•Suituable probands do not have any known allergies against the materials used (astringent, anesthetic, impression material).
•The PSI (periodontal screening index) is 2 or less (= no periodontal disease, a little calculus in the lower front at most).
•Both premolars in the 1st and 2nd quadrant as well as the adjacent teeth are present.
•The premolars and the adjacent teeth are either healthy and untreated or perfectly restored where the complete restoration margins are at least 1 mm above the gingiva; crowns were excluded.

•All probands, who do not fulfill the criteria for inclusion
•Probands, where a short-term restoration was impossible or where the complete healing before the end of the intervention phase of the study was not guaranteed
•Probands with inlays, onlays, or partial crowns at teeth Nos. 3 – 6 in the maxilla with margins of less than 1 mm above the gingiva
•Probands with crowns at teeth Nos. 3 – 6 in the maxilla with equigingival or subgingival margins
