Tooth extraction is followed by marked alterations of the tissue volume. The resorption process of at least the surrounding mucosa can be altered by using immediate implant placement and additional features such as immediate provisional crown, platform switching and grafting the gap between implant and buccal bone plate. The support of the gingival margin with a provisional crown led to an increase of buccal gingival tissue. Teeth scheduled for extraction will be used to study the effect of a customized healing abutment. The following groups will be randomly assigned: Control: A commercially available healing abutment will be screwed on top of the implant and a collagen sponge will be used to protect the graft. Test: A customized PEEK abutment mimicking the subgingival emergence of the extracted tooth will be screw retained on top of the implant to seal the extraction site.
