Impaction of the gizzard was diagnosed in 33 1-to-4-wk-old lesser rhea (Pterocnemia pennata) raised on farms in Patagonia, Argentina. The birds showed anorexia, lethargy, constipation, dehydration, weight loss, and weakness. Necropsy revealed gizzard impaction by fibrous material, sand, rocks, and rubbish. Also, excess fibrous material was observed in the small intestine, and intussusception wa...

Objective: The purpose was to obtain information about the relation between agenesis and shape anomaly of maxillary lateral incisors and canine impaction. Methods: Seventy-three patients with canine impaction and 73 control patients, without canine impaction, were evaluated. The mesiodistal distances of the maxillary lateral incisors adjacent to the impacted canines and the correspondent mandib...

Cerumen impaction is common and saliently affects well-being Cerumen excreted from the skin of the external ear canal provides a protective oily layer, entraps foreign materials and has antibacterial properties. It is produced by special glands and usually is degraded in parallel, so in most people there is no wax accumulation. If a large quantity of wax is retained, it blocks the ear canal and...

Mandibular canine impaction and transmigration have serious consequences for the patient, as removal of the tooth or teeth in question is often the only solution. The loss of one or both mandibular canines complicates orthodontic treatment. Early warning signs of mandibular canine ectopia are explored in this paper as well as how to assess the potential for displacement, impaction and/or transm...

Impaction of third molar is a common developmental abnormality. However, ectopic impaction of the mandibular third molar in condylar region is an extremely rare condition. This report describes a case of impacted tooth in the mandibular condyle without any associated pathologic condition. Also, this report presents the spatial relationship of the impacted mandibular third molar to the surroundi...

The standard graft material for impaction bone-grafting is fresh-frozen femoral head allograft morselized to a particle size as large as is practical to ensure stability and allow new bone formation. The graft must be sufficiently compacted to provide immediate mechanical stability; this requires containment of the graft and substantial impaction energy. Diaphyseal bone fracture and excessive i...

The objective of this study was to investigate the potential application of cell-seeded biomaterials for revision arthroplasty and the reconstruction of major joints using the impaction grafting technique. Using morselized cancellous bone graft as a porous scaffold, MG63 cells were seeded on the scaffold and impacted into an acetabulum cup model using a mechanical device constructed from data o...

Introduction. Foreign body impaction (FBI) in the esophagus can be a serious condition, which can have a high mortality among children and adults, if appropriate diagnosis and treatment are not instituted urgently. 80-90% of all foreign bodies trapped in the esophagus usually pass spontaneously through the digestive tract, without any medical or surgical intervention. 10-20% of them will need a...

To date, treating vertical food impaction with open contact effectively, especially with an atraumatic therapy, remains a challenge. In this study, we developed a simple, atraumatic, and economic therapeutic measure to treat vertical food impaction. The scientific rationale of our therapeutic technique is to restore an intact and firm proximal contact with proper location and form relationships...
