Successful implant treatment includes osseointegration as well as prosthetically optimal positions of the implants for esthetics and function. Computer-assisted oral implant surgery offers several advantages over the traditional approach. The purpose of this report was to evaluate a complex case of a 28-year-old female patient who lost all her teeth as a result of a aggressive periodontal disea...

Dental radiology has long played an exciting and critical diagnostic role in dentistry. Recent decades have seen the development of computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine and ultrasonography imaging modalities that have revolutionized dental and medical diagnosis. 1 Despite the development of these novel imaging modalities, the role of conventional radiogra...

• If there is clinical or radiographic suspicion of AOD, CT of the craniocervical junction is recommended. The CCI determined on CT has the highest diagnostic sensitivity and specificity for AOD among all radiodiagnostic indicators in pediatric patients. The utility of CCI in adult patients has not been reported. • A lateral cervical radiograph is recommended for the diagnosis of AOD. If a radi...

Subperiosteal implants are generally used in the severely resorbed areas, and although dwindling in use, they have shown to be successful treatment options for the edentulous dental patients. We report a case of maxillary subperiosteal implantitis that caused sinusitis. A 59-year-old man was referred to our clinic in March 2003 with a chief complaint of pain and swelling in the bilateral upper ...

When a patient presents with a partially edentulous arch, fixed res-toration of the arch supported by dental implants and natural teeth requires proper planning and provisionalization. First, information must be obtained to help plan the case for function and aesthetics. Study models must be articulated so that the present occlusal relationship can be analyzed. Diagnostic wax-ups and intraoral ...

No longer merely a concept for the future, the use of digital technologies in dentistry has become common practice today. Computed tomography (CT)-guided dental implant surgery has greatly expanded over the past decade as concepts and techniques have become increasingly refined and more implant manufacturers have adapted their implant systems to these new technologies. The All-on-4® technique f...

Dental implants have become part of routine treatment plans in many dental offices because of their increasing popularity and acceptance by patients. Appropriate preplacement planning, in which imaging plays a pivotal role, helps to ensure a satisfactory outcome. The development of precise presurgical imaging techniques and surgical templates allows the dentist to place these implants with rela...

In this paper, a new approach for segmenting different anatomical reg ions in dental Computed Tomography (CT) studies is presented. The approach consists of three steps: Hounsfield unit's threshold (HU) based on gray-level segmentation, multi-object with textu re extraction and anatomical regions identification. First, a HU threshold window sets to separate between different regions upon their ...

Background: A comprehensive database, comprising geometry and properties of human teeth, is needed for dentistry education and dental research. The aim of this study was to create a three-dimensional model of human teeth to improve the dental E-learning and dental research. Methods: In this study, a cross-section picture of the three-dimensional model of the teeth was used. CT-Scan images were ...

The availability of in office Cone Beam CT (CBCT) scanners, dental implant planning software, CAD CAM milling, and rapid printing technologies allow for the precise placement of dental implants and immediate prosthetic temporization. These technologies allow for flapless implant placement, or open flap bone reduction for "All on 4" techniques with improved preoperative planning and intraoperati...
