Is the implant-retained overdenture a solution to improve the patient quality of life?

Design The research was a retrospective cohort study evaluating a study which performed routine control sessions to assess bone loss around the dental implant over five years and 12 and 24 months, after their prosthetic restorations.Aim The study aimed to evaluate patients' dental implant marginal bone loss after oral rehabilitation with bar and locator retainers and their possible complications.Methods A study of 114 patients who had received 283 dental implants from 2013-2018 was conducted.

Direct custom implant impression copings for the preservation of the pontic receptor site architecture.

The direct custom implant impression coping technique is designed to record the periimplant gingiva and pontic receptor site after the tissues have been shaped with a provisional restoration. The technique prevents inaccurate recording of the gingival architecture by using a dual polymerizing composite resin placed into the sulcus and pontic receptor sites and adapted to the open tray implant impression copings. This technique may improve soft tissue accuracy between the clinical condition and the laboratory cast.

How do smoking, diabetes, and periodontitis affect outcomes of implant treatment?

Purpose: Implant therapy is highly predictable and successful. However, certain risk factors can predispose individuals to lower rates of success. The purpose of this systematic review was to evaluate the available literature to assess whether smoking, diabetes, and periodontitis have an adverse affect on the outcomes of implants placed in patients with these conditions.

Platelet-derived growth factor stimulates bone fill and rate of attachment level gain: results of a large multicenter randomized controlled trial.

Background: Growth factors are generally accepted to be essential mediators of tissue repair via well-established mechanisms of action that include stimulatory effects on angiogenesis and cellular proliferation, ingrowth, differentiation, and matrix biosynthesis. The aim of this study was to evaluate in a large-scale, prospective, blinded, and randomized controlled clinical trial the safety and effectiveness of purified recombinant human platelet-derived growth factor (rhPDGF-BB) mixed with a synthetic beta-tricalcium phosphate (beta-TCP) matrix for the treatment of advanced periodontal osseous defects at 6 months of healing.

Methods: Eleven clinical centers enrolled 180 subjects, each requiring surgical treatment of a 4 mm or greater intrabony periodontal defect and meeting all inclusion and exclusion criteria.
