Summary

In this study, participants with one lower first molar that require removal and replacement using dental implants will be enrolled. The implant will be inserted 12-16 weeks after tooth extraction and restored either immediately with an artificial tooth (fixed implant crown) in 50% of the cases or 4 weeks later in the remainder 50%. Immediate and early loading will be compared and the investigators expect no difference in terms of implant success and health of the tissue around the implant.
