Abstract：Objective To evaluate the dental arch relationship of patients with unilateral complete cleft lip palate (UCLP) by comparing them with previous study and to provide theoretical basis on diagnosis, treatment plan design and team approach for patients with UCLP. Methods Totally 52 UCLP patients treated in the Department of Orthodontics in the Affiliated Hospital of Qingdao University during March 2013 to March 2014 were selected. The dental models of UCLP patients were categorized using Great Ormond Street, London and Oslo Yardstick (Goslon Yardstick) index. Compare the results with the Goslon Yardstick scores of Chang Gung Craniofacial Center, Hospital of Tokyo University and 6 Eurocleft centers reported in previous studies and make statistical analysis. Results Mean Goslon Yardstick score of UCLP treated in Affiliated Hospital of Qingdao University was 3.75±0.93;36.5％ patients had a Goslon Score of 4, and59.6％ patients were classified into poor and very poor categories. The results of our center showed significant differences from those of Eurocleft centers A, B, C, E and F (P ＜ 0.05), but did not differ significantly from those of Eurocleft center D, Chang Gung center or Hospital of Tokyo University (P＞ 0.05). Conclusion Dental arch relationship in patients with UCLP in the Affiliated Hospital of Qingdao University is poor, which is similar to that in Chang Gung Craniofacial Center, Hospital of Tokyo University and Eurocleft center D, but is poorer than the other fove Eurocleft centers.
