Pure orbital fractures have the tendency to occur on medial wall and orbital floor; because these points are more fragile, the endoscopy can be utilized for accomplishing the task of repositioning the herniated content, as well as serving as an additional tool, helping to view the orbital defects through a transantral approach. The presented case is a female patient, 12 years old, who was diagnosed as having a pure blowout fracture, on right orbital floor, type trapdoor, with orbital content herniated toward the maxillary sinus...

Sinus augmentation with a lateral window technique and delayed implant placement are the traditional treatment schedules when the residual alveolar bone height in atrophic posterior maxilla is less than 5 mm. This article presents a transcrestal window approach (TWA) to replace a missing first molar in an atrophic posterior maxillary ridge with 1 to 2 mm of residual bone height (RBH). Transcrestal sinus augmentation and delayed implant placement were performed. The antral pseudocyst that was located in the nasal wall of the maxillary sinus disappeared in the cone-beam computer tomography images taken after sinus elevation surgery...

As life expectancy increases, a larger number of elderly people require dental health care attention for implant-supported rehabilitation, with the aim of restoring the function and aesthetics of the oral cavity. Most of these patients have lost their teeth long time ago, causing a severe bone resorption and maxillary sinus pneumatization. Therefore, the current study aims to demonstrate, through the description of the clinical case, the treatment with zygomatic implants as an option for treating severely atrophic maxillas...

INTRODUCTION: The term oro-antral fistula is understood to mean of fistular canal covered with epithelia which may or may not be filled with granulation tissue or polyposis of the sinus mucous membrane. With the presence of a fistula the sinus is permanently open, which enables the passage of microbial flora of the oral cavity into the maxillary sinus and the occurrence of inflammation with all possible consequences. Every now and then various researchers have proposed innumerable techniques to treat this defect...

BACKGROUND: Sinus lift is a bone augmentation procedure that improves the alveolar crest height in an atrophic posterior maxilla. However, the regenerated bone volume can vary and generally has a tendency to decrease after sinus operation. This article describes nongrafted maxillary sinus lift using a bioresorbable unsintered hydroxyapatite combined with poly L-lactide (HA/PLLA) mesh plate device and dental implant placement in an atrophic posterior maxilla, after which continuous bone gain was observed around the implant apex during a postoperative follow-up period of 3 years...

Rehabilitation of edentulous posterior maxilla with implant-supported prostheses frequently presents a challenge to dentists. This is due to insufficient bone within the region, in addition to other limiting factors such as anatomical pneumatization of the maxillary sinus. Thus, grafting of the maxillary sinus is a common procedure used to counteract these problems. Regardless of the type of biomaterial used, the success of the procedure is dependent on the formation of high-quality bone. Therefore, vascularization is a key factor for successful grafting and for the long-term maintenance of the treatment...
