Intro to dental lab tech

pt.1

Maxillary

Upper mouth

Mandibular

Lower mouth

Anterior

12 front teeth (6-11, 22-27)

Postierior

20 back teeth (1-5, 12-16, 17-21, 28-32)

Central line

The middle line

Anterior teeth names

• Centrals

• Laterals

• Canines

Posterior teeth names

• Bicuspids/ Pre molars

• Molars

Labial Surface

Outward facing, the surface that touches the lips

• Anterior tooth surface

Lingual

Inward facing, the surface that touches the tongue

• Anterior tooth surface

Mesial

The surface that’s closest to the mid-line

• Anterior tooth surface

Distal

The surface farthest away from the mid-line

• Anterior tooth surface

Incisal

The teeth that come together when biting, the cutting edge.

• Anterior tooth surface

Buccal

The surface that touches the inside of the cheek

• Posterior tooth surface

Occlusal

The surface of the tooth that breaks down food, touches its opposing tooth when jaw is closed

Fixed Restoration

Restoration that is permanently placed in patient’s mouth with no removal

Removable Restoration

Restoration that has the ability to be taken in and out of patient’s mouth

2 Branches of Process

• Analog (Traditional lab labor)

• Digital (Uses CAD or CAM)

• Both require the same data

  • 1. Maxillary representation

  • 2. Mandibular representation

  • 3. Jaw relations

Analog Impression

• A negative reproduction of the mouth, taken with elastic material

• Required

  • Full arch impression

  • Quadrant impression

  • Triple tray

Digital Scan

• Taken with digital scanner

  • Direct Scan: Using a wand

  • Indirect Scan: Converts a shape into digital representation

    • STL: Digital format used to pass digital data

Bite Records/Registration

A representation of how the patients upper and lower jaws relate

Master Model

The primary model where restoration is shown

Opposing Model

A model representing the opposing dental arch to accurately assess occlusion and restoration fit.

Articulator

A hinged device that simulates opening and closing movement
