Surgical crown lengthening may include the removal of soft tissue or both soft tissue and alveolar bone.
However these procedures are more cumbersome than surgical crown lengthening because of the necessity of a surgical and retention phase of clinical crown lengthening after orthodontic forced eruption, need for several session of fibrotomy to prevent the periodontal tissue from being pulled coronally together with the orthodontically moving root and relapse tendency.
After root canal treatment we extracted the tooth, clean the socket and reimplanted tooth again, but due to very low crown root ratio we adjusted the crown length during reimplantation to prevention of crown lengthening or force eruption afterwards.
Then filled % of the socket with hydroxyapatite that we prepared before and inserted the tooth inside the socket and adjusted the tooth up to the ideal length, it will prevent the crown lengthening in a crownless tooth.
