Dental prosthetics

Dental crowns

A dental crown is a layer of strong material that looks like a natural tooth and covers, restores and protects a tooth. It is permanently fixed by a special adhesive cement. It is necessary when a tooth is extensively decayed, fractured, worn or treated by root canal treatment.

Dental crowns at the D Dental Office are manufactured on site using Cerec technology. They are extremely strong, durable and aesthetic restorations.

Dental bridges

A dental bridge is a fixed prosthesis that replaces one or a few missing teeth. It is made up of artificial teeth, called pontics, fixed between two crowns, called abutments, which run from one end of the toothless region to the other. It is often made of a particularly solid structure, like zircon or metal, covered with a layer of aesthetic porcelain.

Indications for a bridge

We choose to make a bridge when we have missing teeth, but there are special conditions to prefer it over the other options. We will always prefer a dental implant, when possible, to replace missing teeth, for several reasons. But, when an implant is not possible, or, when a particular case makes it difficult, we can choose a dental bridge.

It may be a valid option, especially if the abutment teeth, the teeth that hold the bridge in place, are already damaged or already have large restorations and will benefit from being covered and restored more securely by a bridge. But, it is only possible when there are strong enough teeth on either side of the toothless region. Suspended bridges are no longer manufactured because of the high chances of fractures due to the lack of support of the suspended pontic.

Procedure for bridge fabrication

A bridge can take two to three appointments. After a diagnostic appointment, the complete examination, the first appointment is to anesthetize the abutment teeth and prepare them for the bridge. The dentist removes all old fillings and cavities. If the teeth do not have enough remaining structure to support the bridge predictably in the long term, your dentist may advise you that they will need additional treatment, such as reconstruction for bridge or even root canal treatment.

When the abutment teeth are carefully prepared, they are shaped like the original tooth, but smaller, to make room for the ceramic layer that will go over it. The dentist then takes a digital image of the teeth with the 3Shape scanner, to email it to the laboratory that is contracted to fabricate the permanent bridge.

The dentist will then make the temporary bridge, which is made of plastic. It is easy and quick to manufacture. It will be used for chewing and smiling, until the fabrication of the permanent bridge. The dentist may choose to have the lab finish the permanent bridge at the next appointment, so it would take a total of two appointments. Or, he can ask to fabricate and send the framework for a try-in, to make sure it fits perfectly, before the bridge is completed, for a total of three appointments.Smaller bridges, which have three units, are often made in two appointments. Longer bridges, which have four or more units, often require three or more appointments.

Since a bridge is fixed, it is more comfortable and practical than a partial denture. But, a disadvantage is that it can accumulate food under the pontic and over time more space can form below, as the bone in the toothless region naturally resorbs. which accentuates the problem of food retention. The other disadvantage would be in the event that a part of the bridge fractures, the whole bridge has to be changed. Whereas with an implant, only the fractured unit would need to be changed.

Removable partial and complete dentures

Removable dentures are the least expensive options for replacing missing teeth. These are devices that must be removed after each meal to rinse them and rinse the mouth. They should also be removed at night to avoid fungal infections. Partial dentures replace missing teeth when there are existing natural teeth to hold it in place. Full dentures replace all upper teeth or lower teeth when there are no remaining teeth.

They are relatively easy to make and do not require anesthesia or invasive procedures. However, they can be bulky and difficult to get used to, because of their size and thickness in the mouth. But, when implants and bridges are not possible, they can be a suitable option and most patients get used to them over time.

Removable dentures are tailor-made and their shape and design depend on the number of missing teeth and their positions. We offer two levels of quality.

The low end option is made completely from acrylic, an inexpensive plastic material that is thicker than the high end option. It is more economical and faster to manufacture, but it is thicker, less stable and therefore less comfortable. It only takes two to three appointments to make it.

The high-end option features a metal frame in chrome-cobalt, a material that gives it much more strength and less thickness. It is therefore more comfortable and stable in the mouth. It takes four to five appointments to manufacture and costs more than the lower end option.
