Study Notes

Types of Dentures and Their Purposes

Interim dentures are designed to manage inflamed tissues and provide temporary restoration.
Transitional dentures serve to fill the gap between natural teeth removal and final prosthesis placement.
Immediate dentures are created prior to surgery for immediate use after tooth extraction.

Characteristics and Concerns

Interim and partial dentures share the common characteristic of being removable and temporary.
Main concerns for patients opting for interim or immediate dentures include adjustment to new oral structures and aesthetics.

Extraction Processes

Staging extractions allows for a gradual removal of teeth, minimizing trauma to tissues.
Taking study models and articulating them is crucial for analyzing occlusion and designing accurate prosthetics.

Denture Insertions and Surgical Tools

Denture insertions typically occur in a clinical setting, ensuring a controlled environment.
A surgical guide directs the placement and alignment of implants or dentures during procedures.

Occlusion and Extraction Stages

Premolars play a significant role in occlusal balance and functional efficiency.
During stage one extraction, not all preparatory steps may be performed, leading to procedural gaps.

Tuberosity and RMP Issues

Failure to maintain contact between the tuberosity and retro molar pad may disrupt proper denture fit.
Adjustments like relining or remaking prosthetics can address missed contacts during stage one extraction.

Denture Fabrication Techniques

Split trying aids in evaluating fit and aesthetics during denture fabrication.
Recommended height for setting lower denture rims is essential for achieving proper occlusion.

Bite Position and Tooth Design

The case is restored in the patient’s reproducible bite position to ensure functional alignment.
Incorporating additional cusps and curvature in posterior teeth enhances occlusal stability and function.

Surgical Guides in Dentistry

The surgical guide assists in ensuring precision during implantation and denture placement.
Benefits of a clear acrylic surgical guide include improved visibility and accuracy during surgical procedures.

Bone Contouring and Alveolar Plasty

A bone contouring template helps shape the alveolar process for optimal denture adaptation.
Alveolar plasty reshapes the bone structure to support prosthetic devices effectively.

Denture Workflow and Adjustments

Tabs in denture design allow for adjustments in length, width, and depth as needed.
The depth adjustment in workflow ensures proper fit and function of the final denture.

Initial Steps and Workflow Options

The first step in immediate and interim denture workflows involves comprehensive planning and modeling.
Clinical remotes should be discussed early to assess patient needs and expectations for dentures.

Final Impression Considerations

Leaving one stop for vertical final impressions is crucial for maintaining occlusal relationships during denture setting.
