Incidence of bisphosphonate-related osteonecrosis of the jaws (BRONJ) in patients taking bisphosphonates for osteoporosis treatment - a grossly underestimated risk?

Purpose: The aim of this study was to detect the incidence of bisphosphonate-related osteonecrosis of the jaws (BRONJ) in association with osteoporosis in 2009 in the rural district of Marburg-Biedenkopf, Germany. In addition, the therapeutic regimen of dentists in this area was compared to the treatment guidelines of established international associations.

Methodology: A postal survey including 129 dental offices within the named investigation area was conducted.

3D analysis of condylar position after sagittal split osteotomy of the mandible in mono- and bimaxillary orthognathic surgery - a methodology study in 18 patients.

Objectives: This study analyzes the condylar position with intercondylar distance and angle after sagittal split osteotomy in mono- and bimaxillary orthognathic surgery applying cone-beam computed tomography (CBCT) images before and after surgery.

Materials And Methods: Data of 18 patients, ten males (mean age 28 years) and eight females (mean age 26 years) undergoing the described surgery between 2008 and 2009 were analyzed. CBCT scans were performed with the KaVo 3DeXam (KaVo, Biberach/ Riß, Germany) (identical with the iCAT scan device) before and after surgery.

Bone augmentation in dental implantology using press-fit bone cylinders and twin-principle diamond hollow drills: a case series.

Background: Bone transplants are mostly prepared with cutting drills, chisels, and rasps. These techniques are difficult for unexperienced surgeons, and the implant interface is less precise due to unstandardized preparation. Cylindrical bone transplants are a known alternative.
