Fig. 26. Having prepared the cores of 2.4, 2.5 and 2.6 so that they can receive a temporary palladium-alloy periodontal prosthesis and Isosit facets to immobilize the teeth, which have a worsening 2nd degree mobility, a mucoperiosteal flap is sculpted and the circumferential palatal bone defects of the aforementioned teeth are exposed.
Fig. 27. X-ray of the mesial and distal palatal bone defects of 2.4 and 2.5 and the bone defect mesial to 2.6.
Fig. 28. The Interpore 200 implant is set in the bone defects and shaped.
Fig. 29. To facilitate the work, a stitch was applied to keep the palatal flap out of the way.
