Study Notes
Denture Fabrication
- Adjusting the occlusion rim contour during denture fabrication allows for a more accurate representation of the patient's natural bite.
Occlusal Records
- Inter-occlusal records are important for capturing the patient's centric relation.
- A second attendance may be necessary to refine the occlusal records.
Determining Midline
- The recommended basis for determining the midline of a denture is by using the facial midline.
- The facial midline is not a reliable intraoral landmark for determining the midline of a denture.
Measuring Canine Distance
- The actual canine to canine distance on a cast can be measured using a caliper or ruler.
- The width of the six anterior teeth is often compared to the width of the nose.
Posterior Tooth Selection
- The condition of the ridge is an important factor to consider when selecting a fully anatomical posterior tooth for a denture.
- A limiting factor for selecting a fully anatomical posterior tooth is the patient's oral anatomy.
Denture Retention and Comfort
- Well-fitting record bases and occlusion rims play an important role in the retention and comfort of a denture.
Digital Fabrication
- The advantage of having digitally fabricated dentures is improved accuracy and efficiency.
- Patients often provide old photos of themselves to help select teeth for dentures.
Tooth Selection
- The term "re-veneering" refers to using an existing denture as a framework to build a new denture.
- The incisal edge contour is important in dentures as it affects the overall aesthetics.
Recommendations
- The recommended material for dentures is not specified, but depends on individual patient needs.
- The vertical dimension of the teeth should be considered when selecting teeth for dentures.
Canine Positioning
- The length of the centrals and canines can be determined using the smile line.
- When determining the position of the canines, the shape and size of the face, and the width of the six anterior teeth should be considered.
- A wax rim or a can be used to position the canines.
- The distal of the canines should be added to the wax rim or can.
- The smile line falls at the height of contour of the canines.
- There are multiple ways to determine the position of the canines, including using old photographs and facial measurements.
