Por qué importa

Este estudio aleatorizado de cinco años evalúa el impacto del protocolo de colocación del pilar definitivo el mismo día de la entrega protésica, comparado con el estándar de cuidado que implica el uso y retirada de pilares de cicatrización. Se analizaron parámetros clínicos radiográficos como el nivel óseo interproximal, sangrado gingival, profundidad de sondaje, índice de placa y relleno papilar, además de la incidencia de mucositis y periimplantitis, y resultados reportados por el paciente. Los hallazgos indican que la manipulación del pilar de cicatrización durante la curación no se asoció con mayor pérdida ósea a largo plazo, y los resultados clínicos y la satisfacción del paciente fueron similares entre ambos grupos, sugiriendo que el protocolo de 'one-abutment one-time' es una alternativa viable sin comprometer la salud periimplantaria.

Abstract original

OBJECTIVE: The aim of this study was to evaluate the long-term (5 years) clinical efficacy of the one-abutment one-time protocol (test) versus the standard of care by placing the definitive abutment on the day of the prosthetic delivery (control). MATERIALS AND METHODS: In this study, 39 subjects with 60 implants were randomly allocated to either the test or the control group. Changes in the radiographic interproximal bone levels (DIB), modified sulcus bleeding index, probing depth, modified plaque index, papilla fill (Jemt score), incidence of peri-implantitis and peri-implant mucositis as well as patient-reported outcomes measures (PROMs) were collected and compared at 1, 3 and 5 years. RESULTS: At 5 years, the control group showed a greater, although not statistically significant, change in mean DIB values (0.97 mm vs. 0.53 mm). Regarding the other clinical parameters evaluated, no statistically significant differences were observed between groups at any time point. At 5 years, 51% of the implants presented peri-implant mucositis (25.5% in the control and 23.5% in the test), and only one implant in the test group developed peri-implantitis. CONCLUSIONS: The connection and disconnection of healing abutments during the healing period was not associated with higher long-term bone loss. Clinical outcomes and PROMs were similar between groups.
