Orthopedic implant removal is a commonly performed procedure. While implant removal can be associated withimproved symptoms, risks of the surgery are notable. Stripped screws, broken and retained hardware, and morbidityassociated with soft tissue compromise during difficult removal are all common. Familiarity with the instruments iscritical to procedure success. The purpose of...

introduction: a limited number of studies have evaluated factors influencing the retention of fixed prostheses cemented to implant abutments. the aim of this study was to compare the effect of varying degrees of screw access channel obturation on retention of implant-supported cast fixed restorations. materials  & methods: in this experimental study, 40 implant abutments with a diameter of 4.5 ...

objective : the aim of this study was to assess the amount of interdental bone in posterior areas of the mandible for placing orthodontic mini-implants to provide and control anchorage in orthodontic treatment. materials and methods : the amount of interdental bone in areas between the second premolars and first molars, first and second molars on the right and left sides of the mandible were de...

introduction: the use of lasers for treatment has become a common phenomenon in the medical field. currently, numerous laser systems are available for dental use. the use of lasers for periodontal treatment becomes more complicated because the periodontium consists of both hard and soft tissues. methods: related articles were gathered and selected carefully and reviewed. among the many lasers a...

background : since the introduction of silicone based medical devices in to clinical practice, several reports appeared in the medical literature regarding their adverse effects. however, there are few reports of immunologic reactions to these implants. case presentation : a case of systemic reaction to a breast implant inserted for immediate breast reconstruction in a breast cancer patient is ...

distal extension removable partial denture is a prosthesis with lack of distal dental support with a 13-fold difference in resiliency between the mucosa and the periodontal ligament, resulting in leverage during compression forces. it may be potentially destructive to the abutments and the surrounding tissues. the aim of this study was to assess the effect of implant location on stress distribu...

objective: to study the accuracy of spiral tomography in the determination of implant angulation. materials and methods: eighteen gutta-percha filled points on dry mandibles were selected for implant placement. a translucent acrylic template was fabricated for each mandible. after preparing tomographic images (2 mm slice thickness, cranex tome), the ideal axis of the implant was traced. the ang...

objective: to determine the pattern of stability changes as a reflection of early healing around single-stage roughened-surface implants in humans utilizing resonance frequency analysis (rfa). materials and methods: hundred twenty-five patients who demanded dental implants were treated with two different implant (nobel biocare replacetm and strummantm iti) systems. bone type was classified into...
