An inlay or onlay restoration might be utilized on teeth with minimal to average corrosion or damage. Teeth that have the requisite structure to support a restoration and doesn't need the added support of a tooth cap. Inlays and onlays are most often made from porcelain materials which closely resemble actual teeth and give a completely natural and organic look when combined into the existing tooth framework.
The lone discernible difference between an onlay or inlay restoration is the size of the restoration. The inlay can only be placed in the centre of a tooth and only extends from the back of the tooth to the front of it. The onlay can be used just like the inlay, but, it is much more extensive covering more affected area, and being able to cover damaged segments of a tooth as well. The great benefit of an indirect restoration is that less natural tooth structure has to be extracted in preparation phases and the indirect restoration is made to fit within the existing framework of the tooth.
The procedure for an onlay or inlay filling can be completed over three dental health appointments.
Through the initial visit, the damaged tooth along with the region around the tooth will need to be given local freezing and in order to prevent any materials from falling into the mouth, a rubber dam has to be inserted. Then the tooth can be correctly evaluated and the area can be prepped by taking away any older fillings or any decay. Once remodeled and cleaned, the oral health care provider may begin making impressions to be given to a dental workshop to assemble the new filling. Lastly, the individual will be given a temporary acrylic restoration to allow them to carry on regular behaviors.
After about a week, the new restoration will be finished and the fitting can occur. The damaged tooth and adjoining area will have to be numbed again and a rubber dam needs to be placed. When ready, the provisional filling can be removed and the brand new restoration can be bonded to the tooth. The bite will be re-evaluated and the surfaces of the tooth will be polished.
The final visit should take minimal time and simply consists of inspecting the bite, the movement and capability to floss around the new filling, and to make certain all the exteriors are smooth.
