    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.
