Aim: The aim was to compare skeletal age of patients with unilateral cleft lip and palate and that of the control group of non-cleft patients. Material and method: The sample included 106 patients with unilateral cleft lip and palate and 111 non-cleft patients with good quality lateral cephalograms executed as a part of orthodontic documentation. To determine skeletal age the so-called CVM method (i.e. according to cervical vertebrae maturation) was used. Results: Patients with unilateral cleft lip and palate have significantly delayed skeletal maturation compared to the control group of non-cleft patients. Conclusion: Delay in the skeletal age in patients with unilateral cleft lip and palate should be considered when preparing the treatment plan; timing of interceptive therapy and invasive management (e.g. orthognathic surgery, insertion of dental implants, etc.) should be adjusted as they require precisely set finish of growth.

Aims: The study objective was to assess occlusion in patients after orthodontic therapy with fixed appliance and in untreated individuals. Material and method: The sample included 81 students of dentistry at Masaryk University Brno aged 22-30 (mean age 24.3 ±1.67). The first group included 42 individuals without orthodontic treatment, and the second group 39 people after orthodontic therapy. Both groups filled in forms and a questionnaire on symptoms of temporomandibular dysfunction (TMD), CPI index, and digital analysis of static and dynamic occlusion performed with T-Scan. Results: No differences were found in overall condition of periodontium, mobility of mouth opening, chewing muscles pain. TMD symptoms were more frequent in the group after orthodontic therapy – clicking on the right. In case of static occlusion forces were distributed more in posterior segment of dentition in patients after orthodontic therapy. In case of dynamic occlusion there was found no difference in the guidance in lateropulsion (group, anterior or canine guidance). However, in patients after orthodontic therapy a longer time of disclusion (i.e. the interval between the beginning of lateropulsal movement and the achievement of one of the mentioned types of guidance) was observed. Conclusion: Orthodontic therapy may influence some parameters of static and dynamic occlusion. To determine the changes we can use digital occlusal analysis T-ScanTM, or apply one of techniques of articulation grinding.
Aim: The authors’ objective was to prove or reject the hypothesis stating that in patients with cleft lip and palate agenesis in the lower jaw is more frequent. We monitored patients with the most frequent cleft defect, i.e. unilateral cleft lip and palate, and the most frequently missing tooth in the mandible, i.e. second premolar. Material and method: The sample included 160 patients with unilateral cleft lip and palate either on the left or on the right side. We recorded the side of the cleft defect, patients’ sex, and presence or absence of lower second premolar germ either on the left or on the right. The criteria included the patients’ age (patients born between 1999 and 2008), at least one good quality scan taken at the age 8–11, and unilateral cleft lip and palate that is not a part of a syndrome. Results: Out of the 160 patients, 146 (91.3%) had established lower second premolars, in 14 (8.7%) the teeth were missing (agenetic). In case of right side clefts, the missing lower second premolar was found either on the right side or on both sides; in case of the left side clefts, the missing lower second premolar was found either on the left side or on both sides. Conclusion: The results proved more frequent agenesis in the mandible, and show significant relationship between the cleft side and the side with missing lower second premolar.
