To Do Or Not To Do? Slow Orthodontic Extrusion For Implant Site Development In Esthetic Zone At The Anterior Maxilla, Hui-Chen Tsai, Chung-Chen Jane Yao, Cheing-Meei Liu

Taiwanese Journal of Orthodontics

Slow orthodontic extrusion (SOE) for implant site development, was introduced in 1991. It has been more than 20 years since this treatment was applied in our clinical practice. In this paper, we investigate surgeon's expectation of SOE for special requirements of immediate implantation by a clinical case. We also review case reports/case series searched from PubMed and inspect the power of evidence of these reports from the integration of data collection, and try to define the value of SOE. If the SOE cannot eliminate at least one surgical procedure, we need to consider the necessity of SOE before implant surgery.

Bilateral maxillary lateral incisors were mesialized for space closure and substitution for maxillary central incisors. The morphology of maxillary lateral incisors was modified to mimic the maxillary central incisors. After treatment, both occlusion and esthetics was improved, and the patient was satisfied with the results.


A Comprehensive Diagnostic System For Orthodontists- Beyond Angle’S Classification, Ib Leth Nielsen Jan 2019

A Comprehensive Diagnostic System For Orthodontists- Beyond Angle’S Classification, Ib Leth Nielsen

Taiwanese Journal of Orthodontics

Traditionally orthodontists have used the classification system developed by Edward H. Angle in 1900 to describe the malocclusion of an orthodontic patient. This classification is very limited with respect to the information it provides and should be replaced by a more detailed and inclusive description of a patient’s malocclusion as well as the underlying biology. In this review article we propose a new technique that ensures all pertinent information gets considered and we suggest a systematic approach to a more differentiated orthodontic diagnosis. Our approach divides the diagnosis into clearly defined categories that bring together the clinical findings into a …

Leucine Supplementation In Cuprizone-Induced Oligodendrocyte Toxicity, Michael Ley Jan 2019

Leucine Supplementation In Cuprizone-Induced Oligodendrocyte Toxicity, Michael Ley

Williams Honors College, Honors Research Projects

Cuprizone is a copper chelator that induces demyelination in the central nervous system when fed to mice. This compound is thought to target Complex IV and disrupt mitochondrial metabolism leading to loss of myelin-producing oligodendrocytes. In this proposal, we further examine the chemical and toxicological properties of cuprizone. Immunofluorescence imaging and microarray data on MO3.13 cells treated with cuprizone revealed the possibility of alterations in lysosomal function, as well as mitochondrial disruption via mTOR and Electron Transport Chain (ETC) related pathways. Cell viability assays conducted suggest that addition of Branched-Chain Amino Acids, most commonly used from literature, leucine, can increase …
