Abstract
Abstract
Objective: To evaluate the effect of hyaluronic acid mixed with biphasic calcium phosphate on bone healing around immediately placed implant in the posterior mandibular region.
Patients and Methods: This clinical study included 16 implants placed for 14 patients who were seeking for extraction of non-restorable mandibular posterior tooth and replacement with immediate implant. The patients were randomly and equally divided into two groups; extraction of the non-restorable tooth with immediate implant placement and the gap between the implant and socket walls was filled with BCP bone graft only in group I (control group) and with BCP bone graft mixed with HA in group II (study group) and The evaluation was done immediately (Tx), postoperatively at loading (T0), at 3&6 months after loading (T3&T6) respectively to assess implant stability, modified sulcus bleeding index, Peri-implant pocket depth, bone loss around the dental implant.
Results: The study included 7 females (50 %) and 7 males (50%). No statistically significant differences were recorded between both groups regarding age, sex (P=0.642, 0.451) and implant characters (length, width) (P=0.751,0.851) respectively. No statistically significant differences were found between both groups in implant stability (P=0.735, 0.722, 0.410), mSBI (P=0.662, 0.642, 0.448) PPD (P=0.278, 0.06, 0.120) and bone loss (P= 0.562, 0.492) at different time intervals of assessment.
Conclusion: The effect of HA with BCP bone graft was not superior on bone healing around immediately placed implant than BCP bone graft alone in posterior region of the mandible.
