Cases where insufficient bone volume is observed at the implant site during implant treatment bone loss, dental implant, bone augmentation, bone filler material
Conditions
Interventions
Patients will be divided into two groups based on the type of bone filling material, and the effects of each bone filling material will be compared between the groups.
