Is the Bacterial Cellulose Membrane Feasible for Osteopromotive Property?

Guided bone regeneration was studied to establish protocols and develop new biomaterials that revealed satisfactory results. The present study aimed to comparatively evaluate the efficiency of the bacterial cellulose membrane (Nanoskin) and collagen membrane Bio-Gide in the bone repair of 8-mm critical size defects in rat calvaria. Seventy-two adult male rats were divided into three experimental groups (n = 24): the CG-membrane-free control group (only blood clot, negative control), BG-porcine collagen membrane group (Bio-Guide, positive control), and BC-bacterial cellulose membrane group (experimental group).

Conservative Management of Central Cemento-Ossifying Fibroma.

Central cemento-ossifying fibroma is characterized by the combined production of osteoid and cementoid tissue. Radiographically, this lesion is presented as an outlined cortical and variable radiopaque spots, also can be present complete radiolucent or different degrees of radiopacity. The recommended treatment is curettage or enucleation, and the recurrence rate is less than 5%.

Failure of Maxillary Reconstruction With Freeze-Dried Bone Allograft.

Bone reconstruction to reestablish bone width and height is required in case of bone atrophy. A 45-year-old white woman was referred to the oral clinical surgery of Aracatuba Dental School, University Estadual Paulista-UNESP, in 2013 with the main complain of bone exposure at the superior right site of the maxilla after 1-year reconstruction with bone block allograft. Bone block was removed besides the dental implant next to the bone allograft.
