Congenital Missing of Maxillary Lateral Incisor and Rehabilitation in Unilateral Cleft Lip and Palate Parients

펼치기

Cleft lip and palate is one of the most prevalent congenital craniofacial anomalies, and it commonly has greater incidence of dental abnormalities in number, size, shape, and eruption of teeth. Maxillary lateral incisor is the most frequently affected. The aim of this study is to analyze the prevalence of congenital missing of lateral incisor in cleft side and non-cleft side in unilateral cleft patients who were treated in Pusan national university dental hospital. Radiographs and records were reviewed to find the relationship of missing tooth and cleft side, maintenance of maxillary lateral incisor, rehabilitation method. The ratio of congenital missing was 50% in cleft side and 18.75% in non-cleft side. The ratio of extraction after bone graft was 62.6% in cleft side and 31.25% in non-cleft side. The result suggested that since the ratio of maintenance of maxillary lateral incisor is low, early extraction can be considered in some cases.
