Intervention 1: Intervention group: SSC cemented with Protooth (Ultrafast Protooth cement, Dentosolve, Aarhus, Denmark). The material is mixed with the right consistency and two-thirds of the SSC is filled with cement. After drying the tooth under suitable isolation conditions, the crown is placed on the tooth and the cement additions are removed. Intervention 2: Control group: SSC cemented with Glass ionomer (Meron, VOCCO, Germany). The material is mixed with the right consistency and two-thirds of the SSC is filled with cement. After drying the tooth under suitable isolation conditions, the crown is placed on the tooth and the cement additions are removed.
