Horizontal bone augmentation and simultaneous implant placement using xenogeneic bone rings technique: a...

Area of Science:

• Dentistry
• Oral Surgery
• Regenerative Medicine

Background:

• Horizontal alveolar bone defects pose challenges for dental implant placement.
• Bone augmentation is crucial for achieving stable and aesthetic implant restorations.

Purpose of the Study:

• To evaluate the efficacy of the bone ring technique with xenogeneic bone grafts for horizontal bone augmentation.
• To assess implant survival rates and peri-implant tissue conditions following the procedure.

Main Methods:

• Retrospective study of 11 patients with horizontal alveolar bone defects.
• Simultaneous bone augmentation using xenogeneic bone ring grafts and dental implant placement.
• Postoperative evaluation using radiographical (Cone-beam computed tomography) and clinical parameters.

Main Results:

• 100% implant survival rate observed over the follow-up period.
• Significant horizontal bone augmentation achieved below the implant neck platform (0-3 mm).
• Excellent peri-implant tissue conditions were maintained during the 1-year follow-up post-loading.

Conclusions:

• The bone ring technique with xenogeneic bone grafts is a viable option for treating severe horizontal bone defects.
• This technique effectively increases and maintains horizontal bone mass around implant neck platforms.
• The method supports favorable outcomes for dental implant rehabilitation in augmented bone sites.
