Abstract Objective: To test the null hypothesis that the spheno-occipital synchondrosis does not show bony displacement in response to rapid maxillary expansion (RME) therapy in youngsters. Materials and Methods: A total of 16 computed tomography (CT) records were taken from 8 growing patients (2 males and 6 females), before (T0) and after (T1) treatment with RME. All patients had been diagnosed originally with transverse maxillary deficiency. The mean chronological age of the patients was 9.8 ± 1.8 years (range, 8 to 11.4 years). High-resolution multislice multidetector CT was used to study quantitatively the extent of the opening of the spheno-occipital synchondrosis following RME. A low-dose CT scan protocol was used (80 kV, 10 mA) and the data file of each patient was transferred to a workstation where the anteroposterior width of the spheno-occipital synchondrosis was measured on axial images. Results: Before treatment with RME (T0), the anteroposterior mean width of the spheno-occipital synchondrosis was 1.73 ± 0.46 mm immediately after the active phase of expansion (T1), and the width of the synchondrosis increased to 2.30 ± 0.47. This difference was statistically significant according to the Wilcoxon signed rank test (P < .05). Conclusion: Rapid maxillary expansion leads to a small immediate widening of the spheno-occipital synchondrosis in youngsters.

ABSTRACT Objective: To evaluate the effects of modified bonded rapid maxillary expansion (RME) on occlusal force distribution. Materials and Methods: The sample included 12 patients (7 girls and 5 boys; mean age: 13.1 years) at the permanent dentition stage with bilateral posterior cross-bite. The patients were treated with a modified bonded RME appliance, activated twice a day. The study was terminated when the palatal cusps of the maxillary posterior teeth were occluding with the buccal cusps of the mandibular posterior teeth. The postretention period was 3 months. The T-Scan III device was used to analyze the percentages of occlusal force distribution, and records were taken at the pretreatment (T1), the postreatment (T2), and the postretention (T3) periods. Wilcoxon signed rank test was used for statistical analyses. Results: Incisors were most frequently without contact, followed by canines. The highest forces were seen in the second and first molar regions. A significant decrease was seen in total occlusal force during treatment (T1–T2); however, during retention, the force returned to its initial value, and no significant differences were found (T1–T3). No differences were found between right and left sides and in occlusal forces of the teeth in all time periods. Conclusion: The use of modified bonded RME decreases the total occlusal forces during the treatment period, but it does returns to its initial value after the postretention period.

Abstract Objectives To evaluate the precision of aligner (Invisalign®) treatment with the current material (SmartTrack®) in achieving expansion or contraction of the maxilla and occlusal contacts as simulated in the proprietary planning software (ClinCheck®, CC). Materials and methods Thirty patients thus treated were retrospectively evaluated. Four maxillary models were analyzed per patient: a pretreatment model, a scan-based CC model, a posttreatment clinical model, and a CC model reflecting the treatment outcome as initially simulated. Thirteen transverse parameters were measured on each model separately by two investigators. Occlusal contacts were also analyzed. Results The measuring method was validated by both investigators arriving at similar results for the effectiveness by which the simulated treatment goals had been clinically achieved. Significant differences (p < 0.05; Wilcoxon signed-rank test) were observed for transfer precision from the casts to the planning software and between the simulated and clinical outcomes. Intense occlusal contacts in the simulations materialized less common (≈ 2%) than ideal contacts (≈ 60%) in the clinical outcomes. Conclusions The effectiveness of achieving the simulated transverse goals was 45% and was generally not found to be better with SmartTrack® than with the previously used Ex30® material. Out of 100 simulated occlusal contacts, 40 will never materialize, and achieving around 60 will adequately ensure a clinically favorable contact pattern. Clinical relevance With the caveat that any overcorrection will to some extent reduce the precision, it seems perfectly possible to make deliberate use of overcorrection in current aligner therapies for transverse maxillary expansion or contraction.

Introduction: Pharmacological and non-pharmacological techniques are methods used to reduce labor pain. Non-pharmacological techniques in the form of distraction by listening to the murottal Al-Qur'an can be an option. The purpose of this study was to determine the effect of murottal Al-Qur'an therapy on reducing the intensity of labor pain during the 1st active phase. Method: The type of research used in this study was Pre Experiment, one group pretest-posttest research design. The population in this study were mothers who gave birth at the first stage of Sriwati PMB with a sample of 15 people. The pain was measured using the Numeric Rating Scale (NRS). Statistical analysis used the Wilcoxon Signed Rank Test with a confidence level of 95% (α = 0.05). The result of the statistical test, the value of p=0.001, which means that there is a significant difference in labor pain in women who give birth before and after listening to the Murottal Al-Qur'an. It is suggested to do non-pharmacological techniques to listen to Murottal Al-Qur'an as one of the techniques to reduce the first stage labor pain at PMB Sriwati.

ABSTRACT Objective:  To evaluate transverse dimensional changes in dentoalveolar and skeletal structures caused by hybrid expander, using cone-beam computed tomography (CBCT). Materials and Methods:  The CBCT records of nine patients (five boys and four girls) (mean age 13.61 ± 0.72 years) treated with hybrid expander were examined. CBCT images were taken at pretreatment and after the expansion. ELSA (point equidistant to both foramina spinosa) was determined as a reference point to compare the distances in all three dimensions. Nineteen transversal dimensions and four angles were measured for both right and left sides. Wilcoxon signed rank test was used for statistical comparison at P &lt; .05 levels. Results:  A V-shaped expansion of suture was successfully achieved in all patients without teeth support. The amount of opening was greater in anterior than posterior and in inferior than superior. An 8.75-mm screw expansion was achieved for all patients. Expansion effects reverberated to maxillary central incisor, canine, first premolar, and first molar at 70%, 75%, 92%, and 89%, respectively. The molar teeth tipped buccally (right 3.06° and left 3.24°) as did premolars (right 2.88° and left 3.02°). Conclusion:  The hybrid expander, minimally invasive expansion appliance that protects teeth by including bone support, can be used easily for rapid maxillary expansion treatment.

ABSTRACT Objective:  To evaluate the stability of nonsurgical miniscrew-assisted rapid maxillary expansion (MARME) in young adults with a transverse maxillary deficiency. Materials and Methods:  From a total of 69 adult patients who underwent MARME followed by orthodontic treatment with a straight-wire appliance, 20 patients (mean age, 20.9 ± 2.9 years) with follow-up records (mean, 30.2 ± 13.2 months) after debonding were selected. Posteroanterior cephalometric records and dental casts were obtained at the initial examination (T0), immediately after MARME removal (T1), immediately after debonding (T2), and at posttreatment follow-up (T3). Results:  Suture separation was observed in 86.96% of subjects (60/69). An increase in the maxillary width (J-J; 1.92 mm) accounted for 43.34% of the total expansion with regard to the intermolar width (IMW) increase (4.43 mm; P &lt; .001) at T2. The amounts of J-J and IMW posttreatment changes were −0.07 mm (P &gt; .05) and −0.42 mm (P  =  .01), respectively, during retention. The postexpansion change in middle alveolus width increased with age (P &lt; .05). The postexpansion change of interpremolar width (IPMW) was positively correlated with the amount of IPMW expansion (P &lt; .05) but not with IMW. The changes of the clinical crown heights in the maxillary canines, first premolars, and first molars were not significant at each time point. Conclusions:  Nonsurgical MARME can be a clinically acceptable and stable treatment modality for young adults with a transverse maxillary deficiency.
