Dentures:

  • Full prosthesis:

The denture is a removable device that is used to replace missing teeth in the mouth.

After the loss of all teeth, the gum closes and heals over time.

The installation of a complete denture will allow you again to chew, smile and speak well.

These prosthesis are  supported on the gums, by soft and hard tissues of the oral cavity.

The upper denture covers the whole Palate (roof of the mouth) which provides suction for stability.

The lower prosthesis looks like a horseshoe and she holds in the mouth only by gravity. The complete lower prosthesis is a prosthesis that will often move because there is no suction; the movements of the tongue, of the lower lip and mouth muscles will often dislodge the prosthesis.

Complete dentures are removable, which makes them easy to remove for cleaning, as well as to sleep at night. Dentures should be changed every 5 to 8 years, because there is a wear of teeth of the prosthesis. The shape of the gum also changes each year. This affects mastication and the functioning of the prostheses.

The bone and gums of the mouth resorb over time, this causes a collapse of the face and the problems at the level of the temporomandibular joint. It is important to visit your denturist in order to examine your dentures and also to  replace them every 5 to 8 years.

The bone and gum resorb under the force exerted by the denture and no longer offer the same support surface that the prosthesis needs.This causes irritation, discomfort at the level of  chewing, sagging of the upper lip and many other problems.

The manufacturing of a new denture extends over 5 to 6 appointment:

R-V 1: Primary impression with dental trays pre-manufactured.

R-V 2: Final impressions with individual dental trays are performed.

R-V 3: Adjustment of the height and articulation. The denturist adjusts a cylinder of wax to the approximate height of the final prosthesis, it will then trace the Center, the smile line, plan, parallelism, lip support, and bite. Finally, the denturist will choose the color and the shape of the teeth with the PATIENT.

R-V 4: This meeting is to try the dentures with teeth in wax (this is not the final prosthesis), the denturist ensures that the bite is correct to 100% and the teeth close together. Then the patient confirms if the appearance and color of the denture teeth match his taste. When everything is approved by the patient, the denturist proceeds to the final manufacturing of the prosthesis.

R-V 5: This appointment is well expected by the patient because he or she will receive the new dentures. The denturist puts prostheses in the mouth and makes the necessary adjustments. He also explains to the patient the regular maintanence.

R-V 6: Appointment of control. The denturist ensures prostheses are doing well and that the patient is able to chew well and live with the new teeth. Later if the patient needs adjustment, they can meet the denturist for further adjustments.

Note: it is important to consult your denturist annually to check if everything’s under control.

  • Partial denture:

The partial prosthesis is a prosthesis used to replace one or more missing teeth in the mouth. The partial fits in the mouth with hooks hung on the remaining natural teeth in the mouth. So she relies on the gums too.

Partial dentures are relatively stable in the mouth because they hold mechanically and not by gravity or suction. There are hooks or metal or nylon (from the color of the gums) which grab to the natural teeth, this eliminates the movements of the prosthesis caused by chewing and by the tongue.

The hooks may be invisible but sometimes they may also be apparent, all depending on the type of partial prosthesis chosen by the patient. At the Msmiline clinic, we manufacture 4 kinds of partial dentures: partial dentures with a metal, acrylic, nylon (flexible acrylic) and metal-nylon structure.

1) Partial metal prosthesis: The partial metal prosthesis is the solution that will offer the most stability, as well as the best aesthetic. It is made with a metal skeleton with hooks that grip on the natural teeth which holds it in the mouth. The partial metal prosthesis is very stable and offers a minimum of mobility while being very comfortable and slim. This prosthesis offers less infiltration of food. In addition the metal is thin and conducts heat so it gives a more natural and comfortable effect. It allows you to taste your food better. The metal hooks are adjustable and the hooks can be tightened for better stability. There are 2 kinds of metal that can be used, chrome, which is the most standard as well as titanium. The difference is that titanium is biocompatible so there can be no allergic reaction and it is 50% lighter than chromium. It is a very stable prosthesis that will allow you to eat and smile with confidence.

2) Partial Nylon Prosthesis: Often called Flexite or Valplast, the nylon prosthesis is a partial denture that is almost invisible. The nylon with which the prosthesis is manufactured is of the same color as the gingiva. The hooks are also made of the same color. This prosthesis is a very stable solution and offers the least infiltration of food. Nylon is thicker than metal. The prosthesis is flexible at the level of the hooks so it allows a very good stability. Unfortunately it is not a conductor of heat. The hooks are not adjustable offering less retention. When adding teeth, the process is more difficult and takes longer. This prosthesis is biocompatible.

It is a very stable prosthesis that allows you to eat and smile with confidence. This solution allows us to manufacture unilateral prostheses, so a prosthesis for one side of the mouth when there is only one or two teeth missing.

3) Partial Acrylic Prosthesis: Acrylic Partial Prosthesis is the most economical prosthesis. It is a prosthesis made of hard acrylic. There are metal shaped hooks that fit on the teeth. It is often a prosthesis that is used for temporary solutions. There is a lot of food infiltration and it is thicker and more fragile than other types of prostheses. Often it covers the majority of the tissues of the mouth. There is often mobility and requires several adjustments. Adaptation is also more difficult. Often the hooks are visible.

4) Metal-nylon prosthesis: This is the combination of the stability and comfort of the metal and the aesthetics of the hooks nylons of the color of the gum.

5.Prosthesis on implants:

A dental implant is an artificial root that resembles a screw. This makes it possible to support the new dentition by being placed in the bone of the mouth. The implant is made of titanium which is a biocompatible material, it means that it will integrate with the bone.

The placement of the implant requires a small surgical procedure that is usually done with local anesthesia and lasts between 45 minutes and 1 hour.

In addition, dental implants allow the resumption of osseous stimulation to stop bone resorption. When there is a loss of teeth, the bone is not stimulated. It is therefore the implant that will stimulate the bone.

The implants allow to have a mechanical stability which will make chewing easier.

The conventional prostheses hold in the mouth with suction and gravity. However, the movements of the mouth and the facial expressions can cause a mobility of prosthesis.

The implants will then allow to have a much improved stability of the prostheses . To regain stability of your lower prosthesis, dental implants are the only solution.

There are different solutions for prostheses on implants. The number of implants varies between each solution.

Once the implant is integrated into the bone, we can then attach the prosthesis with the implants.

Choice of treatments for prostheses on implants:

  • 2 implants in the lower jaw: spherical fasteners or Locator. Stability 5/10
  • 3 implants in the lower jaw: spherical attachments or Locator. Stability 7/10
  • 4 implants in the lower jaw: with spherical or locator attachments. Stability 8/10
  • 4 implants in the lower jaw: with bar (there are several types of bar, to choose according to your needs and your expectations). Stability 10/10
  • 5 implants in the upper gingiva: with bar and open palate. Stability 10/10 According to your needs we will guide you and help you choose the treatment plan you need.

Additional services:

  • Filling of dental prostheses
  • Soft base
  • Filling of dental prostheses:

Over the years, the shape of the gingiva changes and there is bone resorption, this causes an instability in the prostheses. The relining consists in filling the space created between the prosthesis and the gingiva. relining is done with a new layer of acrylic that will bond with the existing acrylic of the prosthesis.

There are 2 ways to make the reline:

  • In the chair:

The patient presents himself with his prosthesis and the relining is done on the spot. This lasts about 1 hour. The patient leaves with his prostheses.

  • At the laboratory:

This involves taking an impression with the prosthesis and performing the reline in the laboratory. This can last 24 hours, which means that the prostheses must remain with the denturologist.

  • Soft base:

A soft base is a material that resembles a soft rubber of the same color as your prosthesis. The lower prosthesis is often unstable and causes ulcers, pressure and pain. The soft base absorbs masticatory pressures on your gums and makes the wearing of the prosthesis more pleasant.

Your denturologist recommends you have a soft base when your lower gum is too resorbed. It is recommended to change the soft base of your prosthesis every 2 to 3 years because this is a material with micro porosities, which often has infiltrations Of microorganisms. Maintenance of the soft base is essential
