Custom Tray Fabrication

T or F. Blue for tray extension while Red for denture base extension.

True

Reduction or elimination of undesirable pressure.

Base-Plate Wax

Shaping of border areas of an impression tray by functional or manual manipulation of the tissue adjacent to the borders to duplicate the contour and size of the vestibule.

Border Molding

Six Functional Movements

Smiling, Whistling, and Pickering Motion, Sucking Motion, Licking the Lips and Other Tongue Movement, Swallowing Motion, Occluding, Opening and Closing and Side to Side Movements of the Jaw

T or F. Open Mouth Technique is the most common while Close Mouth Technique requires occlusion rim or teeth.

A technique used to record highly mobile or hypertrophic tissue with minimum displacement.

Window Tray Impression Technique

Most often seen anteriorly and may be particularly prominent in patients with combination syndrome.

Mobile Tissues

The seal area at the posterior border of a maxillary removable dental prosthesis; acts as a barrier and prevents food accumulation beneath the denture; retention as primary function.

Post-Palatal Seal

An imaginary line located at the junction of the attached tissues of the hard palate and the moveable tissue of the immediately adjacent soft palate.

Anterior Vibrating Line

Posterior Vibrating Line

Two Techniques of Recording the Posterior Palatal Seal

Arbitrary Technique, Physiologic Technique

Two Arbitrary Techniques

Scrape the cast with the following measurement: Median Raphe Region

0.5-1.0mm Deep

T or F. Cuspid's Bow due to the projection of the anterior nasal spine.

False

Both the nostrils are held firmly while the patient blows gently through the nose.

Valsava Maneuver

Recorded during jaw relation; groove is scraped slightly anterior to this line V-shape 1-1.5mm deep and 1.5mm wide.

Boucher's Technique

Recorded after making final impression head is flexed downward by 30°; Korrecta wax no. 4, Iowa wax, Adaptol.

Fluid Wax Technique

Recorded during border molding of the special tray before final impression is made.

Stick Compound Technique

Denture border is extended 8.2mm beyond the anterior vibrating line; head is flexed downward 30°.

Extended Palatal Technique

Four Types of Troubleshooting

Overextended, Under extended, Under postdammed, Over postdammed

Occurs when distal border of the denture extends onto the active portion of the soft palate; patient complains that swallowing is difficult or painful; marked with indelible pencil.

Overextended

Common cause of failure of the posterior palatal seal; results in the loss of retention; failure to identify posterior vibrating line.

Under extended

Failure to effectively place the tissues of the posterior palatal seal area results in poor seal and reduced retention.

Under postdammed

Over scraping of the cast can result in over postdamming; moderate and severe postdammed.

Over postdammed

Postdamming can result in pressure symptoms on the tissues; an area of redness or tissue irritation may be seen

Moderate

Postdamming causes downward displacement of the denture.

Severe
