ABSTRACT
Los procedimientos quirúrgicos para la aplicación de los implantes en los sectores latero superiores, están condicionadas por la neumatización del seno y la disponibilidad del huesoresidual. En estos casos el injerto de hueso autólogo permanece como lamejor opción, pero a causa de la morbilidad asociada al sitio donante y a las complicaciones post quirúrgicas, se pusieron a disposición diversas alternativas de sustitutos óseos, que implican sin embargo un aumento de los costos económicos y con limitadas propiedades osteoinductivas. Tales defectos pueden ser compensados con nuevas estrategias de regeneración biológica y mecánica de los tejidos a loscuales fue dirigida la ingeniería biológica y mecánica en los últimos años.Se presenta una nueva posibilidad terapéutica en la aplicación de los implantes en el maxilar superior con disponibilidad ósea inferior a los 4 mm, mediante la utilización de andamios 3D confeccionados en cartilago de cerdo libre de antígenos obtenido según la tecnica Fit-Lock. Se realizo un estudio longitudinal en 18 casos consecutivosevidenciando al cabo de un año de la carga implantológica, un éxito del 95,2 por ciento. Las ventajas en esta nueva técnica son: 1)La recuperación funcionaly anatómica del antro del maxilar 2).La aplicación inmediata de los implantes; 3)Reducción de los tiempos quirúrgicos; 4) Ausencia de morbilidad para el paciente; 5) Uso de anestesia local; 6)Uso de implantes con diámetros superiores a los 4 mm

The surgical procedures for implant applications on the lateral-upper areas depend on sinus pneumatization and availability of the residual bone. In these cases, autologous bone grafting remains the gold standard. Nevertheless, because of the morbidity associated to the donor site and the post-surgical complications, several alternative bone substitutes have been introduced, which, however, imply additional costs and show limited osteoinductive properties. Such limitations can be compensated with new regeneration strategies for biological and mechanical tissue restoration, a subject which has been addressed by tissue engineering in recent years. The authors present a new therapeutic option for implant application in the upper maxilla with bone availability less than 4 mm by using 3D scaffolds obtained from antigen-free porcine cartilage in the fit-lock technique. A longitudinal study on 18 consecutive cases was performed, with a 95.2% success rate one year after the implant. The advantages of this new technique are: 1) Functional and anatomical recovery of the maxillary antrum, 2) Immediate application of the implants; 3) Reduction of surgical times; 4) Absence of patient morbidity; 5) Local anesthesia; 6) Use of implants with a diameter > 4 mm.
