Tissue changes of extraction sockets in humans: a comparison of spontaneous healing vs. ridge preservation with secondary soft tissue healing

Abstract

This study clearly points out that an alveolar ridge preservation technique performed with collagenated porcine bone and a resorbable membrane--according to the procedure reported in this study--was able to limit the contour changes after tooth extraction. Finally, the test sites showed a better preservation of facial keratinized tissue when compared to control sites; grafted sites allowed the placement of longer and wider implants when compared to implants inserted in non-grafted sites.

The Effects of the Combined Use of Platelet-Rich Plasma and Xenograft on Alveolar Socket Healing

“…After six weeks, bone trabeculae appeared to be in an advanced phase of mineralization; the thickening process of the trabeculae is associated with movable osteoblastic laminae (dynamic osteogenesis). The bone deposition that will be completed in 4-6 months [29][30][31]. The main consequence of tooth extraction is a significant resorption of the bony walls of the alveolar socket.…”

Regional 3D superimposition to assess temporomandibular joint condylar morphology

“…32,45,47,56 The artefacts generated from restorative dentistry, movement of the patient, partial volume averaging, incorrect selection of kVp/mA and threshold settings can affect the volume image and segmentation. 48,[57][58][59][60] In the absence of artefacts, Luu et al 45 clearly described that when defining the true boundary of an object, at best, the line for this boundary will cross directly through the centre of a voxel. At worst, when attempting to select a boundary that truly goes between voxels, one is forced to select the centre of one of the surrounding voxels.…”

Avaliação comparativa dimensional longitudinal do rebordo alveolar pós exodontia, com modalidades cirúrgicas distintas: convencional x com dispositivo minimamente traumático

“…O grupo experimental sofreu diminuição em aproximadamente 19% da espessura do topo do rebordo, 12% da espessura do centro do rebordo, 28% da área cervical do rebordo e 26% da área total do rebordo. A magnitude desses dados é suportada pela literatura (CAMARGO et al, 2000;SCHROPP et al, 2003;VAN DER WEIJDEN;DELL'ACQUA;SLOT, 2009;BARONE et al, 2012;TAN et al, 2012 …”

“…Dessa forma, tem-se uma evidência científica mais clara, já que animais como cães ou ratos podem trazer diferenças anatômicas, fisiológicas e metabólicas (IASELLA et al, 2003;SCHROPP et al, 2003; MOYA-VILLAESCUSA; SÁNCHEZ-PÉREZ, 2010;BARONE et al, 2012;LAMBERT et al, 2012;FARMER;DARBY, 2013;MUSKA et al, 2013;THALMAIR, 2013;LI, WANG, 2014;KARACA et al, 2015).…”

“…Variados estudos compreendidos em revisões sistemáticas endossam a necessidade de uma randomização para distribuição dos indivíduos entre os grupos teste e controle, da definição de critérios de inclusão e exclusão e da real necessidade de extração dos dentes que foram submetidos à exodontia (VAN DER WEIJDEN; DELL'ACQUA; SLOT, 2009;BARONE et al, 2012;LAMBERT et al, 2012;MORJARIA;PALMER, 2012;HORVÁTH et al, 2013). Todas essas observações foram seguidas o mais fielmente possível no presente trabalho.…”
