BACKGROUND AND OBJECTIVE In 2010, the Lithuanian Association of Arhtroplasty was established and on January 1, 2011, initiated a national study of all reoperations after total knee (TKR) and total hip replacement (THR) in Lithuania. The aim of the study was to investigate the revision rates after TKR and THR at two years follow-up. MATERIALS AND METHODS Lithuanian patients undergoing primary ...

Numerous investigations are being carried out to increase the longevity of prosthetic restorations on implants. 2–7 In earlier investigations, only implant losses and thus the losses of crowns were rated as failures. 3, 4 Clinical research activities in implant dentistry have mainly focused on implant survival, and the incidence of biologic and technical complications has been addressed only to...

OBJECTIVE To compare a four- and six-implant maxillary overdenture after an observation period of 5 years. MATERIAL AND METHODS Fifty subjects with functional problems concerning their maxillary denture, who had ample bone volume in the anterior region to place four or six implants, were included and randomly assigned to either group. Implant and overdenture survival, clinical performance, ma...

The concept of a high-performance total knee replacement has gained prominence because of continued technological improvements by implant manufacturers and the changing expectations of an increasingly younger, more active patient population. Improvements in surgical technique, instrumentation, implant design, biomaterials, and implant fixation have occurred in recent years. The literature is in...

BACKGROUND Osseointegrated implants have been documented as efficacious, however, their placement may be contraindicated in some patients due to insufficient bone volume. Techniques such as guided bone regeneration (GBR), immediate implantation, and distraction osteogenesis (DO) have been utilized as ridge enhancement therapies. RATIONALE This systematic review evaluates dental implant surviv...

Background: The projected increase in revision shoulder arthroplasty has increased interest in the outcomes of theseprocedures. Glenoid component removal and conversion to a hemiarthroplasty (HA) is an option for aseptic glenoidloosening after anatomic total shoulder arthroplasty (aTSA).Methods: We identified patients who had undergone revision shoulder arthroplasty over a 15-...

BACKGROUND Until now, sinus floor elevation represents the gold standard procedure in the atrophic maxilla in order to facilitate dental implant insertion. Although the procedure remains highly predictive, the perforation of the Schneiderian membrane might compromise the stability of the augmented bone and implant success due to chronic sinus infection. The aim of this retrospective cohort stud...

PURPOSE It was the aim of the present study to clinically evaluate the success of osteotome-mediated sinus floor elevation (OMSFE) using autogenous and xenogenic bone and a variety of screw-type implants. MATERIALS AND METHODS From August 1995 to February 2003, 276 OMSFE procedures with simultaneous implant placement were completed in 167 patients. RESULTS The mean residual bone height (RBH...

The purpose of this study was to determine implant survival rates by means of life table analyses for a cohort of patients not part of a prospective efficacy trial and treated by practitioners at varying experience levels. Prognostic variables associated with implant failure were identified by means of proportional hazards models and advanced statistical methods that account for patient effects...

The aim of this study was to assess the survival rate of titanium implants placed in irradiated jaws. MEDLINE, EMBASE, and CENTRAL were searched for studies assessing implants that had been placed in nongrafted sites of irradiated patients. Random effects meta-analyses assessed implant loss in irradiated versus nonirradiated patients and in irradiated patients treated with hyperbaric oxygen (HB...
