Guided Bone Regeneration for Horizontal Maxillary Alveolar Ridge Augmentation Using Patient-Specific Solid Titanium...

Area of Science:

• Dental implantology
• Periodontics
• Oral and Maxillofacial Surgery

Background:

• Alveolar ridge augmentation is crucial for dental implant success, especially in the esthetic zone.
• Guided bone regeneration (GBR) techniques aim to enhance bone volume for implant placement.

Purpose of the Study:

• To evaluate radiographic and histomorphometric outcomes of horizontal maxillary alveolar ridge augmentation.
• To assess the efficacy of solid, nonperforated, customized titanium barriers in GBR procedures.

Main Methods:

• A case series involving eight patients undergoing GBR in the anterior maxillary esthetic zone.
• Patient-specific solid titanium barriers were used with a mix of autogenous and xenogenic bone grafts.
• Radiographic analysis (CBCT) at immediate, 4-month, and 10-month intervals; histomorphometric analysis of bone core specimens.

Main Results:

• Statistically significant horizontal bone gain was observed over time (P < .001).
• The mean area of newly formed bone was 79.6% ± 29.2%.
• Wound healing was generally uneventful, with minor soft tissue breakdown not impacting outcomes.

Conclusions:

• Customized solid titanium barriers are an efficient and promising approach for GBR.
• This method facilitates significant horizontal bone gain and improves augmented site quality for dental implants.
