Reconstruction failure / chip fractures (12 months) · Patients with all-ceramic implant FDP reconstructions; parallel group, 12-month
1 finding from 1 review
None of the 25 reconstructions had failed; significantly more chip fractures in the Denzir group, but as none required repair this outcome was deemed not clinically significant (narrative)
