Molar uprighting with T-loop springs.

Uprighting of molars is indicated as an adjunct to restorative and periodontal procedures. Limiting conditions exist in which previously reported helical and box-loop springs cannot be used effectively. In those instances, segmental arch wires with T-loops upright the molars efficiently while maintaining control in three planes of space. Furthermore, these loop designs permit immediate engagement of these appliances. Clinical experiences with these springs by students in the professional and graduate dental clinics at the University of Kentucky College of Dentistry lead to the conclusion that: segmental uprighting arch wires with T-loops are easy to fabricate and use; T-looped uprighting springs can be engaged immediately and used efficiently in instances in which helical spring or box-loop uprighting appliances are contraindicated; T-looped uprighting springs offer excellent controlled movements of teeth in three planes of space; acceptance by the patient is favorable; and treatment time, depending on the amount of tooth movement required, is rapid and varies between 8 to 16 weeks.

A vertical cephalometric analysis of the human craniofacial complex.

A vertical analysis involving ten linear measurements was developed to localize skeletal and dentoalveolar dysplasias. The measurements are of biologic relevance, reflecting the amount of growth harmony or disharmony to the examination and record-taking time. The vertical dimensional analysis uses the age- and sex-related University of Michigan mean values for comparative data for each measurement. Ratios were computed for a five-unit proportional analysis. Both analyses were applied to assess the vertical problems of three female patients. The analyses detected specific areas of dysplasia for each patient.

[Why not try to move on ankylosed tooth orthodontically?].

Due to presence of rigid inorganic matrix, mechanical perturbations cannot affect the bone blood supply or deform osteocytes. Because convincing evidence that bone can directly perceive mechanical forces in lacking, we hypothesize that mechanical perturbations can only elicit remodeling by acting through a soft tissue envelope. These soft tissue envelopes are the periodontal ligament, periosteum, fibrous tissues that can form around implants, sutures and the like. Fibroblast, preosteoblast, and mesenchymal cells are composing the envelopes. It is possible that these cells are indeed responsible for bone remodeling subsequent to forces application.
