The Vestibular Shifted Flap Design for Vertical Bone Augmentation in the Maxilla: Case Report and Technical Notes

Area of Science:

• Oral surgery
• Periodontology
• Regenerative dentistry

Background:

• Primary wound healing is critical for successful bone augmentation outcomes.
• Maxillary bone augmentation often involves crestal incisions, potentially leading to inadequate palatal flap length.
• Dense connective tissue of the palatal flap hinders eversion, compromising wound closure and primary healing.

Observation:

• A case report details a new incision design for improved palatal flap management during maxillary bone augmentation.
• This technique achieves palatal flap verticalization by shifting the incision line onto the vestibular side.
• The adjusted flap length ensures adequate coverage over the bone graft site.

Findings:

• The modified incision design facilitates optimal adaptation between palatal and vestibular flaps.
• This approach simplifies achieving a secure wound seal, crucial for primary healing.
• The technique reduces the risk of non-primary wound healing, enhancing treatment predictability.

Implications:

• This technique offers a practical solution for improving wound closure in maxillary bone augmentation.
• Enhanced primary healing can lead to more predictable and successful bone graft integration.
• The described incision strategy may be beneficial for various bone augmentation procedures requiring adequate soft tissue coverage.
