La diferencia principal entre los implantes dentales tardíos y los implantes dentales post exodoncia es el tiempo en que se hace la carga al implante.
Los implantes dentales post exodoncia son aquellos donde se hace carga inmediata del implante dental mientras que los tardíos son aquellos que después de meses de la exodoncia se hace la carga del implante para permitir la cicatrización de los tejidos blandos.
Algunos estudios evaluaron cuál es el mejor momento para colocar los implantes. Un estudio evaluó si el injerto óseo es ventajoso en la colocación del implante y dos estudios evaluaron cuáles son las mejores técnicas de injerto.
Interventions for replacing missing teeth: dental implants in fresh extraction sockets (immediate, immediate?delayed and delayed implants)
'Immediate' implants are placed in dental sockets just after tooth extraction. 'Immediate?delayed' implants are those implants inserted after weeks up to about a couple of months to allow for soft tissue healing. 'Delayed' implants are those placed thereafter in partially or completely healed bone. The potential advantages of immediate implants are that treatment time can be shortened and that bone volumes might be partially maintained thus possibly providing good aesthetic results. The potential disadvantages are an increased risk of infection and failures. After implant placement in postextractive sites, gaps can be present between the implant and the bony walls. It is possible to fill these gaps and to augment bone simultaneously to implant placement. There are many techniques to achieve this but it is unclear when augmentation is needed and which could be the best augmentation technique.
