Maxillary reconstruction is a common procedure in maxillofacial surgery; for this purpose is used autogenous bone, alloplastic bone or another one with different results. In all of them, traditionally the use of computed tomography is used to make the surgical plan, however, 3D models are not used frequently. This report show a new application of the stereolithography to anticipate the surgical...

OBJECTIVE The purpose of this study was to evaluate the histomorphometric result from maxillary sinus augmentation with calcium phosphate nanocrystal-coated bovine bone (Biocera). STUDY DESIGN Maxillary sinus augmentations were performed on 10 patients with the delayed placement of implants. The lateral bony window was created using a piezoelectric saw, and the sinus membrane was elevated to ...

Introduction: The aim of this study was to evaluate the effect of platelet-rich fibrin (PRF) on the quality and quantity of bone formation in unilateral maxillary alveolar cleft reconstruction using cone beam computed tomography.   Materials and Methods: This study was conducted on 10 non-syndromic patients with unilateral cleft lip and palate within the age group of 9-12 years. The study popul...

PURPOSE The aim of this study was to prospectively evaluate the status of implants, marginal bone loss, and outcome of maxillary sinus floor augmentation in patients undergoing maxillary sinus lift and simultaneous implant placement with the use of bone grafts harvested adjacent to the actual surgical site. MATERIALS AND METHODS Patients in need of maxillary sinus floor augmentation to enable...

Bone graft are used in dentistry for the reconstruction of severely atrophic jaws. Fresh frozen bone has no osteogenic property but it has osteoconductive and osteoinductive properties because its matrix contains growth factors such as vascular endothelial growth factor. The purpose of the present study was to evaluate morphological and protein expression characteristics of fresh frozen bone be...

The maxillary sinus lift technique consists in grafting a bone substitute below the sinus membrane to achieve sufficient thickness for implant stability. The golden standard as a bone substitute is the patient's autologous bone, which is not only fully biocompatible but is also able to stimulate bone regeneration through the osteoinductive factors it contains. Nonetheless, it has to be withdraw...

BACKGROUND The long-term stability of maxillary sinus floor augmentation with β-TCP remains largely unknown. We report the long-term assessment of volumetric changes in maxillary sinus floor augmentation with β-TCP by cone-beam computed tomography (CBCT). METHODS The subjects included 30 patients who underwent maxillary sinus floor augmentation using β-TCP and 58 implant placement for unilate...

OBJECTIVE To determine the value of measuring maxillary length at 11-14 weeks of gestation in screening for trisomy 21. METHODS In 970 fetuses ultrasound examination was carried out for measurement of crown-rump length (CRL), nuchal translucency and maxillary length, and to determine if the nasal bone was present or absent, immediately before chorionic villus sampling for karyotyping at 11-14...

OBJECTIVE To evaluate the use of autogenous maxillary bone for the repair of orbital floor defects secondary to blunt facial trauma. DESIGN Retrospective case series of 41 patients with a mean follow-up of 1.7 years. SETTING Major metropolitan teaching hospital. PATIENTS Forty-one consecutive patients who underwent repair of orbital floor fractures with maxillary antral wall bone grafts. ...

This clinical report presents a simplified surgical procedure for accessing the maxillary sinus antrum via lateral and crestal approaches, which reduces the potential for sinus membrane perforation and subsequent complications when graft materials and dental implants are placed into the sinus. Due to visual limitations, perforations and associated complications can jeopardize the success rate o...
