Abstract
The aim of this study was to define and analyze the reproducibility of occlusal relationships according to the results of occlusogram in jaw closure using quantitative analysis of occlusion in adult patients with congenital cleft lip and palate before and after their prosthesis with different versions of dentures and types of their constructive features.
 Materials and methods. The study was conducted on 37 patients with congenital cleft lip and palate, 11 (29.73 %) of whom had right-sided clefts, 11 (29.73 %) – left-sided and 15 (40.54 %) – bilateral.
 The number of occlusal contact points was measured for all patients before the treatment and after the orthopaedic rehabilitation.
 Research results. Significant differences were found between the number of occlusal contact points before (unusually small number) and after orthopaedic treatment (significant increase), regardless of the type of cleft (p<0.001). Such conditions in the oral cavity significantly complicate the tactics of orthopaedic rehabilitation, which affects the need to find more complex options for combinations of fixed and removable orthopaedic structures.
 Conclusion. Based on the conditions and objectives of this study, the application of the basic principles of a multidisciplinary approach determine the possibility of rehabilitation of such patients by orthopedic methods by making different versions of orthopedic structures. Adequate and high-quality prosthesis for defects and deformations of the teeth rows and occlusion in patients with CCLP leads to improved occlusal relationships and increase in the number of occlusal contact points.
Highlights
Congenital cleft lip and palate (CCLP) ranks second in the structure of antenatal injuries and are among the most severe malformations of the maxillofacial area, which leads to significant functional and aesthetic disorders [1, 2]
The results of determining the occlusal contact points of patients with CCLP before and after the orthopaedic treatment, depending on the design of prostheses are given in Table 1 and Fig. 4

Summary
Congenital cleft lip and palate (CCLP) ranks second in the structure of antenatal injuries and are among the most severe malformations of the maxillofacial area, which leads to significant functional and aesthetic disorders [1, 2]. These defects arise in about 0.82–2.1 per 1000 live born babies in different countries of Europe and North America [3, 4]. Computer programs are used to quantify the features of contact points, which may not always be affordable for patients with insufficient income, and especially for patients with pre-existing dental anomalies such as CCLP [13, 14]
