PurposeThe aim of this study was to evaluate the effect of pre-surgical infant orthopedic treatment (Hotz plate) and type of palatoplasty on the dental arch relationship and the dental arch morphology of unilateral cleft lip and palate (UCLP) patients.Materials and methodsSeventy-four children with UCLP were divided into three groups. One group had undergone one-stage palatoplasty without Hotz plate (OSP w/o H), the second had undergone one-stage palatoplasty with Hotz plate (OSP w/H), and the third had undergone two-stage palatoplasty with Hotz plate (TSP w/H). We evaluated the dental models which were taken during initial examination at our orthodontic clinic, using the Goslon Yardstick, the 5-year-old index, and dental model analysis.ResultsRegarding both indices, there were no significant differences among the three groups. However, the dental arch width between maxillary deciduous canines in OSP w/H and TSP w/H was significantly greater than that of OSP w/o H. The dental arch width at the maxillary deciduous second molars in TSP w/H was significantly greater than in OSP w/H and OSP w/o H.ConclusionDental arch relationship in UCLP patients was not influenced by the type of palatoplasty and the use of pre-surgical infant orthopedic treatment. Our results suggest that pre-surgical infant orthopedic treatment results in the increase of anterior dental width, whereas two-stage palatoplasty is significantly effective for increasing posterior dental width in UCLP patients.
