At present, more adult patients seek orthodontic treatment so orthodontists are more likely to face periodontal patients and esthetic appliance demand increases. This case report presents the management of an adult patient with mild periodontitis and severe crowding using lingual appliances and mini-screw anchorage. Interproximal stripping was performed to create space and correct the triangular tooth shape and gingival black triangles. Four mini-screws were implanted in the palatal alveolar bone and mandibular buccal shelf to distalize the entire upper and lower arch. According to the case report, interproximal stripping in combination with mini-screw-assisted entire arch distalization and lingual appliances may be an effective space-creation approach in patients treated with non-extraction way.

This study aimed to analyze and compare the temporomandibular joint (TMJ) and skeletal changes three dimensionally in growing patients with Class II malocclusion treated with the Twin block (TB) and Advansync appliance. This prospective study included 20 patients with Class II Division 1 malocclusion of which ten patients comprised the TB group and ten patients the Advansync group. Cone-beam computed tomographs were taken before treatment, and at the end of the functional phase (6–8 months). The condyle, glenoid fossa, and skeletal changes were assessed in all the three planes and the measurements were made using CARESTREAM software. The TB group demonstrated a significant increase in the condylar dimensions, superior joint space, mandibular length (P = 0.005), and decrease in anterior joint space (P = 0.001) in response to treatment and the Advansync group showed a significant increase in the condylar dimensions, mandibular length, and a significant restriction in the maxillary length. Comparison between the two groups showed a significant increase in the fossa depth in the TB group and restriction in the maxillary growth in the Advansync group. TB and Advansync group showed TMJ and skeletal changes. However, the Advansync showed more headgear effect but less glenoid fossa changes compared to the TB group.

At present, orthodontists are treating more adult patients with missing or hopeless first molars as these teeth have the highest incidence of decay in permanent dentition. This case report presented the closure of extraction spaces of four first molars in a patient with Class II malocclusion. High torque self-ligating brackets were used combined with anterior bite turbo and Class II elastics. According to the case report, the combination of anterior bite turbo and Class II elastics may have the possibility to correct bite deepening during space closure and allow further upper incisor retraction and Class II correction.

The hard and soft tissues of the head and neck, dentition, and temporomandibular joint are the determining elements in orthognathic surgery planning. The accuracy and precision of the relationship between the jaws at the beginning of treatment and their final position depend on an accurate dentition record. The aim of this study was to determine the simplest and most feasible virtual dental model transfer method for three-dimensional orthognathic planning according to clinical applicability, technical difficulty, effective costs, accuracy, and precision. A total of ten spherical porcelain markers were placed in plaster models of the maxilla and mandible of a patient. The models were scanned using an intraoral optical scanner, an extraoral digital model scanner, and cone-beam computerized tomography. To evaluate reliability, each measurement was repeated 10 times at 1-week intervals and the distances between points were measured horizontally and vertically. The findings obtained in the study were evaluated statistically using IBM SPSS Statistics 2.2 program. Measurements obtained with the extraoral model scanner did not differ from the digital caliper method (P > 0.05), while there were significant differences between the digital caliper and the other methods (intraoral 3D scanner P = 0.000; CBCT P = 0.001). Although all of the measurements showed high consistency among all methods, the most accurate results were obtained with the extraoral digital model scanner. (r = 0.99, P = 0.01, P < 0.05).
头颈部、牙列和颞下颌关节的软硬组织是正颌手术计划的决定因素。治疗开始时颌骨与最终位置之间关系的准确性和精确性取决于准确的牙列记录。本研究的目的是根据临床适用性、技术难度、有效成本、准确性和精密度，确定最简单可行的三维正颌规划虚拟牙模型转移方法。在患者的上下颌骨石膏模型中放置了10个球形瓷标记。使用口内光学扫描仪、口外数字模型扫描仪和锥束计算机断层扫描对模型进行扫描。为了评估可靠性，每个测量每隔一周重复10次，并测量点之间的距离水平和垂直。使用IBM SPSS Statistics 2.2程序对研究结果进行统计评估。口腔外模型扫描仪与数字卡尺法测量结果无显著差异(P > 0.05)，而数字卡尺法与其他方法之间存在显著差异(口腔内三维扫描仪P = 0.000;CBCT p = 0.001)。虽然所有的测量结果在所有方法中显示出高度的一致性，但口腔外数字模型扫描仪获得的结果最准确。(r = 0.99, P = 0.01, P < 0.05)。

Growth evaluation methods have made great strides in the shift from radiologic to non-radiologic biomarkers. Osteocalcin (OC), a bone protein, has been reportedly used as a biomarker for osteoblastic bone formation. The present study aimed at evaluation of serum OC in Class II skeletal patterns for accurate assessment of pubertal growth spurt to facilitate functional jaw orthopedics during the growth period. Eighty subjects, comprising 38 males and 42 females with skeletal Class II malocclusion in the age range of 11–18 years, were recruited for the study. Human serum OC was quantitatively assessed with enzyme-linked immunosorbent assay. The cervical vertebral stages were assessed from lateral cephalograms. Statistical analysis for gender-wise comparison of mean serum levels of OC at each cervical stage (CS) and in the intervals of the CSs was carried out using Kruskal–Wallis test and for intergroup comparisons, Mann–Whitney U-test with Bonferroni’s correction was done. Gender-wise comparison of mean serum OC levels revealed that it was highest in CS2 in both males (72.24 ng/mL) and females (74.71 ng/mL) with another discernible peak in CS5 in males (66.82 ng/mL) and in CS6 in females (63.78 ng/mL), exhibiting thereby a circadian rhythm in bone modeling during the entire adolescent growth spurt. Despite a pre-pubertal and a late pubertal spike in both the genders, the mean OC serum levels actually exhibited a circadian rhythmicity across all the CSs, exhorting thereby the importance of bone remodeling during the complete circumpubertal growth period.

An interrelation between the level of difficulty of canine impaction based on its three-dimensional position and the degree of root resorption of the adjacent teeth improves the quality of orthodontic treatment planning. It would be advantageous for clinicians to know the predilection of resorption in varying canine positions. The aim of the study is to evaluate and correlate the severity of root resorption of adjacent teeth and the level of difficulty of impacted canine classified by KPG Index and sector analysis using cone-beam computed tomography. The study sample comprised 48 impacted canines in orthodontic patients (17 boys and 27 girls) with a mean age of 24 years. The cone-beam computed tomographs were evaluated using Dolphin Imaging Software and primarily, three observations were recorded: KPG index, sector analysis, and root resorption. The samples were equally divided into four groups based on the KPG index, with 12 samples in each group. Additionally, the inclination of the canine in the frontal plane and their degree of vertical eruption were recorded. The number and severity of resorptive lesions increased as the KPG score escalated. The mean KPG score was 13.67 ± 6.336 and the average KPG index was 2.5 ± 1.13. A statistically significant positive correlation was found between all the parameters and root resorption. A positive correlation exists between the level of difficulty of canine impaction and root resorption of the adjacent teeth. A KPG score higher than 13.67 can be a resourceful predictor of resorptive lesions. An increased tendency of root resorption of the neighboring teeth was observed when angle α and angle β exceed 43.71° and 43.26°, respectively.

The present study aimed to analyze the outcomes of Furlow double-opposing Z-plasty techniques and to know the effect of this technique on arch dimensions and also to compare these outcomes with the ordinary technique (pushback technique) and with the control group. There are two treatment groups and one control group. Forty-two (20 males and 22 females) patients as a total number of the sample with unilateral cleft lip and palate (UCLP) children were included in this study, 1st group (10 males and 14 females) those treated with Furlow double-opposing Z-plasty performed at the age of 10 weeks repair of the lip, at 10 months closure of soft palate followed by construction of obturator done by an orthodontist, at 6 years of patient`s age a closure of hard palate, 2nd group (10 males and 8 females) treated with pushback technique. Criteria for selecting patients (two treatment groups), those without systemic diseases, cerebral disabilities, or any syndromes. The 3rd group consists of 20 healthy children (10 males and 10 females) those free from systemic diseases, aged 9–10 years old, free from oral habits and with limited or no crowding of teeth. Impressions of the upper arch of the patients were taken and the study model was poured at ages 9–10 years. Measurements include anterior arch width (ARW) or intercanine distance, posterior arch width (PAW) or intermolar distance, and arch depth (Adp). Statistical analysis; after collecting the data SPSS software program (version no. 21 Chicago, Illinois, USA) used for analysis, P ≤ 0.05 will be considered as statistically significant. The data were analyzed for their normal distribution, and a comparison of dental arch dimensions between genders and between the two techniques of surgical repair was tested by independent t-test of samples. Significant larger mean values for arch measurements ARW and Adp for males and Adp for females than with the pushback technique. This is related to the growth pattern that occurred without surgical intervention. An improvement in surgical outcomes, and the patients with UCLP treated with Z-plasty technique, revealed an increase in the mean values of arch measurements (anterior and PAW and Adp) for both genders when compared to the pushback technique, but less than that of healthy non-cleft children.

Klippel-Trenaunay syndrome (KTS) is a congenital disorder characterized by a clinical triad of capillary malformation; varicose veins; and soft tissue and/or bony hypertrophy. This rare syndrome has an estimated incidence of about 2–5/100,000 live births. KTS usually affects the extremities but occasionally can manifest in the craniofacial region, including the oral cavity. Our patient, a 17-year-old girl, presented with large areas of port wine stain, unilateral hypertrophy of the facial region, and varicose veins. She was diagnosed with KTS. Orthodontic treatment followed by orthognathic surgery was performed to address her complaint of facial asymmetry and poor chewing efficacy. Treatment resulted in significant improvement in her appearance and dental occlusion and our patient was very satisfied with the results. This report illustrates an orthodontic and surgical treatment approach of a case with KTS. Effective management of orthodontic and facial manifestations of KTS considerably enhances the patient’s function, appearance, and overall quality of life.

Over the last two decades, clear aligners have become a mainstay in contemporary orthodontic practice primarily due to improvements in digital and 3D printing technologies, a growing interest in esthetic orthodontics, especially in the adult population, and aggressive manufacturer marketing internationally. PubMed, Google Scholar, Cochrane Library, and EMBASE databases were searched from January 1998 to November 2021. The search terms used were “Invisalign” OR “clear aligner.” A total of 7000 records were searched, of which 369 potentially relevant articles were retrieved in full. 190 studies met the selection criteria following screening and were included in the scoping review. This review scopes and analyses published orthodontic literature about CA according to a year-wise distribution into 3 groups, 2001–2010/2011–2020/2021. Most of the studies were published in the period between 2011 and 2020, with 138 studies accounting for 73%. The year 2021 followed, with 31 studies accounting for 16%, which was greater than the number of studies published in 10 years from 2001 to 2010. Studies were also classified based on the study designs with most of the published studies representing the lowest level of evidence including case reports, case series, narrative reviews, expert opinions, and editorials accounting for 137 studies, whereas case-control studies were the least reported studies with only 4 studies reported in the literature. In addition, they were categorized into seven main domains: (1) Biological considerations associated with clear aligner therapy (CAT), (2) Treatment outcomes considerations associated with CAT, (3) Geometrical considerations associated with CAT (clinical), (4) Biomechanical considerations associated with CAT (Laboratory/Finite element analysis), (5) Biomaterial considerations associated with CAT, (6) Patient education and experience and aesthetic and social perception of CAT, and (7) Miscellaneous. Treatment outcome considerations associated with CAT had the greatest percentage representing 36% of the total published domains, while the final place was occupied by the biomechanical considerations associated with CAT accounting for only 4% of the published domains about CAT. Treatment outcome was the domain most commonly reported by studies accounting for (36%). Most of the published studies are at the lowest level of evidence including case reports, case series, narrative reviews, and expert opinions. The vast majority of studies utilized only a single clear aligner brand. There is a greater need for research that studies CAT from a holistic perspective.

The objective of this study was to analyze the divine proportion of lips position related to the overall face. Normative proportions were sketched in seven patterns of face on milimeter graph paper, where specific anatomical points were determined. No subjects participated in the study. The facial length was segmented into the golden ratio at point Phi (Divine proportion). Specific distances within the minor inferior subsection of the face, involving the lower and upper lips, were studied. The one-sample t-test was used to compare the means to the normative constant. The distance from Phi to the lower lip was 52% of the minor inferior facial section. The means of quotients relating lower and upper lips with point Phi were not statistically different to constant 1.618. The lower lip stands in the midpoint of the minor inferior facial section and the divine proportion was found in the position of lips within the overall face. In a time when much importance is given to lips condition, it is suitable to the orthodontist and general dentists to recognize its natural positions on a regular basis.
