Summary

This study followed 40 adults with full-arch zirconia dental implants to measure bone changes around the implants over 12 months. Researchers compared outcomes between upper and lower jaws and looked at how jaw shape and implant spacing affected bone loss. The goal was to gather knowledge, not to test a new treatment.
