Both study groups showed a statistically significant increase in bone width at 6 months, with the highest increase observed in group A2 (ABG + rhBMP-2), with the highest increase observed in group A2 (ABG + rhBMP-2).
Abstract
The goal of this study was to evaluate the efficacy of autogenous bone grafts with and without recombinant human bone morphogenetic protein-2 for rehabilitation of narrow alveolar ridge width by dental implants. Twelve patients (2 males and 10 females), ranging from 36 to 60 years and a mean age of 47.08 years, were divided into two study groups. One received autogenous bone graft (A1) and the other group autogenous bone graft with rhBMP-2 using a collagen membrane (A2). All patients were clinically evaluated and received a CBCT for an accurate measurement of the alveolar ridge width, height, and after six months postoperatively. The mean difference in primary and secondary alveolar bone width (after 6 months) in group A1 was 4.14 mm, with a statistically significant difference (p < 0.05). Also, the mean difference in primary and secondary (after 6 months) alveolar bone width in group A2 was 5.14 mm, with a significant difference between them (P-value 0.00). The addition of rhBMP-2 increased the extent of bone width regeneration compared with the autogenous bone graft used alone. Both study groups showed a statistically significant increase in bone width at 6 months, with the highest increase observed in group A2 (ABG + rhBMP-2).
This study aimed to compare the clinical performance of autogenous bone blocks with customized and noncustomized bovine bone blocks for horizontal alveolar ridge augmentation. Forty‐eight participants with deficient alveolar ridges were divided into threegroups (n = 16): Group I (autogenous bone graft), Group II (noncustomized bovine bone block), and Group III (customized bovine bone block). Graft success, postsurgical complications, bone formation, and resorption rates were recorded and analyzed after 6 months. Patient satisfaction and postoperative pain were assessed using a visual analog scale. A total of 39 bone blocks were integrated successfully. Survival rates for Groups I, II, and III were 100% (95% CI: 79.4%–100%), 75.0% (95% CI: 47.6%–92.7%), and 68.8% (95% CI: 41.3%–89.0%), respectively (p = 0.07). Dehiscence, screw exposure, and partial bone loss were the most common postoperative complications. Bone formation and resorption did not differ significantly between groups (p = 0.61 and p = 0.12, respectively). Group I experienced significantly higher pain from day 3 to day 7 compared to other groups (p < 0.001), with peak pain on day 6 (5.75 ± 1.12), while Groups II and III reported peak pain on day 3 (3.06 ± 0.92 and 3.44 ± 0.81, respectively). By day 10, pain scores had decreased substantially in all groups, with Group III reporting the lowest scores (0.31 ± 0.48, p = 0.003). Patient satisfaction was highest in Group III (91%). Within the limitations of this prospective comparative study, onlay grafting with bovine bone blocks demonstrated clinically acceptable outcomes for horizontal ridge augmentation, with resorption rates comparable to autogenous grafts. However, the observed survival differences did not reach statistical significance, and the wide confidence intervals reflect the limited sample size, suggesting that clinically meaningful differences cannot be excluded. Customized bovine bone blocks showed similar clinical performance to noncustomized blocks with higher patient satisfaction. Larger randomized controlled trials with longer follow‐up are warranted to confirm these findings.

OBJECTIVE
Aim: To compare the quantity and quality of surrounding soft tissues in patients after segmental mandibular defect reconstruction (SMDR) with bone grafts, before and after placement of implant-supported dental prostheses (ISDPs).
PATIENTS AND METHODS
Materials and Methods: A total of 74 patients were included and divided into main (MG) and control (CG) groups. The MG consisted of patients after SMDR. The CG comprised 49 patients with a Kennedy Class II dental arch defect following tooth extraction. The width and area of attached gingiva (AG) were assessed before and after ISDP placement using intraoral scanning.
RESULTS
Results: After ISDP placement, the mean buccal width of AG at the medial implant was 0.94±0.90 mm in the MG and 2.18±0.95 mm in the CG (p<0.01). In the distal buccal region, the median values were 0 (IQR: 0-1) mm and 1.7 (IQR: 1-6) mm, respectively (p<0.001). The mean lingual width at the medial implant was 1.11±0.99 mm in the MG and 2.24±0.97 mm in the CG, whereas at the distal implant the median values were 0 (IQR: 0-0.6) mm and 2.1 (IQR: 1.5-2.75) mm, respectively (p<0.001). The median area of AG was 63.3 (IQR: 38.9-100.45) mm² in the MG and 233.9 (IQR: 186.75-295.75) mm² in the CG (p<0.001).
CONCLUSION
Conclusions: Patients after SMDR and placement of ISDP are characterized by lower quality and reduced volume of AG compared to conventionally rehabilitated patients with ISDP. To improve the long-term prognosis of treatment, soft tissue augmentation may be recommended.
