Intra-Oral Three Dimensional Scanning for Assessment of Surgical Outcome in Patients with Unilateral Cleft Lip and Palate
type: CreativeWork
description: Background: Cleft lip and palate is the most common congenital craniofacial anomaly. Orofacial clefting (OFC) presents as a heterogeneous group of disorders affecting the lips and oral cavity. Treatment involves a multidisciplinary team working with a high burden of care.Evidence is lacking regarding the optimum timing of lip and palate repair. Audit records are part of clinical governance, collected to monitor quality of care, but they can also be used for research purposes to generate an evidence base for best treatment protocol. Surgical outcome indices can be scored from audit records. The World Health Organisation (WHO) recommends study models to be taken pre-surgery and at 5, 10 and 18 years of age. The impression-taking process can be upsetting to the child and result in a failure to comply (Clark et al., 2007).Plaster study models can be scanned to create indirect three dimensional (3D) digital models and dental arches can be scanned directly using an intra-oral 3D scanner. The latter technique eliminates the need for impression taking but has not previously been investigated in cleft care.Aims: This prospective study aimed to examine the reliability of intra-oral 3D scans as an alternative to study models in assessment of dental arch relationships in a sample of 5-21 year olds with unilateral cleft lip and palate (UCLP).A secondary aim was to obtain patient and parent/carer feedback regarding acceptability of dental impressions and intra-oral 3D scans.Hypotheses (null): There is no difference in the reliability of scoring dental arch relationships using the GOSLON and MHB indices on plaster and digital 3D study models.There is no difference in patient / carer acceptability of routine dental impressions and intra-oral 3D scanning.Materials and Methods: Forty-six patients with UCLP attended the data collection clinic. Three patients withdrew as they did not wish to have routine dental impressions taken therefore 43 underwent routine dental impressions and int…
