ABSTRACT
Abstract Objective: To evaluate the efficacy of the technique for ridge augmentation prior to implant placement. Material and Methods: Six patients with nine sites presenting an initial ridge width of smaller than 4 mm were included in this study. The tent-pole technique (combination of osteosynthesis screws measuring 1.5 mm in diameter, ABBM, and resorbable collagen membrane) was applied at defect sites. After eight months of healing time, implants were placed in the treated sites. The primary outcomes (radiographic initial ridge width, re-entry ridge width, ridge width gain) were measured by cone-beam computed tomography in reference buccopalatal cross-sections and the secondary outcomes (clinical parameters) were recorded by a digital caliper at the first and second stages. Results: After grafting, the radiographic ridge width increased by 3.02 ± 1.11 mm (1.57-4.75 mm) at 2 mm below the crest and 3.32 ± 1.70 mm (0.23-5.66 mm) at 6 mm below the crest significantly (p< 0.05). For clinical results, the mean horizontal dimension gain was 3.21 ± 1.04 mm (1.83-4.57 mm), while the mean reduction in dimension was 0.38 ± 0.33 mm. These results were statistically significant (p<0.05). Uneventful healing and no infections or membrane exposure were recorded at all sites during the study process. Three of nine (33.33%) defect sites required additional bone grafting. Conclusion: The tent-pole technique is an effective method for increasing the horizontal ridge dimension, minimizing postoperative complications, and facilitating subsequent implant placement.

El objetivo de la terapia reconstructiva periodontal es obtener la maduración del periodonto, en sitios en donde existe lesión periodontal previa, con formación de nuevo cemento, nuevo ligamento periodontal y nuevo hueso alveolar. El tema de este trabajo intenta abordar cuáles son los materiales y procedimientos para retardar la proliferación apical del epitelio gingival y permitir la formación de una nueva inserción. El uso de membranas y de rellenos óseos da lugar al principio de RTG. La membrana impide que el tejido conjuntivo entre en contacto con la superficie radicular, dejando un espacio cerrado entre la barrera, la raíz y las paredes del defecto óseo, y actuando como barrera selectiva y mantenedor de espacio. Los rellenos óseos contienen células que pueden forma nuevo hueso cuando son implantadas en defectos periodontales intraóseos. La utilización de RTG posibilita la rehabilitación en cuanto a arquitectura y función del periodonto destruido por la infección
