Our Dental Implant Procedures

A dental implant is an artificial tooth root made of titanium that is placed into your jaw to hold a replacement tooth or bridge. At O Brien, Molloy & Delaney, one of Irelands largest specialist dental practices, we are experts in the placement and management of dental implants. Over the years we have successfully placed thousands of dental implants, from single units to full mouth rehabilitation

Procedure

Dental implants are titanium screws that are surgically placed in the jawbone and are used to hold a replacement tooth or bridge. Dental implants may be an option for people who have lost teeth due to caries, periodontal disease, trauma or other reasons.

The dental implant procedure is done under local anaesthetic usually and is a painless procedure. Sedation is available for patients who are nervous. Some minor pain and discomfort are expected for a few days after the surgery.

During the healing phase, a temporary tooth or denture is usually worn to replace the missing tooth. This gives a good aesthetic and functional solution during this period.

Healing

During the healing phase, a temporary tooth or denture is usually worn to replace the missing tooth. This gives a good aesthetic and functional solution during this period.

Once placed, the implant needs approximately 3 months to fuse with your bone and become integrated. Once the implant has integrated, impressions are taken to allow a crown or tooth to be made which is then screwed into the implant itself

Occasionally it is possible to extract the tooth and place a dental implant on the same day – an immediate implant. This depends entirely on the clinical situation and our specialists will discuss this with you at your consultation.

Bone Grafting

Dental implants need to be placed into adequate and healthy bone. Once a tooth is extracted the bone that was holding the tooth in place starts to resorb or atrophy.

This can happen quite quickly and can be pronounced over the first 3-6 months. This reduces the bone available at the site.

If a tooth has been missing for some time there may not be enough bone to hold the implant. In such a scenario a bone graft is placed at the site to augment or build up the available bone.

Depending on how much bone has been lost, the bone graft may need to be placed in a separate procedure prior to implant placement.

This bone graft is then left to heal and mature for 4-6 months prior to placing the dental implant. The bone graft materials usually come from an animal or human source.

Socket Preservation

When a tooth is extracted the bone that holds in the tooth quickly resorts. This can lead to a situation where there is not enough bone to hold our implant. In order to counteract this, we often place a bone graft material into the empty socket just after the tooth is removed.

This bone graft then matures and turns into native bone over the following few months. This then allows us to place the dental implant in good bone at a later date.

This technique is called socket preservation as we are preserving the original dimensions of the bone in the area.

Cause

A sinus bone graft or augmentation procedure is when a bone graft material is placed into the sinus cavity in the upper jaw.

Everybody has air sinuses located within the bone in the upper jaw, above the back teeth. The roots of these teeth often protrude into this cavity.

If these teeth are removed, the sinus cavity can actually enlarge and expand into the site where the teeth were.

This then reduces the height of bone available to us to place a dental implant.

Treatment 

The solution then is called a sinus bone graft. A small access hole is made through the bone over the sinus.

This allows us to gently lift the thin layer of tissue or membrane that lines the inside of the sinus cavity.

Bone graft material is then packed into the space created underneath this membrane.

The area is closed up and allowed to heal for several months. Once the bone graft has matured and new bone has formed, we can then place our implants into this new bone.

Solution

Sinus grafting makes it possible to safely and successfully place implants in the back of the upper jaw where there is not enough bone available initially.

If the is a reduced amount of bone available but still enough to hold our implant, it may be possible to do the implant and the sinus graft on the same day.

This a called an internal or simultaneous sinus lift. In more severe cases where there is minimal bone available, then the sinus lift bone graft is carried out as a separate procedure, an external sinus lift.

Our surgeons will discuss the treatments options that are best suited to your case.

The dental implant is a titanium screw placed in the jawbone. This implant or screw is then used to hold a crown or tooth.

Once the implant has successfully integrated into the bone, an impression is taken of that implant which allows our laboratory to make a porcelain crown or tooth.

Here at O’Brien Molloy & Delaney, we use an intraoral scanner that takes a virtual ‘’impression’’ of your mouth and the implant.

This information is then digitally passed to the dental lab. This technology has done away with the old impressions of the past where a putty material was used to take a record of the mouth, making it more comfortable for you.

Once the crown is returned from the lab, it is screwed into position on the implant underneath.

Single implants

A single implant is a dental implant used to hold a single tooth or crown.

Multiple implants

Where multiple adjacent teeth are missing in the mouth, multiple implants can be used to hold a ‘bridge’ or many teeth linked together.

This negates the need for natural teeth to be prepped or ground down, the traditional way to make a bridge using natural teeth.

Full arch implants – fixed and removable

In this scenario, a full arch of teeth, either upper or lower jaw, can be replaced with multiple implants holding a bridge or a denture.

This will require a minimum of 2 implants to hold a denture up to 6 implants to hold a full arch of ‘fixed’ teeth in the upper jaw
