Introduction Floating norms put us at ease while diagnosing and establishing a treatment plan for an individual with abnormal skeletal pattern. It uses the variability of the associations among appropriate cephalometric variables and later on the basis of a regression model by combination of both skeletal parameters which are sagittal and vertical and construct a harmony box which make diagnosis straightforward. This study aims to establish floating cephalometric norms for the describing individual craniofacial skeletal pattern among North Indian Adults as an additional diagnostic tool for orthodontic treatment planning. Materials and Methods The study includes North Indian adults in age range of 17 to 25 years. A total of 30 patients were selected and were subjected to cephalometric evaluation. Various angular measurements viz., SNB (sella-nasion-point B), NL-NSL (maxillary line-nasion sella line), ML-NSL (mandibular line-nasion sella line), N–S–Ba (nasion-sella-basion), SNA (sella-nasion-point A), and ML-NL (mandibular line-maxillary line) were considered for designing harmony box for North Indian adults. Results The results of the study were subjected to various statistical analyses. SNB served as the independent variable and NL-NSL, NSBa, ML-NSL, ML-NL, and SNA were made the dependent variable due to lesser R2 values in multiple regression analysis. Correlation between some of the variables, such as (SNA–SNB, ML-NSL–NL-NSL, and ML-NSL–ML-NL), in the present North Indian sample showed positive correlation among each other and were statistically significant (p = 0.000). When compared with the other similar studies done previously, least variability was seen with the Segner study and maximum variability was seen with Thilander’s study. Conclusion The analysis of the individual craniofacial pattern by means of floating norms appears to provide a helpful method in determining the parameters responsible for the skeletal disharmony, thus representing a viable option for additional diagnostic tool in orthodontic and orthopaedic/surgical treatment planning.
Dental anterior open bite is a condition which is characterised by decreased incisor dentoalveolar height. The occlusal planes in the dental anterior open bite usually diverge from the mesial to the first premolar forwardly. This case report describes the treatment of dental anterior open bite. A male patient aged 23 years presented 6.0 mm anterior open bite along with increased lower anterior facial height. Other features included incompetent lip, deficient incisor display during rest and smile, irregular upper and lower anteriors. Management included extrusion of both upper and lower anterior teeth with camouflage non-extraction therapy. There was no recurrence of anterior open bite, and a balanced occlusion was maintained during the follow up of next 2 years after treatment completion which suggested a long-term stability of occlusion.
Introduction The facial growth pattern differs from individual to individual, and the variations in it are quite high. The assessment of relationship of dental arch dimensions with the facial growth pattern is essential for proper diagnosis and treatment planning. Aim The purpose of this study was to evaluate and compare the dental and alveolar arch widths in patients with varying facial growth patterns in Distt. Solan population. Materials and Methods Pretreatment lateral cephalograms and dental study models of 45 patients with age group between 16 and 30 years were included in the study. Patients were divided into three groups: group I (normodivergent), group II (hypodivergent), and group III (hyperdivergent) on the basis of y-axis, Jarabak ratio, and SN-MP (Sella-Nasion–mandibular plane) angle. Interpremolar and intermolar dental and alveolar arch widths were measured and compared for all the three groups. Results The results showed that the dental and alveolar arch widths were increased in hypodivergent patients and decreased in hyperdivergent patients, which was not statistically significant. Conclusion It was concluded that the dental and alveolar arch dimensions increased as the facial pattern became horizontal.
Among the various congenital dental abnormalities in children, loss of tooth due to trauma and hypodontia are few that are most prevalent. A wide range of treatment modalities are available for these abnormalities, however, removable prosthesis is the most common treatment option to be used, but a pitfall of this method is that it may increase the residual alveolar bone resorption and other problems related to periodontal support of the remaining teeth. Dental implants, another treatment modality, are generally advocated in adults or young patients that are beyond their craniofacial growth potential. This comprehensive review will discuss the use of dental implants in normal growing patients and some special scenarios including orthodontic consideration and mini-implant use in pediatric population. This review sorted the literature in main themes of influence of growth on the usage of dental implants in children; use of dental implants in children suffering from ectodermal dysplasia; use of dental implants in traumatic dental injuries sustained in children; and for orthodontics intervention during childhood. The literature was searched using databases such as PubMed, Scopus, MEDLINE, and Google. The titles and abstracts were screened, and full text was retrieved for publications that studied the use of dental implants in children in any form of intervention. The results indicated that scientific studies have documented high functional and esthetic results in cases of prosthetic treatments on implants, min-implants in children. However, the use of implants in children is high restricted to anterior mandibular region, with most clinicians opting for growth completion before implant placements. The establishment of the mastication, speech function, and normal appearance is highly crucial for growth of the jaws and facial bones. However, isolated use of mini-implants in growing children has definitely broaden the idea of the use of implant modification in children, yet to achieve maturation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
