The efficacy of osteocoral as an implant material in the treatment of infraosseous bags in multiradical teeth is evaluated. We analyzed 14 patients divided into 2 groups: the first included 6 patients with a total of 12 defects, which were evaluated up to 6 months. The second, with 8 patients and 16 defects, which were re-evaluated at 12 and 24 months. In both groups, patients of both sexes were included, who were implanted with osteocoral (study group) and with hydroxyapatite (control group). Initial repair was performed that included removal of calculus and polishing of the tooth surface, education and motivation and evaluation of brushing, which should show values equal to or greater than 80% in the removal of dentobacterial plaque. Subsequently, the implant was performed by flap operation. Control X-rays were taken at 14 days, 6 months (for the first group) and 12 and 24 months (for the second group). Oral hygiene was systematically controlled in both groups. The clinical indicators were checked again at 6 months for the first group, and at 12 and 24 months for the second. A statistically significant decrease was observed in the gingival index, depth of the pouch and dental mobility for both implant materials, without large differences between them being reported. Radiographically, the presence of filler was observed in the original defect, and there were no adverse local reactions, so treatment was considered effective.Se evalúa la eficacia del osteocoral como material de implante en el tratamiento de bolsas infraóseas en dientes multirradiculares. Se analizaron 14 pacientes que se dividieron en 2 grupos: el primero incluyó a 6 pacientes con un total de 12 defectos, los cuales se evaluaron hasta los 6 meses. El segundo, con 8 pacientes y 16 defectos, que se reevaluaron a los 12 y 24 meses. En los 2 grupos se incluyeron pacientes de ambos sexos, que fueron implantados con osteocoral (grupo estudio) y con hidroxiapatita (grupo control). Se realizó reparación inicial que incluyó remoción de cálculo y pulido de la superficie dentaria, educación y motivación y evaluación del cepillado, que debía mostrar valores iguales o mayores del 80 % en la remoción de placa dentobacteriana. Posteriormente se realizó el implante mediante operación a colgajo. Se realizaron radiografías de control a los 14 días, 6 meses (para el primer grupo) y 12 y 24 meses (para el segundo grupo). Se controló sistemáticamente la higiene bucal en ambos grupos. Se controlaron nuevamente los indicadores clínicos a los 6 meses para el primer grupo, y a los 12 y 24 meses para el segundo. Se observó una disminución estadísticamente significativa en el índice gingival, profundidad de la bolsa y movilidad dentaria para ambos materiales implantológicos, sin que se reportaran grandes diferencias entre éstos. Radiográficamente se observó la presencia de relleno en el defecto original, y no hubo reacciones locales adversas, por lo que se consideró efectivo el tratamiento
