The bone lid technique in oral surgery: a case series study

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Medicine
• Biomaterials Science

Background:

• Mandibular alveolar bone diseases pose treatment challenges.
• Traditional ostectomy techniques can lead to significant bone loss.
• Minimally invasive surgical approaches are needed for bone tissue healing.

Purpose of the Study:

• To illustrate the bone lid technique using piezoelectric surgery for accessing mandibular alveolar bone diseases.
• To evaluate the clinical and radiographic outcomes of this technique.
• To assess bone lid integration and alveolar bone volume recovery.

Main Methods:

• A case series of 21 patients with various mandibular alveolar bone conditions.
• Piezoelectric surgery utilized for precise osteotomy to create a bone lid.
• Bone lid replacement and fixation with miniplates, followed by 12-month follow-up.
• Computed tomography (CT) volumetric analysis for bone volume assessment.

Main Results:

• Successful healing and bone lid integration in 19 out of 21 patients.
• Mean recovery of 93.8% of lost alveolar bone volume in CT analyses.
• One case of permanent mild paresthesia and one of bone lid necrosis reported.
• The technique proved effective for cysts, keratocystic odontogenic tumors, and endodontic lesions.

Conclusions:

• The bone lid technique with piezoelectric surgery and rigid fixation is a promising alternative to ostectomy.
• This approach facilitates effective bone tissue healing and volume restoration.
• Further research may validate its broader application in oral and maxillofacial surgery.
