Regeneración ósea vertical en sector anterior mediante técnica de tent-pole

Abstract

Vertical ridge bone loss is still a challenge due to anatomical limitations and technical difficulties when it comes to implant planning. Through the decades, different techniques and grafts have been suggested to treat deficient alveolar ridge. Implantology and guided bone regeneration are increasingly predictable thanks to some advances in biomaterials and the development of new techniques. However, vertical ridge augmentations remains to be a challenge due to the complexity of the soft and hard tissue management. During the years, this situation has been managed through different surgical techniques and the use of different types of biomaterials, but long term optimal results regarding stability has not been achieved. Non-resorbable membranes has a high exposure risk, so it is necessary to remove them during the reentry. Resorbable membranes have shown a better biocompatibility and support of the bone growth below. However, its lack of rigidity can lead to a reduction of the bone volume gain. Therefore, tent pole technique, which combines a resorbable collagen membrane and screws, represents an effective approach which offer an easy manipulation and low complication rates.
