Abstract

Objective: To propose a new difficulty classification for vertical bone augmentation (VBA) based on different defect morphologies. Overview: VBA procedures for dental implant placement present significant biological and technical challenges. Among the various techniques, guided bone regeneration (GBR) provides an optimal balance between the anticipated bone gain and the likelihood of postoperative complications. Understanding the specific configuration of defects and adjacent bone peaks is essential for tailoring treatment strategies and improving outcomes. The proposed Simple-Challenging-Difficult (SCD) difficulty classification was based on defect morphology (V-shaped, U-shaped, VV-shaped), including defect size (Height: < 5 mm, 5-8 mm, and > 8 mm), proximity of neighboring bony walls (Width: < 10 mm, 10-20 mm, and > 20 mm), as well as predictability of treatment outcomes. Conclusions: The proposed difficulty classification for VBA serves as a guide for selecting the most appropriate GBR treatment modality and sequence for safe and predictable management of VBA in implant therapy. In addition, when determining the preferred treatment, it is again essential to consider site-specific and patient-related factors alongside the clinician's surgical experience and skill. Clinical Significance: Identifying defect patterns and bone peak structures is crucial, and the proposed classification assists in decision-making in VBA treatment.
