PURPOSE The purposes of the present study were: to compare the resonance frequency analysis (RFA) values of implant placed in either ramus or calvaria block grafts; and to determine if implant diameter influences RFA implant stability quotient (ISQ) value. MATERIAL AND METHODS This was a retrospective study that included 16 consecutives healthy patients treated with autogenous onlay block gra...

Purpose: Implant length, implant surface area, and crown-to-root (c/r) ratio and their relationship to crestal bone levels were analyzed in 2 groups of partially edentulous patients treated with sintered porous-surfaced dental implants. Materials and Methods: One hundred ninety-nine implants were used to restore 74 partially edentulous patients with fixed prostheses. Implants were categorized a...

Introduction. In order to minimize the required time to regain esthetic and function, immediately loaded implants were suggested. The aim of this study was to comparatively evaluate the Nisastan and XIve implants using biomechanical and histomorphometric tests. Materials and Methods. In this experimental study, 6 Nisastan one-piece immediately loaded screw type implant (OPILS) and 6 Xive implan...

INTRODUCTION Various anchorage techniques have been designed for canine retraction. Intraoral techniques have not always been successful, and now implants are widely used for this purpose. A new type of titanium microimplant, with a small diameter and a button-like head, was shown to be an effective source of anchorage for distal movement of the canines. The purposes of this study were to measu...

objective: to assess the stability changes as a reflection of early healing around roughened- surface implants in human by resonance frequency analysis (rfa). materials and methods: one hundred and fifty one iti sla implants were placed in either maxilla or mandible of 68 patients. bone type was classified into 4 groups according to lekholm and zarb index. rfa was used for direct implant stabil...

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 Replace™ and Strumman™ ITI) systems. Bone type was classified into f...

Background: Narrow-diameter implants are planned for specific clinical conditions as locator between adjacent teeth with a narrow bone width or only area in between. They especially advantageous when restoring like lateral maxillary and mandibular incisors first premolars.
 Methods: In the period 2018 2019, 21 patients were rehabilitated implant treatment. A total of 32 placed (The Strauma...

PURPOSE The aim of this study was to analyze the short-term predictability and reliability of Astra Tech implants according to the demographical distribution of patients and condition of implant sites and location of implants. METHODS Among patients treated with Astra Tech implant (Astra Tech AB) in the Department of Periodontology at the Dental Hospital of Yonsei University of College of Den...

PURPOSE To correlate soft tissue thickness and peri-implant bone remodeling of platform-switching implants. MATERIALS AND METHODS This comparative prospective trial evaluated, for up to 3 years after implant loading, the influence of soft tissue thickness on changes in peri-implant marginal hard tissue levels. Any patient who was partially edentate in the mandible and required at least two ad...

PURPOSE Several long-term clinical studies have shown a mean marginal bone loss around dental implants of 1.5 to 2 mm in the first year after prosthetic restoration. Currently, concepts to avoid bone remodeling around dental implants have been developed. The use of prosthetic abutments with reduced width in relation to the implant diameter (platform switching) seems to have the greatest potenti...
