Homologous bone has been considered a viable alternative in bone reconstruction in the posterior maxillary area to perform surgeries for the maxillary sinus lifting. The aim of this study was to perform a literature review about the advantages and risks inherent in the use of homologous bone graft coming from the tissue bank to perform the surgery for maxillary sinus lifting. A literature revie...

Background  Many biomaterials are used during the open sinus lift surgery, beneath the elevated scheniderian membrane and maxillary sinus bony floor but the search for Ideal material continues. Methods  In the maxillary posterior atrophic ridges with the bone height less than four millimeters the open sinus lift surgery performed. The autologous Platelet-rich plasma (PRF) was used as the sol...

BACKGROUND The initial thickness of maxillary bone has significant impact on the responding level of facial bone and soft tissue after extraction and immediate implant placement. A prevailing notion is that following implant placement in fresh extraction sites, at least 2 mm of facial bone is needed to prevent soft tissue recession, fenestration, and dehiscence. PURPOSE The purpose of this st...

OBJECTIVES The purpose of this study was to evaluate the sinus bone graft resorption over 3 years after two-stage implant placement. MATERIALS AND METHODS The subjects for this study included 30 patients whose maxillary posterior ridges were too atrophic for implants. Bone-added osteotome sinus floor elevation was used in 15 maxillary sinuses, while the bone graft by lateral approach techniqu...

Maxillary sinus augmentation with a lateral approach (MSA) is well-established treatment. In this prospective study, we evaluated risk factors for postoperative bone graft displacement and reported the clinical application of long-term resorbable L-lactic acid/-caprolactone (PLA/PCL) as barrier membrane to cover open window in wall MSA. Twenty-four patients underwent MSA according relevant crit...

The formation of membrane bone from neural crest-derived mesenchyme of the maxillary and mandibular processes of the embryonic chick depends upon prior interactions between the mesenchyme and maxillary or mandibular epithelia. The present study explores the specificity of these interactions using tissue recombinations between heterotypic epithelia and mesenchyme. Mandibular and maxillary mesenc...

We report a case of a mucoepidermoid carcinoma associated with a maxillary cyst. The patient was an 18-year-old man presenting with the chief complaint of left buccal swelling. The left maxillary third molar was semi-impacted in the direction of the crown on the buccal side. Orthopantomography revealed a cystic radiolucency extending over a wide area, ranging from the left maxilla to the maxill...

9 T estoration of the atrophied edentulous maxilla poses great dilemma to the oral and maxillofacial surgeon nd restorative dentist. Conventional removable denure prostheses are adequate for some individuals; but mproved technology in dental implantology has led any to request alternative approaches with imlants. Patients with adequate maxillary bone are deal candidates for implants, but are th...

The maxillary posterior area is the most challenging site for the dental implant. Although the sinus graft is a predictable and successful technique for rehabilitation of atrophic and pneumatized posterior maxilla, when there is severe destruction of alveolar bone, a very long crown length remains challenging after successful dental implants installation with sinus graft. We performed vertical ...
