RESUMO

This retrospective clinical study sought to evaluate the survival of immediate implants placed at maxillary and mandibular single-rooted tooth extraction sites and to determine the relationship among implant size, placement site, and implant survival. Between January 2010 and June 2011, 85 patients [33 males, 52 females; mean age: 45 years] underwent immediate implant placement after extraction of single-rooted teeth. All implants were restored between 12 and 14 weeks after implant placement. The implant survival and its relationship with implant size and implantation site were evaluated by odds ratios [ORs]. Implants were placed at the following sites: upper central incisor [UCI, n = 35], upper lateral incisor [ULI, n = 27], upper second premolar [U2ndP, n = 36], lower incisor [LI, n = 53], and lower premolar [LP, n = 22]. Implants of the following sizes were used: 5 × 10 mm [n = 24], 5 × 8 mm [n = 21], 4.3 × 10 mm [n = 77], 4.3 × 8 mm [n = 36], 3.5 × 10 mm [n = 12], and 3.5 × 8 mm [n = 3]. After a mean follow-up time of 47 months, the overall implant survival rate was 96%. Survival rate was highest at the LI site [98.1%] and lowest at the ULI site [92.6%]. All of the 5-mm implants survived [100%], as did most of the 4.3 × 10 mm implants [96.1%]. Implants of 4.3 × 8 mm and 3.5 × 10 mm were the least successful [91.7%]. Mandibular implants had a better survival rate [97.3%] than maxillary implants [94.9%]. There was no significant OR of increased survival for any particular implant size or site. Immediate implant placement in fresh extraction sockets can give predictable clinical outcomes, regardless of the implant size and site of placement

RESUMO

Bartter's syndrome is an unusual [estimated incidence is 1.2 per million people] but important congenital form of secondary hyperaldosteronism; due to abnormalities in renal handling of electrolytes. It is associated with hypertrophy and hyperplasia of the juxtaglomerular cells, normal blood pressure, and hypokalemic alkalosis withoutedema. We present a 22-year-old woman with Bartter's syndrome underwent bilateral sagittal split osteotomy to correct mandibular prognathic. The anesthetic management of Bartter's syndrome should be relevant to the pathophysiology of the syndrome. Therefore, it should be directed toward maintaining cardiovascular stability, control of associated fluid, electrolyte and acid-base derangements, and the prevention of renal damage
