This article describes the dental implant-based rehabilitation of a partially edentulous patient with a unilateral maxillary dento-alveolar defect. A screw-retained prosthesis with a modified design was fabricated on zygomatic and regular dental implants. One section of the implant prosthesis has cemented crowns and the other section is conventional screw-retained. The design of the prosthesis ...

The Brånemark dental implant has undergone progressive development in terms of both the implant body itself and the components connecting the implant to the prosthesis. Many screw and abutment designs have been developed, with various degrees of success. About 15 years ago, CAD (computer-assisted design)-CAM (computer-assisted manufacture) technology was introduced to dentists. More recently CA...

Bone adaptation or integration of an implant is characterized by a series of biological reactions that start with bone turnover at the interface (a process of localized necrosis), followed by rapid repair. The wound healing response is guided by a complex activation of macrophages leading to tissue turnover and new osteoblast differentiation on the implant surface. The complex role of implant s...

This paper presents a case study of applying rapid prototyping in assisting in the design and development of inter-vertebral implants for spine fusions. The major process of design and implant development, its biological and mechanical requirements, the approach for developing a 3D reconstructive vertebral anatomy model, the inter-vertebral implant CAD model, and the integration with a finite e...

BACKGROUND Skin flap failure is a significant, though relatively uncommon complication of cochlear implant surgery. To achieve a good surgical result, a proper plan to locate the prospective implant is required. Thus, a new design of flap was evaluated in this regard. METHODS Two hundred and eleven consecutive children undergoing cochlear implantation in Baqiyatallah Cochlear Implant Center w...

crestal bone loss is a biological complication in implant dentistry. the aim of this study was to compare the effect of progressive and conventional loading on crestal bone height and bone density around single osseointegrated implants in the posterior maxilla by a longitudinal radiographic assessment technique.twenty micro thread implants were placed in 10 patients (two implants per patient). ...

General term of implantation implies insertion of biomaterials of different designs into the tissues. Oral implantation is a surgical insertion of aloplastic materials (metals, alloys, ceramics, polymers, carbons as well as their combinations) into the hard and soft tissues of the upper and lower jaws . The essence of implantology lies in favorable reaction of the organism to the presence of fo...

Primary implant stability is considered to be a critical factor for obtaining successful osseointegration [1]. Studies using Resonance Frequency Analysis (RFA) have demonstrated that initial implant stability is determined by the density of the bone, the surgical technique used, and the design of the implant [2, 3]. While different implant designs have shown similar results of higher stabilitie...

This study investigated the correlation between bone characteristics, design of orthodontic mini-implants, pull-out force, and primary stability. experimental in vitro has examined commercial mini-implants different sizes designs, produced by two manufacturers: Tomas-pin SD (Dentaurum, Ispringen, Germany) Perfect Anchor (Hubit, Seoul, Korea). The total number 40 were tested. There are propertie...

The stability of cementless acetabular cups depends on a close fit between the components and reamed acetabular cavities to promote bone ingrowth. Cup performance and stability are affected by both design and environmental (patient-dependent and surgical) factors. This study used a statistically based metamodel to determine the relative influences of design and environmental factors on acetabul...
