PURPOSE The aim of the present study was to analyze bone tissue reactions at implants with and without a microthread configuration. MATERIALS AND METHODS In six beagle dogs, one test and two control implants were installed in one side of the mandible. While both implant types had a similar dimension and surface roughness, the test implants were designed with a microthread configuration in the...

PURPOSE This study compares the prognosis (the survival rate and marginal bone loss) of resorbable blasting media (RBM) surface implants and sandblasting with large-grit and acid-etching (SLA) surface implants in the early loading. METHODS This study targeted 123 patients treated by implants installation from January 2008 to March 2010. The loading was initiated in the maxilla within three to...

AIM The aim of this systematic review and meta-analysis was to assess and compare peri-implant marginal bone loss in cement- and screw-retained prostheses. MATERIAL AND METHODS Electronic database and manual searches were undertaken to identify trials, prospective or retrospective studies reporting on radiographic marginal bone loss around dental implants restored with cement- and/or screw-re...

PURPOSE The aim of this study was to evaluate the clinical findings and patient satisfaction on implant overdenture designed with Locator implant attachment or Locator bar attachment in mandibular edentulous patients. MATERIALS AND METHODS Implant survival rate, marginal bone loss, probing depth, peri-implant inflammation, bleeding, plaque, calculus, complications, and satisfaction were evalu...

The benefits and feasibility of platform switching have been discussed in several studies, reporting lesser crestal bone loss in platform-switched implants than in platform-matched implants. Objective. The aim of the present study was to observe the changes in vertical and horizontal marginal bone levels in platform-switched and platform-matched dental implants. Materials and Methods. 51 patien...

Early clinical reports on osseointegration of dental implants have reported success rates of 81% in maxilla and 91% in mandible after 15 years, with marginal bone loss of 1.5 mm in the first year and approximately 0.1 mm annually from there after. This satisfied the success criteria which were published in the years to follow; they were clinical stability, in function without any symptoms and w...

Besides alveolar bone quality, the drilling protocol applied in conjunction with design of an implant are major determinants primary stability. Surgical trauma and compression resulting from insertion may constitute one cause for marginal resorption. Inserting two current bone-level designs (Astra; Straumann; n = 5) bovine ribs, stability, strain development on buccal plate histologic signs dam...

Several studies have shown that surgical detachment of marginal gingiva close to the cervical cementum of molar teeth in a rat mandible is a distinct stimulus for alveolar bone resorption. Recently, we found that P2X4, an ATP-receptor, is significantly up-regulated in marginal gingival cells soon after surgery. We hypothesized that local release of ATP signaling through P2X4 elicits activation ...

BACKGROUND Immediate implant function has become an accepted treatment modality for fixed restorations in totally edentulous mandibles, whereas experience from immediate function in the edentulous maxilla is limited. PURPOSE The purpose of this study was to evaluate a protocol for immediate function (within 3 hours) of four implants (All-on-4, Nobel Biocare AB, Göteborg, Sweden) supporting a ...

Background and objectives. Immediate implant placement can be considered a predictable protocol, even in esthetic areas. The objective of this study was to compare the clinical outcomes and the total costs of immediate and delayed restoration of implants with a specific design placed into fresh extraction sockets after 1 year from the implant placement. Materials and Methods. Blossom implants (...
