    Unit of Oral Surgery and Implantology, University-Hospital at Geneva, Department of Surgery, School of Dental Medicine, Geneva, Switzerland.
    Background: Implant stability is commonly related to insertion torque. Recently, it has been suggested that higher insertion torque may lead to greater bone resorption.

    Purpose: The aim of the present randomized clinical study was to evaluate the role of different insertion torque values in terms of implant success, marginal bone loss, and facial soft tissues recession. Read More

    Peri-implant conditions and levels of advanced glycation end products among patients with different glycemic control.
    Clin Implant Dent Relat Res 2018 Jun 19;20(3):345-351. Epub 2018 Jan 19.
    Faculty of Dentistry, Department of Periodontology, Ziauddin University, Karachi, Pakistan.
    Background: A close relationship between poor glycemic control and peri-implant break down has been demonstrated. It is hypothesized that levels of advanced glycation end products (AGEs) in peri-implant sulcular fluid (PISF) are higher with increased glycemic levels in type 2 diabetes mellitus patients.

    Purpose: In the present study, we examined the clinical and radiographic peri-implant parameters and levels of AGEs among different glycemic levels in diabetic patients and assessed whether the levels of AGEs correlate with clinical peri-implant parameters. Read More

    Measurement properties of gingival biotype evaluation methods.

    Department of Prosthodontics and Periodontology, Bauru School of Dentistry, University of São Paulo, Bauru, São Paulo, Brazil.
    Background: There are numerous methods to measure the dimensions of the gingival tissue, but few have compared the effectiveness of one method over another.

    Objective: This study aimed to describe a new method and to estimate the validity of gingival biotype assessment with the aid of computed tomography scanning (CTS).

    Materials And Methods: In each patient different methods of evaluation of the gingival thickness were used: transparency of periodontal probe, transgingival, photography, and a new method of CTS). Read More

    Radiographic analysis of dental implant extensions using bone grafts on dogs.
    Clin Implant Dent Relat Res 2018 Apr 10;20(2):222-228. Epub 2018 Jan 10.
    Electrical Engineering Faculty, Federal University of Uberlandia, Uberlândia, Minas Gerais, Brazil.
    Background: Despite the wide use of dental implants they can bring inconveniences, as the moment one reaches osseointegration, these can no longer be extended. Therefore, if a problem occurs regarding its positioning, the options open are substitution or burial of the implant. With implant substitution, there exists the risk of local bone loss and/or future loss of the new implant. Read More

    Lateral bone augmentation in narrow posterior mandibles, description of a novel approach, and analysis of results.
