Fig.
1 Case at beginning. A chamfered mucoperiosteal flap will be sculpted on
the inside to eliminate the periodontal pocket and gain access to the bone
defects; then, following curettage and scaling in the mesial bone defect
at 1.7, osteoplastics will be performed with an osteotribe. |

cannot be treated only with resective surgery and mesially at 2.1 for treatment
of a hemiseptum. |

performed with single stitches. After six months a cast gold core will be
created in 1.7. |

piece, is constructed to check and record the necessary occlusal and gnathological
data. |
