GOMEZ ARCILA, Verónica et al. Guided bone regeneration: new advances in the treatment of bone defects. Rev Cubana Estomatol [online]. 2014, vol.51, n.2, pp.187-194. ISSN 0034-7507.

Introduction: the procedure of guided bone regeneration has proven to be a successful technique to promote the filling of bone defects and enlarge the dimensions of atrophic alveolar ridges prior to conventional or implant-supported prosthetic rehabilitation. Objective: describe the clinical use of b-tricalcium phosphate alloplastic graft as a filler material in the regeneration of alveolar bone defects. Case report: a female 57-year-old patient presented at dentistry consultation with exudate from an upper anterior tooth due to apical infection. Clinical examination revealed root rests of the upper left central incisor and upper left lateral incisor. Radiography showed root fracture of the upper right central incisor. Upon extraction of the root rests, guided bone regeneration technique was performed, using b-tricalcium phosphate alloplastic grafting with a resorbable collagen membrane. Three months after treatment, an increase in height and width of the alveolar ridge was observed, achieving the desired aesthetic and functional status. Conclusions: satisfactory clinical results in terms of bone neoformation are due to adequate therapeutic planning and the employment of guided bone regeneration. Use of bone grafting, specifically alloplastic graft of b-tricalcium phosphate in combination with barrier membrane, is thus suggested for the management of alveolar bone defects.
