Dental Lab Prescriptions and Surgical Guides

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.
