Clinical efficacy of a xenogeneic collagen matrix in augmenting keratinized mucosa around implants: a randomized controlled prospective clinical trial

Abstract

These results prove that this new CM was as effective and predictable as the CTG for attaining a band of keratinized tissue.

Palatal wound healing using a xenogeneic collagen matrix – histological outcomes of a randomized controlled clinical trial

“…Namely collagen matrices made of collagen type I and III have been the field of interest in recent years. These substitute materials were evaluated in preclinical and clinical studies for gain of keratinized tissue around teeth and implants, for recession coverage, for ridge preservation and even for soft tissue volume gain (Schmitt et al, 2015, Rotundo and Pini-Prato, 2012, Nevins et al, 2011, Lorenzo et al, 2012, Jung et al, 2013b, Thoma et al, 2010, Cardaropoli et al, 2012. The currently available evidence suggests that these collagen matrices can be safely used, integrate well into surrounding tissue, increase tissue thickness and increase the width of keratinized tissue to an extent close to the gold standard, the autogenous tissue (Sanz et al, 2009, Thoma et al, 2012, Jung et al, 2011.…”

Matriz colágena suína no recobrimento radicular e aumento da faixa de gengiva ceratinizada: revisão sistemática da literatura

“…Tanto o tratamento convencional (enxertos autógenos de tecido mole e DCR) quanto o uso da MC reduziram significativamente a recessão gengival e aumentaram significativamente a faixa de GC [20][21][22][23][24][25][26] .…”

“…Observou-se, além disso, aumento significante da faixa de GC [20][21][22][23][24][25][26] , dimunuição da largura da recessão 20,24 e aumento da espessura gengival [20][21][22] , ainda que resultados diferentes tenham sido relatados [20][21][22]24 . O tratamento por meio de MC resultou em estética satisfatória e diminuiu a sintomatologia dolorosa pós-operatória [20][21][22][23][24][25][26] , comparativamente aos enxertos autógenos livres de tecido mole, os quais requerem a confecção de dois leitos cirúrgicos (sítios recepetor e doador) 1 .…”

“…De forma geral, embora tivessem recebido alguma forma de apoio financeiro da empresa fabricante do material, a maioria dos estudos [20][21][22][23][24][25] incluídos nessa revisão sistemática apresentou baixo risco de viés (ou bias), visto que houve cegamento simples dos participantes (examinadores) e randomização da amostra gerada por programas de computador ou uso de envelopes fechados contendo os códigos dos procedimentos a serem realizados.…”

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

“…Valderhaug says its scarcity increases swelling and subsequent loss of insertion 2 . The amount of soft tissue surrounding the implants is also a matter of controversy 3 . Grusovin conducted a review in which there was not sufficient evidence about the influence of peri-implant mucosa width on implant survival 4 .…”
