Steps to Occlusal Appliance Success
Step 1: Acquiring the best impression possible.
Ensure that the tray is fit properly. It is important to fully capture all of the teeth. Very often the distal abutment has distortions or is incomplete. Being sure the tray is large enough is also very important. The tray should not impinge on areas such as the maxillary tuberosities, the retromolar pads, or the facial or lingual folds. When the tray is seated, the pressure should not be excessive, and the tray should be held in place without further compression while the impression material is setting. A custom tray is the most predictable tray choice.
It is recommended to use polyvinyl or polyether material, this will allow multiple pouring of the impression and facilitate the checking of fit after processing.
It is very important that the appropriate tray adhesive is used, and that the entire surface of the inside and borders of the tray be coated. If the impression separates from the tray in any way the distortion may cause an ill-fitting appliance. The same procedures must be followed for the impression of the opposing as well.
Ensure that adequate impression material is used, especially the posterior of the tray.
Drying the teeth before seating the impression will allow better adaptation of impression materials to the tooth surfaces.
Step 2: Construction Bite
The use of a construction bite is one of the most important steps that the clinician can take to ensure the desired occlusal relationship. If no bite is taken or just a MIP bite is taken, then the occlusal relationship will change significantly if the technician is left to open the bite on a simple hinge articulator.
If the clinician makes a construction bite in the patient’s mouth to the desired specification then when the models are articulated they are in the correct position. You have effectively used the best articulator to create the relationship, that being the patient’s own jaw relationship. Regardless of your occlusal philosophy, this puts you in the driver's seat. If you take a bite in CR or an opening from MIP, you control the results.
Types of Construction Bites
- Horseshoe shape
- 1CM thick
- Incisal edges of incisors should not be covered; it should be lingual of the lower incisors
- Shorten the distal ends so that the last molar is not covered
Establish the VDO and occlusal relationship desired, then use a PVS bite registration material to lock in the posterior for articulation purposes.
Step 3: Take A Face-Bow
Specifically, I like the Kois facial analyzer bow. This tool allows you to take a very quick face-bow record, and establish the relationship of the central incisors to the condyles and capture an accurate horizontal and plane of occlusion.
It also allows the technicians to mount your casts quickly and accurately onto a semi-adjustable articulator (Panadent). Mounting the case onto a semi-adjustable articulator will enable the technician to more accurately refine the appliance to your occlusal records.
Prescribing a Talon™ Appliance is your silver bullet to patient comfort.
Talon™ appliances are much easier to deliver than conventional hard appliances.
Most clinicians have often experienced that splints and orthotics can take an inordinate amount of chair-time to get the patient comfortable. Talon™ appliances solve this challenge by combining the best features of a hard splint and a soft splint while eliminating the inherent disadvantages of either type.
The portion of the appliance that comes in contact with the teeth is made of a soft, thermoplastic polymer. The appliance can be pre-warmed in warm water to allow for a “custom fit” every time the patient inserts it. It is this attribute that allows Talon™ appliances to deliver an extremely comfortable wearing experience while maintaining maximum retention.
Talon™ material is engineered for ideal comfort and retention at body temperature. It provides superior retention without creating any forces that can cause the teeth or tissues to become sore. Internal adjustments are virtually nonexistent due to the “custom fit” experience at each insertion. The pliable thermoplastic interior is bonded to a hard acrylic shell that allows for occlusal build up and normal occlusal adjustments. Unlike other thermoplastics currently available, Talon™ maintains its original flexibility for years. A hard acrylic is chemically bonded to processed Talon™ material to form splint's occlusal surface, allowing easy, precise occlusal adjustments. Proper proprioceptive response with the opposing dentition is maintained.
Benefits of Talon™ Appliances
Ultimate comfort while still maintaining maximum retention.
Allows for Adjusting and Polishing
Accurate and adjustable hard occlusal surface allows for normal occlusal adjusting and polishing.
Great Treatment Options
Great treatment option for patients needing a splint for bruxism, periodontal splinting, orthodontic stabilization, or TMJ dysfunction.
