7 Tips to Make the Most of Each Records Appointment
Making the most of records appointments can help to ensure that patients receive the best dental treatment and restoration. Rushing through records appointments or model creation can have devastating life-long consequences for patients. It is important to give these tasks the time and attention that they deserve. After all, patients carry evidence of your attention to detail ever after, speaking louder than their words as a testament to your skill and patience in the craft.
1. Start with Top Quality Impressions
Impressions should be given the upmost attention, as these will later be used for diagnosis and treatment planning. Doing a good job with dental impressions can save time and money down the road for everyone involved. Good dental impressions can also be used later for wax-ups and the fabrication of restorations.
2. Choose the Appropriate Material
It is vital to select the right material to effectively capture the impression of the mouth. Flextime Putty is a material that allows multiple pours and captures all impressions well. Before placing the impression, the teeth should be dried well. When taking the impression, all tooth surfaces should be captured, along with the hard palate.
3. Make Sure Casts are High Quality
Casts should be made following the instructions on the stone that is used carefully. Errors in the powder to water ratio can affect the accuracy of the cast. If possible, it may be helpful to use a vacuum mixing machine to keep the mix free of air bubbles.
4. Use the Right Instruments
A good articulator can make all the difference when taking records. Articulators should be able to accept a facebow transfer and be altered when needed. Offices and professionals may differ in opinion of the best articulation system.
5. Perform Facebow Transfer Properly
Facebow transfers are done in order to mount the maxillary cast on the instrument at the same place that the maxilla falls on the skull of the patient when the patient is standing. The relationship of the maxilla and the mandible should also be replicated. The proper facebow will help make the transfer easier.
6. Find and Document Centric Relation
Finding centric relation is a matter of learning to properly position the patient and apply the right amount of pressure to correct occlusions. Bimanual manipulation has shown to be a good way to find centric relation. However, several other methods exist that may be preferable depending on the dentist’s training.
7. Use the Right Techniques for Mounting the Models
Mounting the models onto the articulators is much easier when the facebow system allows the mounting jig to be separated from the earbow. After the maxillary cast has been stabilized and mounted, the mandibular cast can be mounted using the centric relation record. Using items such as nails or glue may help to keep the models in the precise placement, after which stone can be placed between the casts and the mounting plates.
