PURPOSE Prevention of peri-implant bone loss is essential for achieving long-term implant success, but few studies have evaluated the impact of placement depth on long-term bone loss. The aim of this retrospective study was to evaluate outcomes for platform-shifted implants placed at different depths relative to the bone crest. MATERIALS AND METHODS The mesial and distal shoulders of 228 dela...
PURPOSE Facial crestal bone level and dimension determine function and esthetics of dentition and dental implants. We have previously demonstrated that ultrasound can identify bony and soft tissue structures in the oral cavity. The aim of this study is to evaluate the accuracy of using ultrasound to measure facial crestal bone level and thickness. MATERIALS AND METHODS A commercially availabl...
Aim: The purpose of the study was to evaluate the changes in peri-implant bone quality, crestal bone level and the implant stability (periotest) for mandibular implant retained overdentures with ball attachments using delayed and immediate loading protocols. Materials and methods: Two Alpha-Bio dental implants were placed in the anterior part of the mandible in ten completely edentulous patient...
BACKGROUND Experimental studies demonstrated that peri-implant crestal hard and soft tissues are significantly influenced in their apico-coronal position by the rough/smooth implant border as well as the microgap/ interface between implant and abutment/restoration. The aim of this study was to evaluate radiographically the crestal bone level changes around two types of implants, one with a 2.8 ...
امروزه ، استراتژی ها و روشهای مختلفی توسط مترجمان در زمینه ترجمه متون به کار گرفته می شود. یکی از این روشهای رایج، استفاده از شیفت ها است. مطالعه ی پیش رو کاربرد استراتژی شیفت ها در ترجمه بروشورهای تبلیغاتی مربوط به محصولات مراقبت شخصی از زبان انگلیسی به فارسی را بر اساس مدل کتفورد (1965) مورد بررسی قرار داده است. هدف این مطالعه بررسی میزان استفاده از این استراتژی از طریق مقایسه متون زبان مبدا ...
relevant studies was conducted using electronic The long-term success of an implant depends upon search of the Medline/ Pub Med, Google scholar and integration between implants, hard and soft tissues. related articles. The search words include platform Marginal bone loss around implant may pose a threat switching, biologic width, peri-implant soft tissue, to a long-term survival. Concept of pla...
_Since its introduction, sinus floor augmentation has generated great interest in the international scientific community and been subject to many changes in procedure. The first documented maxillary sinus augmentations using bone grafts date back to the work of Philip J. Boyne in the 1960s.1 An access osteotomy to elevate the sinus membrane can be performed by a vestibular or a crestal approach...
Interimplant papillae are critical to achieving esthetic implant-supported restorations in the maxillary esthetic zone. Stable papillary anatomy, however, depends upon a stable volume of underlying crestal bone for support. Multiple studies have documented a critical interimplant distance of 3 mm, under which crestal bone resorption occurs. The current preclinical proof-of-principle canine stud...
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). ...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
