A liquid membrane as a barrier membrane for guided bone regeneration

Area of Science:

• Biomaterials Science
• Dental Implantology
• Regenerative Medicine

Background:

• Various barrier membranes exist for guided bone regeneration (GBR), including non-resorbable, resorbable, and liquid-applicable types.
• Liquid-applicable membranes offer potential advantages in GBR procedures.

Purpose of the Study:

• To evaluate the efficacy of in situ applied Atrisorb as a barrier membrane for guided bone regeneration.
• To assess the clinical outcomes and complication rates associated with Atrisorb use in alveolar ridge augmentation.

Main Methods:

• Atrisorb, a liquid-applicable membrane, was used with bone grafts in 10 patients requiring alveolar ridge augmentation.
• Treatment was performed in 10 sites, either prior to or in conjunction with dental implant placement.
• Augmented sites were allowed to heal for 3 to 7 months (mean 4.7 months).

Main Results:

• Healing was generally uneventful, with no major complications reported.
• Two sites (20%) experienced flap dehiscence and barrier exposure, achieving secondary healing without infection.
• The barrier exposure rate was comparable to that of traditional resorbable membranes.

Conclusions:

• In situ application of Atrisorb shows potential as a viable alternative to conventional resorbable membranes for GBR.
• Atrisorb demonstrates a manageable complication profile, suggesting its suitability for alveolar ridge augmentation procedures.
