Subperiosteal Ridge Augmentation Technique Utilizing Sticky Bone: A Case Series

Area of Science:

• Oral surgery
• Regenerative medicine
• Dental implantology

Background:

• Conventional bone ridge augmentation techniques can lead to significant postoperative complications.
• There is a need for minimally invasive methods to address alveolar ridge defects for dental implant placement.

Observation:

• A novel minimally invasive subperiosteal technique was applied to augment four edentulous sites with class I and III ridge defects.
• The technique involved creating subperiosteal pouches and filling them with 'sticky bone' (injectable platelet-rich fibrin and xenograft).
• Delayed implant placement was performed after 180 days, with bone samples collected for analysis.

Findings:

• Cone-beam computed tomography (CBCT) demonstrated dimensional changes post-augmentation.
• Histological and histomorphometric analyses of bone samples confirmed successful bone regeneration.
• The modified subperiosteal tunneling technique with sticky bone proved effective in ridge augmentation.

Implications:

• This minimally invasive approach offers a potentially reliable alternative for alveolar ridge augmentation.
• The technique may reduce patient morbidity and improve predictability in dental implant therapy.
• Further research could validate this method in larger clinical trials for broader application.
