ABSTRACT
Objective:
To investigate the efficiency of CBCT in the diagnosis of impacted maxillary anterior teeth and the treatment effect of different guided eruption methods.Methods:
34 impacted maxillary anterior teeth in 30 patients were examined by panoramic films and CBCT, the dental crowns, root, eruption space and other related items were measured and compared between 2 examinations. 20 cases were treated by closed guided eruption and traction( CGET) technique, 10 cases by circumferential supracrestal fibrotomy and exposed traction( CSF-EE) , results were compared.Results:
CBCT was more effective than panoramic films in the revelation of tooth root bending, apical pore closure and eruption measurements(P<0. 05). 7-10 d after treatment 5 out off the 10 casses treated by CSF-EE showed different degrees of clinical crown elongation, poor gum appearance and low height of alveolar ridge as insufficient periodontal attachment. However, the treatment of CGET for 26 teeth (76. 47% of all cases) was highly successful and received very satisfactory re-sults, the rest 8 teeth (23. 53% of all cases) showed mediocre satisfaction.Conclusion:
CBCT can accurately display the position, shape, relation with adjacent teeth of the impacted teeth. Closed guided eruption and traction is more effective for the treatment.
