Purpose: To evaluate the efficacy of immediate loading versus early loading at 6 weeks of bar-retained mandibular overdentures supported by two implants placed with a flapless technique. Materials and methods: Sixty patients were randomised: 30 to the immediately loaded group and 30 to the early loaded group. To be immediately loaded, implants had to be inserted with a minimum torque > 48 Ncm. ...

Statement of problem: There is little information about the maintenance requirements of implant restorations. Purpose: To compare the prosthodontic maintenance requirements of screw-retained implant prosthesis versus that of telescopic overdentures after an observation period of 18 months. Materials and methods: 26 completely edentulous patients were enrolled in the study. Patients were divided...

BACKGROUND The purpose of this clinical study was to evaluate the complications associated with the different attachments used in implant-supported overdentures, including prosthetic problems and implant failures. A comparison of ball, bar and Locator (Zest Anchors, Inc, homepage, Escondido, CA, USA) attachments, in completely edentulous patients with two, three or four implants, was conducted....

AIM An analysis is made of the clinical and radiological behavior of 80 implants with a new surface subjected to etching with a sulfuric and hydrofluoric acid solution followed by thermal treatment, and subjected to immediate loading in patients with lower overdentures. STUDY DESIGN A prospective observational study was made of 20 patients with lower overdentures supported by four implants me...
