Replacing 4 Front Crowns — Correcting a Compromised Bite

A patient came in self-referred, worried — the provisional crowns on his four upper front teeth kept coming loose, and the teeth underneath had started to feel wobbly. That's an alarming thing to notice, and getting a second opinion rather than simply re-cementing the same provisionals again was the right instinct.

Diagnosis found the real cause wasn't the provisionals themselves — it was the bite. The teeth were taking more load than they were built to handle, which is exactly what makes a crown come loose and the tooth underneath feel unstable. So treatment wasn't just about making four new crowns; it meant working out how the bite needed to change so those teeth would carry weight safely once the new crowns were in, rather than repeating the same failure.

The final crowns were zirconia, layered with feldspathic porcelain and placed using the BOPT (Biologically Oriented Preparation Technique) — a preparation approach chosen for the condition of the remaining tooth structure and the surrounding gum tissue, not a default. Between the material, the preparation technique and the corrected bite, the goal was a result that holds up biologically, functionally and aesthetically — four teeth built to actually stay put, not just look right.
