Combination of a Hydraulic Device and Nanohydroxylapatite Paste for Minimally Invasive Transcrestal Sinus Floor Elevation: Procedure and 4-Year Results.

Purpose: The objectives of this retrospective study were to describe a transcrestal sinus floor elevation technique combining the use of a hydraulic device and a nanohydroxylapatite paste and to report on 4-year clinical and radiographic outcomes.

Materials And Methods: The sinus floor elevation procedure used a specially designed drill (SinusJet) to start sinus membrane unsticking and a nanohydroxylapatite paste (Ostim) for further sinus membrane elevation and bone augmentation. It was performed as a one-step procedure with immediate implant placement or a two-step procedure with delayed implant placement 9 months later.

Implantoplasty Versus Glycine Air Abrasion for the Surgical Treatment of Peri-implantitis: A Randomized Clinical Trial.

Purpose: Numerous approaches have been proposed for the treatment of peri-implantitis, but to date, none has been identified as the most effective. This study compared the efficacy of implantoplasty and glycine air polishing for the surgical treatment of peri-implantitis.

Materials And Methods: This prospective, randomized, parallel-group trial included 31 patients presenting with 42 implants with peri-implantitis.

Treatment of mandibular Class II furcations using bovine-derived bone xenograft with or without a collagen membrane: a randomized controlled trial.

Objectives: This randomized clinical trial aimed to compare the effects of a bovine-derived xenograft with (control group, CG) or without (test group, TG) a collagen membrane for the treatment of mandibular Class II furcations.

Method And Materials: Nineteen patients presenting 32 furcations were included and randomly assigned to CG (n = 16) or TG (n = 16). At the 6-month follow-up (M6), 29 furcations were reevaluated.

Oral Microbes, Biofilms and Their Role in Periodontal and Peri-Implant Diseases.

Despite many discoveries over the past 20 years regarding the etio-pathogenesis of periodontal and peri-implant diseases, as well as significant advances in our understanding of microbial biofilms, the incidence of these pathologies still continues to rise. This review presents a general overview of the main protagonists and phenomena involved in oral health and disease. A special emphasis on the role of certain keystone pathogens in periodontitis and peri-implantitis is underlined.
