Abstract

For horizontal bone deficiency alveolar ridge osteotomy is considered an option for augmentation. Major advantages are the option for a one-stage approach and the absence of donor site morbidity. However, the conventional technique is associated with complications such as perforations and fractures of the cortical bone. A case using a 3D based modified, full-guided alveolar ridge expansion is described to explain the technique step by step. Main features of modified technique: successive application of surgical guides for ridge osteotomy and expansion – implementation of virtually determined splitting vector, which allows guided bone splitting along a guide surface of template in an ideal direction - osteotomy as deep as implant length. The example shows that the 3D based modified alveolar ridge osteotomy is a suitable alternative to the conventional technique as it has several advantages such as fewer fractures and perforations of the cortical vestibular bone. The individualized preoperative planning helps to minimize complications. However, long-term outcomes and a study, conducted on a study group, is needed to evaluate the benefits of our presented treatment protocol.
