Coronary sinus blood flow was studied by the continuous thermodilution method in 13 subjects with normal coronary arteries and 14 patients with coronary artery disease during progressive elevation of the heart rate by atrial pacing. In 11 patients of the coronary group angina pectoris developed during pacing. In subjects with normal coronary arteries the coronary sinus blood flow rose proportio...

PURPOSE This study describes the use of an innovative dynamic implant valve approach (DIVA) for dental implant placement and sinus augmentation procedures. MATERIALS AND METHODS The DIVA implant system was tested in vitro for leakage and mechanical fatigue. A closed sinus elevation procedure with a gel-type bone substitute was performed using the DIVA implant in a swine model (n = 6). Implant...

AIM OF THE STUDY To present the results of a prospective study on the management of infectious complications following maxillary sinus floor elevation procedures with a combined endoscopic (FESS) and intra-oral approach. MATERIALS AND METHODS From 2005 to 2009, twenty consecutive patients were diagnosed for sinusal chronic infectious complications refractory to medical treatment following max...

Posterior maksiller bölgede kemik hacmi ve kalitesinin yetersiz olması nedeniyle implant yerleştiriminde zorluklarla karşılaşılabilmektedir. Bu bölgelerde başarılı implant yerleştirimi için krestel yaklaşımla sinus tabanının yükseltilmesi başarı ile uygulanmaktadır. Osteotom adı verilen aletler ile lateral duvar genişletilir ve kondense edilir. Bunu sinus tabanının yukarı doğru kırılarak itilme...

UNLABELLED Maxillary sinus floor elevation is generally accepted as a regenerative procedure to facilitate dental implants placement in the posterior atrophic maxilla. Although the sinus lift procedure is relatively safe, some potential problems could be occur. The most prevalent intraoperative complication is perforation of sinus membrane, which can lead to graft infection and early failure. ...

For more than 30 years the maxillary sinus augmentation graft has been a mainstay of implant-directed maxillary reconstruction. The purpose of this article is to review the fundamentals of maxillary sinus reconstruction including anatomy and physiology of the sinus, indications for surgery, preoperative evaluation, surgical techniques, and management of complications. While there are some relat...

BACKGROUND Sinus lift is a bone augmentation procedure that improves the alveolar crest height in an atrophic posterior maxilla. However, the regenerated bone volume can vary and generally has a tendency to decrease after sinus operation. This article describes nongrafted maxillary sinus lift using a bioresorbable unsintered hydroxyapatite combined with poly L-lactide (HA/PLLA) mesh plate devic...

The aim of this study was to evaluate the implant survival rate, marginal bone loss, and surgical prosthetic complications implants placed through sinus floor elevation tilted engaged in basal bypass maxillary sinus. Sixty patients were enrolled for study. According residual height posterior maxilla, sample divided into three groups 20 patients: Group A (lateral elevation), B (transcrestal C (t...
