Therefore, it becomes crucial to quantify the soft-tissue response to changes in the hard tissue following orthodontic treatment. Purpose of the Study: To determine lip morphology changes after first premolar extractions in patients with bimaxillary protrusion as ratios of hard and soft-tissue changes. Materials and Methods: The sample consisted of pretreatment and posttreatment lateral cephalograms of 15 subjects with Class I bimaxillary protrusion who had undergone orthodontic treatment with four first premolars extraction and retraction of upper and lower incisors. Pre- and post-treatment lateral cephalograms were traced and superimposed by using SN-7˚ plane. Sixteen linear measurements were made. Statistical analysis was performed to analyze the co-relation between the hard and soft tissue change by Pearson's correlation. Stepwise multiple regression were made to determine factors that related with lip changes. Results: Significant changes after treatment were found both in dental and lip analysis. The equations of upper and lower lip changes in sagittal and vertical dimensions were derived. Conclusion: Stepwise multiple regression analysis revealed that a 1 mm retraction of the maxillary incisor cervical point would produce a 0.59 mm retraction of upper lip and 1 mm retraction of the mandibular incisor cervical point would produce 0.89 mm retraction of the lower lip. The predictability of this study may be helpful for the clinician in predicting the amount of change in profile of the patient post treatment, thus aiding in planning the treatment.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44362719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: The sample size with 80% power was 45. The samples were divided into three groups each group consisting of 15, Group 1 – Clarity Advanced Ceramic Brackets (3M Unitek). Group 2 – Metal insert Ceramic Brackets (3M Unitek). Group 3 – Conventional Metal Brackets, the control group (3M Unitek). The wires used for testing were 0.016” Niti, 0.017 ×× 0.025” Niti and 0.019 ×× 0.025” SS. Results: In the present study, it was found that wire material (nickel titanium) had an effect on friction. It was found that metal insert ceramic bracket exhibited similar frictional resistance when compared to metal brackets for 0.017 × ×0.025” Niti and 0.019 × 0.025” SS wires. The Clarity Advanced bracket had the highest frictional resistance followed by metal insert ceramic and least with the conventional metal. Conclusion: Clarity advanced can be the bracket of choice for the esthetically discerning patients who do not require extraction for orthodontic reasons, but the high frictional resistance in relation to larger rectangular Niti archwires should be considered. In adult patients who require extraction in the treatment plan, metal insert ceramic brackets are definitely a pleasing alternative when compared to metal brackets.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42409667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both the patients had a skeletal Class II malocclusion with Angle's Class I molar relation, Class I canine relation, proclination of upper and lower anterior teeth. In the first case, intrusion and retraction was done with conventional friction mechanics for space closure and an intrusive force from a mini-implant placed in the midline. In the second case, intrusion and retraction were done with the application of force from the anterior attachments to mini-implants placed between the second premolars and first permanent molar bilaterally. There was intrusion of the maxillary anterior teeth with both mechanics. However, the evaluation of treatment outcome at the end of space closure showed mesial movement of the maxillary first permanent molar in the first case. In the second case, distal movement and intrusion of the maxillary first permanent molar and decrease in the lower anterior facial height was noted. The mechanics in the first case can be applied for intrusion and retraction of maxillary anterior teeth when anchorage requirement is not critical. The mechanics described in the second case can be used for intrusion and retraction of maxillary anterior teeth in cases with a very high anchorage need and will be beneficial in patients with vertical growth pattern.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43475047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
