THE IAED STANDARD

December 2019

 

IAED Standards & Expectations Requirements of Maintenance and Rehabilitation of the Dental Arcades

(This standard is a functional working document and is subject to change without notice)

 

A. Incisors (follow anatomical guidelines)

  1. The incisors should not prevent or interfere with the lateral excursion or rostral-caudal movement of the mandible.

  2. The incisors should not displace the mandible from a neutral position.

  3. The incisor length should not prevent functional cheek teeth occlusion.

  4. Incisor table angle should be directed toward or near the TMJ. (see anatomical guidelines)

 

B. Canines (follow anatomical guidelines)

  1. It is expected that the canine will be buffed and rounded.  

 

C.  Wolf Teeth 

  1. Wolf teeth are to be extracted. (during testing with approval of the steward and

certification veterinarian only.)

 

D. Rostral Profiling of #6 cheek teeth, i.e. Bit Seats (follow anatomical guidelines)

  1. Rostral profiling of the #6 cheek teeth must not compromise the integrity of the tooth.  Ideally there should be minimal loss of functional Occlusal surface. 

  2. Finished bit seat should be smooth.  

 

E. Cheek Teeth (follow anatomical guidelines)

  1. Remove sharp points that may abrade soft tissue.  

  2. Establish, restore or maintain optimally functional cheek teeth arcades by relieving malocclusions, while preserving maximum occlusal surface.                   

  3. Functional table angles should be restored and/or maintained.

  4. After equilibration of the cheek teeth arcades the LETS (lateral excursion to strike, measured in millimeters) should be the same or less but greater than 0mm. (see exceptions in anatomical guidelines)

 

F. Removal of Teeth

  1. Removal of teeth and fragments of teeth should be done in accordance with the AG in a humane and professional manner. (During IAED Testing removal of retained fragments, permanent teeth and deciduous teeth should be discussed with the Steward and approved by the Certification Veterinarian prior to their removal.

 

G. Malformations and Pre Existing Conditions of the Teeth & Oral Cavity

Note: When present, these conditions and others, should be noted on dental chart and

treated in accordance with the AG.  (During IAED Testing possible treatment discussed with attending veterinarian.)

a. Malformed teeth

b. Periodontal disease

c. Decay

d. Openings in the occlusal surface, i.e., open pulp chambers etc.  

e. Buccal and or lingual lesions

f. Damaged bars, damaged tongue

g. Fractured teeth

h. Bone spurs

 

ANATOMICAL GUIDELINES

 

 

The purpose of this supporting document is to define parameters within which equine dentistry

can be performed. While the practical exam will test to a basic standard of care it must be

remembered that dentistry combines both the arts and sciences. To be performed at a high level,

the practitioner must have a solid understanding of the hypsodont anatomy, physiology,

biomechanics, and pathology combined with a knowledge of instrumentation and practical skills.

 

The goal of equilibration is to distribute the pressure and wear of mastication onto as many viable

teeth as possible in order to maximize the longevity and integrity of the equine dentition. The

reduction of ONLY the protuberant teeth allows the opposing excessively worn tooth room to

erupt, so that over time the amount of reserve crown is as symmetrical as possible for respective

teeth. This will ensure an approximately even rate of wear on the respective teeth thus extending

the viability and longevity of the dentition. During the process of equilibration, it is assumed that

the sharp buccal and lingual points will be removed WITHOUT a functional loss of occlusal

surface.

 

During the practical exam, the candidate must demonstrate that he/she understands all the

anatomical landmarks and variations that must be considered for each animal. This will be

documented through charting of the horse following a thorough oral exam. Abnormal pathology

must be completely documented. The horse should be given regular breaks with complete closing

of the speculum at about 5 minute intervals. The mouth should remain closed for at least 10-15

seconds and be rinsed during breaks.

 

Incisors:

• The incisors should be carefully evaluated prior to placement of the speculum.

• When dental work is completed, the incisors should not be placing lateral pressure on the

   mandible

• The incisors should be in contact on as many viable teeth as possible. It is understood that

   incisors that have been excessively worn may be left out of occlusion following the

   reduction of the protuberant opposing incisor. However, in cases where the incisors are

   well aligned, the pressure should be distributed onto as many teeth as possible

• Candidate must use the color of the secondary dentin to determine how much to reduce

   protuberant teeth

• For the purpose of the exam, the secondary dentin should maintain some brown coloration and

  not be taken so far that white dentin is visible.

• Exposure of any pink material reflecting live pulp will result in automatic failure

• The incisors should feel free of mechanical restrictions during lateral excursion

• Incisor table angles should not be so steep that rostral movement of the mandible is restricted.

  The incisor table angles should be close to aligning with the TMJ.

• Large reductions of ALL the incisors should NOT be performed.  If a diagonal bite is present,

  it is expected that candidate will realign bite as much as possible WITHOUT reducing the

  protuberant teeth so much that the secondary dentin remaining is white. Light brown

  secondary dentin should be used as the gauge for when to stop reduction.

• Complete flattening of the incisor table angle is not acceptable

• During equilibration of incisors, adequate technique must be used to prevent excessive heat

  generation.

• Any abnormal pathology such as EOTRH, necrotic pulp horns, fractures, periodontal disease,

  etc. must be thoroughly documented on chart – if present, these must also be brought to

  the attention of the attending veterinarian.

 

Canines:

• The canines should be smooth and rounded but not overly reduced

• Pulp exposure will result in automatic failure

• Any tartar present should be removed

• Presence of gingivitis should be charted accordingly

• Blind canines should be well documented on chart

• Any abnormal pathology such as EOTRH, necrotic pulp horns, fractures, periodontal disease,

  etc. must be thoroughly documented on chart – if present, these must also be brought to

  the attention of the attending veterinarian.

 

Wolf Teeth:

Wolf teeth are to be extracted. (during testing with approval of the steward and certification

veterinarian only.)

 

Cheek Teeth:

• The occlusal surface should have as much width as possible without being sharp

• The buccal and palatal/lingual margins should not be beveled at a 45 degree angle resulting in a

  significant loss of mastication surface

• The tooth opposing a protuberant tooth should always have a natural (i.e. rough) occlusal

  surface. Only the protuberant tooth may be reduced, and not the compromised opposing tooth.

• Rostral profiling of the #6 teeth should only smooth the rostral aspect of the teeth while

  removing minimal occlusal surface. The rostral margins should be uniform and smooth.

• Proper technique must be used so that no iatrogenic soft tissue damage occurs within the oral

  cavity

• Proper technique and instruments must be used to minimize heat production from hand pieces.

  This means using a precise approach to reducing protuberances and only working on the

  smallest surface area possible to obtain desired reduction. Instruments must be sharp and

  in good/safe working conditions.

• When reducing large protuberances, the candidate should continually assess the color of the

  secondary dentin of all pulp horns and make sure that some brown coloration is

 maintained throughout procedure. No teeth should be reduced so much that only white

  secondary dentin is seen. Any pink coloration on any pulp horn will result in automatic

  failure.

• Any abnormal pathology such as necrotic open pulp horns, fractures, periodontal disease,

  infundibular caries, peripheral cemental caries, masses, etc. must be thoroughly

  documented on chart – if present, these must also be brought to the attention of the

  attending veterinarian.

• The occlusal surfaces should be balanced to the extent possible, but they should not be smooth!

  Only protuberant areas should be reduced!

• Exam horses will be screened to ensure that they have fairly uniform table angles (no shear

  mouths), therefore candidates should only do minimal adjustments of table angles – if

  any. There may be cases where a few teeth require an angle adjustment, but as a whole,

  the table angles should be respected and maintained at all times. They should remain

  uniform and consistent.

• During equilibration, candidate must not eliminate the Curvature of Spee.

• When the speculum is removed and the cheek teeth come together, the paired quadrants

  (100/400 and 200/300) should have simultaneous occlusion of as many viable cheek teeth

  as possible.

• Primary tooth strike is a single tooth or area of tooth causing separation of arcades for more

  than half of the “in occlusion excursion”.

• Secondary tooth strike is a single tooth or area of tooth causing separation of arcades for less

  than half of the “in occlusion excursion”.

• “In occlusion excursion” for the purpose of testing is measured from the first point of contact

  during excursion through to the point at which the most lateral point of the upper arcade

  is vertical to the lateral edge of the opposing arcade.

• Lateral excursion should be free and unrestricted.

• Compromised teeth that were excessively worn from protuberances may remain out of

  occlusion during lateral excursion.

• Transitions of malocclusions should be blended to allow for rostral/caudal movement of the

  mandible during mastication.

• Incisor reductions resulting in 0mm LETS (i.e. 100% occlusion) of cheek teeth should NOT be

  performed. Only mild angle changes or realignments of the incisors are necessary if

  candidate ONLY reduces the PROTUBERANT cheek teeth.

• The cheek teeth should have enough occlusion that some separation of the incisors occurs

  during lateral excursion – the only exception would be cases where very poor cheek teeth

  occlusion is present prior to equilibration. If this happens, the candidate must carefully

  document the poor occlusion PRIOR to equilibration and use that as a limiting step for

  how much work can be performed on the cheek teeth.
