Flap Extension Technique Using Intrasocket Granulation Tissue in Peri-Implant Osseous Defect: Case Series

Area of Science:

• Dentistry
• Oral Surgery
• Regenerative Medicine

Background:

• Compromised extraction sockets exhibit bone resorption and are filled with intrasocket granulation tissue (IGT).
• Guided bone regeneration (GBR) aims to preserve bone volume and can be combined with immediate implant placement.
• Early GBR site exposure is a complication, increasing infection risk and hindering bone regeneration.

Observation:

• A novel surgical technique was developed to prevent GBR site exposure using IGT for flap extension.
• The technique involves dissecting IGT for flap extension, maintaining its blood supply, and suturing it to the palatal flap.
• Periosteal releasing incisions were not required.

Findings:

• The technique was successfully applied in six patients, with no post-operative exposure of GBR sites.
• The mucogingival junction location remained stable post-surgery.
• All grafted sites demonstrated sufficient bone regeneration.

Implications:

• This case series suggests that IGT can be effectively utilized for flap extension in GBR procedures.
• The technique offers a potential solution to prevent GBR site exposure, enhancing treatment outcomes.
• This approach revives the use of IGT in oral surgery, previously considered obsolete.
