Orthodontic Treatment in Patient with Bilaterally Missing Maxillary Canines
Keywords:
Orthodontic treatment, Missing maxillary canines, Substituting maxillary first premolarsAbstract
Congenital absence of permanent maxillary canines is a rare condition. Both genetic and environmental factors can cause the failure of tooth development. Maxillary canines play an important role in creating a smile and good facial esthetics. Moreover, they support the dentition during lateral movement creating occlusal stability. This case report presented a 22 years old Thai female patient with an upper anterior spacing of the teeth. Oral examination and radiographic findings revealed the missing maxillary canines bilaterally. The patient was diagnosed with skeletal Class II malocclusion. This case report described the orthodontic treatment by substituting maxillary first premolars for missing maxillary canines to eliminate space. After the treatment, a stable occlusion with a satisfactory facial profile and functional excursion without interference was achieved. These results indicated that substituting the maxillary first premolars for the maxillary canines is an effective option in treating patients with missing maxillary canines.
