Lateral augmentation of the jaw by the split expansion ridge technique. A critical review

Abstract

Bone augmentation has become a routine procedure to enhance and/or repair a deficient or resorbed alveolar ridge for predictable and successful implant placement. The split expansion ridge i.e., the alveolar ridge splitting (ARS) procedure, is one of the less invasive procedures, and is characterized by minor morbidity. This would allow to widen narrow ridges in order to allow implant reconstruction in a sufficient bone volume. Its efficacy and long‐term stability rely upon clinical opinions and long‐term retrospective studies, while prospective comparative studies and randomized controlled trials are rare. This critical review presents the development of this technique, describes the surgical procedure, and provides technical notes and modifications. The learning curve and in‐depth knowledge of the oral anatomy, as well as the recognition of incidence and management of complications are of utmost importance in the clinical application of the ARS procedure.

Efficacy of the Sausage Technique in Rebuilding the Crestal Buccal Bone Thickness: A Retrospective Analysis

“…These techniques include bone blocks and GBR with resorbable membranes, titanium-reinforced non-resorbable membranes, titanium meshes, or other techniques [ 22 , 23 , 24 , 25 , 26 ]. The alveolar ridge-splitting/expansion technique can be used in similar indications, allowing for a reduction in the duration of the treatment in a single surgical phase, with an increased risk of fracture and unpredictable resorption of the cortical bone component [ 27 , 28 , 29 , 30 ]. Historically, bone blocks were the primary option for regenerating bone defects in the alveolar ridge.…”
