Unilateral posterior crossbite is a common form of posterior crossbite that is usually associated with a functional mandibular shift which might, in the long run, lead to mandibular asymmetry. Thus, there was a need to study this malocclusion and its influence on the facial symmetry in young adults as any factor contributing to alteration in facial symmetry requires evaluation. The purpose of the study was to assess the condylar symmetry in patients with unilateral posterior crossbite. Materials and Methodology: The study was conducted on the pretreatment orthopantomograms (OPGs) of sixty cases, out of which thirty had unilateral posterior crossbite (crossbite group) and thirty had normal occlusion in the transverse plane (control group). The Condylar height(CH), Ramal height(RH), and Condylar + Ramal height(CH+RH) were compared within the groups, and their asymmetry indices were compared between the groups using ANOVA test. Results: The CH and CH + RH were significantly reduced on the crossbite side as compared to the normal side in the unilateral posterior crossbite group. The asymmetry indices were increased in the unilateral posterior crossbite group as compared to the control group. Discussion: OPGs can be used to evaluate vertical mandibular asymmetry. The condylar asymmetry index was increased in the group with unilateral posterior crossbite indicating a greater asymmetry between the two condyles in that group as compared to the control group. The finding was in concordance with a study done in the past. Conclusion: The unilateral posterior crossbite group showed reduced CH and CH + RH values on the crossbite side in comparison to the noncrossbite side. The same group showed a greater CH index (more than 3%) as compared to the control group, indicating that the patients with unilateral crossbite develop asymmetry in the mandibular condyle region.","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":"43971567","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}

It is a known fact that lateral cephalograms are commonly used for the measurement of gonial angle, but panoramic radiographs (PRs) can display both the gonial angles simultaneously and as accurately as lateral cephalograms. The aim of this study is to develop an equation for the prediction of the skeletal pattern of nongrowing participants from gonial angle values on PR. Materials and Methods: PRs and lateral cephalograms of 75 orthodontic patients were selected. The gonial angle was measured on PR and Sella Nasion‑mandibular plane (SN‑MP) angle was measured on lateral cephalograms. The values obtained were analyzed using paired Pearson’s correlation test and regression analysis was done. Results: The relationship between the gonial angle measurements obtained from each radiograph was represented as, “SN‑MP angle (Skeletal pattern) = − 44.297 + 0.6318 × Gonial angle (PR) in the linear function.” Conclusion: Hence, PR could be used to determine the gonial angle as accurately as a lateral cephalogram and a useful tool for examining the skeletal pattern of patients.","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":"70753501","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}

Methodology: Sixty participants (20 each of laypersons, dentists, and orthodontists) were chosen for the study. Their facial photos were taken along with professional models' with normal occlusion. Participants were asked to rate self and model photos using the Visual Analog Scale (VAS) based on attractiveness; select most attractive face by looking at panels with 0°, 30°, 45°, 60°, and 90° rotated facial photos of neutral and smiling for models and self; select most attractive photo from the combination panels of neutral and smiling photos of self and model. Results: VAS scores by orthodontists for both neutral and smiling faces for both self and model were more or less similar. Dentists and laypersons found smiling photographs more attractive. The 45 angle was perceived most attractive in self and model for both the neutral and smiling categories separately by all three groups. In the combination category, orthodontist perceived the 0° smiling (model) as the most attractive followed by 45° smiling, whereas dentists and laypersons found 45° smiling photographs most attractive. Conclusion: The 45° profile view was most preferred by all three groups when assessing self as well as models. Smiling photographs of both self and model are considered more attractive than neutral photographs.","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":"44623402","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}

The most cited dental transverse discrepancies are the crossbite and scissor bite. Scissor bite is one of the toughest malocclusion to correct, and the appliances available for the effective correction are limited. one of the cause for scissor bite can be the expanded maxillary arch. The current manuscript demonstrates the effective correction of the expanded maxillary arch using the new TAS appliance. TAS appliance is an acronym for the authors (T-Tarulatha, A-Akashdeep, and S-Shyagali). The appliance construction is based on the sound biomechanical principles as well. The force was applied from the lingual side, and the applied force was nearer to the center of resistance of all the posterior teeth. Thus, the appliance produced less tipping of the molars. Unlike earlier mechanics used for the correction of scissor bite, the current appliance is not dependent on patient compliance, does not require archwire modification or the invasive procedure such as placement of mini implants or surgical intervention. The novel design of TAS appliance can help the clinician to correct the stubborn transverse discrepancy in an effective manner.","PeriodicalId":29888,"journal":{"name":"International Journal of Orthodontic Rehabilitation","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44543926","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}
