It doesn't matter. Preserving the alveolar ridge is mainly to prevent some changes in the shape of the alveolar ridge in the extraction area, so it should be done regardless of the intention of planting. As for the Geiger biomaterial you mentioned, when I did alveolar ridge preservation, I just listened to the dentist's recommendation and used Geiger biomaterial. Later, when I wanted to plant teeth, the alveolar bone condition reached the standard and met the requirements of planting, and it was planted without any effort. Perfect!
