Abstract
Loss of anterior teeth can be caused by pathological processes, tooth retention (mostly upper canine), result of trauma (avulsion or root fracture) or missing tooth germ.
Such defects can be solved by orthodontic treatment (orthodontic space closure), prosthetic treatment (different bridge constructions) or with surgery treatment (dental implants). Inadequancy of orthodontic therapy is long lasting rehabilitation ond mostly esthetical imperfection. At the bridge constructions, hard tissues of adjacent teeth must be removed. Another contraindication is the presence of diastemas. Dental implants enable making selfsupporting mastication units, but require sufficient bone to adequately stabilise. When there are changes in alveolar bone height and width, we use guided bone regeneration (GBR). GBR has proved to be a suitable technique for promoting bone regeneration. GBR treatment with collagen membranes may significantly enhance bone regeneration.
The left first incisor of a 27 years old patient was extracted because of resorptive processes on alveolar bone as a result of longitudinal fracture of the root. Immediately after extraction, the bone defect was filled with Bio-Oss spongiosa granules and covered with Bio-Gide resorbable bilayer mambrane. After one year the defect was restored to nearly original condition and ITI Straumann implant was placed. Because of labial dehiscence Fisiograft was used. The definitive restoration was placed after 6 months.
