[Two-stage replantation of molars and premolars in acute and exacerbated chronic periodontitis].

The author reports about the clinical and X-ray study of 25 patients who were replanted 25 teeth in two stages -- 12 teeth of the upper and 13 of the lower jaw-during acute and exacerbated periodontitis. Lyophilized spongiosis chips were deposited in the alveoli before the replantation of 5 teeth. During the first stage, the extracted tooth is mechanically cleaned, washed with hudrogen peroxide and alcohol and then preserved in a solution of penicillin and physiological salt solution in the refrigerator at a temperature from +2 to +5 degrees C. During the second stage, the tooth is taken from the refrigerator after two to five 24-hours, obturated and replanted. The results allowed the conclusion that the method could be applied only in exceptional cases. The use of lyophilized spongiosis chips in replantation of teeth should be studied thoroughly in the future, presuming that it will contribute to the longer-term survival of replanted tooth.
