This developmental anomaly may cause clinical problems including estheticimpairment, which are mainly treated by endodontic and surgical treatments. There are a few reportsof conservative not invasive treatment of fused incisors teeth through restorative or prosthetictechniques. They are rarely reported in mandibular posterior teeth. This paper presents an unusualcase of fusion of 7 and 8, and also 9 and 10 teeth which was treated with a nonendodontic andnonsurgical conservative approach. Patient was a healthy18-year-old female with chief complaintof bad-looking teeth that in intraoral examination revealed the fusion of 7 and 8, and also 9 and 10teeth. The space between the mesial of the 6 and 11 teeth was reconstructed. Diastema betweenthe fused teeth was closed. A new lateral tooth was replaced between the fused teeth (7 and 8)and 6 tooth with direct fiber-reinforced composite. The space between the fused teeth (9 and 10)and also tooth 11 was partially closed. Gingival papillas were reconstructed using pink composite.The mandibular anterior missing teeth were replaced with rochett bridge. At the end of treatmentthe esthetic of the patient was improved. As the treatment was not invasive, major complicationsare not expected; however, there is potential for eventual long-term periodontal problems due topoor oral hygiene. Debonding of the rochett bridge may happen as well.Key Words: Fusion, incisors, non-invasive management
