The presence of vital bone after maxillary sinus augmentation is crucial to enhance the quality of bone-implant interface, ensuring predictable long-term results. The aims of this RCT with split-mouth design were the histologic and histomorphometric comparison of two different biomaterials in sinus elevation after 6 months of healing and the evaluation of the clinical outcomes of implants inser...

A variety of surgical techniques and materials have been developed to increase the vertical bone height in the posterior maxilla. Minimally invasive crestal approaches for the elevation of the floor of the sinus using a crestal approach have been recently reported to minimize adverse events associated with the use of the osteotome technique for indirect sinus lift. The aim of this study is to r...

PURPOSE To evaluate the frequency, morphology, and locations of maxillary sinus septa using cone beam computed tomographic (CBCT) imaging of the entire maxillary sinus and to analyze factors influencing the presence or absence of septa. MATERIALS AND METHODS CBCT images of the maxilla taken during a 1-year study period (October 1, 2012, to September 30, 2013) were evaluated for the presence a...

PURPOSE This prospective longitudinal study reports on the results in patients given autologous tooth material for augmentation in a sinus elevation procedure. MATERIALS AND METHODS Six patients with inadequate bone supply for augmentation in the maxillary posterior tooth region and at least one impacted maxillary third molar underwent sinus elevation surgery with lateral access using the par...

The objective of this study was to compare the alveolar bone growth in the 2 sides of the maxillary sinus after bilateral sinus lift procedures were performed with the simultaneous placement of dental implants in 20 consecutive patients. After elevation of the Schneiderian membrane, one side had only platelet-rich plasma (PRP) gel applied, while the other had placed only alloplastic graft mater...

Antral pseudocyst (AP) is a process formed by the inflammatory exudate accumulation below the sinuses mucous membrane and causing a sessile elevation. AP is a dome-shaped, well-delineate, faintly radiopaque lesion on the intact floor of the maxillary sinus. A case of AP with an unusual location is presented. A 24-year-old male was submitted to the panoramic radiographic exam and an around, well...

We present a case of atrial repolarization waves from an ectopic atrial rhythm mimicking inferior ST segment elevation myocardial infarction in a 78-year-old male patient who presented with left sided chest wall and shoulder pain. His ischemic workup was negative, and the ST elevations completely resolved upon the resumption of sinus rhythm before discharge.

On admission the physical examination was normal with a blood pressure of 130/90 mmHg. The initial electrocardiogram (Figure 1A) showed sinus rhythm with convex-upwards ST segment elevation (transmural injury) decreasing from V1 to V3 and acute inferior myocardial infarction pattern with Q waves and ST segment elevation of transmural injury in leads III and aVF. The patient was medicated with a...

BACKGROUND We present a case of a patient with multinodular goiter disease who suffered asystole during head hyperextension for surgical positioning on the operational table. CASE PRESENTATION Manipulation of carotid sinus may trigger bradycardia or even asystole even in patients without prior history of carotid sinus hypersensitivity. The time proximity between patient positioning and asysto...

Aim: This study aimed to evaluate the clinical complications that might be presented with osteotome and densah burs, as well assess new bone generated at 6 months post-operatively using CBCT. The hypothesis was bur would show comparable results osteotome-mediated sinus lifting. Material method: Ten patients were enrolled in atrophied maxillary posterior edentulous area required rehabilitation i...
