Abstract Objective: The aim of this study is to evaluate the clinical outcome of the custom healing abutment in maintaining emergence profile at immediate dental implant placement in mandibular posterior region. Materials and Methods: Fourteen patients were selected for replacement of a single non restorable mandibular premolar or molar tooth (posterior region) by immediate dental implant. The gaps around implant were grafted with bovine bone mineral, all implants were connected with custom healing abutment. All implant were evaluated clinically at implant placement time (T0), 3th (T1) and 6th months (T2) after surgery regarding resonance frequency analysis (RFA), peri-implant pocket depth (PPD), modified sulcus bleeding index (mSBI), and pink esthetic score (PES). Marginal bone loss was evaluated radiographically at implant placement time (T0) and 6th months (T2) after surgery. Result: During the follow up period, no implant was lost and all patients showed favorable clinical and radiographic finding. RFA evaluation using Osstell device showed that all implant were well osseointegrated and stable. There was no statistically significant difference in PPD, and mSBI (P-value 0.060, and 0.063 respectively). There was a statistically significant increase in PES, and marginal bone loss (P-value < 0.001). Conclusion: Within the limitation of the present study, the results of this study suggest that customized healing abutments for immediate implants placed into posterior sockets can facilitate closure of large sockets, stabilize the gingival architecture, and provide a custom seal over the surgical site to retain graft particles. |
