Abstract
Introduction. In the case of patients with reduced vestibular-palatal or vestibular-lingual ridges with a dimension under 3-4 mm, in order to allow the insertion of endoosseous implants, we are forced, more than often, to resort to osseous grafts. The bone splitting method allows, with the help of piezosurgery tools, to increase the intracortical distance and to regenerate the bony structure in a guided way, with a success rate up to 98%. Material and method. The bone splitting method was used in the case of 65-year-old female patient, who, at the level of 22, had internal radicular resorption with mobility of III degree. The patient asked for both a provisory as well as a permanent aesthetic solution regarding the replacement of 22 after extraction. Therefore, we used the 3D scanner in order to determine the osseous dimension necessary for an implant insertion and, as a result of the clinical examination, the patient had an intracortical vestibular-palatal dimension of 3 mm. In this clinical study, the decision was to augment the ridge through the bone splitting method and to insert a 3.7 mm implant in diameter and 8 mm in length at the level of 22 area. Conclusions. During the same visit we performed the extraction, the bony augmentation of the ridge, the insertion of the implant and a provisory crown was cemented. As a result of the augmentation, the intracortical diameter increased from 3 mm to 5 mm and the patient was given a permanent prosthesis 2 month after implant insertion.

Summary
TEHNICA BONE-SPLIT ÎN CAZUL CRESTELOR OSOASE DE DIMENSIUNI REDUSE – PREZENTARE DE CAZ. Tehnica bone-split s-a folosit în cazul unei paciente cu vârsta de 65 de ani, care la nivelul lui 22 prezenta o resorbţie radiculară internă, cu mobilitate de gradul III. Am folosit scanerul 3D pentru determinarea dimensiunii osoase necesară inserării unui implant şi, în urma examinării, pacienta prezenta o dimensiune intracorticală vestibulo-palatină de 3 mm. Decizia luată a fost de augmentare a crestei prin tehnica bone-split şi inserarea unui implant de [3,7] mm în diametru şi 8 mm în lungime la nivelul zonei lui 22. Diametrul intracortical a crescut de la 3 mm la 5 mm, iar pacienta a fost protezată definitiv după două luni de la inserarea implantului
