Abstract
Tras la pérdida dentaria se producen alteraciones dimensionales de las crestas óseas residuales, con pérdida de la disponibilidad ósea para colocar implantes dentales, lo que requiere procedimientos quirúrgicos regenerativos. Igualmente, las lesiones óseas resultantes de la peri-implantitis pueden requerir intervenciones regenerativas. Aunque el análisis histológico en estudios experimentales in vivo es el “gold standard” para evaluar la cicatrización de los tejidos, los avances en la tecnología digital nos permiten en la actualidad obtener información de los cambios de volumen y contorno, de ambos tejidos blandos y duros durante los procesos de cicatrización, de una modo menos invasivo y más preciso. Objetivos. Evaluar el comportamiento de los tejidos blandos tras técnicas de regeneración ósea horizontal, mediante dos diferentes combinaciones de biomateriales (estudio 1); evaluar el comportamiento de ambos tejidos blandos y duros tras técnicas de regeneración ósea horizontal, mediante dos membranas barrera diferentes (estudio 2); evaluar el comportamiento de ambos tejidos blandos y duros en un modelo de peri-implantitis experimental, con dos superficies diferentes de implantes (estudio 3)...
Tooth loss causes dimensional alterations of the alveolar process, which result in hard tissue deficiencies that could difficult the placement of dental implants. In these situations, lateral bone augmentation is used to achieve the appropriate alveolar bone crest. Similarly, bone defects resulting from peri-implantitis may require regenerative interventions. Histological analysis in experimental studies is considered the gold standard to assess tissues healing, however the improvement in digital technology could allow us to obtain more information about volumetric and contour changes of both soft and hard tissues during healing processes, in a less invasive and more precise way. Objective. To evaluate the contour linear changes of soft tissues after lateral bone regeneration, using two different combinations of biomaterials (study 1); evaluate the volumetric and contour linear changes of both soft and hard tissues after lateral bone regeneration, using two different barrier membranes (study 2); evaluate the volumetric and contour linear changes of both soft and hard tissues in an experimental peri-implantitis model, with two different implant surfaces (study 3)...
