Implant Procedure - Final Step - Fitting the Crown

This is the final step of the procedure.

A few weeks after the impressions usually about 2 weeks you will be asked to come back to have the final fit of the crown. During this appointment the clinician will try in the crown or bridge that has been sent back from the laboratory. They will initially just try it in and ensure it doesn't need any major changes. If they are happy with that then they will proceed to either cement retain the crown or to screw it in to permenantly place it.

The clinician will then check the bite and ensure that you are fully happy with it. Once everyone is satisfied you will be then finished.

Implant Procedure - Step 3 - Taking Impressions

This is the stage that will begin the procedure for making the crown to finish the implant.

Firstly, the implantologist will select an impression tray that matches your personal mouth size so it is the most comfortable.

Following this, the implantologist will place a special abutment into the implant which the impression will go round and show the laboratory exactly how the implant has been placed and give them a good idea on how to make the crown.

Then, they will have their nurse mix the impression material and place it into the tray. The nurse will then pass that to the implantologist and place it into your mouth. This is uncomfortable for many patients but the best thing to do is just breathe through your nose and focus on your breathing and not whats going on.

After this, they will unscrew the abutment so that the impression comes out. They will then send this to a laboratory where they will make the crown to fit on your implant.

Implant Procedure Step 2 - Placing the implant - Part 2

Once the pilot hole has been made then the implantologist will use drill pieces of increasing sizes to slowly made the hole bigger. This allows the implantologist to slowly increase the length and width until they are happy with the size.

During the increasing sizes a thread will be made in the bone so that the implant will be able to be screwed in easily. Some implants can be self-tapping which means that they create there own space to fit.

Once the implantologist is happy they will often place a direction indicator in the pre-made hole this is just to assess what direction that the implant will be. They may also take x-rays with drill pieces in the hole as they are going along this is to make sure that everything is going as best it can and so that they can measure accurately.

Once they are happy with the size they will then screw in the implant. The implantologist here prefers to use a little wrench a do it by hand as he feels he gets the best results that way. However, some implantologists will use a machine that measures everthing for them.

Implant Procedure Step 2 - Placing the Implant Part 1

This is the stage that the actual implant placement will take place. This can be from a week after the investigation to a few months (if there has been an extraction).

This is quite a lenghty appointment. Usually, we will book an implant for 3 hours and it takes 30 minutes to set up for the procedure. However, don't be put off by the length of time that the appointment is sometimes it can take a much shorter time it is just given to ensure there is no rush. The procedure is a very stop start procedure. This means that the implantologist will work a little then stop for a bit; possibly to take x-rays or prepare for the next stage, and then continue to work.

During the placement the Implantologist will start off by creating a space for the implant to be placed into. This means that the implantologist will begin with a pilot drill to give a starting point as to where the implant will be placed. If a surgical guide was made then this would be used to accurately place the pilot hole.

Implant Procedure Step 1 - Investigation

The initial stage for having an implant done is the investigation. This stage is where the implantologist will go through options with you, take x-rays and photographs and start to plan exactly where the implants will be placed.

During this stage sometimes the implantologist will request that you have a 'surgical guide' made. This is like a denture that is clear and has holes drilled into it. This assists the implantologist when placing the implants to improve accuracy.

They may also request that you have a CBCT scan done. This allows them to use special programs on their computers to plan and place implants. This means that they have an even better idea of the best place to insert the implant to ensure the highest success rate.

Fixed Retainers

These consist of a thin stainless-steel wire, which is permanently bonded behind the front teeth.

We usually fit your fixed retainers as soon as your braces are removed.

When you have this type of retainer you must try to be careful when brushing it and ensure you clean it thoroughly.

Like the other two types of retainers these serve the same purpose to help keep the teeth in the same position that they have been moved to.

Essix Retainers

These have the same function as the Hawley retainer to ensure the treatment of braces in not reversed after they are removed.

However, these are usually favoured due to them being made of a clear plastic and are more aesthetically pleasing.

They also cover the entire arch of the teeth not just portions like other retainers.

Hawley Retainers

The first that I would like to have a look at is the Hawley retainer.

This retainer is the most well-known retainer. They are usually made of an acrylic base with a bendable wire that will surround the front teeth to correct them.

It was named after its inventor Dr Charles A. Hawley.

It is used to ‘tweak your teeth and keep them in place so the procedure is not reversed after braces have been removed.

Retainers

Here at Provident Dental we provide three different types of retainers. They are the Hawley, essix and fixed retainers. Over the next four posts I will explain each retainer individually. First, I would like to just explain a little in general.

What are retainers?

A retainer is a custom-made, removable or fixed appliance that helps teeth maintain their new position after braces have been removed. Retainers can also be used to treat minor orthodontic problems

What do we do here and why?

Here at Provident Dental we do all sorts of orthodontic cases from minor ones that can be fixed using a retainer to full comprehensive brackets. We do this with the overall aim to improve a patient’s wellbeing. The aim of orthodontics is to not only better the patients bite and teeth but to also improve their general self-confidence and make them feel better about themselves.

Come in and Dr Mostofi will examine your bite and see which suits you best.

Also remember if you loose or break your retainer you will need a new one as soon as possible to ensure the treatment isn't reversed.
