The plastic inlay is a kind of "white filling" that is cured outside the mouth and then glued into the relevant molar.
What are the preparations for treatment?
The dentist will check whether the molar in question is suitable for a plastic inlay. Usually it will be a molar that has previously been filled with an amalgam filling. If this amalgam filling is not too large and there is not much tooth decay underneath, the molar is suitable. There must be enough intact tooth tissue left to glue the inlay to.
Is the treatment painful?
Just like when applying a new filling, this treatment can be painful. Pain experience is very individual, you decide whether or not you want to be anesthetized. If you don't need to be anesthetized for a normal filling, then usually not for an inlay either.
How often do I have to come to the practice?
You can make a plastic inlay in one session. It will be a somewhat longer appointment, because the inlay is cured outside the mouth, you have to wait for that.
First, the old restoration will have to be removed. The old (usually amalgam) filling is drilled out. All sharps are extracted with a large extractor, so that you do not swallow it. When the old filling has been removed, the remaining part of the element is inspected for damage, discoloration and other inaccuracies, all of which are also removed. Then the molar is ground in such a shape that the inlay can still be removed even if it is hard. Sometimes cofferdam is applied at this time of the treatment.
When the molar is completely clean, a soft plastic is placed in the molar and modeled. This plastic then has a little time to cure until it is rubbery. The still flexible plastic inlay is taken out of the tooth and placed in a special box. In the box, the inlay is cured with light. After curing, the inlay is no longer rubbery and malleable, but rock hard. The inlay is fitted, finished outside of the mouth and then glued into the tooth. After the adhesive layer has hardened, the inlay is checked for height and polished for high gloss.
Which additional objections can I expect?
Maybe some pain, usually not much. Because the inlay is cured outside the mouth, most shrinkage also takes place outside the mouth. A plastic inlay therefore gives less pain on the tooth due to tensile stress than a composite filling.
The result is a healthy looking tooth.
The same applies to this restoration: the edges must be kept clean, so flossing every day is a must.
Alternatives and pros and cons
- A "normal" composite filling;
- Porcelain inlay.
Advantages of the plastic inlay:
- Cheaper than porcelain;
- Requires only one treatment;
- Gives less tension to the element than a composite filling;
- The end result is harder than a composite filling.
Disadvantages of the plastic inlay:
- Wears harder than porcelain;
- More expensive than a composite filling.
Indirectly made workpieces
Indirectly made means that the dentist makes a dental impression after certain pre-treatments and sends it to a dental technician, who then makes the piece of work that you get into your mouth. More dental visits are therefore required for such workpieces.
Examples of indirectly created workpieces:
- Porcelain facing;
- Porcelain inlay;
- Etching bridge;
