Background/Objectives: Orthognathic treatment is routine practice to rehabilitate severe malocclusions and dentofacial deformities. Because orthognathic treatment is elective, patient's involvement in deciding whether to proceed with treatment is vital. Interaction and communication between patient and treating team plays a key role in achieving post-treatment satisfaction. To achieve satisfaction, an orthognathic 'information clinic' for prospective orthognathic patients was established at Oral and Maxillofacial Unit, Tampere University Hospital, Finland...

Hypodontia, or tooth agenesis, is the most prevalent craniofacial malformation in humans. It may occur as part of a recognised genetic syndrome or as a nonsyndromic isolated trait. Excluding third molars, the reported prevalence of hypodontia ranges from 1.6 to 6.9%, depending on the population studied. Most affected individuals lack only one or two teeth, with permanent second premolars and upper lateral incisors the most likely to be missing. Both environmental and genetic factors are involved in the aetiology of hypodontia, with the latter playing a more significant role...

In a time when orthodontists are getting away from paper charts and going digital with their patient data and imaging, practitioners need to be prepared for a potential hardware failure in their data infrastructure. Although a backup plan in accordance with the Security Rule of the Health Insurance Portability and Accountability Act (HIPAA) of 1996 may prevent data loss in case of a disaster or hard drive failure, it does little to ensure business and practice continuity. Through the implementation of a common technique used in information technology, the redundant array of inexpensive disks, a practice may continue normal operations without interruption if a hard drive fails...

INTRODUCTION: Malocclusion plays an important role in the development of periodontitis. Thus, by treating malocclusion, a good gingival health can be achieved. This study was conducted to establish the correlation between orthodontic tooth movement and periodontitis. MATERIALS AND METHODS: This is a retrospective study conducted on 220 patients who underwent orthodontic treatment for malocclusion. They were divided into two groups: Group I patients were treated with fixed orthodontics, while group II patients received myofunctional appliances...

Background: Orthodontic diagnostic standards generally use the cranial base as a reference and rely on samples selected by orthodontists. Objective: The purpose of this study was to provide male and female standards for a novel non-radiographic approach for orthodontic diagnosis that utilizes 3D dentofacial photogrammetry using the eyes and natural head orientation as references instead of the cranial base. Methods: One hundred and eighty females and 200 males between the ages of 18 and 35 years from 2 modeling agencies were orthodontically screened for near ideal occlusion...

OBJECTIVE: Researchers have documented secular trends in tooth size among recent generations. This study was a test for a change in mandibular leeway space. MATERIALS AND METHODS: Dental casts from participants in the Denver Growth Study (23 boys, 22 girls; born in the 1930s) were compared with casts from a contemporary series of orthodontic patients (23 boys, 22 girls; born in the 1990s). All were phenotypically normal, healthy American whites. RESULTS: Analysis of variance (accounting for sex) showed that the cumulative mandibular primary canine plus first and second primary molar size (c + m1 + m2) was slightly larger in the recent cohort (23...

BACKGROUND: Age is a factor affecting smile esthetics. Three variables of smile esthetics associated with the maxillary anterior teeth and age-related changes have recently received considerable attention: (i) the incisal edge position of the maxillary central incisors, (ii) the maxillary gingival display, and (iii) the presence of a black triangle between the maxillary central incisors. The aim of this study was to evaluate the influence of age on smile esthetic perception based on these three variables in a group of Thai laypeople...

REVIEW
Rajesh Gyawali, Bhagabat Bhattarai
Aggressive periodontitis is a type of periodontitis with early onset and rapid progression and mostly affecting young adults who occupy a large percentage of orthodontic patients. The role of the orthodontist is important in screening the disease, making a provisional diagnosis, and referring it to a periodontist for immediate treatment. The orthodontist should be aware of the disease not only before starting the appliance therapy, but also during and after the active mechanotherapy. The orthodontic treatment plan, biomechanics, and appliance system may need to be modified to deal with the teeth having reduced periodontal support...

The treatment of Angle Class III malocclusion is rather challenging, because the patient's growth pattern determines the success of long-term treatment. Early diagnosis and treatment are still highly discussed issues in orthodontic literature. This type of early intervention has been indicated more frequently in order to eliminate primary etiological factors and prevent an already present malocclusion from becoming severe. However, when a patient is diagnosed in adulthood, manipulation of the bone bases becomes extremely limited, as there is no longer any potential for growth...

Management of growing patients with severe developmental jaw abnormalities can be very difficult. Early surgical intervention may be warranted in situations where function (e.g., mastication, swallowing, breathing, or speech) and/or psychological well-being could be negatively affected. Many surgeons and orthodontists are reluctant to recommend a surgical treatment option for growing patients with severe developmental jaw abnormalities because of their age. Specific surgical procedures can be performed during growth to correct developmental jaw abnormalities with predictable results...

BACKGROUND: With the development of 3D scanning technologies in dentistry, high accuracy optical scanning data from the crown and cone beam computed tomography (CBCT) data from the root can be acquired easily. In many dental fields, especially in digital orthodontics, it is useful to fuse the data from the crown and the root. However, the manual fusion method is complex and difficult. A novel automatic fusion method for two-source data from the crown and the root was researched and its accuracy was evaluated in this study...
