Podizanje dna nosa - tehnika augmentacije u frontalnoj regiji maksile
Nowadays, dental implants have a high degree of reliability and success when all of the preconditions of an adequate bone foundation are satisfied. Height of the alveolar bone is extremely important for the initial stability of the implant. Premaxilla is one of the most challenging areas for implant-prosthodontic rehabilitation because of the extensive resorptive processes that dominate after tooth loss and, consequently, the proximity of the surrounding anatomical structures, primarily the base of the nose. In such cases, therapy is performed with short implants or procedures of bone height enhancement, such as onlay grafts, guided bone regeneration, or titanium meshes. The literature also mentions the method of augmentation of the premaxilla by raising the floor of the nose. The principle of this method, which is rarely used, is the same as open sinus lift techniques, with the fact that the nasal mucosa is thicker than the Schneiderian membrane. A 72-year-old female patient came to the Department of Oral Surgery for a new prosthodontic solution for her upper jaw. She had been prosthodontically supplied with complete dentures for many years. Clinical examination revealed advanced atrophy of the upper jaw, at the level of the palate bone and with surplus of soft tissue along the remaining ridge. CBCT analysis revealed extensive pneumatization of the base of the nose and maxillary sinuses, without residual bone adequate for implantation. The technique of nasal floor elevation under local anaesthesia was performed on both sides, as a form of augmentation for increasing height in the area of the premaxilla. Through the crestal incision, the base of the nose was accessed through the piriform aperture and through the lateral window distally. The nasal mucosa was raised and the area was augmented with xenogenic material in combination with PRGF fractions F1 and F2, without immediate implantation. The postoperative period was uneventful without complications. This case and the available literature on the topic reveal that nasal floor elevation is a useful and safe method of augmentation in the atrophic premaxilla that can be applied clinically with the same success as the sinus lift technique in the posterior region of the upper jaw.
