A 25-year-old patient complains about a cosmetic defect in the frontal part of his upper jaw on the left. Objectively: the 23 tooth is pulpless. The filling restores vestibular-approximal surface of the tooth crown by 1/3, it is stable, closely fits within cavity walls, its colour doesn't match the colour of the tooth. The tooth itself has changed its colour, its percussion is painless. What is the optimal prosthetic construction for this patient?
