Clinical study on the closure of extraction wounds of partially soft tissue-impacted mandibular third molars.

Abstract

Closed healing by drain insertion after removal of partially soft tissue-impacted third molars produces less frequent postoperative dry sockets and/or alveolitis development than occurs with open healing of the surgical wound. In cases with a risk of alveolitis development (lack of oral hygiene, immunocompromised patients, etc), it can be avoided with the "kiddle effect" and related undesired complications by implementing closed healing with drain insertion.
