Particular anorganic bovine bone substitute with a calcium‐deficient carbonate hydroxyapatite having a crystal size of approximately 10 nm. All proteins are removed from the bovine xenograft via various chemical and physical processes. Its porous structure, like normal bone, is osteoconductive but resistant to resorption, although osteoclasts are identified in lacunae on the surfaces. The surface…

The action of the alveolar mucosa aided by muscles and tissues proximal to the borders of the denture. Usually recorded during border molding to fashion the denture edges.  

The physical contact established by the alveolar mucosa to drape the molded borders of an oral removable prosthesis in an attempt to create negative pressure that aids in the retention of the prosthesis and the prevention of the ingress of fluids, air, and food into the intaglio surface. The edge of a denture that contacts…

When observed in a designated plane, it is the mandibular movements at the boundaries permitted by anatomic structures. The movements are reproducible and unique for each individual. All mandibular movements are determined by the parameters of the border movements.  

Alteration in the morphologic features of bone.  

Hollow, cylindrical cutting bur of various diameters used to harvest cylindrical bone blocks.  

Device connected to the surgical suction to collect fine bone slurry within the surgical field during the drilling of bone or harvest of a bone block for alveolar ridge augmentation or maxillary sinus floor elevation. Collected bone can be added to the particulate graft.  

Nonviable biomaterial for reconstruction of bone, producing only a scaffold for formation of new bone. Supports the inherent potential for bone regeneration. It may be resorbable or remain in an unchanged version at the site of implantation. It also may assist in preservation of contour of an osseous reconstruction.  

Represents the end result of a remodeling cycle of mature bone. In cortical bone, it constitutes a Haversian system after a cortical remodeling unit has taken place. In cancellous bone, it is a wall or packet. See: Bone remodeling unit (BRU), Basic multicellular unit (BMU).
