A patient presented to our office complaining from the space defect between her lower second premolar and the lower second molar.
Upon examination, it was elaborated that the first lower molar has been successfully extracted 20 years ago, hence, the lower second molar tended to tilt mesially narrowing the sufficient space needed to do an implant followed by a zirconia crown for that space.
After discussing the possibilities with the patient, we decided to go for a quadrant rehabilitation, where we will rebuild the lower second premolar and the lower second molar and prepare them to receive two indirect lithium di-silicate overlays, and that the lower first premolar will be prepared to receive a full zirconium crown.
It was an out-of-the-box decision at the time considering the gap formed between the lower second premolar and the lower second molar, but a semi-flat occlusal table was considered when designing the ceramics.
And now I can happily share the static results we got after about 18 months of follow-up
