Abutment, custom
A custom-made post attached to the superior part of the metal dental implant that protrudes through the gingival tissues and onto which the restoration is fitted; either machined or cast, and used in situations where prefabricated abutments cannot be used.

Abutment, prefabricated
A machine-manufactured post attached to the superior part of a dental implant that protrudes through the gingival tissues and onto which a restoration is fitted.

Abutment, UCLA
A cast component used to create a custom abutment for prosthesis. Also known as a castable abutment.

It is defined as the dynamic contact relationship between the occlusal surfaces of the teeth during function.

A fixed dental restoration (a fixed dental prosthesis) used to replace a missing tooth (or several teeth) by joining an artificial tooth permanently to adjacent teeth or dental implants.

A solid Zirconia that indicated for crowns, bridges, implants, inlays and onlays, screw-retained implant crowns and full-arch implant prostheses. It is an esthetic alternative to PFM metal occlusal/lingual or full-cast restorations.

A condition in which you grind, gnash or clench your teeth excessively, often during sleep.

A destructive process causing decalcification of the tooth enamel and leading to continued destruction of enamel and dentin, and cavitation of the tooth.

Dental cements are hard, brittle materials formed by mixing powder and liquid together. They are either resin cements or acid-base cements. In the latter the powder is a basic metal oxide or silicate and the liquid is acidic.

Centric occlusion
The position of mandible when the relationship of the opposing occlusal surface that provides the maximum planned contact and / or inter-cuspation

A dental material that is usually used for tooth-colored fillings and hardens with a curing light. Composite material contains acrylic and glass particles, but no mercury.

Concepts of Occlusion
Occlusion is a factor that is common to all branches of dentistry. The study of occlusion and its relationship to function of the masticatory system has been a topic of interest in dentistry since many years. One of the chief aims of preventive and restorative dentistry has been to maintain an occlusion that will function in harmony with the other components of the masticatory mechanism, thereby preserving their health and at the same time providing the optimum, if not maximum masticatory function.

A tooth-shaped “cap” that is placed over a tooth — to cover the tooth to restore its shape and size, strength, and improve its appearance. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.

Crown preparation: This is the design of the tooth after it has been shaved down to allow room for a crown. The preparation design depends on the material that the crown will be made from, previous fillings, fractures, and root canal therapy performed on the tooth while trying to maintain enough tooth structure for the crown to adhere.

 These are the raised or pointy parts of a crown that are the primary tools for tearing and chewing food. When a cusp has been damaged from a cavity or fracture, the tooth needs a crown to prevent further damage.

Dental Implant
A surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, facial prosthesis or to act as an orthodontic anchor.

Also Known As: Endosseous implant or fixture

Dental Laboratory
Dental laboratories manufacture or customize a variety of products to assist in the provision of oral health care by a licensed dentist. These products include crowns, bridges, dentures and other dental products.

Dental veneer
 Porcelain veneers are partial crowns that cover only the front and biting edge of teeth. These all-ceramic restorations are usually placed on front teeth to change the color or shape of teeth or add symmetry and balance to a smile. Since they are sometimes placed on crooked teeth, treatment with veneers has sometimes been referred to as "instant orthodontics."

Prosthetic devices constructed to replace missing teeth; they are supported by the surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable (removable partial denture or complete denture). However, there are many different denture designs, some which rely on bonding or clasping onto teeth or dental implants (fixed prosthodontics).

Dental specialist that has completed 4 years of dental school along with an additional 2 or more years of specialty training in endodontics (root canals).

Eccentric occlusion
Contacting of teeth or occluding surface when the jaws are in any relation other than centric occlusion

Excessive wear of teeth
 If a person has a habit of grinding their teeth, the teeth will become shorter over time. The teeth can also wear away due to acid erosion caused by gastrointestinal acid reflux (GERD), bulimia, or an acidic diet. Sometimes, the enamel will wear away completely, leaving small, soft teeth. Over time, the bite can collapse and the only way of restoring the teeth properly is by increasing the bite and covering the teeth with crowns.

A removable partial denture is for a partially edentulous dental patient who desires to have replacement teeth for functional or aesthetic reasons, and who cannot have a bridge for any number of reasons.

Inflammation of the gums in response to bacterial biofilms (also called plaque) adherent to tooth surfaces.

High noble alloys (Precious metal)
A group of alloys with a composition that is over 60% noble metal (gold, palladium and/or platinum), of which more than 40% must be gold.

Immediate Denture
A complete or partial denture constructed for insertion immediately following the removal of natural teeth.

Also Known As: Practice Denture

 This is the edge of the crown that meets the prepared surface of the tooth. This needs to be smooth with no gaps or ledges.

Noble alloys (Semiprecious metal)
These alloys have at least 25% noble metal content.

Non-noble (Nonprecious metal)
These alloys are also referred to as base metals. Their noble metal content is less than 25% (they may have none). They often contain large percentages of nickel, cobalt, chromium or beryllium. B&B Dental Tech predominately uses Cobalt Chromium (CoCr) with NO nickel or beryllium.

Act or process of closure or of being closed or shut off. The static relationship between the incising or masticating surfaces of the maxillary or mandibular teeth or tooth analogue.

Oral Surgery
The branch of dentistry or of surgery dealing with the surgical treatment or repair of various conditions of the mouth or jaws.

Osseo integration
The firm anchoring of a surgical implant (as in dentistry or in bone surgery) by the growth of bone around it without fibrous tissue formation at the interface.

Partial crown/onlay
This is a crown that only covers some of the cusps of the tooth, but not all of them. This restoration is chosen as a conservative measure to preserve as much tooth structure as possible. When conditions allow, this is the preferred type of crown restoration.

A dentist who specializes in the prevention, diagnosis, and treatment of periodontal (gum) disease, and in the placement of dental implants.

Porcelain-fused-to-metal dental crowns (PFMs) have a metal shell on which is fused a veneer of porcelain in a high heat oven. The metal provides strong compression and tensile strength, and the porcelain gives the crown a white tooth-like appearance, suitable for front teeth restorations.

Post and Core
A type of dental restoration that is utilized when there is inadequate tooth structure remaining to support a traditional restoration. A small rod, usually metal, is inserted into the root space (root canal) of the tooth and protrudes from the root a couple of millimeters. This rod is referred to as a post. The post is then used to hold a filling, or core, in place. Without this post there would not have been enough tooth structure remaining to hold the filling required. B&B Dental Tech can cast custom posts as required.

Prosthetic implant abutment
In Dentistry, an abutment is a connecting element. Abutments can be made from a variety of materials, such as titanium, surgical stainless steel and gold. More modern abutments are now also made from zirconia, to better complement the aesthetics of a dental implant restoration. An abutment is not necessarily parallel to the long axis of the implant. It is utilized when the implant is at a different inclination in relation to the proposed prosthesis. Most crowns and fixed partial dentures have a cemented or screw-retained fixation on the abutment.

Sliding occlusion
is the contacting of teeth in motion. Sliding occlusion occurs when the occlusal surface of the teeth make contact when the mandible is moving.

Temporary Crown
A temporary (short-term) crown used in dentistry. Like other interim restorations, it serves until a final (definitive) restoration can be inserted.

Temporomandibular Joint Disorder
A disorder of the temporomandibular joint(s) that causes pain, usually in front of the ear(s), sometimes in the form of a headache.

Also Known As: TMJ

A white dental ceramic used to fabricate dental prosthetics
