DBM Abbreviation for Demineralized bone matrix.

Debridement Removal of inflamed, devitalized, or contaminated tissue or foreign material from or adjacent to a lesion.

Deciduous dentition See: Dentition, primary.

Decortication Intraoperative preparation of the recipient bone bed by making numerous small perforations into the cortex to induce bleeding from the marrow cavity. This technique is routinely used in combination with onlay block grafts or guided bone regeneration (GBR) procedures. See also: Bone preparation.

Defect Genetic or acquired deficiency of an anatomic structure (ie, bone or soft tissue) required for normal function or esthetics. See also: Critical-sized defect.

Definitive cast See: Master impression.

Definitive prosthesis Orodental or maxillofacial restoration designed and fabricated for long-term use. This term is preferable to final prosthesis, since no artificial replacement can be considered permanent.1

Dehiscence Buccal or lingual bone defect in the crestal area extending apically at an implant. See also: Fenestration; Wound dehiscence.

Delayed implant placement See: Late implant placement.

Delayed loading Placing an implant into function or a load-bearing situation following an extended period of healing after the initial placement.

Demineralized bone matrix (DBM) Bone matrix, usually allogeneic in origin, that may induce bone formation via release of growth factors and bone morphogenetic proteins (BMPs) from the matrix, occasionally after osteoclastic breakdown. Osteoinductive potential may vary, dependent on method of preparation and degree of demineralization.

Demineralized freeze-dried bone allograft (DFDBA) By demineralization, the mineral phase of freeze-dried bone allografts is partly or completely removed so that the collagen and non-collagenous matrix is exposed, thereby making growth factors available.

Dental cast See: Cast.

Dental plaster See: Calcium sulfate; Dental stone.

Dental stone Denser alpha-hemihydrate form of calcium sulfate, stronger than the beta form. It is commonly used for dental casts involved in the fabrication of denture prostheses. An even denser, stronger die stone is used to create a positive likeness of a prepared tooth for the fabrication of crown restorations.1 See also: Calcium sulfate.

Dentition Collective teeth in the dental arches.2,3

Artificial d. Imitation replacement for natural teeth.

Natural d. Normal living teeth that erupt into the oral cavity.

Permanent d. Natural teeth that succeed the primary teeth as the primary teeth are shed. Called also succedaneous dentition.

Primary d. Earliest natural teeth that erupt into the dental arches of the oral cavity normally during childhood. Called also deciduous dentition.

Dentoalveolar distraction See: Alveolar distraction osteogenesis.

Dentofacial orthopedics See: Orthodontics.

Denture Artificial replacement for natural teeth and related structures. A conventional or traditional denture is a generic phrase for the long-standing concept of a dental prosthesis, most commonly a removable prosthesis.2 See also: Prosthesis.

Denture prosthesis A generic term for the longstanding concept of artificial replacement of natural teeth and related structures, most commonly a removable device. The term is also used to denote its distinctness from an implant-supported or a craniofacial prosthesis.1,2

De-osseointegration State in which prior osseointegration is subsequently lost.

Depassivation Removal or loss of an oxide layer from the surface of a metal.

Deproteinized bovine bone material See: Bovine-derived anorganic bone matrix.

Depth gauge Gauge for measuring the depth of grooves or holes or other concavities. In implant dentistry, used to measure the depth of the osteotomy during implant site preparation.

Dermal graft Skin graft made with a thin split-thickness graft of dermis.4 See also: Acellular dermal allograft.

Developmental anomaly Aberration in the normal sequence of events associated with growth and development. This process could result over time in distortion of the face and jaws, abnormality of tooth formation or position, and irregularity of function.2,5

Device Apparatus, instrumentation, or machine designed to carry out a specific purpose.

DFDBA Abbreviation for Demineralized freeze-dried bone allograft.
