Placing a crown on the rod or screw (a.k.a. the abutment) of a dental implant is considerably different from attaching it to a natural tooth. In some instances, establishing proper contact strength with a dental implant restoration may be challenging for the dentist performing the procedure. So the best way to achieve success in predictable and quick fashion is by considering the different clinical circumstances or conditions that may be involved during this restorative procedure.
When the dimensions of the restoration are larger or smaller than the space that accommodates it, an interproximal contact develops with the adjoining teeth. Plus, the restoration may not fit correctly. So if the restoration is too small, the contact will be more open and you will not experience any resistance when flossing between your teeth. Conversely, when it is too large, flossing will be extremely difficult. The dentist’s goal is to create an interproximal contact that displays the proper amount of contact strength and has a proper location.
When crowns are placed on natural teeth, the adjoining teeth tend to shift in order so that the restoration can be accommodated. Although the restoration will center itself in the placement space, the teeth will still be displaced. Sometimes the contact the restoration makes with the adjoining teeth will be made heavier on one side or the other in order to achieve success and accommodate any movement of the restoration. There is no cause for worry as the pressure will eventually even out.
On the other hand, when crowns are seated on dental implants, the restoration will not move despite the fact that the adjoining teeth do. Consequently, the strength of the contact on both sides will need to be independently adjusted to ensure a proper fit. Additionally, the oversizing of the crown should be slightly smaller than that of natural teeth. The dentist will take care to ensure proper contact strength by not making adjustments to one side until the other has been properly tested.
In most cases, a local anesthetic will be administered when a crown is attached to a natural tooth but is not necessary when it is placed on the implant abutment. As with other dental procedures, the effect of the anesthesia will usually last longer than what is involved for the neighboring teeth to adjust to the contact pressure.
