Bone augmentation in dental implants among Indian patients.

Area of Science:

• Dental implantology
• Oral surgery
• Regenerative medicine

Background:

• Vertical alveolar bone loss presents challenges for dental implant placement.
• Various techniques exist to augment deficient alveolar ridges, including guided bone regeneration (GBR) and distraction osteogenesis (DO).

Purpose of the Study:

• To compare the efficacy of different bone regeneration techniques for vertical alveolar ridge augmentation.
• To evaluate implant success, survival rates, and ridge resorption following augmentation.

Main Methods:

• Comparison of GBR with titanium mesh, DO, GBR with autogenous bone and e-PTFE membranes, and onlay bone grafts.
• Assessment of dental implant success and survival.
• Evaluation of peri-implant clinical parameters at 1, 2, and 3 years post-loading.
• Measurement of alveolar ridge resorption before and after augmentation and implant placement.

Main Results:

• Distraction osteogenesis (DO) demonstrated more predictable long-term vertical bone growth.
• All investigated methods contributed to the repair of vertically resorbed edentulous ridges.
• Implant success and survival rates were assessed across all techniques.

Conclusions:

• Distraction osteogenesis (DO) offers a predictable approach for long-term vertical bone regeneration in atrophic alveolar ridges.
• While DO shows superior predictability, guided bone regeneration (GBR) and bone grafting techniques also provide viable solutions for ridge augmentation.
• All methods evaluated contribute to restoring the capacity of alveolar ridges to support dental implants.
