Aim: The aim of this study were to evaluate dental implant stability and marginal bone level after immediate implant placement with simultaneous grafting of the peri-implant gap with either xenograft or alloplastic bone graft.
Materials and methods: Twenty two patients (18 females and 4 males) received 36 immediate dental implants inserted in maxillary fresh extraction sockets, was randomly assigned into two groups with peri-implant gap augmentation with either xenograft (Group A) or alloplastic bone graft (Group B). Implant stability measurements were measured by Periotest M device and marginal bone levels was measured with the aid of othropantomogram radiography, both measurements on immediate postoperative (Baseline) and after a period of six months.
Results: The percentage of change of secondary stability between the two groups was 191.8% reduction of Periotest values scores in group A and 175.7% reduction of scores in group B with no significant difference between them (p??0.05), marginal bone loss in group A was 1.5 mm mesialy and 1.57 mm distally, and for group B the marginal bone loss was 1.71 mm mesialy and 1.47 mm distally with no statistical significant difference between the two groups (p??0.05).
Conclusion: The findings of this study indicated no significant statistical differences in implant stability and marginal bone levels between immediate implants grafted with either type of bone substitutes.
