An innovative approach to three-dimensional ridge augmentation in the posterior mandible: A case report

Introduction and importance: Surgical intervention is necessary to address significant three-dimensional bone loss in the posterior mandibular alveolar ridge when implants are planned, and primary stability cannot be achieved due to anatomical limitations. The objective of this study is to elucidate the surgical procedures for reconstructing significant bone loss in the posterior mandibular region and to present the outcomes and insights gained from this clinical case. Case presentation: A 42-year-old woman exhibited first lower molar loss, significant movement of the second molar, and severe bone loss at the same site. Vertical and horizontal bone augmentation was performed to enable the restoration of teeth loss by inserting dental implants. Clinical discussion: Significant bone loss poses a great limitation in replacing missing teeth, particularly in the posterior mandible, given anatomical constraints. Therefore, it is essential to establish an adequate amount of bone to ensure primary stability for the implants. Conclusion: This clinical case demonstrates a restoration technique of severe bone loss in the posterior mandible to enable stable dental implant placement, highlighting the importance of combining vertical and horizontal augmentation to overcome anatomical limitations and ensure primary stability.
