A

Abrasion - Grinding or wearing away. (See Bruxism)

Abscess - A localized area of inflammation containing pus.

Abutment - A tooth or implant that retains or supports a fixed bridge or a removable prosthesis. The abutments may be crowns, onlays, or inlays. Sometimes referred to as a retainer.

Acid-Etch Technique - In restorative dentistry, a method of etching the tooth enamel with an acid to provide an adhesion of the composite filling material to the tooth surface.

Administrative Services Only (ASO) - An arrangement under which a third party charges a fee to process claims and handle paperwork for a self-funded group. The third party frequently performs all insurance company services (actuarial, underwriting, plan materials and descriptions, claims processing, etc.) except for the assumption of risk and the cost of paying claims. (Compare to CSO)

Aesthetics - In dentistry, refers to procedures that have a particularly evident cosmetic purpose. For example, bleaching or tooth-whitening, composite restorations (white fillings), porcelain prosthetics and veneers.

Align - To move teeth into position for a proper line of occlusion (bite).

Allowance Method - Also called a Claim Allowance Option. The method used on an eligible procedure to determine the maximum covered dollar amount considered. Allowance Methods are an integral part of a plan design and are defined in the group policy contracts and in each member certificate booklet. Some examples of Allowance Methods:

  1. Usual and Customary (U&C)
  2. Scheduled Allowances (SCU)
  3. Maximum Allowable Charge on PPO plan (MAC)
  4. Maximum Allowable Benefit (MAB)
  5. Maximum Procedure Allowance (MPA)

Please refer to your certificate booklet to see what Allowance Method design is used for your plan.

Alloy - A mixture of two or more metals, as in silver amalgam fillings.

Alternate Benefit Clause - A provision in a dental plan that allows the third-party payer (insurance company) to determine the benefit payable based on an alternative procedure than the one provided or proposed. This is not intended to determine treatment but to establish benefits payable.

This provision is designed into many dental plans because there are often alternate methods of treatment for the same condition in dentistry. In some cases there may be a less expensive service that is customarily performed for the given situation. In such cases, a more expensive alternate procedure may be preferred by the dental provider or the patient, or may have a cosmetic element involved. For example, a molar tooth that is being restored with a composite (white) filling will be reimbursed at the alternate benefit level of an amalgam (silver) filling.

Alveolus - In dentistry, the bony socket for the root of the tooth. A small pit or hollow. The plural form is alveoli. The root sockets in each arch are supported and surrounded by a bone structure called the alveolar process. The line or junction where the root sockets meet the surrounding bone structure is the alveolar ridge. Surgical removal, contouring or restructuring of the alveolar process is called alveoplasty.

Alveoplasty - Surgical removal or correction of the alveolar process to restore a normal contour. It can range from surgical removal (alveolectomy) in conjunction with extractions to necessary reconstruction of the ridge in preparation for dentures. (See Alveolus)

If a member elects to enroll after his/her initial 31 days of eligibility, even during an Annual Enrollment, there is usually a "Late Entrant" penalty imposed. Annual Enrollment differs from Open Enrollment. Questions about enrollment and Late Entrant provisions should be addressed with your Benefit Administrator. (See Open Enrollment and Late Entrant)

Anterior - In the front. With reference to teeth, the anteriors are incisors and cuspids. (See Mouth Diagram)

Apex - The anatomic end of the tooth root. (See Tooth Diagram)

Apexification - Normally performed on a young patient where the apex of a tooth is incompletely formed. The pulp is removed and the apex treated with calcium hydroxide. This stimulates the growth of cementum, which promotes apical closure. Root canal therapy would usually be performed at a later time.

Benefit credit is established when the benefits of both carriers combine to equal more than the actual expenses incurred. When a later claim is received for an eligible procedure that is not paid in full between the two carriers, the amount in benefit credit will be released to pay the difference. When benefit credit is earned or paid, it will be noted on your Benefit Statement. (See Coordination of Benefits)

Benefit Period - The period of time defined in the policy that certain records are kept or individual benefits are paid. Typically, a Benefit Period determines when the yearly maximum and the yearly deductible renew. The beginning date may vary depending on the plan.

Bite Guard - See Night Guard and Bruxism.

Bitewings - Dental X-ray films that normally show approximately the crown portions of both the upper and lower teeth on the same film.

Bleaching - A technique used to restore a discolored tooth to its natural color.

Bridgework - (Fixed) Restores the continuity of the dentition by replacing missing natural teeth with artificial teeth (pontics) which are attached to, and supported by, abutments or retainers. The abutments may be crowns, onlays or inlays. The pontics are usually supported between two abutments; however, a cantilevered bridge has abutments on just one side of the pontic. (Removable) A partial denture retained by attachments permitting its removal. It is generally a one-piece metal casting, with denture teeth to replace missing natural teeth. It is held in place by clasps. Units of removable bridges include the teeth and the clasps.

Bruxism - A clenching or grinding of the teeth, associated with a forceful jaw movement, usually during sleep. It is a habit frequently related to emotional stress, anxiety, fatigue, or bite interference. Bruxism may grind away at and/or fracture teeth. Untreated, the condition may affect a person's entire bite (occlusion) causing temporomandibular joint (TMJ) problems and/or periodontal disease. Dental plans rarely cover the treatment of Bruxism and TMJ because the underlying cause is typically a condition other than dental decay. Coverage through one's medical insurance should also be investigated. (See TMD/TMJ)

Bruxism Appliance - See Night Guard and Bruxism.

Buccal - The surface of the tooth toward the cheek. (See Mouth Diagram)

C

Cafeteria Plan - A type of benefit plan where enrollees select from a list of nontaxable benefit options. The insured members' premium payments are funded with pre-tax employee contributions. Available plan options may include, but are not limited to, medical, dental, and eye care. The tax code allowing Cafeteria Plans restricts enrollment and cancellation to one opportunity each year plus certain qualifying events. Cafeteria Plans are also called Flex or Section 125 plans.

Calendar Year - The period of time from January 1 of any year through December 31 of the same year. On a Calendar Year plan, the benefit Period for someone who becomes effective on a date other than January 1 is their effective date through December 31 of the same year, then January 1 to December 31 subsequently. (See Benefit Period)

Calendar Year Maximum - A plan's payment limit in actual dollars toward the services performed during a particular Calendar Year. unless otherwise stated in policy, the limit applies to all payable procedures including routine exams and cleanings. (See Calendar Year)

Canal - A tubular passage or channel. A root canal is the space within the root of a tooth that contains the pulp tissue.

CHD - Abbreviation for child found on some dental Benefit Statements.

Claim - A statement listing services rendered, the dates of services, and an itemization of costs. Includes a statement signed by the beneficiary and treating dentist that services have been rendered. The completed form serves as the basis for payment of benefits.

Claim Allowance Option - See Allowance Method.

Claim Explanation - See Benefit Statement.

Claims Service Only (CSO) - An arrangement in which claims are processed and payments released by a contractor rather than by the organization bearing the risk of coverage. Under this arrangement, administrative services are not included with the claim services. A self-insured, self-administered group usually seeks this type of arrangement to take advantage of the claims handling expertise provided by an insurance company, processing service center, or third party administrator. (Compare to ASO)

Clasp - A metal attachment on partial dentures or other removable appliances to hold them in place. They are designed to adapt to the clasping teeth to provide maximum stability. There are many kinds of clasps, but they generally consist of two arms joined by a body that may or may not have an occlusal rest.

COBRA (Consolidated Omnibus Budget Reconciliation Act) - Federal legislation relative to continuation of health benefits for all types of employee plans that are provided by employers having twenty or more employees. The most significant aspect is the requirement that employees and/or their dependents who become ineligible for coverage may purchase continued coverage for an additional 18 months (36 months for dependents in the event of an employee's death). Employers operating under Multiple Employer Trust (MET) such as Plan Services are treated as maintaining separate plans, and thus each of the employer units having fewer than 20 employees is exempt from COBRA regulations. Benefit Administrators are responsible for coordinating COBRA coverage options for the insured member and/or dependents.

Top of page

Coinsurance - An arrangement that apportions (assigns) expenses between health plan participants and the insurer. The insured member shares in the cost of covered services, generally on a percentage basis. Coinsurance is based on the plan's Allowance Method and other plan provisions.

Complete Denture - A denture that replaces all of the teeth in an arch.

Composite - A white or tooth-colored resin restorative material. (See Composite versus Amalgam restorations)

Composite versus Amalgam restorations (white or tooth-colored versus silver fillings) - restorations, such as fillings, are typically made of either a composite material or of an amalgam of metals. Composites are tooth-colored or white in appearance and typically have a higher fee and allowance than amalgams, which have a metallic silver appearance. On visible (anterior) teeth requiring restorative treatment, most plans provide benefits for composite (white) fillings. But on molar teeth, most plans will limit the allowance to the equivalent of the silver amalgam filling even if composites are performed. Both materials provide restorative quality. An individual and his or her dentist may decide to place the composite material on a molar tooth for a number of reasons, none of which will change the limitation of the silver amalgam allowance limit on plans with an Alternate Benefit Clause.

Compulsory (Non-Contributory) - A type of plan in which the Plan Sponsor pays the full cost of the premium and has agreed to enroll all eligible members.

Considered Charges - Charges for services rendered or supplies furnished by a dentist or specialist that qualify as covered services and may be paid for in whole or in part by the dental plan. May be subject to deductibles, coinsurance, or Allowance Methods as specified by the terms of the contract.

Contributory - A plan in which a portion or all of the premiums are paid by the insured members.

Coordination of Benefits (COB) - When an insured member is covered by two separate dental plans, the expenses incurred are usually considered by both plans. In order to coordinate, the secondary carrier must obtain a copy of the Benefit Statement issued by the primary carrier. The total payment from all plans is limited to the actual costs due the dentist. Not all plans coordinate benefits. Coordination of Benefits is necessary so that an insured member or dental office does not receive more benefits than the actual expenses incurred.

Covered Amount - The maximum allowed dollar amount per eligible procedure upon which deductibles, coinsurance and other plan options are applied.

Top of page

Crown - With prosthetic tooth structure, an artificial cap designed to restore proper conditions to a damaged tooth.

D

Date of Service - Generally, the actual date a service was performed. For claim determination, we define dates of services as follows: For prosthetics, the "impression" date rather than the delivery date. For root canals, the start or opening date rather than the completion date. For orthodontic treatment programs, the banding date.

Debridement - Removal of diseased or devitalized tissues and foreign material.

Decay - Decomposed tooth structure; caries or carious lesions of the teeth.

Deciduous - The first teeth to erupt in childhood. Also called the "baby teeth."

Deductible - A specified amount of eligible expenses that must be incurred and paid by the insured member prior to any benefits being paid. ineligible or non-covered expenses do not count toward satisfaction of a deductible. Deductible may be annual, lifetime, quarterly, or daily and may vary in amount from plan to plan. Your deductible may vary for different procedure categories based on your plan design.

  • Individual Deductibles - Deductibles applied per person. They may be limited by a Family Deductible depending on the plan.

    • Lifetime Deductible - Deducted once during the duration of the policy. It does not reapply each year.
    • Three Month Carryover - Refers to the deductible of this plan. If the insured member satisfies the deductible in the last three months of the current Benefit Period, the deductible will carry over into the next Benefit Period. Because of this, the insured member does not need to satisfy the deductible in the new Benefit Period.
    • Quarterly Deductible - Deducted each quarter, usually only used with Calendar Year plans:
    • - quarter #1 = January, February, March
      - quarter #2 = April, May, June

      - quarter #4 = October, November, December
    • Daily (per-visit) Deductible - Deducted from each billed visit.
  • Family Deductibles - A feature of some plans that limits the cumulative dollar amount of an Individual Deductible or the cumulative number of Individual Deductibles that must be met by a family.
  • Aggregate Amount Family Deductible - Refers to a specific cumulative dollar amount of Individual Deductibles that when satisfied may waive further application of deductibles for the family. There may be variations.

 

Aggregate Number Family Deductible - Refers to a specific number of family members who must each fully satisfy their Individual Deductible for remaining Individual Deductibles to be waived on the family. There may be variations.

This definition applies to the majority of states. This also includes an unmarried child 19 to 24 years of age who is a full-time student at an accredited school or college and who is dependent primarily on the Insured for support or maintenance. This definition may also include a mentally or physically handicapped child who is totally disabled since the day before his or her nineteenth birthday and who is totally dependent on the Insured for support and maintenance.

Dependent Year - A type of Benefit Period arranged by the Plan Sponsor where each insured member's Benefit Period is set by his/her own effective date on the policy. If the insured member covers his/her dependents, they may each have a different Benefit Period renewal date than the insured member depending on when each person became effective.

DHMO (Prepaid, Capitation Plan) - Defined as a Dental Health Maintenance Organization, this is a legal entity consisting of a network of participating dental providers that provide or arrange dental care with fixed fees for a given population. Dental providers receive Capitation payments based on the number of members who have selected them as their primary general dentist. No benefits are payable for dental procedures from a out-of-network dentist. We do not maintain any DHMO networks.

Eligible Member - A group member who meets the eligibility requirements specified in the group contract to qualify for coverage. It may be necessary to fulfill the group's eligibility period before becoming eligible. (See Procedure Eligibility)

Eligibility Period - A period of time a person must be a member of a group before qualifying for group benefits. For example, an organization whose health and dental benefit plan has a 90-day eligibility period would require 90 days of qualified employment/membership before benefits could begin. An Eligibility Period should not be confused with an Elimination Period.

Elimination Period - A time period within the structure of a plan beginning immediately on an insured member's effective date that must be satisfied before benefits on certain procedures become available. Because Elimination Periods are sometimes called Waiting Periods, care should be taken not to confuse the two terms. (See Eligibility Period>)

Employee Contribution - See Member Contribution.

Employee Year - A type of Benefit Period arranged by the Plan Sponsor where each employee/member's Benefit Period is set by his/her own effective date on the policy. If the member covers his or her dependents, they have the same Benefit Period renewal date as the insured member.
