Marginal Bone Loss around Early Loaded SL Active Implants with Different Retention Means and Antagonist Arches: Clinical Comparative Study
Aim: The objective of the present study was to estimate the marginal bone loss (MBL) around early loaded SLActive implants during the first 3 months after loading of the prosthesis with cemented and screw retention means and different antagonist arches using cone beam computed tomography (CBCT).
Materials and Methods: Twelve patients (10 females and 2 males) received 40 SLActive implants inserted with flap and flapless approach and underwent early loading protocol after 8 weeks of healing time, of which 28 DI with screw retention mean. While, 12 DI with cemented retention. Marginal bone loss (MBL) was measured directly by CBCT at the same day of operation and 3 months after loading. Statistical analyses was carried out to study MBL between different retention means and antagonist arches.
Results: No implant was lost during the study follow up appointments with survival rate of 100%. MBL between the cemented and screw retention means showed a statistically no significant difference (p˃0.05). On the other hand, MBL significantly decreased (p˂0.05) with prosthesis opposing arch.
Conclusion: The findings of this study indicated no differences in MBL between different retention means that may be related to the enhanced osseointegration characteristics of hydrophilic SLActive implant surface and improved bone formation during short period of time.
