, very thin Luxator P-series periotome made it possible to perform an atraumatic extraction with minimal loss of bone. Luxator P4, with its extremely sharp dual-edge blade, was used, followed by Luxator P1, once some space was created. Although the blades of these sophisticated instruments are reinforced with a titanium coating, they should only be used to cut the periodontal ligament and never to elevate the tooth. After sectioning the tooth and gently cutting the periodontal ligament, each root could easily be taken out with the help of diamond tweezers.
