Female patient, 47 years old, smokes 2 cigarettes a day. Sought treatment for an infection in tooth 21 which had caused the partial loss of the vestibular cortical bone. The tooth was removed and this was followed by reconstruction with bio-material and membrane in an attempt to preserve the stability of the soft tissue as much as possible and at the same time provide support at a coronal level. Due to the ease of access by the patient, hyaluronic acid in a gel form, with a concentration of 0.2% was prescribed 3 times a day for 10 days. The images below show the healing process at 5 days and 8 days after surgery. In this case, it is highly relevant to note that although the membrane is exposed, the epithelisation of the tissue is progressing at an excellent rate. This is an added value of hyaluronic acid: it aids the healing process and can therefore minimise the damage associated with exposure of the membrane once it is exposed.
