_Since its introduction, sinus floor augmentation has generated great interest in the international scientific community and been subject to many changes in procedure. The first documented maxillary sinus augmentations using bone grafts date back to the work of Philip J. Boyne in the 1960s.1 An access osteotomy to elevate the sinus membrane can be performed by a vestibular or a crestal approach...

Objectives: This study aimed to calculate the volume of maxillary sinus and grafted part it with different modes three-dimensional reconstruction software. Materials Methods: retrospective volumetric cone-beam computed tomography was carried out on 21 patients/ 36 sinuses who had undergone lift surgery using a lateral approach, between 2010 2016 at Department Periodontology. All statistical ana...

background and aim . vertical and horizontal bone resorption of the alveolar ridge are common in edentulous jaws. in the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. sinus floor augmentation is an established way of increasing the height and volume of bone in the posterior region of the maxilla, which increa...

We retrospectively reviewed a new preimplantation regenerative augmentation technique for a severely atrophic posterior maxilla using sinus lifting with simultaneous alveolar distraction, together with long-term oral rehabilitation with implants. We also analyzed the regenerated bone histomorphologically. This study included 25 maxillary sinus sites in 17 patients. The technique consisted of al...

Physiol. 2N3(1): ,)174-179. 1970.-The sequence of contraction and augmentation patterns in contractile force of the sinus and conus regions of the right ventricle were analyzed under control, vagal, and sympathetic stimulation as well as norepinephrine infusion states. The no...

PURPOSE The present study investigates sinus membrane rupture in direct maxillary sinus lift with the rotary technique and with ultrasound, examining the survival of implants placed after sinus augmentation, and analyzing the bone gain obtained after the operation and 12 months after placement of the prosthetic restoration. MATERIALS AND METHODS A retrospective study was made of 45 patients r...

J Korean Assoc Oral Maxillofac Surg 2012;38:110-5) Ankylosed tooth is defined as ‘the discontinuance of normal passive tooth eruption without any mechanical barrier’. Ankylosed tooth treatment is a challenge to dental clinicians. In treatment of maxillary molar ankylosis cases there are risks of oro-antral fistula, displacement of root fragments into the maxillary sinus, as well as the necessit...

OBJECTIVES Knowledge and evaluation of the maxillary sinus anatomy before sinus augmentation are essential for avoiding surgical complications. Posterior superior alveolar artery (PSAA) is the branch of maxillary artery that supplies lateral sinus wall and overlying membrane. The aims of this study were to examine the prevalence, diameter, and location of the PSAA and its relationship to the al...
