This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: The aim of this study was to investigate the effect of extraction and non-extraction orthodontic treatments on oral commissures.Materials & Methods: Pre- and post-treatment 3dMD images of 47 patients aged 10-19 were studied for changes in inner and outer commissure width, philtrum height and buccal corridor width. The subjects either had extractions of all four first premolars, upper first premolars only, or were treated non-extraction. The superimposed 3dMD images were collected and qualitative and quantitative analyses were completed using 3dMD Vultus software. Interincisal angle and upper incisor to NA changes were also calculated using pre- and post-treatment lateral cephalograms. Regression analyses were applied controlling for age, gender, ethnicity, angle classification, and treatment time. Results: While all groups showed a nominal increase in the inner and outer commissure widths from T0 to T1, only the non-extraction group revealed a statistically significant change (p

Book Synopsis Effect of Double Transpalatal Arch During Extraction Treatment of Class II Malocclusion by : Pushpak Patel
Download or read book Effect of Double Transpalatal Arch During Extraction Treatment of Class II Malocclusion written by Pushpak Patel and published by . This book was released on 2009 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Anchorage and vertical control are some of the limiting factors in orthodontics, and their control is essential for successful orthodontic treatment. The purpose of this retrospective cephalometric study was to quantify the anchorage and vertical control capabilities of the double TPA by comparing Class II patients treated with full fixed appliances (Roth prescription - GAC 022x028 Slot), extraction of maxillary first bicuspid and utilizing double TPAs on first and second molars to a control sample of matched untreated Class II patients. Methods: Pretreatment and post treatment lateral cephalograms were analyzed of 20 patients (10 male and 10 female) from the same orthodontic practice with skeletal Class II malocclusions, characterized by hyperdivergent growth patterns. All of the 20 patients had maxillary first premolar extractions and double TPAs on the maxillary first and second molars. Space closure was done without headgear, utilizing only double key-hole closing loop archwires. The experimental sample was matched to controls from the Michigan and Bolton Brush growth studies. 12 cephalometric variables were identified to evaluate the effect of double TPAs on various skeletal and dental parameters including anchorage and vertical control. Results: Upper first molar horizontal movement in TPA experimental group: U6-PT Vertical=0.9mm, 6-PTV UMKC=1.2mm and H Perp to mestal U6-0.6mm, moved less forward compared to controls. Upper first molar vertical movement in TPA experimental group: U6-PP measurement in the TPA group was 1.9mm less compared to controls. U6-SN measurement was statistically insignificant between the two groups. Conclusions: Double TPAs were shown to effectively hold the anchorage and control the vertical in the treatment of skeletal Class II hyperdivergent patients.

Book Synopsis THREE-DIMENSIONAL ASSESSMENT OF THE EFFECTS OF EXTRACTION ON THE SMILE IN CLASS II HIGH AND LOW MANDIBULAR PLANE ANGLE PATIENTS by : Neil E. Uffner
Download or read book THREE-DIMENSIONAL ASSESSMENT OF THE EFFECTS OF EXTRACTION ON THE SMILE IN CLASS II HIGH AND LOW MANDIBULAR PLANE ANGLE PATIENTS written by Neil E. Uffner and published by . This book was released on 2013 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The annals of orthodontics are filled with studies aimed to understand how extraction orthodontic treatment might change the face. Although many studies have addressed profile changes due to extraction treatment, fewer studies have focused on how extractions change a patients smile. With the advent of surface imaging systems such as 3dMD, it is now possible to visualize the smile, and any changes incurred during orthodontic treatment, in three dimensions. Subjects for this study were chosen from the pool of 11-18 year old patients treated at the Podray Orthodontic Clinic at the Temple University Kornberg School of Dentistry. Subjects were Cl II patients, and must have been treated with either extraction of any combination of premolars or treated without extraction. Subjects were divided into four experimental groups based on two characteristics- mandibular angle (those with angles greater than 28o versus those with angles less than 28o) and treatment (extraction versus non-extraction). The resulting groups were separated as follows: high-angle extraction patients (n=8), low-angle extraction patients (n=6), high-angle non-extraction patients (n=7), and low-angle non-extraction patients (n=15). For each subject initial and final 3dMD images were superimposed using 3dMD Vultus software. A color histogram was constructed to visualize changes during treatment. The cheeks, commissures, upper and lower lips, chin, and nose, were also landmarked, and the changes in these landmarks were calculated. Volume changes were also calculated between pre and post treatment 3D data. Results showed that the lower lip and right commissure changes between high-angle extraction and non-extraction groups were statistically significant. A qualitative analysis of the histograms further supported these findings. In general, a greater change in soft tissue landmarks and soft tissue volumes could be seen in high-angle patients than low-angle patients. Differences in the changes that result from treatment type (extraction vs. non-extraction) were seen in the high-angle group. In contrast, similar changes result from treatment type (extraction vs. non-extraction) in the low-angle groups. Furthermore, the lip changes seen in extraction patients upon smiling are very similar to those changes seen in the same patient in repose. Most interestingly, soft tissue differences of the face due to treatment, growth, or both, seem to disappear upon smiling, with the exception of the lips. Qualitative assessment of these changes in the smile might be a more appropriate method for identifying soft tissue changes than statistical analyses. Similar studies with larger sample sizes are a promising direction for future research.

Book Synopsis Premolar Extractions & Boltons Ratio in South Indian Population. by : Anshul Srivastava
Download or read book Premolar Extractions & Boltons Ratio in South Indian Population. written by Anshul Srivastava and published by LAP Lambert Academic Publishing. This book was released on 2014-09-18 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A retrospective study was conducted to investigate the effects of premolar extractions on Bolton overall ratios and tooth size discrepancies in Dakshina Kannada population. The materials used were 264 pretreatment plaster casts from Department of orthodontics of various dental colleges of Dakshina Kannada. Mesiodistal tooth widths were measured using digital vernier calipers. Bolton's ratios were determined before and after hypothetical premolar extractions in various combinations.The results of this study showed: The significantly notable decrease in overall ratios for all second premolars and maxillary second and mandibular first premolars for Dakshina Kannada population.From the results we can conclude that generally the tooth material ratio of Dakshina Kannada population shows a mild maxillary tooth material excess. In patients requiring extraction, all first premolars or maxillary first and mandibular second premolar extraction should be preferred
