Endosseous implants are frequently used for prosthetic reconstruction in the edentulous patient. Sufficient volume and density of the alveolar bone for implant integration and load bearing are prerequisites for good clinical outcome. Bone resorption following the extraction of posterior maxillary teeth sometimes results in severe loss of bone in vertical and ⁄ or horizontal dimensions, which ma...

The objective of this study was to investigate the influence of maxillary alveolar bone on the stress distribution of zygomatic implants. A three-dimensional finite element model was created of half of a skull. Two zygomatic implants were modelled, placed in the skull supported by the zygomatic bone and the maxillary alveolar bone and connected by a fixed bridge. This model was duplicated, and ...

This study measured maxillary sinus volume as an aid in determining the volume of graft bone needed before grafting autogenous bone to the maxillary sinus floor. Maxillary sinus volumes were measured from computerized tomographic images of 38 sinuses using a 3-dimensional reconstruction system. When the sinus-lift procedure was simulated, volumes (mean +/- SD) of the inferior portion of the sin...

Pneumatization of maxillary sinus causes insufficient vertical bone volume on posterior maxilla. So the restoration of edentulous posterior maxilla with dental implants is challenging due to a deficient posterior alveolar ridge, unfavorable bone quality and increased pneumatization of the maxillary sinus.1 For maxillary sinus augmentation, the crestal approach and the lateral window approach ha...

The maxillary posterior edentulous region presents a challenge when planning for restoring missing teeth with a dental implant. The available bone in such cases is often not dense and not adequate for the placement of a properly sized implant because of maxillary sinus pneumatization and alveolar bone loss. Maxillary sinus lift is a predictable procedure to provide adequate bone height for the ...

PURPOSE To evaluate the effect of platelet-rich plasma (PRP) on autogenous bone graft remodeling during sinus augmentation in a rabbit model. MATERIALS Twelve New Zealand White rabbits were divided randomly into 3 groups based on their time of sacrifice (2, 4, and 8 weeks). All animals underwent a general anesthetic and harvesting of an autogenous bone graft from the right iliac crest with su...

Introduction: Coverage of bone grafts is very important in reconstructive surgery. In edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. Here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for up...

Mucosal fenestration associated with maxillary first molar is rare but challenging to treat when there loss of marginal bone along buccally oriented root angulation. The exposed within the oral cavity large mucosal defect makes it susceptible plaque accumulation and infection. This case report showcases management mesiobuccal Left Maxillary by resection Platelet rich fibrin membrane.

In the present study, the question of whether a relatively non-specific epithelial requirement exists for membrane bone formation within the maxillary mesenchyme was investigted. Organ rudiments from embryonic chicks of three to five days of incubation (HH 18-25) were enzymatically separated into the epithelial and mesenchymal components. Maxillary mesenchyme (from embryos HH 18-19) which in th...

To provide an anatomical basis for clinical implant esthetics, we evaluated the morphology of the nasopalatine canal (NPC) and analyzed labial and interproximal bone anatomy at the maxillary anterior region. We sought to investigate the effect of maxillary protrusion and tooth labiolingual inclination on labial bone anatomy in Chinese adults. Three dimensional (3D) images were reconstructed usi...
