OBJECTIVES The purpose of this study is to clinically and radiographically evaluate survival and success rate of multiple zirconia dental implants positioned in each patient during a follow-up period of at least 12 months up to 48 months. STUDY DESIGN Eight patients were treated for multiple edentulism with 29 zirconia dental implants. All implants received immediate temporary restorations an...

background and aims. all-on-four technique involves the use of tilted implants to allow for shorter cantilevers. this finite element analysis aimed at investigating the amount and distribution of stress in maxillary bone surrounding the implants with all-on-four vs. frequently used method with six implants technique using different numbers and inclination angles. materials and methods. a 3d ede...

objective: successful bonding of a dental implant to bone, which was referred to as osseointegration by branemark has been well documented. however, long-term prognosis of an implant depends on adequate maintenance and long-term care. an effective maintenance program is required to preserve the health of peri-implant tissues. several techniques have been suggested for this purpose but it is not...

objectives: the aim of this study was to compare the accuracy of dental implant impressions obtained by a combination of different impression techniques and viscosities of polyvinyl siloxane (pvs). materials and methods: four parallel fixtures were placed between mental foramina in a master model of lower dental arch. three different viscosities (putty/light body, medium body/light body, and mo...

OBJECTIVE Predoctoral dental implant education is included in dental school teaching curricula in most of the developed and some developing countries; however, it was not introduced into undergraduate curriculum of some countries and Iranian dental schools. Our purpose was to investigate the status of the predoctoral dental implant education of dental schools in the world. MATERIALS AND METHO...

Implant retained mandibular overdentures are a successful treatment option for the edentulous patients with long-term predictable outcomes, using conventional loading protocols. In recent year modified loading protocols such as immediate loading have been introduced. These loading protocols showed good clinical results with favorable peri-implant tissue response after implant insertion. However...

The purpose of this review is to explore the concept of immediate loading as it pertains to dental implants and the indications for clinical practice. The definition of immediate loading will be considered together with a review of the relevant literature in an attempt to provide evidence-based guidelines for successful implementation into practice. A search of electronic databases including Me...

Placement of endosseous implants has made it possible to perform restorations in patients who are fully or partially edentulous (1, 2, 20, 21). Original protocols required the placement of implants into healed edentulous ridges. In 1989, Lazzara (44) placed implants at the time of tooth extraction. Immediate implants were augmented with barrier membranes to preserve ridge width and height and t...

Although initial considerations in implant dentistry have claimed that the process of osseointegration requires on average an undisturbed healing of three months in the mandible and six months in the maxilla 1-3, an increasing interest has been noticed with regard to early and immediate loading of implants to expedite the restorative outcome. Donath et al. reported that load exerted at the impl...
