Guided bone regeneration (GBR) technique is most commonly used to treat alveolar bone defect. Polylactic acid (PLA) attracts much attention to utilize as a GBR membrane because it has relatively high mechanical strength and biodegradability. However, randomized controlled trials of PLA as a GBR membrane in animals were rare. The aim of this work is to observe the efficacy of polylactic acid membrane in guiding bone regeneration in Beagle canine alveolar bone defect restoration and to compare efficacy with the collagen membrane, providing an experimental basis for further clinical use of the polylactic acid membrane. The tests of physical and chemical properties showed that the PLA membrane has well mechanical strength to maintenance the space for the new bone, and has proper aperture for the attachment of osteoblasts. Through X-ray and histopathological examination of the different time points, the bone grafting material covered with PLA membrane can form similar mature bone compared to collagen membrane ones. Meanwhile, biodegradable speed of the PLA membrane was slower. Thus, this study showed that polylactic acid membrane as synthetic biodegradable polymer was reliably effective in guiding bone regeneration of alveolar bone defects, showed the favorable osteogenic capability and forecasts well applications in bone augmentation.

Membrane fixation in guided bone regeneration (GBR) has been traditionally achieved using resorbable pins, titanium tacks or miniscrews. However, these techniques are marredwith a number of clinical challenges. This article presents the “SauFRa” technique, a novel technique for stabilization of resorbable membranes in both, single as well as multiple implant sites while avoiding the shortcomings of other suturing techniques described in literature. Furthermore, the technique also eliminates the possibility of complications observed when using resorbable pins, titanium tacks or miniscrews, such as damage to adjacent roots during insertion. The authors’ employed this technique in 89 patients (51 male and 35 female) and found no complications like tissue dehiscence, infection or graft migration.

Resumo O osso é um tecido conjuntivo especializado, vascularizado e dinâmico que se modifica ao longo do organismo. Quando lesado, possui uma capacidade única de regeneração e reparação sem a presença de cicatrizes, mas em algumas situações devido tamanho do defeito ósseo não se regenera por completo. Assim, se faz necessária a realização de procedimentos de regeneração óssea guiada. Para isso, o implantodontista deve conhecer as bases biológicas da regeneração óssea guiada alveolar e suas indicações. Nesta revisão foram abordadas indicações, vantagens e tipos de biomateriais utilizados para preenchimento do alvéolo dentário imediatamente após a extração dentária sempre que o objetivo for à reabilitação através da instalação de implantes. Mesmo este, biomateriais, apresentando inúmeras qualidades, estudos ainda devem ser feitos a fim de obter a cada dia, um material sintético compatível com o tecido ósseo perdido em quantidades adequadas sem necessitar de cirurgias extra-bucais.ABSTRACT Bone is a specialized vascularized connective tissue that dynamic changes throughout the body. When injured, it has a unique ability to regenerate and repair without the presence of scars, but in some situations due to size of the bone defect does not regenerate completely. Thus, it is necessary to perform guided bone regeneration procedures. For this, the implant dentistry must know the biological bases of alveolar guided bone regeneration and its indications. In this review were addressed indications, advantages and types of biomaterials used for filling the tooth socket immediately after the tooth extraction whenever the goal is rehabilitation through implants installation. Even this, biomaterials, having several qualities, further studies must be done to obtain each day, a synthetic material compatible with the bone tissue lost in proper amounts without the need of extra-oral surgery.
