“…The maxillary sinus is a cavity containing air that has the radiolucent radiographic appearance of an oval or rounded shape and a well‐defined contour delimited by a radiopaque line and the cortical sinus. After tooth loss in the posterior maxillary region, this structure undergoes a process of bone resorption and, simultaneously, of progressive pneumatization of the maxillary sinus.…”

Objective: To analyse the number of septa in the maxillary sinuses using computed tomography (CT) in correlation with gender, age and the presence of teeth in the region. Materials and methods: The sample consisted of 300 CT scans obtained from a private radiology clinic between 2009 and 2011. The CT scans included in the study should have the appropriate image of the maxillary sinus and contain information regarding age, gender and the date of the examinations. Patients with a history of pathologies in the region, patients who underwent floor of mouth surgery and patients less than 20 years of age were excluded from the sample. The authors considered osseous septa to be septa with a height above 4 mm in relation to the base of the sinus floor. The sample was divided into three groups: (i) presence of all teeth, (ii) partially edentulous -a minimum of two teeth present between the second premolar and second molar -and (iii) totally edentulous. The data were divided and stratified by age and gender. Results: The frequency of septa in the maxillary sinus was 37.80% (n = 183). No significant difference was observed among the five age groups (P > 0.05); additionally, there was no significant difference in septa frequency (P > 0.05) -analysis of variance (ANOVA), Tukey's. Univariate and multivariate ANOVA showed a significant interaction between tooth loss and age (P < 0.05). Conclusion: Statistical analyses demonstrated no difference in the number of septa in relation to age, gender or the number of teeth in the posterior maxilla. Clinical relevanceAfter tooth loss, the posterior maxillary alveolar bone suffers intense resorption and pneumatization of the maxillary sinus. These events reduce the available volume of the bone conventional dental implants fixation. Several surgical techniques are used in accessing the sinus floor to increase the membrane and attach the implant. The presence of bony septa increases the risk of surgical complications and requires surgical experience from the professional. This article evaluated the frequency of septa in 300 computed tomography scans, correlating gender, age and presence or not of teeth. It was concluded that the frequency of the septa is high and no correlation was found.

“…In this study, 3 cases were excluded from the analyses because of the presence of multiple dental implant bodies with metal ceramic crowns in areas around lesions, causing large beam-hardening artifacts. However, the development of CBCT devices and imaging protocols have allowed for the reduction and correction of these artifacts (22), improving the conditions for following up dental treatments (23).…”

“…Using a particulate graft such as DFDBA helps bridging the minute gaps between cortical block and native bone, thus resulting in a more uniform and aesthetic alveolar ridge, in addition to providing osteoinductive effect [10, 11]. Particulate grafts also have the advantage of rapid vascularization; however, they must be protected by a membrane to reduce the risk of resorption.…”

Deficiencies in the alveolar ridges cause multiple problems in achieving aesthetic and functional outcome of implant therapy and are commonly restored by using onlay graft from intraoral source. Careful assessment of the recipient as well as the donor site using cone beam computed tomography (CBCT) is a prerequisite to ideal treatment planning. This paper highlights the critical role of CBCT in planning a successful rehabilitation of traumatised deficient anterior maxillary alveolar ridge using autogenous block graft from mandibular symphysis, followed by implant placement. A 21-year-old male reported with missing right maxillary lateral incisor due to traumatic avulsion 6 months back. A concavity was found on the labial aspect of edentulous area. Serial transplanar images on CBCT revealed gross irregular radiolucency in place of labial cortical plate. Using CBCT, size of the required block was estimated, and mandibular symphyseal area was evaluated for the feasibility of harvesting a graft of suitable dimension. Onlay block graft was harvested from mandibular symphysis and placed at the edentulous site to augment the alveolar ridge. Implants were placed 5 months later and loaded successfully after osseointegration. After 1 year of followup, implant-based prosthesis is working well, without any complications.
