Changes In Stress Distribution Of Orthodontic Miniscrew And Surrounding Bone At Different Angles And Heights - Fem Study, Miranda Mathews

Annual Research Symposium

Miniscrews is introduced as absolute anchorage devices in orthodontic treatment. They are efficient in overcoming anchorage loss. The miniscrew implants can be placed at different heights and angles in the positions determined for various clinical requirements. In this study, we used these parameters for determining the changes in stress distribution on the supporting bone and the miniscrews itself using finite element analysis.The aim of this study is to determine changes in stress distribution on the supporting bone and miniscrew implant at different alveolar crestal heights in different angulations using Finite Element Analysis.

Annual Research Symposium

To assess the possible three-dimensional changes in condylar volume in Class II Division 2 growing patients following the use of Invisalign clear aligners to “unlock” the mandible. Unlocking the mandible was done through proclining the maxillary incisors, correcting the overbite, and expanding the maxillary arch.

Comparative Evaluation Of Bone Thickness In Infrazygomatic Crest Region For Optimal Insertion Of Bone Screws : A Cbct Study, Kavya Mp

Annual Research Symposium

Infrazygomatic crest (IZC) is a palpable bony ridge running between the alveolar ridge and the zygomatic process of maxilla. IZC bone dimension is an important factor in the safety and stability of bone screws. IZC thickness depends on the site of insertion, angulation and height from the occlusal plane. This study embarks on a comprehensive Cone Beam Computed Tomography (CBCT) exploration, to assess infra zygomatic Crest bone thickness.

Our study aimed to evaluate and compare the dentoalveolar, skeletal,and soft tissue changes between the Forsus FRD and Twin Block appliance in the treatment of ClassII malocclusions.

Evaluating Pi Angle Efficacy Against Established Cephalometric Angular Parameters, Sumit Bohra

Annual Research Symposium

Cephalometrics is a cornerstone of orthodontic diagnosis. Numerous angularmeasurements are used to assess the anteroposterior jaw relation include the ANB angle, Betaangle, Yen angle, and W angle. However, these have limitations, leading to the development of thePi angle. Our study aimed to evaluate the predictability of the Pi angle in a South Indian populationand compare it with other established antero-posterior dysplasia indicators such as the ANB angle,W angle, Yen angle, and Beta angle. This comparison is crucial for determining the most accuratemethod for assessing sagittal skeletal discrepancies.

Dentofacial Effects Of Radiotherapy On Pediatric Population With Retinoblastoma, Kristi Truong

Annual Research Symposium

This literature review investigates the dentofacial consequences of radiotherapy in young patients with retinoblastoma by referencing current research. In addition, the management and rehabilitation of the dentofacial abnormalities, highlighting orthodontic, surgical, and prosthetic approaches, is examined. By understanding the changes of dentofacial development due to retinoblastoma treatment, effective management techniques can be implemented to resolve significant issues, relating to dental and skeletal relationship and facial appearance.

Referral Patterns Of Neonatal Healthcare Professionals For Cleft Lip And Palate Patients, Alyssa Morrow

Annual Research Symposium

Cleft Lip and Palate patients are some of the most vulnerable and complex orthodontic patients. They face a myriad of health challenges including psychological, nutritional, auditory, speech, airway, skeletal, and dental. Ideal comprehensive treatment for CLP patients is provided via multidisciplinary teams of healthcare providers. However, there is currently limited access to proper multidisciplinary care for CLP patients in the US, partly due to lack of education regarding available resources. For the most effective treatment and optimal outcomes, it is essential that coordinated care starts at birth and that parental education begins as soon as CLP is detected in utero. …
