•Subjects with the treatment need for one deeply destroyed front tooth or premolar with a proximal distance = 7 mm will be included. Decoronated teeth with a supra-gingival amount of hard tissue after crown preparation of less than 2 mm in height will be receiving a surgical crown lengthening in order to ensure sufficient retention.

•Minors or persons incapable of contracting; pregnant women; alcohol or drug addicts;patients with an existing infectious disease as hepatitis or HIV/AIDS; patients where an existing general disease means a contraindication for an implantation; patients with a severe diabetes; patients with a periodontally harmed abutment tooth (degree of tooth mobility > 1 and/or a pocket depth > 3.5 mm); patients with insufficient oral hygiene (PI > 1, BOP positive on more than 20% of all teeth);patients, who would be in a conflict of interests due to their participation in another study; patients, who did participate in another clinical study within one month prior to the beginning of the study.
