RESUMEN
To evaluate the bite force (BF) changes in bilateral cleft lip and palate (BCLP) in contrast to the non BCLP children after ALT-RAMEC Facemask therapy.The prospective study was carried out on a total of 60 subjects of age 6 to 13 years in a tertiary care hospital; treatment group, 30 children with BCLP and control group, 30 children without cleft lip and palate. Each cleft patient was received ALT-RAMEC Facemask treatment and their BF assessed at 4 different stages. Bite force taken before treatment, immediately, 3 months and 6 months after treatment. Bite force of the control group was taken at baseline to compare with the treatment group to demonstrate the difference in BF values. Independent t test and analysis of variance were used to perform statistical analysis.There was a significant difference in BF between the treatment group (BCLP) 122.53 ± 8.64 N and the control group (non BCLP) 181.38 ± 18.84 N at baseline. After the Alt RAMEC protocol, changes in BF recorded over 3 and 6 months of therapy showed significant improvement. The mean values of BF at 3months and 6 months were 106.7 ± 9.3â N and 137.4 ± 9.5â N, respectively.Bite force was significantly improved after ALT-RAMEC protocol followed by facemask therapy in BCLP patients.

OBJECTIVES: To assess treatment outcome (transversal and sagittal dental arch relationships) and its determinants in complete bilateral cleft lip and palate (BCLP) evaluated with the modified Huddart-Bodenham scoring system and the BCLP Yardstick. MATERIALS AND METHODS: Multiple electronic databases were searched without time limitation. Randomized clinical trials, cohort and case control studies using BCLP Yardstick and/or modified Huddart-Bodenham system to judge treatment outcome of patients with BCLP were included. The Risk of Bias in Nonrandomized Studies of Interventions tool and Grading of Recommendations, Assessment, Development, and Evaluation was used. RESULTS: Of the 528 studies identified by the electronic search, only eight retrospective studies met the inclusion criteria and were included. A total of 12 cleft centers were represented. All treatment protocols differed and background information was underreported. The results for the BCLP yardstick showed that all except the centers in New Zealand had a mean score lower than 3, indicating good treatment results. However, these studies had a moderate to high risk of bias. The modified Huddart-Bodenham scores were negative in all studies. No further meta-analysis was done due to heterogeneity and high risk of bias. The quality of evidence was graded as very low. CONCLUSION: Results for the dental arch relationship of studies in complete BCLP and possible determinants were not synthesized due to very low quality of evidence. Clinical research for patients with BCLP should focus on sound methodological designs to enable evidence-based decision making to improve treatment for patients with BCLP and thereby hopefully their quality of life.

The oro-facial morphology is greatly affected in neonates with a cleft lip and palate. The initial evaluation of neonate's body and maxillary arch dimensions is important for treatment planning and predicting growth in cleft patients. The objective of this study was comparative evaluation of the anthropometric and physiologic parameters of cleft and non-cleft neonates in a hospital-based set up. This cross sectional study was conducted on 88 cleft and non-cleft neonates (n = 44 in each group) aged between 0 and 30 days after obtaining approval from the institutional ethics committee and positive written informed consent from their parents. Neonates' body weight, body length, head length, head circumference, and maxillary arch dimensions were measured. Maxillary arch dimensions were measured on dental casts with digital sliding calipers. Statistical analyses performed using the independent t-test and one-way ANOVA analysis were followed by Bonferroni correction for post-hoc comparison. The results showed statistically significant differences in birth weight (p < 0.0001), head length (p < 0.01), head circumference (p < 0.007), and maxillary arch dimensions (p < 0.0001) between cleft and non-cleft neonates. These findings suggest that cleft neonates had significant anthropometric and physiologic variations than non-cleft neonates.
RESUMEN
Objective: To compare cephalometric parameters in parents of children with bilateral cleft lip and palate (BCLP) and parents of children without any craniofacial anomaly. Methods: A sample of 100 sets of parents were segregated into two groups of 50 parents each. The two groups included parents of children with BCLP and the parents of children with no craniofacial anomaly. Lateral cephalograms and postero-anterior (PA) cephalograms were examined for 100 parents of both the BCLP and control group, respectively. Tracings were scrutinized for 34 linear and angular parameters of dentocraniofacial skeleton. Data were analysed using unpaired Student's t-test. Result: Evaluated lateral cephalograms revealed 15 significant parameters in parents of children with BCLP including a significant increase in Ptm-S, maxillary length, SNA, articular angle and gonial angle. A significant decrease was noted in SN length, cranial base flexion, mandibular length, mandibular body length, total facial height, upper facial height, posterior facial height, Y-axis length and soft tissue total anterior facial height. Upon evaluation of PA cephalograms, four significant parameters were found in parents of children with BCLP. Cranial width, bizygomatic width, maxillary width and lateral interorbital width were significantly decreased in the parents of children with BCLP. Conclusion: Distinct dentocraniofacial morphological features have been found in parents of children with BCLP. Evaluation of these features might be the key to predicting the occurrence of clefts in their children and also planning for future linkage analysis studies amongst them.

OBJECTIVE: In the treatment of bilateral cleft lip and palate (BCLP) patients, there is discussion about the management of the position of the premaxilla. This literature analysis summarises the literature on managing this condition. MATERIALS AND METHODS: A PubMed, Embase and Cochrane Library search was conducted resulting in 4465 articles which were screened on title and abstract. RESULTS: Seventy-one articles were available in full text, 16 of which were included in this literature analysis. We searched on keywords timing and technique, complications, growth of the maxilla and results after bone grafting the alveolar process. This literature analysis has shown that there are various ways to correct the position of the premaxilla. These can be divided into primary, early, late secondary and tertiary intervention before the age of 8 years, between the ages of 8 and 12 years and older than 12 years. Correction is done with surgery, orthodontics or a combination, with or without bone grafting. CONCLUSIONS: An osteotomy of the premaxilla in combination with secondary alveolar bone grafting appears to be the most successful technique. Combining early secondary alveolar bone grafting with osteotomy creates more room to ensure a watertight closure of the nasal mucosa resulting in fewer postoperative complications. Before surgery, the orthodontist should try to optimise the position of the premaxilla for its surgical correction prior to bone grafting. CLINICAL RELEVANCE: The treatment of BCLP patients is still based on experience and expert opinions. This literature analysis tries to give a summery on how to handle the protruded and displaced premaxilla.

This is a case report about the successful orthodontic treatment of a bilateral cleft lip and palate patient by using a combination of bone grafting and subsequent prosthodontic rehabilitation. An adult patient with a bilateral cleft lip and palate presented with a concave profile, anterior and lateral crossbite, a markedly deep overbite, and residual bilateral alveolar clefts. His jaw movement patterns were unstable and irregular due to his collapsed bite. Orthodontic treatment with bilateral bone grafting improved his concave profile by downward and backward rotation of the mandible within the freeway space, and optimum occlusion and functionally stable and smooth jaw movements were obtained. After a 6-year retention period, no skeletal relapse could be detected, and his occlusal stability was satisfactory.
