Background: The aim was to use an alternative technique to orthognathic surgery with similar functional and aesthetic outcome with the added advantages of being less invasive and comfortable to a patient. Here, we evaluate the efficacy of PRP in the acceleration of Orthodontic treatment using Invisalign to correct a malocclusion of Class III with functional reverse bite in a patient who declined surgery but requested the least visible and time consuming procedure. Methods: PRP was applied three times during the course of the therapy. The orthodontic treatment lasted 10 months. The patient was further provided with restorative care. Protrusion of teeth 11, 21, and 22 by bodily movement, shaping of the upper dental arch and rectification of lower incisors were achieved with no adverse effect to the patient’s dental health. Since we assumed that the pathophysiology of the effect of PRP is the same as for corticotomy, we must assume an effect lasting only three months. The great advantage of our method is the fact that it is a minimally invasive technique and hence we could repeat the procedure thrice. Results: Three applications of PRP significantly shortened the length of orthodontic therapy from 21 months to 10 months. Conclusions: We can conclude that although the technique is perhaps a bit lengthy in terms of time taken to achieve the desired results after surgery but it provides a safe alternative approach for patients who decline surgery or instances where surgery cannot be carried out.

Crossbite is one of the most prevalent malocclusion, posterior crossbite occurs in 8% to 22% of orthodontic cases and anterior crossbite has been seen in Class III cases, which accounts for 3.4% of orthodontic cases. The etiology of posterior crossbite can include any combination of dental, skeletal, and neuro muscular functional components, but the most frequent cause is reduction in width of the maxillary dental arch. Patients/cases seeking comprehensive orthodontic treatment in between 5 to 35 years were diagnosed for crossbite with diagnostic model and care record file. Out of 300 cases 163(54.3%) had crossbite, 90(30%) had anterior crossbite and 109(36.3%) had posterior cross bite. Among posterior crossbite 60(20%) had unilateral and 49(16.3%) had bilateral crossbite. Posterior crossbite was more prevalent than anterior crossbite. Cases with Class I molar relation showed more crossbite. Crossbite was more prevalent in cases with congenitally missing teeth.Bangladesh J Medicine Jan 2015; 26 (1) : 9-12

Craniofacial Features

Basal cell nevus syndrome (BCNS) is a rare genetic disorder that can be caused by mutation of multiple genes, including PTCH1, PTCH2, and SUFU, in an autosomal dominant manner. The symptoms include some craniofacial features such as keratocystic odontogenic tumors (KCOTs), macrocephaly, and cleft lip and/or palate. Although comprehensive orthodontic treatment is frequently required for some of these craniofacial deformities, there are few reports that show the outcomes of comprehensive orthodontic treatment. Here, we report a case of BCNS with multiple KCOTs, macrocephaly, skeletal class III malocclusion, asymmetric dental arch, and mandibular crowding, which was successfully treated with comprehensive orthodontic treatment.

ABSTRACT Objective: To examine the current trends in surgical-orthodontic treatment for patients with Class III malocclusion using time-series analysis. Materials and Methods: The records of 2994 consecutive patients who underwent orthognathic surgery from January 1, 2004, through December 31, 2015, at Seoul National University Dental Hospital, Seoul, Korea, were reviewed. Clinical data from each surgical and orthodontic treatment record included patient's sex, age at the time of surgery, malocclusion classification, type of orthognathic surgical procedure, place where the orthodontic treatment was performed, orthodontic treatment modality, and time elapsed for pre- and postoperative orthodontic treatment. Results: Out of the orthognathic surgery patients, 86% had Class III malocclusion. Among them, two-jaw surgeries have become by far the most common orthognathic surgical treatment these days. The age at the time of surgery and the number of new patients had seasonal variations, which demonstrated opposing patterns. There was neither positive nor negative correlation between pre- and postoperative orthodontic treatment time. Elapsed orthodontic treatment time for both before and after Class III orthognathic surgeries has been decreasing over the years. Conclusion: Results of the time series analysis might provide clinicians with some insights into current surgical and orthodontic management.

Summary Introduction. Although severe root resorption is rare, it is a side effect of orthodontic treatment which affects tooth prognosis. Patients with severe dentofacial deformity, for whom orthodontic treatment and orthognathic surgery was done at the age of 18 and later, had long duration orthodontic treatment and orthognathic surgery, and are at a high risk of root resorption. The impact of orthognathic surgery on root resorption has not been sufficiently studied, and therefore is an interesting topic to research. Aim of the Study. To identify the risk factors for apical root resorption of maxillary incisors and canines as a result of orthodontic and surgical treatment of Class III malocclusion involving LeFort I osteotomy. Material and methods. The root lengths of upper incisors and canines were measured on cone beam computer tomography (CBCT) scans obtained from a database of orthognathic surgery patients. As a criteria for root resorption was chosen the difference in root lengths between different time points. The measurements were performed using the scans taken before orthodontic treatment (T1), before surgery (T2), and after post surgery orthodontic treatment (T3), of 28 subjects, aged 20.5 ± 3.81 years, with the mean presurgery treatment time of 19.9 ± 8.8 months, and post-surgery time of 7.1 ± 3.1 months. Changes in root lengths during different time spans were correlated with treatment duration, the initial crown/root ratio, and the severity of dentofacial deformity (Wits appraisal, ANB angle, and overjet). Results. During T1 - T2 the roots of the lateral incisors shortened by a maximum of 0.78 ± 0.83 mm (p < 0.001), at a rate of 0.04 mm per month. During T2 - T3 the lengths of the central incisor roots decreased most by 0.49 ± 0.52 (p < 0.001) at a rate of 0.07 mm per month. The resorption speed for canines increased from 0.03 mm to 0.1 mm per month before and after surgery. There were statistically significant correlations between the crown-root ratio and the incisor root length (r = 0.319 for lateral and r = 303 for central, both p<0,05) and for canines (r = 482, p<0.01). The associations between the shortened root length, in different time spans for different teeth, and the severity of malocclusion were inconsistent. Conclusions. Overall, the shortened root length during combined orthodontic and surgical treatment might not be clinically significant. After surgery, the rate of root resorption (mm per month) increased, especially for canines. The teeth with initially shorter roots showed more resorption during treatment.

Objective. The aim of this study was to evaluate the need for orthodontic treatment among 12-year-old school children and 18-year-olds from Da Nang, Vietnam.Basic Research Design. A random representative sample of 200 12-year-old children from primary schools in Da Nang city was gathered. In addition, 200 18-year-old students were randomly selected from among the 4000 students studying at Da Nang University of Medical Technology and Pharmacy, Vietnam. All the subjects were evaluated according to Angle’s molar relationship, the presence of malocclusion, and the components of the Index of Orthodontic Treatment Need (Dental Health Component, DHC, and Aesthetic Component, AC).Results. The DHC of index of orthodontic treatment need (IOTN) for 12-year-olds was in 60% of casesno or little, in 21% of casesmoderate, and in 19% of casesdefinitive, while the prevalence of moderate and definitive need for treatment among the 18-year-olds was 24% and 30.5%, respectively. The prevalence of class III malocclusion, contact point displacement, and crossbite was higher in 18-year-olds than among the 12-year-olds, while the prevalence of increased overjet and increased overbite had decreased in 18-year-olds compared to the group of 12-year-olds.Conclusions. There is a strong need for orthodontic treatment in Vietnam’s population. The need for orthodontic treatment was determined by contact point displacement, crossbite, increased overjet, and increased overbite.

INTRODUCTION: This case report describes the orthodontic treatment of an adult patient with skeletal Class III malocclusion and anterior crossbite. A short cranial base led to difficulties in establishing a cephalometric diagnosis. The patient's main complaint comprised esthetics of his smile and difficulties in mastication. METHODS: The patient did not have the maxillary first premolars and refused orthognathic surgery. Therefore, the treatment chosen was orthodontic camouflage and extraction of mandibular first premolars. For maxillary retraction, the vertical dimension was temporarily increased to avoid obstacles to orthodontic movement. RESULTS: At the end of the treatment, ideal overjet and overbite were achieved. CONCLUSION: Examination eight years after orthodontic treatment revealed adequate clinical stability. This case report was submitted to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO) as part of the requirements to become a BBO diplomate.
