Por qué importa

Este estudio evalúa la técnica de elevación del suelo del seno maxilar mediante osteotomo sin biomateriales, una alternativa de acceso crestal para la colocación de implantes en el sector posterior del maxilar con escasa disponibilidad ósea, inferior a 5 mm. La técnica propuesta busca optimizar la estabilidad primaria del implante y favorecer la osteointegración, permitiendo la carga a las 12 semanas. Los resultados reportan una tasa de supervivencia del 100% para los 32 implantes colocados, observándose formación ósea espontánea. Esta metodología podría representar una reducción del tiempo de tratamiento y evitar técnicas de aumento más invasivas, siendo relevante para la práctica clínica en la rehabilitación de edentulismos posteriores.

Abstract original

According to classic Hirschfeld studies, the first teeth to be lost are the first and second maxillary molars. After the teeth are extracted and the alveolar process is developed, the maxillary sinus is reabsorbed and pneumatized with a decrease in bone availability in the posterior sector of the maxilla. This process often creates the need to perform regeneration techniques for the placement of implants in this area due to the low availability of bone. The most frequently used and documented technique for the elevation of the sinus maxillary floor is elevation by the side window, as proposed by Tatum. In 1994, Summers proposed a technique that allowed the elevation of the sinus floor from a crestal access using an instrument called an osteotome, as well as the placement of the implant in the same surgical act. The aimed of the study was to evaluate the survival of 32 implants placed in posterior maxilla with bone availability less than 5 mm performing a sinus lift augmentation technique with osteotome without biomaterials. The results of this study show a survival rate of 100% for 32 implants placed in situations with an initial bone availability of 2 to 5 mm without the use of graft material. The infra-drilling technique used offers an increase in the primary stability of implants that allows adequate osteointegration. Implants placed were charged at 12 weeks. In all cases, spontaneous bone formation was observed, even in cases where a positive Valsalva maneuver was observed. This proposed technique reduces treatment time and the need for more invasive maxillary sinus augmentation techniques.
