ABSTRACTBackground Conventional Two Flap Palatoplasty technique will made lateral defects without any periosteal coverage. These denuded lateral defects are prone to contamination and infection. These will result in wound contraction, scar formation and maxillary growth impairment.In 2011, we studied ldquo The Non Denuded Palatoplasty rdquo technique. This technique precipitated the epithelialization process of the lateral defects. Faster epithelialization is expected to decrease wound contraction and in the long run will result in good maxillary growth.Methods This is a case control study to compare the maxillary growth of 2 groups consists of unilateral cleft lip and palate patients repaired with ldquo The Non Denuded Palatoplasty rdquo technique and Conventional Two Flap Palatoplasty. The outcome will be evaluated from cephalometry and the dental cast for each patient areevaluated using GOSLON YARDSTICK method. Data will be analyzed using SPSS version 20.Results A total of 4 patients in The Non Denuded Palatoplasty group and 10 in the Conventional Two Flap Palatoplasty. The cephalometric SNA, SNB and ANB point showed Class III skeletal jaw relationship or deficient maxilla. While the GOSLON yardstick type III are the frequent GOSLON on both group with good inter ratter reliability p 0.839 based on Mann Whitney test. In these study there were no correlation between cephalometric variables with GOSLON score.Conclusion Our results showed that modification The Non Denuded Palatoplasty technique made no statistically significant difference to the maxillary growth. However this study has several limitations, which are the sample size was small due to family, social and other factors that are beyond the control of the investigating team. Also the age of evaluation 7 9 years , means that the result is not the final outcome. "

Background: Cleft lip and palate is a common congenital disorder that formed during fetal development due to failure of the developmental processes of the face. Three-dimensional (3D) maxillary growth deficiency is often found in patients with cleft lip and palate, particularly in unilateral cases. Patients who had undergone surgical procedures show a decrease on cranial base height, shorter maxilla, severe maxillary retrograntic and more lingual inclination of upper and lower incisor teeth. Multistage treatment is neccessary for patients with the lips and palate such as alveolar bone repair, prosthodontic restoration, and definitive dental correction. Objective: To analyze the effect of labioplasty and palatoplasty to maxillary height, maxillary sinus volume and sella turcica size in patients with unilateral cleft lip and palate. Materials and Methods: Observational analytic study with cross-sectional design. The subjects of this study were children ³13-years-old with unilateral cleft lip and palate, had undergone labioplasty and palatoplasty, and did not undergo fixed orthodontic treatment procedures at RSAB Harapan Kita, Jakarta in the period of 2011-2013. Based on the inclusion and exclusion criteria, a total of 12 subjects were obtained. Each subject took a CBCT radiographic to assess the maxillary height, maxillary sinus volume and sella turcica size. Comparison of maxillary height and maxillary sinus volume was performed on the cleft and normal sides, while the comparison of the size of the sella turcica was performed descriptively using secondary data. Results: There are significant differences in the maxilla height and maxillary sinus volume between the cleft side and the normal side (p = 0.00 and p = 0.01). There is a difference in width and height of the sella turcica between the subject and the control group. Conclusion: Labioplasty and palatoplasty affect maxillary height, maxillary sinus volume and sella turcica size in patients with unilateral cleft lip and palate."

ABSTRACT

Miniscrew-assisted upper first molar intrusion had been developed recently with high rate of success. The placement of two miniscrews, buccally and palatally, is usually done to deliver such force. This research was conducted to analyse the difference of stress distribution of upper first molar intrusion using two miniscrews, placed at 3 mm, 5 mm, and 7 mm from cementoenamel junction, and 45° and 90° from the tooth axis. A three-dimensional solid model of craniomaxillary structure was rendered and the region of interests (ROI) were defined at the first molar roots, its alveolar, miniscrews, and the bone surrounding the miniscrews. Statistical analysis showed that there were significant differences (p<.05) of Von Mises mean values in the ROIs between all groups of height and angle of placement. Visual analysis showed that the stress distribution in first molar roots were concentrated at the trifurcation and palatal root apex area, while in the bone surrounding the miniscrews, the highest stress distribution was located diversely among separate angles of placement groups. The stress distribution of upper first molar intrusion using miniscrews anchorage was affected by heights and angles of miniscrews placement.
