RESUMO
BACKGROUND: The aim of this study was to evaluate the efficacy of a hydrodynamic ultrasonic driven transcrestal sinus grafting procedure (Intralift (R), Acteon Company, Bordeaux, France) and the use of a bovine high temperature sintered grafting material in sinus sites with less than 5 mm remaining bone height with no additional autogenous bone in order to create a sufficient recipient site for implants. MATERIAL AND METHODS: 12 patients (16 sinus) in this multicenter case study were included. Using a crestal approach, bone under the sinus was prepared with ultrasonic tips until the Schneiderian membrane was reached. With a trumpet shaped instrument, the Schneiderian membrane was elevated. In the new created subantral space a high temperature sintered bovine grafting material was introduced (Bego Oss, BEGO Implant Systems GmbH & Co. KG, Bremen, Germany). After 6 months biopsies were taken with a trephine bur and histologies were generated following histomorphometric analysis. RESULTS: The results showed new vital bone in average of 33.4% ± 17.05%, and 43.6% ± 16.70 of bone substitute material. No signs of abnormal inflammation were observed. CONCLUSIONS: This procedure (Intralift (R)) allows, using a bovine material with no additional autogenous bone, new bone formation in the sinus in order to allow place implant subantraly

El uso material de relleno para aumento de tejidos blandos data de finales del Siglo XIX. Se han utilizado una larga lista de materiales como grasa autóloga, parafina, silicona, colágeno bovino, que sigue creciendo en la actualidad. Su mecanismo de acción es similar en todos ellos: se trata de materiales supuestamente inertes que al ser infiltrados provocan un aumento de volumen. Nuestro trabajo repasa los materiales semipermanentes y permanentes existentes en la actualidad, ya sean semipermanentes (aquellos cuya duración se aproxima al año) o permanentes (no biodegradables). Entre los primeros se encuentra el ácido poliláctico, cuya duración oscila entre los 12 y 18 meses y la Hidroxiapatita de calcio, de duración similar al anterior. En el segundo grupo hallamos al metacrilato, las acrilamidas y las polialquilimidas (AU)
The use of filler material to increase soft tissue dating from the last nineteenth century. We used a long list of materials such as autologous fat, paraffin, silicone, bovine collagen, which keeps growing at present. The mechanism of action is similar in all of them: this is supposedly inert materials to be infiltrated to cause an increase in volume. Our study reviews the materials semi-permanent and permanent that exist nowaday, semi-permanent (whose duration is about a year) or permanent (not biodegradable). Included in the first group we can findpolylactic acid, whose duration ranged between 12 and 18 months and calcium hydroxyapatite, similar to the previous term. The second group are the methacrylate, acrylamide and the polialquilimidas (AU)
