Horizontal ridge augmentation and implantation in the mandible using a Customized Allogenic Bone Block with BLX implants
A clinical case report by Orcan Yüksel, Germany
Atrophy of the mandibular bone caused by premature tooth loss due to periodontal or endodontic problems can often be found in posterior areas. Problems associated with implantation in these cases often arise due to limited bone height or width of the mandible, and several treatment options have been suggested to gain enough bone for a stable implantation and achieve an esthetically good result.1 In clinical practice, freeze-dried bone allograft (FDBA) blocks have been used for alveolar ridge augmentation with promising results, offering patients a less-invasive treatment alternative to autogenous bone blocks, with no donor site morbidity and no second surgical site.2,3,4 Nowadays, customized allogenic bone blocks can be produced using the computer-aided design/computer-aided manufacturing (CAD/CAM) technology, enabling a shorter surgery time as manual block adjustment during surgery becomes unnecessary, thus enhancing patient comfort.5,6 This case report describes a two-stage Guided Bone Regeneration (GBR) procedure using a customized allogenic bone block as a first step to increase the horizontal mandibular bone width. In a second step, special newly designed implants (Straumann® BLX Roxolid® SLActive®) were inserted to achieve good primary stability.
