    Background/Purpose: Vertical root fracture (VRF) is a complication in endodontically treated teeth. This study aimed to assess the clinical outcomes of treatment of 6 VRF teeth with intentional replantation and root fragment bonding with 4-methacryloxyethyl trimellitate anhydride/methyl methacrylate-tri-n-butyl borane (4-META/MMA-TBB) resin. Methods: A series of 6 complete VRF teeth (one incisor, one canine, one premolar, and 3 M) were treated through intentional replantation and root fragment bonding with 4-META/MMA-TBB resin. Results: This study included 6 VRF teeth in 6 patients (one man and 5 women; mean age, 44 ± 8 years). All 6 teeth had VRF in the bucco-lingual direction and one tooth had concomitant VRF in the mesio-distal direction. The root thickness was classified as thick in all 6 teeth. Of the 6 VRF teeth, 4 had biting, percussion, or palpation pain, 4 had gingival swelling, 3 had sinus tracts, 3 had discomfort, and one had tooth mobility. Radiographically, 5 of the 6 teeth had periradicular radiolucent lesions, 4 of which exhibited complete regression and one of which exhibited nearly complete regression after root fragment bonding therapy. Because all 6 treated teeth exhibited sound function in the oral cavity after a follow-up period ranging from 33 to 74 (mean, 50 ± 15) months, the clinical outcomes were all considered to be successful. Conclusion: For a VRF tooth, in addition to tooth extraction, intentional replantation combined with root fragment bonding with 4-META/MMA-TBB resin is a successful treatment modality that can be used to preserve a complete VRF tooth.
