Advances in Guided Bone Regeneration (GBR) Techniques and Biomaterials in Dental Implantology

Abstract

Background: In dental implantology, guided bone regeneration (GBR) is a crucial method for treating alveolar bone deficits. Clinical results have improved because to recent developments in biomaterials and regenerative techniques, but comparative analysis is still crucial.
Aim: To evaluate the effectiveness of advanced GBR techniques and biomaterials on bone regeneration, implant stability, and complication rates over a one-year period.
Materials and Methods: A prospective clinical trial involving one hundred patients who needed GBR for implant implantation was carried out. Four groups of patients (n = 25 each) were created
•
Group 1: Non-resorbable membrane plus autograft
•
Group 2: Collagen membrane plus xenograft
•
Group 3: Collagen membrane plus alloplast
•
Group 4: Platelet-rich fibrin (PRF) with xenograft
At baseline, six months, and twelve months, clinical and radiographic data were evaluated, including complications, implant stability (ISQ), and horizontal and vertical bone growth. ANOVA and Chi-square tests were used for statistical analysis (p < 0.05 was considered significant).
Results: Group 4 showed the most vertical bone gain (3.7 ± 0.6 mm) and horizontal bone gain (4.3 ± 0.7 mm), with Group 2 coming in second. Group 4 had the best implant stability at 12 months (80 ± 2 ISQ). Group 1 had the highest complication rates (20%) and Group 4 had the lowest (6%). Group 4 had the best implant survival rate (98%). Every outcome was statistically significant (p < 0.05).
Conclusion: Advanced GBR methods greatly enhance bone regeneration and implant success while reducing problems, especially when xenografts are used in conjunction with PRF. The incorporation of biologically active materials into standard implant practice is supported by these findings.
