Abstract

Studies have claimed that the maxillary arch dimension of unilateral cleft lip and palate (UCLP) patient is significantly smaller than normal patient. Multiple factors (both congenital and post natal treatment factors) are believed to have an impact on the treatment outcome (maxillary arch retardation) of UCLP patient. The aim of this study was to evaluate the effects of multiple factors on the treatment outcome by assessing the maxillary arch dimension of UCLP Children. Eighty-five Malaysian UCLP children were taken who received cheiloplasty and palatoplasty. Laser scanned 3D digital models of UCLP subjects were prepared before any orthodontic treatment and bone grafting at 7.69 ± 2.46 (mean± SD) years of age. Intercanine width (ICW), intermolar width (IMW), and arch depth (AD) measurements of maxillary arch were measured with Mimics software. Multiple linear regression analyses were used to evaluate the association between multiple factors (gender, UCLP type, UCLP side, family history of cleft, family history of class III malocclusion, techniques of cheiloplasty, and techniques of palatoplasty) and maxillary arch dimensions (ICW, IMW, and AD). P value was set at 5%. Significant association was found between 2 techniques of cheiloplasty and ICW (P = 0.001) and also between 2 techniques of palatoplasty and ICW (P = 0.046) of maxilla. No significant association observed in IMW and AD in relation to all other factors. Modified Millard techniques of Cheiloplasty and Bardach technique of palatoplasty had unfavorable effect on the treatment outcome by assessing the maxillary arch dimension (ICW) using laser scanned 3D digital models in Malaysian UCLP children.
