OBJECTIVES The impaction of the second mandibular molar (MM2) has recently become more prevalent. Several etiological hypothesis have been proposed to investigate the association between skeletal features and impaction of MM2. The aims of this study were to analyze the skeletal features in patients with MM2 impaction and the association between arrested eruption of MM2 and the presence of the t...

Acute as well as chronic and recurrent colic episodes were caused by right dorsal colon (RDC) impaction in 7.98% of all colic patients. Significantly higher statistical evidence was figured out in hucul horses, mares and 7-year-old animals. Diagnosis of RDC impaction was established on the basis of rectal palpation (68.75%) or laparotomy (31.25%). Yield of rectal palpation was limited by a diff...

Objective: The aim of this study was to document the prevalence of maxillary permanent canine impaction in relation to anomalous adjacent lateral incisors in a Turkish population. Materials and Methods: Pretreatment orthodontic records of 68 subjects (27 male, 41 female) with palatal or buccal impaction of one or both permanent maxillary canines were included in this study. Localization of the ...

in recent years, more attention is paid to stainless steel 316l as fracture plate and fixation in human's body. present studies are focused on surface and metallurgical properties of this material. biocompatibelity of this material and its superior mechanical properties has made it the most demanded biomaterial. in this research, four different implants are investigated in three stages. four co...

Impaction syndromes related to ulnar-sided pain include ulnar impaction syndrome, ulnar impingement syndrome, ulnocarpal impaction syndrome secondary to nonunion of the ulnar styloid process, ulnar styloid impaction syndrome, and hamatolunate impingement syndrome. The most common of these, ulnar impaction syndrome, is a degenerative condition of the ulnar side of the wrist related to excessive ...

Ileal impaction is prevalent in the south-eastern USA, where feeding of Coastal Bermuda hay has been implicated as a risk f a c t o r. A l t e r n a t i v e l y, infection with the tapeworm Anoplocephala perfoliata has been identified as a risk factor f o r ileal impaction in the UK. We hypothesised that feeding Coastal Bermuda hay and failure to administer routinely an anthelmintic with effica...

Dysphagia is a well-recognized complication of stroke. We report two cases of dysphagia in stroke patients caused by the pharyngeal impaction of dental prostheses. Radiologic identification of such impaction is unreliable due to the increasing use of radiolucent material in dental prostheses. We recommend direct or indirect laryngoscopy to exclude foreign body impaction in all patients complain...

BACKGROUND Osteochondral autografts and allografts require mechanical force for proper graft placement into the defect site; however, impaction compromises the tissue. This study aimed to determine the effect of impaction force and number of hits to seat the graft on cartilage integrity. HYPOTHESIS Under constant impulse conditions, higher impaction load magnitudes are more detrimental to cel...

OBJECTIVE To evaluate the seasonal influence, signalment, type of hay consumed, clinical examination findings, and outcome after surgery for horses with ileal impaction. STUDY DESIGN A retrospective study. RESULTS Between 1988 and 1993, 28 horses had surgical correction of ileal impaction. There was a significantly higher rate of ileal impaction during the Fall (September-November, P = .004...

Impaction of the stomach typically consists of excessive dry, fibrous ingesta, but may also be composed of ingested materials that form a mass, such as persimmon seeds or mesquite beans. Other feeds that tend to swell after ingestion, including wheat, barley, and sugar beet pulp, may also cause impaction. Furthermore, dental disease may increase the likelihood of gastric impaction because of im...
