They say success rate of periodontal surgery for smokers is significantly lower than that of non-smokers. This case was not also an exception. Knowing risks beforehand, I performed tissue regeneration surgery in the upper right 2nd molar and root coverage therapy in the upper right canine and 1st front tooth. The results of these operations were unsatisfying like lots of papers said, though implants and orthodontic treatment has been successful so far. It was full of meat as an egg.
