Replacing all teeth

If you are missing or need to remove all the teeth in one or both jaws, dental implants may allow you to have a fixed arch bridge complete.

Sustitución de todos los dientes / all on four

As an alternative to using a complete denture (if there is enough bone or bone augmentation procedures, enough bone can be grown), multiple dental implants can be placed through the jaw to support a fixed bridge. This procedure is similar to those described for multiple or single-tooth dental implants, only that it requires careful diagnosis, planning and coordination before treatment begins.

This attention to detail will ensure the safe placement of an adequate number of dental implants in positions that will allow the dentist to manufacture a bridge that meets their needs and expectations.

The number of dental implants needed for a fixed arch bridge completely varies depending on your particular anatomy, the opposing teeth, the type of bridge you want to be placed and the number of teeth that you want or need to replace with the prosthesis. An arch full of dental implants can be placed when all the teeth are already being lost in the jaw or jaw.

If you have the remaining teeth, you may need to remove them as a first step before dental implant surgery, or in some cases the teeth can be removed and dental implants placed immediately. If there are remaining teeth, you may have a temporary fixed bridge made by your dentist to help transition your own teeth to dental implants.

In this scenario (while dental implants heal), the provisional bridge remains in the place that allows you to chew, smile and talk, all without having to use a removable prosthesis.

The use of a temporary removable prosthesis is only suggested in case it is not possible to maintain enough teeth to support a fixed bridge while dental implants heal.

Usually, in order to have a good healing of the gums, you will be informed by your dentist to refrain from using the prosthesis for a period of time (usually two weeks) after the dental implants have been placed.

Although it should be mentioned that in recent years it has been proven that it is usually possible to place an arch full of dental implants and connect them to a fixed bridge (usually temporarily) in what is known as immediate loading, which means that the implants Dental are receiving the burden of chewing forces as soon as they are placed.

This new procedure is highly successful, but there are certain requirements for its success. This technique requires careful planning and coordination by your dentist and surgeon. As with all treatments you should discuss all your options and alternatives with your dentist and decide together what may be the best and most appropriate for your specific case.

What is an implant overdenture?

An implant overdenture is placed over a dental implant with several types of retainers that provide stability and retention of your entire dentures.

Dental implant overdenture is a complete prosthesis that is used to replace teeth in a complete arch when all teeth are missing. In essence, it is a larger version of the removable partial denture on assisted dental implants. The denture is placed under pressure achieving greater comfort and a better ability to chew. Dental implant overdentures are held in place by several dental retainers selected by your dentist to provide maximum retention and increased ability to chew.

The dental implant overdenture is removable to facilitate cleaning of the dental implant support structure. Overdentures of dental implants feel extremely comfortable and can be done in order to look like natural ones avoiding looking fake.

Presurgical prosthetic planning for overdentures on dental implants begins with diagnostic impressions to record the bite ratio in relation to your jaw and jaw, which is essential to suggest possible dentures for each patient.

These impressions helps to determine the correct positioning of the teeth in the new prostheses, as well as to confirm the optimal location for each dental implant. Also used to ensure the correct appearance and bite.

Often, a template is produced from the diagnostic impression that is provided to the surgeon to assist in the orientation during surgery the placement of the dental implant

Very often, an upper overdenture will require the placement of more dental implants than a lower overdenture due to the different nature of the anatomy of the upper and lower jaws. It may also be possible to manufacture an upper denture without a palate, which may be a more comfortable option for some specific patients.

The particular need for an overdenture of dental implants may change and the decision of this treatment option must be made with your restorative dentist. Many patients can be benefit from the facial support provided by the extensions of the full denture design. The number and type of dental implants should be decided following a detailed discussion between you and your dentist, based on your personal experiences with your current dentures, a complete examination and a careful assessment.

Replacing several teeth

The replacement of several teeth can be achieved with any of the following treatment options:

  • Multiple dental implant of a single tooth.
  • Bridge over dental implants (fixed prostheses over dental implants).
  • Removable partial denture (DPR).
  • Fixed partial prosthesis (DPF).

Lost teeth can be replaced with multiple restorations of a single tooth (described in the replacement of a single tooth) or with fixed partial dentures (dental implant bridges). Bridges over dental implants replace lost support as a result of missing teeth, avoid the need to wear adjacent teeth and do not require a dental implant for every missing tooth. It should be noted that the gum tissue and the underlying bone must have the characteristics required to place the dental implants.

Dental implants are placed in strategic positions to replace lost teeth. When dental implants are stable and ready to support the load, the abutments can be attached to the dental implants that will join the final bridge to the prosthesis.

An impression is made and a record of the contours of the abutments or the position of the upper part of the dental implant is made. The dental implant bridge is then manufactured and held in place with screws or cement.

A bridge of dental implants is not susceptible to decay, but it could develop complications if oral hygiene is not maintained. It is recommended to be evaluated periodically, the interval depends on the conditions of the remaining natural teeth and the bridge over the dental implants. Porcelain reconstructions may be susceptible to a low incidence of porcelain fracture. Patients with considerable significant functional forces (such as bruxism) may require more solid chewing surfaces.

Removable partial dentures assisted by dental implants (DPRI) use a few select implants, located in strategic positions and connected to the superimposed denture by means of a bolt screwed into the dental implant.

These key implants can eliminate unsightly hooks, reduce the display of metal parts in the DPR and increase the amount of support, stability and retention of the final restoratio

With the proper design, a DPRI can be modified to add any teeth that need to be extracted in the future. Once the dental implants are stable and ready to receive the load, the abutments can be fixed to the dental implants. The abutments can be used individually as bolt retainers or as part of a larger superstructure, manufactured in the laboratory with various clip-type retainers (or retention elements) that connect the DPR. An impression of the teeth and retention elements is taken to allow the laboratory to manufacture the final prosthesis.

The retention elements can be processed in the laboratory or in a clinical procedure that is performed next to the chair. Restoration by dental implants should be routinely evaluated at intervals that will depend exclusively on the conditions of the remaining natural teeth and the DPR on dental implants.

Denture teeth and retaining elements will be subject to wear and should be replaced when necessary. Usually, denture teeth will last for years, but most of the retention elements need to be replaced every six months or more.

Replacement with a conventional removable partial denture (DPR) is indicated in patients who agree to have a restoration that is NOT permanently attached.

all on four

The patient must withdraw this restoration daily and thus facilitate access to perform oral hygiene of the remaining natural teeth and the prosthesis. The DPR is made of a metal frame, teeth of the denture and acrylic.

Some patients do not like the appearance of the hooks (metal arms) that connect to the remaining teeth to retain the prosthesis, the exposure of the metal frame portions, the teeth of the denture and the acrylic. Over time, it is often necessary to replace worn teeth of the denture, as well as overflow or fill the prosthesis to maintain a proper fit to the gums.

The main advantages of a DPR are minimal preparations of adjacent teeth (much smaller than for a bridge), replacement of missing teeth, aesthetic replacement of the lost volume of gum and bone, lower expense and easy access for oral hygiene. With a proper design, a DPR can be modified to add any missing teeth that need to be extracted in the future.

Replacement with a fixed partial denture (DPF) or bridge requires reducing two or more adjacent teeth to make crowns that will be connected to each other through a false (prosthetic) tooth suspended between them. A fixed bridge increases the functional forces exerted on the support teeth and complicates the use of dental floss between the teeth.

The number of natural teeth that require reduction depends on many factors such as the number and area covered by the missing teeth, the location in the jaw and the state of the teeth themselves involved. Conventional bridges may require replacement if supportive teeth develop decay or parodontal disease.

All on 4 Treatment


If you have lost all your teeth, conventional dentures are in many cases an unsuccessful solution. These types of dentures that can sometimes be painful, uncomfortable and unstable, make it difficult to chew and you may have to stop eating many of the foods you enjoyed. However, modern dentistry has solutions that fit a variety of needs. The All-on-four treatment option is one of them.

An effective treatment option

Concept of All-on-four treatment

The concept of All-on-four treatment replaces the missing teeth with a complete dental bridge supported only by four dental implants. By needing fewer implants, the total treatment time is reduced. The exclusive All-on-four solution also guarantees greater bone stability, reducing the need for bone grafts.

Under normal conditions, your dentist will be able to place the provisional teeth the same day of the intervention. These provisional teeth look very similar to natural teeth and you can live a normal life immediately after surgery.

After a few weeks of healing period your dentist can place the definitive bridge. Your quality of life will improve and you can start enjoying your favorite foods again.

Tratamiento All on 4 implantes dentales

Dental implants offer you many advantages

A cost effective solution. The new teeth only requires four implants per maxilla. By using fewer implants, the cost is reduced

Less need for bone grafts. The special inclination of two of the implants guarantees a secure and stable anchorage of the dental prosthesis so that bone grafts are no longer necessary.

Treatment and shorter healing period. The prosthesis can be anchored to the implants just after insertion. It is not necessary to wait for a healing period between surgery and tooth placement.

Flexible options You can choose the definitive prosthetic solution that best suits your needs, either a fixed option (which offers greater durability and better chewing function, but cannot be removed) or a removable option (which can be removed for easy cleaning)

Scientifically tested and documented. The All-on-four concept is supported by the good clinical results of studies in which four implants have been inserted to support a full arch prosthesis.
