Cortical Mandibular Bone Blocks Grafts and Piezoelectric Surgery in Complex Anterior Maxillary Alveolar Defects: A Case Report and Literature Review

Abstract

The aim of this study is to assess the indication and efficacy of alveolar ridge reconstructions for complex horizontal and vertical augmentation procedures in the maxillary anterior area with Cortical Mandibular Bone Block Grafts (CMBBG). Localized alveolar three-dimensional bone defects are among the most challenging problems in surgical implant dentistry. Treatment protocols, such as short implants or small diameter implants are not always offering the desired clinical and esthetic results. The autogenous augmentation procedure can serve as an option, which allows a more biological reconstruction of the vertical and horizontal dimension of a complex bone defect in order to obtain sound replicas of natural teeth. The clinical case of a cortical autogenous block graft in an anterior complex maxillary defect is presented along with a literature review. The presented case and the selected articles demonstrate that cortical ramus bone block grafts show relatively low graft resorption, low donor site morbidity and high implant success rates.
