It is quite difficult to determine the correct treatment procedure to success in the treatment of dental trauma cases in the form of crown fractures in teeth with immature root formation.

This case report presents the treatment of the complicated crown fracture with the open apex of the tooth of a delayed admitted patient, with modified polyethylene fiber post.

This novel treatment type may promise favorable outcome and can be used in such cases.


In this case, it was aimed to restore a traumatized permanent incisor with open apex using a modified polyethylene fiber post after amputation as well as to present a four-year long term follow-up. A healthy 10-year-old boy was referred with a complaint of pain caused by tooth number 11. The patient fell and broke his upper incisor ten days ago and no treatment was done before. Total amputation was carried out after clinical and radiological examination. The exposed root pulp was covered with BiodentineTM (Septodent, Saint-Maur-Fosses Codex, France). Glass-ionomer cement (Fuji IX extra, GC Corp., Tokyo, Japan)  was placed on the BiodentineTM, and after a 3-month follow-up, polyethylene fiber post (Ribbond, Seattle, WA, USA) was placed in the crown since healing was observed in the relevant tooth. The restoration was completed with composite resin (Clearfil Majesty Esthetic Kuraray, Osaka, Japan). Four years later, radiographic examination revealed completed root formation and complete root obliteration. Clinical examination revealed favorable esthetic and functional outcome. Traditional treatments can be modified in order to obtain long term clinical success. Polyethylene fiber post can be used as an alternative method to root canal therapy in complicated crown fractures in teeth with immature root formation due to the advantages such as the possibility of modification according to the crown, aesthetics, easy application, and supporting the vitality of the tooth.
