A series of poly(L-lactide-co-ε-caprolactone)/polyethylene oxide/hydroxyapaite (PLCL/PEO/HA) composite fibrous membranes were prepared by elecrospinning technology for guided bone regeneration. The morphology, water permeability and mechanical properties of the membranes were investigated. The HA nanocrystals can be well distributed in the PLCL/PEO matrix. And the diameter of composite nanofiber is larger than that of pure PLCL. The fibers with uniform size and large diameter were obtained when the contents of PEO and HA were 0.4% and 0.03%, respectively. In this condition, the obtained membrane presents the best water permeability. Furthermore, the nanofibrous membrane with largest tensile strength was obtained when the contents of PEO and HA were 0.5% and 0.03%, respectively.

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.
