Implant placement (BLX implant system, Straumann, Basel, Switzerland)
Implants are placed after a healing period of 4 months (delayed implant placement, control group) or immediately after tooth extraction and ridge preservation (immediate implant placement, test group).
Ridge preservation (Bio-Oss Collagen 250 mg, Geistlich Pharma AG, Wolhusen, Switserland)
Ridge preservation is performed by inserting a collagen-enriched DBBM (Bio-Oss Collagen 250 mg, Geistlich Pharma AG, Wolhusen, Switserland) in the empty extraction socket (delayed implant placement, control group) or by filling the gap between the implant and buccal bone wall (immediate implant placement, test group).
Socket seal (Mucograft Seal, Geistlich Pharma AG, Wolhusen, Switserland)
The occlusal aspect of the grafted socket in the delayed implant placement/control group is closed with a collagen matrix.
