BACKGROUND: Posterior maxillary tooth loss may complicate the implant treatment due to the alterations in alveolar anatomy and maxillary sinus pneumatization. This study aimed to comprehensively examine the anatomical structure of this region from cone-beam computed tomography (CBCT) images. MATERIALS AND METHODS: The posterior maxilla regions with single tooth loss were analyzed by dividing the variables into 3 subgroups from images of 597 patients chosen from 1160 CBCTs...

OBJECTIVE: The aim of the present study was to evaluate the principal anatomical characteristics of the maxillary sinus using Cone Beam Computed Tomography (CBCT) in order to facilitate prevention of intra- and post-operative complications. MATERIALS AND METHODS: Three hundred CBCT scans from patients undergoing implant surgery were analysed. The following anatomical structures were evaluated: (1) Residual ridge height (RRH) and width (RRW); (2) Ridge bone density (BD); (3) Maxillary sinus angle (MSA); (4) Maxillary sinus lateral wall thickness (LWT); (5) Schneiderian membrane thickness (MT); (6) Maxillary sinus septa (SS); (7) Posterior superior alveolar artery (PSAA)...

BACKGROUND: When considering dental implant rehabilitation in atrophic posterior sectors, the maxillary sinuses must be evaluated in detail. Knowledge of the anatomical variations and of the potential lesions found in these structures conditions the outcome of sinus lift procedures and therefore of the dental implants. A systematic review is made to determine the frequency of anatomical variations and pathological findings in maxillary sinuses among patients subjected to cone beam computed tomography (CBCT)...

PURPOSE: Sinus elevation procedures have become a routine and reliable way to gain bone volume in the edentulous maxilla for dental implant placement. Presence of bony septations and pathology in the maxillary sinus often cause complications leading to graft or implant failure or both. The aim of this study was to retrospectively evaluate the prevalence of pathology, direction of the septa, and sinus width measured at 2 mm, 5 mm, and 10 mm from the sinus floor in maxillary sinuses using cone-beam computed tomography (CBCT)...

PURPOSE: Preoperative assessment of maxillary sinus anatomy can prevent complications associated with sinus grafting or implant procedures. The purpose of this study was to measure the frequency, numbers, locations, orientations, and heights of maxillary sinus septa. MATERIALS AND METHODS: Reconstructed cone-beam computed tomographic images of 1,012 sinuses were analyzed using NewTom VG software (NNT 2.21, ImageWorks, Elmsford, NY). This cross-sectional study included patients who underwent radiography at the department of radiology...

BACKGROUND: The aim of this study was to simulate implant placement in the maxillary sinus septum, as a potential alternative site to avoid sinus grafting. MATERIAL AND METHODS: One hundred partially or completely edentulous patients, with their maxillary sinus septum present in the edentulous region, were selected from the database of the Department of Maxillofacial Surgery, Cliniques Universitaires Saint Luc, Bruxelles, Belgium. Three-dimensional (3D) reconstructions were created using 3D planning software...

INTRODUCTION: Maxillary sinus septas are barriers of cortical bone that arise from the floor or from the walls of sinus and may even divide the sinus into two or more cavities. Morphologically maxillary sinus septa are generally oriented in buccopalatinal orientation horizontal or sagittal orientation of the sinus septa is a rare condition. PRESENTATION OF CASE: This report presents two sinus lift case, in which observed septa in a horizontal orientation was presented...

OBJECTIVES: The aim of this study is to determine the incidence, location, and orientation of maxillary sinus septa in formalin embalmed cadavers. MATERIALS AND METHODS: The study was conducted on 210 cadaveric heads available in our department. After taking the mid-sagittal section the specimens were opened from the medial aspect and the sinus cavity was explored for the presence of maxillary sinus septa, their anatomical plane, location and dimensions.

MATERIALS AND METHODS: A focused question was developed to search the electronic databases MEDLINE, EMBASE, the Cochrane Oral Health Group Trials Register, and CENTRAL and identify all relevant papers published between 1980 and January 19, 2013. Unpublished literature at ClinicalTrials...

PURPOSE: Because the maxilla and its alveolar process are prone to resorption after tooth loss, it is often necessary to perform a bone augmentation procedure to successfully carry out implant treatment in that region. The aim of this study was to determine the adhesive force between the sinus membrane and the osseous sinus floor that occurs during sinus floor elevation with a balloon lift system. MATERIALS AND METHODS: Twenty-two ex vivo pig heads were used for this study...

PURPOSE: To investigate the value of using con-beam computer tomography (CBCT) to evaluate bone volume in the edentulous area of posterior maxilla, and guide sinus floor elevation. METHODS: Twenty eight patients who planed to receive dental implant in the posterior maxilla underwent CBCT scan. After analysis of residual bone height, 19 patients with 5-10 mm bone height below the sinus floor underwent transcrestal sinus floor elevation, while 7 patients with less than 5 mm bone height below the sinus floor underwent lateral window sinus floor elevation...

BACKGROUND: Extreme bone resorption in posterior maxilla may lead to absence of part of the sinus floor. This phenomenon has been termed sinus floor bone failure, and may compromise sinus floor augmentation. PURPOSE: The present article aims to evaluate risk factors related to sinus floor bone failures and to evaluate the influence of these failures in sinus floor augmentation outcomes in patients with severely atrophic posterior maxilla. MATERIAL AND METHODS: In this case-control study, patients were selected among those referred for sinus floor augmentation...
