OBJECTIVES The present study examines the influence of cavity type, and size of composite restorations on cuspal flexure due to polymerization shrinkage. METHODS Thirty healthy premolars were selected and divided into two experimental groups. Group 1: Mesial, mesio-distal, and MOD cavities were successively prepared in each tooth by means of the SONICSYS approx system (KaVo) using a n 2 (smal...

OBJECTIVE The purpose of this study was to compare the changes induced in the pharyngeal airway space by orthodontic treatment with bodily retraction of the mandibular incisors and mandibular setback surgery without extraction. METHODS This retrospective study included 63 adult patients (32 men and 31 women). Thirty-three patients who had been treated via four-bicuspid extraction and bodily r...

In the past year, the researchers at the Center for Electromechanics at The University of Texas at Austin (UT-CEM) and the Nanotech Institute at The University of Texas at Dallas (UTD) concluded research efforts on improved flywheel designs and flywheel materials to meet energy storage requirements for the grid. UT-CEM’s efforts focused on developing design codes and methods for incorporating h...

The mechanism of seismic-induced bedding rock landslide is distinct from that slope instability/landslide in normal gravity conditions; their failure modes are mainly characterized by vibration deterioration effect mass structural plane due to a seismic loading, which has significant on the stability landslide. Several advanced methods have been proposed assess earthquake-induced However, quant...

Simplified procedures are commonly employed to estimate seismic displacements of earth and waste fills. The landmark work of Makdisi and Seed (1978) has been widely adopted in practice. Although this work is widely used, it has a number of significant limitations such as decoupling the sliding block analysis from the seismic response analysis, use of a limited number of recorded earthquake moti...

This article is an ethnographic inquiry into the cultural dimensions of forced relocations. It based on experiences four resident anthropologists displacements at Tugwi-Mukosi in Masvingo province, Zimbabwe. Using concept death, we question idea belonging and what regarded as “honourable” way exiting this world. These are interwoven fabric most Zimbabwean communities any phenomenon that severs ...

PURPOSE The purpose of this study was to determine the long-term objective and subjective outcomes of temporomandibular joint (TMJ) implant surgery for the treatment of painful TMJ disc displacement using temporary Silastic (Dow Corning Corporation, Midland, MI), permanent Silastic, or Proplast (Vitek, Houston, TX) implants to replace the disc. These cases were compared with other cases of the ...

OBJECTIVES To examine the associated risk factors and results of treatment among patients who sustained graft displacement or migration after anterior cervical corpectomy surgery. SUMMARY OF BACKGROUND DATA Graft migration or displacement...
