“…A statistically significant difference was established concerning the implant stability quotient throughout this study period. The results of this study are in accordance with similar results demonstrated by Elnebairy et al [ 23 ] The RVG evaluation demonstrated mean mesial bone resorption of 1.22±0.16mm and mean distal bone resorption of 1.14 ± 0.13 mm at the end of the 6th-month postoperative period. The present data agrees with a study conducted by Crespi et al [ 24 ] who demonstrated that after a 24-month follow-up, mean mesial and distal bone loss was 1.16±0.32mm and1.17±0.41mm, respectively.…”

Our study aimed to evaluate the effectiveness of the bone ring technique for ridge augmentation using Demineralized Freeze – Dried Bone Allograft block in Siebert’s class II/class III defects along with simultaneous implant placement. A total of 15 partially edentulous patients (16 surgical sites) with Siebert's class II and/or class III defects in the anterior region of both jaws requiring ridge augmentation along with implant placement were selected. Starting from the first stage, surgery (Ridge augmentation+ implant placement) was done in the first month. Then, with continuous follow-ups and radiographic assessment, after 6 months of 2nd stage surgery was done, the implant was loaded with the final restoration. Significant results were revealed with all the parameters other than keratinized gingival and peri-implant mucosa thickness. With the mean bone resorption of 1.22 mm and 1.17 mm at the mesial and distal site at a 6-month interval, the success rate of the bone ring technique was 93.75%. The allograft bone ring technique showed a favorable outcome for the reconstruction of large vertical defects.

“…However, our results are less than Janyaphadungpong et al 38 evaluated implant stability in simultaneous GBR in the posterior mandible and found mean ISQ values of 72.55 ± 3.10 and 76.20 ± 2.68 at two and three months, respectively. Furthermore, the implant stability in our study in group II showed comparable results to Elnebairy et al 39 who conducted a randomized clinical trial to evaluate allograft bone rings around IIP in the aesthetic zone and showed that the mean ISQ value for the allograft ring was 58.0 ± 1.5 immediately after surgery and 68.0 ± 1.4 after 6 months post-surgery. Also, a study published by Pallavi et al 40 used allograft BRT with IIP in the anterior region and showed the mean ISQ score at the time of surgery was 58 ±1.62, and at 6 months, 69 ±1.59.…”

“…Sample Size: Sample size calculation was based on G*power version 3.0.10 to calculate sample size based on the effect size of 1.34, 2-tailed test, α error =0.05, and power 80.0% then total sample size will be 7 cases at least in each group. 26 Methods: The patients were randomly and equally divided into two groups: Group I (control group): involved 7 patients where a titanium mesh-guided bone regeneration was used for ridge augmentation with simultaneous immediate implant placement. Group II (study group): involved 7 patients where an allogeneic bone ring was used for ridge augmentation with simultaneous immediate implant placement.…”

Objective: To assess ridge augmentation with an allograft bone ring versus GBR with titanium mesh, and immediate implant placement (IIP) in the maxillary esthetic zone. Materials and Methods: The 12 patients with 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 post-operative clinical examinations each day for the first week, then once a month for the next six months. Results: : At 6 months postsurgery, all cases in the control group healed well and showed relative bone gain (7.09±1.56mm^2), and even though four of them had wound dehiscence, only one of them completely healed during the follow-up period. In the study group, at 6 months following surgery, the relative bone gain was (2.76±1.06 ^2). All cases healed well, with no dehiscence or infection except for two cases of allograft ring failure due to early exposure within two weeks after surgery which did not respond to local measures or disinfected applications. Conclusions: Those certain two simultaneous procedures achieved promising and advantageous results; therefore they could be used as an alternative treatment to other graft techniques, in particular for defective sockets in the maxillary aesthetic region.

“…Symphysis area offers a sufficient amount of cortico-cancellous autogenous bone in addition to its easy access under local anesthesia. For achieving accuracy in selection of implant length, diameter, exact site, angulation without endangering the nearby vital structures and increase success rate with less operative time and less operator skill by using preoperative computerized virtual planning of donor and recipient surgical sites and fabrication of surgical guided stent (15) . Statistical analysis of CBCT images linear measurements in our study revealed that, there was a significant decrease in 3D dimensions of vertical bone height from immediate to 6 months with high percentage of bone resorption.…”

Purpose: to evaluate clinical and radiographic outcome of bone ring grafting technique with immediate implant placement in fresh extraction socket in mandibular posterior area. Patients and methods: Clinical study was conducted on six patients, suffer from deficiency in vertical height at posterior mandibular area. Extraction and immediate implant reconstruction with symphyseal bone grafting in one-stage procedure. All steps of harvesting by trephine bur, implant osteotomy and placement within the socket were guided by computerized surgical stent for donor and recipient sites. Platelet Rich Fibrin (PRF) membrane was prepared to cover the implant at suture line. Patients were followed up clinically and radiographically by Cone Beam Computed Tomography (CBCT) at immediate,3 and 6 months postoperatively to evaluate the implant site and vertical bone height changes. Results: One successful case out of six showed excellent soft tissue healing with implant stability. Clinically one case showed sever infection at 2 weeks postoperatively with looseness of implant. Dehiscence and pain were found in 83.3% of the cases. Four cases had mild pain and one case suffered from severe pain, edema was mild in the majority of patients, numbness was found in 4 cases with 66.7%. CBCT results showed significant decrease in 3D dimensions of vertical bone height from immediate postoperative to 6 months with percentage of resorption (Buccally37.49±12.14, Lingually36.12±12.04, Mesially 39.55±15.05 and Distally10.92±0.76). Conclusion: From our study, Bone ring augmentation technique for fresh defective sockets with immediate implants at posterior mandibular area achieved low success rate, long procedure time and donor site morbidity.
