Dental implant–abutment systems are used as anchors to support single or multi-unit prostheses for partially or fully edentulous patients. In vitro experiments and finite element analyses can be used to investigate their mechanical performance. Accurate information is needed on the geometry, material properties and friction coefficients of different implant-abutment components, on real loading ...

objective: at present, treatment of edentulous areas with implant-supported prosthesis has greatly increased. the aim of this study was to assess the survival rate of implants with different diameters. methods: this retrospective study was conducted on 239 warfare victims presenting to qazi tabatabaie clinic during 2000-2010. a total of 1,649 implants were placed. the success criteria included ...

Dental implants are a common treatment for the loss of teeth. This paper summarizes current knowledge on implant surfaces, immediate loading versus conventional loading, short implants, sinus lifting, and custom implants using three-dimensional printing. Most of the implant surface modifications showed good osseointegration results. Regarding biomolecular coatings, which have been recently deve...

PURPOSE To investigate the modified protocol for immediate occlusal loading of the zygomatic implants and to report the preliminary results of this modified protocol. MATERIALS AND METHODS Four male patients and 1 female patient with edentulous maxillae were consecutively treated with the zygomatic implants under general anesthesia. All 5 patients were examined by computed tomography and inve...

The introduction of osseointegrated implants in dentistry represents a turning point in dental clinical practice. Thanks to their multiple therapeutic possibilities and the high predictability of success, implant therapy is now regarded as an extremely reliable approach to replace missing teeth. The concept of immediate implant loading has become popular due to less trauma, reduced overall trea...

BACKGROUND Insufficient bone volume often hamper placement of dental implants in the posterior maxilla. PURPOSE The aim of the present clinical study was to evaluate retrospectively the clinical outcome of implant placement in the resorbed posterior maxilla using an osteotome technique without adding any grafting material. MATERIALS AND METHODS Twenty patients with 5 to 9 mm of residual alv...

Background: The treatment plan of prosthetic restorations supported by dental implants requires comprehensive scientific knowledge to deliver prostheses with good prognosis, even before the implant insertion. This review aims analyze main determinants prognosis implant-supported prostheses. Methods: A literature was conducted a PICO (Patient Intervention Comparison Outcomes) question: “For part...

Dental rehabilitation of a completely edentulous geriatric patient has always been a challenge to the clinician, especially in treating those with higher expectations and demands. Treatment duration and the amount of residual alveolar bone available are often important considerations when planning for dental implant-based fixed treatment for these patients. With the introduction of zygomatic im...
