Horizontal Ridge Augmentation in Mandible Usign ROG + ESWT

Guided bone regeneration (GBR) has been the most frequently used option to treat bone ridge deficiencies, allowing to restore such defects in order to place bone-integrated dental implants. A few reports exist in the literature about the augmentation of mandibular horizontal ridge defects before implant placement. Published studies show a large variability of reported results regarding horizontal bone augmentation. This can be due to the use of different types of membranes and bone graft materials or a combination thereof. Likewise, an important percentage of graft reabsorption is reported. Although this technique is very much used, an important number of cases must be re-treated or require placing bone graft during implant installation surgery. Techniques are required in order to improve vascularization of the grafts during GBR technique with the aim to improve their clinical success. Recent studies show great interest on the application of shock waves in oral diseases associated to infection and bone loss. The shock waves are acoustic waves that have effects on human biological tissues, stimulating the neo-angiogenesis and the development of a hyper cellularity, showing repairing characteristics on tissues, and starting regenerative processes as a result of metabolism improvement and the increase of local circulation. The extra corporeal shock waves can activate the osteoblasts and their precursors and they have been widely used in orthopaedics for repairing bone fractures. Several clinical studies have shown the effectiveness and safety of shock wave therapy in myocardial revascularization, lithotripsy, cellulitis, volar fasciitis, osteonecrosis, bone fractures, and complicated injuries of soft tissues. No clinical studies exist that assess its effect on guided bone regeneration. The evidence related to the positive effects of the use of shock waves on bone regeneration suggests this treatment as a novelty and a promising therapy that combined with the GBR techni
