Objective: The present study aimed to assess ridge augmentation with an allograft bone ring versus GBR with titaniummesh, and immediate implant placement (IIP) in the maxillary esthetic zone. Materials and Methods: The 12 patientswith 14 defective sockets were randomly divided into two groups: three females and four males in the control group(Titanium mesh-GBR), and three females and two males in the study group (Allograft bone ring). Patients had postoperativeclinical examinations each day for the first week, then once a month for the next six months. Results: : At 6months post-surgery, all cases in the control group healed well and showed relative bone gain (7.09±1.56mm^2), andeven though four of them had wound dehiscence, only one of them completely healed during the follow-up period. Inthe study group, at 6 months following surgery, the relative bone gain was (2.76±1.06^2). All cases healed well, with nodehiscence or infection. Except for two cases of allograft ring failure due to early exposure within two weeks aftersurgery, which didn’t respond to local measures or disinfected applications. Conclusions: Those certain twosimultaneous procedures achieved promising and advantageous results, therefore they could be used as an alternativetreatment to other graft techniques, in particular for defective sockets in the maxillary aesthetic region.
