Peri-implant soft tissue augmentation with a porcine collagen matrix.

Yuri Castro, Silvana Grados, Sixto Grados

Abstract


A good amount and width of keratinized tissue around implants has been associated with better health periimplant, less bone loss and improved aesthetics. The purpose of this case was to evaluate a new porcine xenograft (collagen matrix) when used as an interpositional graft to increase the thickness of the peri-implant mucosa. Few studies using the collagen matrix as a substitute for subepithelial connective graft around implants are. The case involved an implant clinical at level of teeth 15 during placement of scar took the opportunity to swell the peri-implant mucosa with the collagen matrix. An increase in thickness of 1.5 mm while maintaining the amount of keratinized mucosa 4mm was obtained. We conclude that the collagen matrix of porcine origin is a good alternative to increase the thickness of the peri-implant mucosa and reduce morbidity, be easy to handle and easy to suture.

Keywords: Aesthetics, dental implant, peri-implant tissue, peri-implant mucosa thickness, peri-implant health.

Aumento de tejido blando periimplantario con matriz de colágeno porcino. Reporte de caso clínico

Una buena cantidad y grosor de tejido queratinizado alrededor de implantes ha sido asociado con una mejor salud periimplantaria, menos pérdida ósea y una mejora en la estética. El propósito de este caso clínico fue evaluar un nuevo xenoinjerto de origen porcino (matriz de colágeno) al ser utilizada como un injerto interposicional para aumentar el grosor de la mucosa periimplantaria. Son pocos los estudios que utilizan la matriz de colágeno como sustituto del injerto conectivo subepitelial alrededor de implantes. El caso clínico incluyó un implante a nivel de la pieza 15, en el cual durante la colocación del pilar de cicatrización se aprovechó para engrosar la mucosa periimplantaria utilizando una matriz de colágeno. Se obtuvo un aumento de grosor de 1,5mm manteniéndose la cantidad de mucosa queratinizada de 4mm. Se concluyó que la matriz de colágeno de origen porcino es una buena alternativa para aumentar el grosor de la mucosa periimplantaria, además de reducir la morbilidad, ser de fácil manejo y de fácil sutura.

Palabras clave: Estética, implante dental, tejido periimplantario, grosor mucosa periimplantaria, salud periimplantaria.
