Dr. Jiro Abe is giving his lecture about Mandibular Suction-Effective Complete Denture (SEMCD) combined with BPS Biofunctional Prosthetic System (BPS) by Ivoclar Vivadent Inc.


◆Part 1
Dr. Abe explains “The Suction Mechanism of Mandibular Complete Denture” covering key points of both Maxillary and Mandibular Complete Denture seals and closures.


◆Part 2
Dr. Abe explains about “Overcoming difficulties in achieving mandibular denture suction through intraoral examination” Dr explains about why he selected BPS from among many other approaches, and he explains SEMCD intraoral examination sheets, and how to determine suction success rate forecast during examination, and lastly he covers advanced techniques for overcoming difficulties in achieving mandibular suction.

By watching this lecture, you will learn the key concepts of Dr. Abe's SEMCD suction dentures and how to practically use them in your practice starting tomorrow.

◆Part 1.3: Mandibular Complete Denture
・The Seal of the Labial and Buccal region
・The Seal at the sublingual fold 
・The Seal at the retromylohyoid fossa:
-How to perform Compensatory Closure at the retromylohyoid fossa
・The Posterior end seal around retromolar pad
-Close Contact closure with the interior side of the denture and the retromolar pad tissue
-Exterior closure over the denture base by close contact
with the tongue side wall and the buccal mucosa on the Retromolar pad.

・Definition of SEMCD and Suction effectiveness


39:19〜
◆Part 2 Overcoming difficulties in achieving mandibular denture suction through intraoral examination
◆Part 2.1 Why did I select BPS from among many ways?
In this module, Dr. Jiro Abe explains:
Question: What is the most important factor in obtaining patient satisfaction? Accurate reproduction of jaw relationship? To obtain Lower denture stability and retention?
BPS in 4 steps:
Step 1: Preliminary impression Centric tray
Step 2: Precision Impression Gnathometer M (UTF)
Step 3: Tooth set-up Wax denture Try-in
Step 4: IvoBase system Ivocap Polymerization


54:14〜
◆Part 2 Overcoming difficulties in achieving mandibular denture suction through intraoral examination
◆Part 2.2 Intraoral Examination for SEMCDs
In this module, Dr. Jiro Abe explains:
Anatomical Risk Factors:
・Severe alveolar bone resorption
・Poor quality of sublingual spongy tissue
・Inadequate space in the retromylohyoid fossa
・Poor shape of the retromolar pad
・Strong tongue retraction during mouth opening
Intermaxillary Risk Factors:
・Jaw relationship (Type 1, 2, 3)
・Large discrepancy between the habitual jaw position and the true one
・TMJ Dysfunction
Intraoral examination for SEMCDs details, how to determine suction success rate forecast during examination
1.Extent of alveolar ridge resorption
2.Sublingual Spongy Tissue
3.Space in the retromylohyoid fossa
4.Shape of the Retromolar Pad


1:07:56〜
