Introduction: Immediate implant placement benefits include saving time decreases the cost, and eliminating a second surgery. However, when the jumping gap between the implant and the socket is larger than 2mm bone graft is required to avoid failure of the implant. Customized healing abutment can help in increasing the bone density and allow soft and hard tissue healing with no bone grafting leading to the success of the implant.
Objectives: This study was to assess clinically and radio-graphically the effect of the customized healing abutment on peri-implant bone density, crestal bone loss, and osseointegration after graft less immediate implant placement in the mandibular molar region.
Materials and Methods: A prospective study was conducted out on 8 cases (20-40 years old). Implants were placed immediately after extraction of an unrestorable mandibular molar without grafting, and a customized healing abutment was fabricated. Patients were assessed both clinically and radio-graphically for 6 months to assess pain, edema, probing depth, per implant bone density, and marginal bone level.
Results: Regarding clinical follow-up, all cases reported pain and edema which subsided within the first week, while the mean probing depth showed insignificant difference throughout the study period ranging from 2 to 3 mm. The radiographic follow-up showed a significant increase in mean peri-implant bone density, whereas the mean marginal bone level was 0.32 ± 0.23 mm at 6 months postoperatively.
Conclusions:customized healing abutment proved successful in increasing the per-implant bone density and achieving osseointegration with immediate implants placed graftlessly in the mandibular molar region
