Las perforaciones corticales, penetraciones intramedulares o decorticaciones se realizan a menudocomo parte del procedimiento de regeneración ósea guiada (ROG). Su sustento biológico se basa en quemejorarían la angiogénesis y proporcionarían una vía hacia el hueso esponjoso rico en vasos sanguíneos.También se consideran como un “noxious stimuli” (estímulo nocivo) que iniciaría el fenómeno regionalacelerado con una respuesta local exuberante facilitando la cicatrización ósea normal. Además, mejoraríanla unión o enlace físico entre el injerto óseo y el lecho receptor asegurando estabilidad y fusión de losbloques óseos. Sin embargo, se nos presentan algunas interrogantes relacionadas a su fundamento, a lostérminos que las describen, a los tamaños, a su cantidad y disposición, al instrumental adecuado pararealizarlas y al confort del paciente.

In recent years, the percentage of dental implant placement has increased, and the presence of adverse events and complications are not uncommon. The vast majority of recommendations for reducing complications associated with dental implant placement are analyzed from the point of view of their direct causes, evaluating the technique and/or the individual, but not the system as a whole, being this the actual etiology of complications. The inclusion of human factors and situation awareness has recently gained increasing importance in oral implantology complications and has allowed global analysis of both the individual and the environment, providing solutions based on prevention. However, knowledge and use of these aspects in oral implantology are still in the process of popularization, and therefore, the objective of this article was to describe the human factors involved and situation a...

Implant-supported restorations have shown remarkable progress in recent years and have demonstrated high sur vival rates of up to 95% with well-documented functional and esthetic results [1, 2]. Classically, implant-supported restorations can be cement-retained or screw-retained. Al though both methods have potential uses, the ideal option has yet to be established, and the selection depends on retrievability and esthetic factors [3]. Depending on the retention method, the success of the implant rehabilitation is not free of complications and re quires dynamic equilibrium between implant osseointe gration and technical and biological factors. However, based on current findings, the main complications of dental im plants are produced by biological factors [4, 5].
