Este artículo describe nuestra experiencia en su uso para la rehabilitación completa del maxilar superior. Pacientes y métodos: Se presenta un estudio retrospectivo de 8 pacientes edéntulos con atrofia ósea grave del maxilar superior, tratados mediante estructuras de titanio personalizadas diseñadas y fabricadas en conjunto con la empresa Avinent Digital Health (Barcelona, España). Las estructuras se diseñan a partir de un TC maxilomandibular con cortes finos. Como guía de referencia se emplea una prótesis completa acrílica con marcas radiopacas. Las estructuras se diseñan en dos o tres piezas para favorecer su inserción y adaptación a los contornos óseos. La cirugía se lleva a cabo bajo anestesia general, e incluye colgajo de bola de Bichat bilateral previo al cierre mucoso. Inmediatamente tras la cirugía se coloca una prótesis fija provisional implantosoportada, que se sustituye por una prótesis fija de cerámica o híbrida a las 8-12 semanas.  Resultados:  Todos los pacientes llevan actualmente la prótesis fija final, con un tiempo de seguimiento de 4 a 36 meses. En ningún caso ha sido necesario retirar ni recortar el implante. Todos los pacientes están asintomáticos.  Conclusión:  Aunque se trata de un estudio preliminar, los resultados indican que esta técnica debe ser considerada una alternativa de tratamiento en atrofias maxilares graves.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT  Introduction:  Customized subperiosteal implants are presented as an alternative in the implant-supported rehabilitation of patients with severe bone atrophy. This article describes our experience in their use for complete maxillary rehabilitation.  Patients and methods:  A retrospective study of 8 edentulous patients with severe maxillary bone atrophy treated with customized titanium frameworks designed and manufactured in conjunction with Avinent Digital Health (Barcelona, Spain) is presented. The frameworks are designed based on a thin-slice maxillomandibular CT scan. A full acrylic prosthesis with radio-opaque markings is used as a reference guide. The structures are designed in two or three pieces to favor their insertion and adaptation to the bone contours. The surgery is performed under general anesthesia, and includes bilateral buccal fat pad flap prior to mucosal closure. Immediately after surgery an implant-supported temporary fixed prosthesis is placed, which is replaced by a fixed ceramic or hybrid prosthesis after 8-12 weeks.  Results:  All patients are currently wearing the final fixed prosthesis, with a follow-up time of 4 to 36 months. In no case has it been necessary to remove or trim the implant. All patients are asymptomatic.  Conclusion:  Although this is a preliminary study, the results indicate that this technique should be considered as a treatment alternative in severe maxillary atrophy.]]></p></abstract>
