Resin-bonded ceramic onlays for retained primary molars with infraocclusion.

In some patients, primary molars with no permanent successor can be retained for an indefinite time; however, if occlusal relationships necessitate intraocclusal augmentation, cast ceramic onlays can provide an excellent solution. This paper reports the case of a teenager in whom two cast ceramic onlays were bonded with resin to retained mandibular primary molars, to create an esthetic and functional occlusion.
