Abstract

Objectives: the aim of this study was to compare the difference in marginal bone loss around the splinted and non-splinted implants supported on OT bridge system in full arch implant mandibular restoration using the All-On -Four concept. Materials and methods: This study was conducted on 12 completely edentulous patients having 48 implants. All patients were treated with a mandibular implant supported fixed restoration. Four implants were placed interforaminally for each patient and restored with immediately loaded restoration following the All-On-Four concept. Comparison was made between the splinted implants and non-splinted implants of immediately loaded temporary conversion prosthesis using OT bridge system regarding the marginal bone loss (MBL) using digital periapical radiograph at base line and after 3 months. Results: The marginal bone loss around both groups splinted and non-splinted implants after 3 months of immediate loading was similar with no statistically significant difference. Conclusion: Both techniques are considered as reliable methods for immediate loading of a full arch screw retained implant restoration with no preference of one approach regarding marginal bone loss around implants.
