Lower Suction Dentures SEMCD

Dr. Abe Suction Effective Mandibular Complete Denture (SEMCD)

One of the most difficult results to achieve in clinical dentistry is suction and stability on the full lower denture. The concept developed by Dr Abe eliminates the problem of the lower denture lifting, and this is done by creating an effective seal around the entire border of the denture base.

This concept, developed by Dr Jiro Abe in Japan, enhances the suction effect of full lower dentures and allows for denture suction even in patients with advanced resorption of the mandibular alveolar ridge. This newly developed technique for achieving effective suction and stability of the full lower denture has become an indispensable part of treating patients.

This suction mechanism has been spreading worldwide, and the popularity of this system shows no signs of slowing.

How is this done?

• Revolutionary new impression technique using slow setting, high definition material to capture muscles of cheek and tongue
• New tooth positioning to work in harmony with your muscle
• High definition impression materials
• Special bio-functional teeth
• Lower distortion acrylic injection machine to gain superior fit
• Adjustable articulator to simulate your jaw movements
• Special contouring and shaping of the denture to work in harmony with your muscle movements when chewing and speaking while in function

Will it work for me?

• 80% of patients are candidates for our lower suction dentures.
• An exam will be performed in a consultation to see if you’re a candidate, but the level of suction will be known after the final impression is taken. Even if you’re not a candidate for lower suction dentures you will have a better fit. Food will not be as likely to get underneath your denture. 
• These dentures are incredibly more biocompatible than conventional dentures. We still offer conventional dentures for those that need an affordable option.

The simple 4 step “Suction Effective Mandibular Denture” technique presents a dramatic new approach to complete denture prosthetics, providing a new experience for all denture wearers.

You should remove an implant-supported denture daily to thoroughly clean the denture and gum area. Just as with regular dentures, you should not sleep with the implant-supported dentures. Some people prefer to have fixed (permanent) crowns and bridgework. Your dentist will consider your particular needs and preferences when suggesting fixed or removable options.

How Does It Work?

There are two types of implant-supported dentures: bar-retained and attachment-retained. In both cases, the denture will be fabricated with an acrylic base that looks like gums. Composite or acrylic teeth that look like natural teeth are attached to the base. Both types of dentures need at least two to three implants for adequate support.

Bar-retained dentures — A thin metal bar that follows the curve of the jaw is attached to three to five implants that have been placed in the jawbone. Snap on or other types of attachments are fitted to the bar, the denture or both. The denture fits over the bar and is securely clipped into place with the attachments.

Attachment-retained dentures — (stud-attachment dentures) — Each implant in the jawbone holds a metal attachment that fits into another attachment on the denture. In most cases, the attachments on the implants are round-shaped ("male" attachments) that fit into sockets ("female" attachments) on the denture. In some cases, the denture holds the male attachments and the implants hold the female ones.

The Implant Process

The implants are usually placed in the jawbone at the front of your mouth because there tends to be more bone in the front of the jaw than in the back. This is generally the case, even if teeth have been missing for some time. Once you lose teeth, you begin to lose bone in that area. Also, the front jaw has fewer nerves or other structures that could interfere with the placement of implants.

The time frame to complete the implant depends on numerous factors. The shortest practical time frame is approximately five months for the lower jaw and seven months for the upper jaw. This includes surgeries and placement of dentures. However, the process can occasionally require a year or more, especially if you need bone grafting or other preliminary procedures.

Two surgeries are usually needed. The first one places the implants in the jawbone under your gums. The second surgery exposes tops of the implants. The second procedure takes place three to six months after the first.

A one-stage procedure is used in some cases. With this procedure, your dentist can place the implants and the supporting bar in one step. This procedure has a high success rate.

Initial consultation

Before any work is done, you will visit either a dental specialist or general dentist who has advanced training in the placement and restoration of implants.

During the exam, the dentist will review your medical and dental histories, take X-rays and create impressions of your teeth and gums so that models can be constructed. In some cases, the dentist may order a computed tomography (CT) scan of your mouth.

This shows the locations of your sinuses (located above your upper teeth) and nerves. It allows the dentist to make certain that sinuses and nerves will not be affected by the implant placement. A CT scan also may be done to see how much bone is available and to determine the best locations for implants.

If you are not already wearing a complete denture to replace your missing teeth, your denturist will create one for you. You will use this temporary denture until the implant-supported denture is placed.

It will require about four visits spanning several weeks to complete this denture. By making this temporary denture, your denturist is able to determine the best position for teeth in the final denture. The temporary denture also can be used as a backup if something happens to the final implant-supported denture.

Once the temporary denture is finished, the dental specialist will use a copy of it as a guide to help place the implants in proper positions. Holes will be drilled in the denture copy so that the dental specialist can see where the implants will be placed.

Possible Complications

In addition to the risks of surgery and implants failing, a bar-retained denture carries certain risks of its own.

A bar-retained denture needs space on the denture framework for the special attachments that are fitted to the bar. This results in less space available on the denture framework for the teeth to be fitted. Because of this, teeth can sometimes come loose from the base. But this is a problem that is easily corrected.

Also, when the bar is attached to the implants, it is important for the bar to be evenly balanced on each implant. Dentists refer to this as a "passive fit." If the fit is not passive, the extra strain on the bar can cause screws to loosen. If you grind or clench your teeth, it is more likely that parts of the denture will break or that your implants will become loose.

What Should You Expect from Your Implant Retained Denture?

Your implant-supported denture will be more stable than a conventional denture. You will find it easier to speak and you won't have to worry about the denture becoming loose or falling out of your mouth. You will probably be able to eat foods that you could not eat before. However, you should not chew hard or sticky foods because they can damage the denture.

If you have an implant-supported denture in your upper jaw, it can be made to cover less of your palate (roof of your mouth) than a regular denture. This is because the implants are holding it in place rather than the suction created between the full denture and palate.
