Study Arms:
- Straumann BoneCeramic (Type: ACTIVE_COMPARATOR): In the test group, the subjects will receive the Bone Graft Material Straumann BoneCeramic in combination with a collagen membrane for preservation of the alveolar ridge after tooth extraction.
- Freeze Dried Allograft Bone (Type: ACTIVE_COMPARATOR): In the control group, the subjects will receive Bone Graft Material Freeze Dried Allograft Bone in combination with a collagen membrane for preservation of the alveolar ridge after tooth extraction.

Based on this trial design, predict the completion outcome and termination type (if applicable).
