Mrs. Zhu is afraid of dental work. One of her bottom right molar teeth (#31) has been missing for long time. Witnessing the beauty of guided implant surgery of her husband, she agrees to have the same one. The latter requires 2 preparations: CT and impression. CT (Fig.4,5) helps choosing a proper-sized implant (I, green), relative to the underneath nerve (N). C: future crown.
