While the deploy planning, we come across morphological changes in the intervention area and the bone volume, which is extremely important for the treatment outcome. The objective of this study is to describe the technique “Split-Crest” through a clinical case in which success was obtained. Demonstrate indications and advantages of the technique in order to gain a significant increase in bone density to achieve an excellent aesthetic and functional result. Female patient, leucoderma, 46 years old, attended the Dental Clinic of Specialization in Implantodontics of ESAMAZ, with report of early teeth loss and poorly adapted prosthesis in the upper anterior region of the pre jaw. During the clinical evaluation was observed Edentulism in the anterior arch of the jaw. Total tomographic filming was done on the jaws, the initial diagnosis was a severe resorption present in the premaxilla requiring regenerative process to achieve bone gain. During surgery the patient had immediate installation of previous implants in the region of the elements 12 and 22 through the technique of “Slplit-Crest”, which consisted of two vertical cuts on the vestibular cortical portion and longitudinal osteotomy followed by the the shift vestibular cortical-spongy plate. Eight weeks later, the patient had clinically significant bone gain, proving the viability and success of the technique. A minimally invasive surgical procedure with well executed manipulation of tissue grafts and accelerates the clinical outcome, the working hours by the end of the treatment is smaller, has lower morbidity and lower operating costs.References
