A solidified bone graft trapped in a fibrin network prevents its dispersion even when subjected to movement or shaking. The Split Crest technique offers a practical way to expand the atrophic alveolar ridge. This allows the use of bone grafts without needing a second surgical site, which reduces the risk of edema, nerve injuries, and pain. A 50-year-old patient, systematically healthy, reported difficulty chewing, swallowing, and speech due to a poorly adapted prosthesis in the jaw, which caused dissatisfaction with the prosthetic treatment already performed. This case report aimed to describe the Sticky Bone procedure by adding an autologous atrophic jaw graft using the Split Crest technique, obtaining an average bone gain of 2.5mm, having good results after eight months postoperatively, there was no peri-implant marginal bone resorption.]]></p></abstract>

Un injerto óseo solidificado atrapado en una red de fibrina impide su dispersión incluso cuando se somete a movimientos. La técnica Split Crest ofrece una soluciòn práctica para expandir la cresta alveolar atrófica utilizando injertos óseos, sin necesidad de un segundo lecho quirúrgico, reduciendo el riesgo de edema, lesiones nerviosas y dolor. Un paciente de 50 años de edad, sistemáticamente sano, refirió dificultades para masticar, tragar y hablar debido a un tratamiento protésico ya realizado. Este caso clínico buscò describir el procedimiento Sticky Bone mediante la adición de un injerto maxilar autólogo atrófico utilizando la técnica Split Crest, obteniendo una ganancia ósea media de 2,5 mm, observándose buenos resultados después de ocho meses postoperatorios, sin reabsorción ósea marginal periimplantaria.]]></p></abstract>
