“…In the present study, serum from diabetic rabbits induced osteoblast dysfunction after seeding cells alongside titanium implants for 7 days. These findings are in accordance with several experimental studies that revealed an impaired bone healing response to implant placement in diabetic animals compared to non-diabetic controls [26,27]. Several mechanisms have been proposed, including impaired tissue integration, increased foreign body reaction, and oxidative environment surrounding the implants [28,29], but none have been definitively proven.…”
