Porcelain chips again around the access hole of PFM 1.5 years post 2nd cementation.  The dense bone at the crest (*) cannot explain why the abutment is not loose, since it remains incompletely seated (>).  As it was trimmed short, an angled abutment is used (Fig.28).  The coronal end is lingual, while #9/24 is edge to edge.  The lingual aspect of the coronal end of the abutment is heavily trimmed to reduce bulkiness.  To prevent chip, Zirconium crown will be fabricated in spite of the fact that it does not match the PFM of #8 (potential shade discrepancy).
