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....

The use of dental implants in replacing missing teeth is an integral part of restorative dental treatment. Use of conventional complete dentures is associated with several problems such as lack of denture stability, support and retention. However, when mandibular complete dentures were used with two or more implants, an improvement in the patients' psychological and social well-being could be s...

PURPOSE The purpose of this study was to examine the abutment screw stability of screw- and cement-retained implant-supported dental prosthesis (SCP) after simulated cement washout as well as the stability of SCP cements after complete loosening of abutment screws. MATERIALS AND METHODS Thirty-six titanium CAD/CAM-made implant prostheses were fabricated on two implants placed in the resin mod...

The peculiar characteristic of an implant-supported prosthesis is the fact that its fixation is given by the connection of an alloplastic material (the implant) to a living tissue (the bone). This fixation has been defined as rigid and clinically asymptomatic and must be maintained during functional loading (Albrektsson & Zarb, 1993). Under load, bone tissue will undergo a remodeling process, w...

PURPOSE Rehabilitation of the edentulous mandible by implant-supported prosthesis is a successful and satisfying treatment as suggested by many clinical trials. However, the minimum number of implants required for this restoration is debatable. Single implant retained overdenture (SIROD) has gained popularity as a simple protocol. The purpose of this review is to systematically analyze the lite...

The objective of this study was to assess the ability of the University of Illinois at Chicago College of Dentistry (UIC-COD) predoctoral students to provide single tooth implant (STI) prostheses in the maxillary esthetic zone. The patient's esthetic satisfaction and the correlation between prosthodontists' and patients' perspectives were examined. Twenty-seven patients were recruited for recal...

OBJECTIVES The purpose of the present study was to evaluate the long-term effect of the microthread on the maintenance of marginal bone level. MATERIAL AND METHODS Seventeen patients were selected and two types of Astra Tech implants were installed, with the Microthread on the coronal portion of the fixture [Astra Tech Single Tooth Implant (ST)] or without the Microthread [Astra Tech TiOblast...

In a multicenter clinical trial treatment, the effects of overdentures on different implant systems in patients with severely resorbed mandibles were compared 1 year after the insertion of new dentures. The implant systems used were the transmandibular implant (TMI), the IMZ (IMZ), and the Brånemark system (BRA). Treatment was randomly assigned to 88 patients according to a balanced allocation ...

A successful esthetic outcome for implant-supported dentures depends on the careful manipulation of peri-implant tissue as well as the precise placement of the implant. In addition, careful surgical and prosthetic planning is essential for esthetically important areas, especially in partially edentulous cases. This study describes a clinical case that presented absent maxillary central incisors...

Background: Narrow-diameter implants are planned for specific clinical conditions as locator between adjacent teeth with a narrow bone width or only area in between. They especially advantageous when restoring like lateral maxillary and mandibular incisors first premolars.
 Methods: In the period 2018 2019, 21 patients were rehabilitated implant treatment. A total of 32 placed (The Strauma...
