objectives: the purpose of this study was to determine buccal bone and soft tissue thicknesses and their correlation in the maxillary anterior region using cone beam computed tomography (cbct). materials and methods: in this cross sectional study, 330 sound maxillary incisors in 60 patients with a mean age of 37.5 years were assessed by cbct scans. for better visualization of soft tissue, patie...

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.

introduction: gold standard for alveolar cleft bone grafting is autogenous bone. advantage of adding the growth factors to the bone is established, so adding prf to the autogenous bone may have beneficial effects. methods:  platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. results:  autogenous bone in all (four cases) was...

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 ...

Introduction: Knowledge of the presence of the alveolar antral artery in the lateral maxillary sinus wall is essential for surgeons who operate in this region. The purpose of this study was to investigate the correlation between alveolar antral artery diameter and lateral maxillary bony wall thickness in dentate patients.   Materials and Methods: Thirty five Cone-Beam Computed Tomography (CBCT)...

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...

Objectives Maxillary implant-supported over-denture is a suitable treatment where conventional denture cannot be used. Few studies are available on maxillary over-denture while more are available on mandibular over-denture with no literature referring to attachment selection in maxillary over-dentures. The objective of this literature review was to see attachment selection strategies in maxill...

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...
