BACKGROUND All clinicians are aware of the difficulty of installing a dental implant in posterior maxilla because of proximate position of maxillary sinus, insufficient bone width, and lower bone density. This study is to examine which factors will make the implantation in the posterior maxilla more difficult, and which factors will affect the postoperative implant stability in this region. M...

OBJECTIVES The posterior maxillary region often provides a limited bone volume for dental implants. Maxillary sinus elevation via inserting a bone graft through a window opened in the lateral sinus wall has become the most common surgical procedure for increasing the alveolar bone height in place of dental implants in the posterior maxillary region. The purpose of this article is to assess the ...

BACKGROUND Various attempts have been implemented using different materials and techniques to augment the maxillary sinus floor for prospect dental implant positioning. AIM This contemplate was conducted to assess the osteogenic capability of the maxillary sinus in a two-step sinus membrane elevation using titanium mesh to keep the formed space to place dental implants in atrophic ridges. M...

Rehabilitation of the atrophied edentulous maxilla is complicated. Often the residual bone height is insufficient for implant placement due to crestal bone resorption and pneumatization of the sinus.The meticulous management of the available residual bone, the atraumatic sinus lifting procedure, and the proper selection of the implants are the keys to successful dental implantation in resorbed ...

Sinus floor elevation has become a standard procedure in patients affected by severe maxillary atrophy, before implant placement, provided that the maxillary sinus is intact and uninfected. In the case of an oroantral fistula, simple soft tissue closure may interfere with the process of elevating the Schneiderian membrane. Total regeneration of the bony sinus floor is necessary to prevent disru...

The aim of this study is to evaluate the performance of implant-derived minimally invasive sinus floor elevation. A multicenter retrospective study was performed in 5 dental clinics. Patients requiring sinus augmentation for single implant placement were recorded and followed up. The dental implant used in this trial was a self-tapping endosseous dental implant that contains an internal channel...

Acute coronary syndrome with precordial ST segment elevation is usually related to left anterior descending artery occlusion, although isolated right ventricular infarction has been described as a cause of ST elevation in V1-V3 leads. We present a case of a patient with previous inferior wall infarction and new acute ST elevation myocardial infarction (STEMI) due to proximal right coronary thro...
