Achieving the stability of bone tissue in field dental implants is still most urgent and completely unsolved problem implantological practice. Modern ideas about biological principles structure functioning tissues periimplant zone are one significant factors ensuring crestal tissue. The soft-tissue component that forms basis complex at implant-suprastructure interface plays a key role protectin...

PURPOSE The aim of this study was to histologically evaluate the crestal bone response to loaded and unloaded implants in beagle dogs. MATERIALS AND METHODS Sand-blasted and acid-etched implants (Bone System, Milano, Italy) were placed in the mandible of six beagle dogs. The two premolars and the first molars had been extracted 3 months previously. Each dog received 12 implants in the mandibl...

Methods: Light-hardened poly-methyl-methacrylate, poly-hydroxyl-ethyl-methacrylate, and calcium hydroxide plus polyanhydride (PPCH+PA) composite graft), PPCH graft alone, PA graft alone, were compared to each other and to a no graft control group. All mandibular premolar teeth were extracted; a total of 48 implants were placed into sockets of the mesial roots in three minipigs. Crestal areas an...

PURPOSE The purpose of this study was to evaluate the efficacy of bone ring augmentation technique for three-dimensional augmentation of severely defective sockets along with placement of immediate dental implants. MATERIALS AND METHODS A clinical study was conducted on 14 patients with 15 defective sockets requiring extractions and immediate implant placement. Following extraction, bone ring...

Porphyromonas gingivalis and Treponema denticola are periodontal pathogens that express virulence factors associated with the pathogenesis of periodontitis. In this paper we tested the hypothesis that P. gingivalis and T. denticola are synergistic in terms of virulence; using a model of mixed microbial infection in rats. Groups of rats were orally infected with either P. gingivalis or T. dentic...

ABSTRACT Purpose: The aim of the study was to evaluate crestal bone height changes around laser grooved implants with mandibular overdenture. Materials and Methods: sample comprised 10 completely edentulous male patients age range between 40-60 years. In each patient, two were placed in interforaminal area. Implants exposed after three months healing, ball abutments used retain dentures. Cresta...

OBJECTIVE To evaluate marginal bone loss over 3 years around immediate microthreaded implants placed in the maxillary anterior/esthetic zone and immediately restored with single crowns. MATERIAL AND METHODS Seventy-one implants (with microthreads up to the platform--rough surface body and neck, internal connection and platform switching) were placed in fresh extraction sockets in the maxillar...

PURPOSE The purpose of this report is to describe the crestal bone level (CBL) around implants of various designs, describe the peri-implant soft tissue condition, and evaluate the relationship between the two over time. MATERIALS AND METHODS This retrospective cohort study reports on 2,060 patients with 4,591 implants evaluated after 3 months; 1, 3, 5, and 7 years; and up to 10 years. Periap...

Last year, the American Association of Orthodontists (AAO) Board of Trustees appointed President Lee Graber and me to a joint task force along with the current president of the American Academy of Periodontology and another practicing periodontist. Our charge was to determine how orthodontists can avoid being sued for periodontal problems that arise during orthodontic treatment. Is this a real ...
