The universally accepted surgical approach for the extraction of the impacted/dystopic third lower molars makes use of several variants of L-shaped incision followed by the complete closure of the wound. Healing of the bone wound by primary intention becomes impossible in the cases of pre-existing chronic inflammation, extensive surgical injury, and inadequate blood clotting. The condition under consideration is associated with the 30% complication rate. Aim. To ensure controlled healing of the bone wound after extraction of impacted/dystopic third lower molars. Material and methods. The retrospective analysis of the outcomes of the surgical treatment of retention and dystopia of the third lower molars included 445 patients and covered the 2 year period. The results of the analysis were used to describe and illustrate by clinical examples the modified method for the healing of the bone wound resulting from the extraction of the impacted and dystopic third lower molars. Results. It was shown that the surgical treatment of retention and dystopia of the third lower molars with the help of the most extensively used variants of the L-shaped incision is associated with the 20—20.5% rate of perioperational complications that usually develop as the consequence of the «contaminated» wound. The proposed modified method of the surgical treatment of retention and dystopia of the third lower molars makes it possible to control the wound process by second intention avoiding the septic inflammation stage. The number of predictable complications associated with the application of the proposed method does not exceed 5% which corresponds to the «clean» wounds.
