Maxillary sinus augmentation using growth factors and collagen membranes (regeneración ósea del seno maxilar. Estudio sobre la utilización de factores de crecimiento y membranas biológicas)

Résumé

Traditional management of patients with missing teeth formerly involved the use of a variety of fixed or removable prostheses designed to utilize selected teeth (Bryan & Zarb 1998). However, many patients with removable prostheses experience difficulty achieving comfortable and efficient function. Fortunately, maladaptive complete denture patients respond very well to implant prostheses (Zarb & Schmitl 1989). The use of implants to prosthetically restore function and esthetics following the loss of teeth has become a common treatment alternative to conventional tooth-supported fixed or removable recontructions, mainly due to the benefit of avoiding the sacrifice of intact structure of adjacent teeth. However, a common problem of encountered in implant dentistry is insufficient bone quantity to allow implant placement according to standard protocol. Various clinical techniques have been developed to address these bone deficiency problems (Tonetti & Hämmerle 2008).
