Por qué importa

Un ensayo clínico piloto aleatorizado evaluó los cambios óseos marginales en implantes con un recubrimiento multifosfonato, comparando protocolos de carga temprana (4 semanas tras colocación) frente a carga convencional (8 semanas tras colocación). Los resultados, seguidos hasta 1 año, indican que ambos protocolos son exitosos radiográficamente, sin diferencias significativas en el nivel óseo marginal entre grupos ni a lo largo del tiempo. Aunque el espesor del tejido blando fue menor en el grupo de carga temprana, esto no impactó negativamente en el mantenimiento del hueso crestal. Esta investigación aporta información relevante para la toma de decisiones clínicas sobre la elección del protocolo de carga, sugiriendo que implantes con este tipo de recubrimiento permiten flexibilidad en el momento de la carga sin comprometer la estabilidad ósea marginal a corto plazo.

Abstract original

Objectives To compare the marginal bone level around implants with a thin multi-phosphonate coated surface after either an early or conventional loading protocol. Material and methods A randomized pilot clinical trial was conducted. Dental impressions were obtained after either 4 (test) or 8 weeks (control) and single crowns screwed-in 2 weeks later. Several variables were evaluated including radiographical marginal bone level (MBL), patient's level variables, and those related to the restoration and surrounding tissues. These data were obtained at several time points up to a 1-year follow-up. Results Thirty-four patients were included in the study, 18 assigned to the test group. No differences at implant placement were detected for tissue thickness, keratinized mucosa, nor any other clinical or radiological variable. At the time of impressions, tissue was thinner in the test group (2.30 (0.46) versus 2.78 (0.66) mm, test versus control, respectively; p = .012) so shorter abutments were used in this group. Regardless, no significant changes in marginal bone level were detected neither within group along time nor between groups. The average MBL at the 1-year follow-up was −0.15 (0.32) versus −0.22 (0.37) (p = .443) (test versus control, respectively). None of the clinical or radiological variables evaluated had a determinant influence on the MBL at any visit nor group. Conclusion The use of implants with a multi-phosphonate coated surface for early loading offers successful radiographical outcomes 1 year after loading. MBL over time was not affected by taking the impressions 4 or 8 weeks after implant placement and loading them 2 weeks later.
