One-Year Multicenter Randomised Controlled Trial Comparing OT Equator® and Locator Attachments to Retain an Early Loaded Implant Overdenture on Two Implants.

This investigation aimed to compare the effectiveness of the OT Equator® (Rhein, Bologna, Italy) and the Locator attachment systems used to retain early loaded implant-retained overdentures. This study was designed as a multicenter randomised controlled trial of parallel groups. After implant placement, the patients were randomised to receive OT Equator® attachments in the test group or Locator attachments in the control group.

1-Year Evaluation of OT Bridge Abutments for Immediately Loaded Maxillary Fixed Restorations: A Multicenter Study.

Objective:  Preliminary data on survival and success rates of immediately loaded, maxillary, screw-retained, implant-supported, fixed restorations delivered on narrow and low-profile OT Equator abutments (OT Bridge, Rhein'83) were evaluated.

Materials And Methods:  This retrospective study evaluated data collected from patients rehabilitated with OT Bridge prosthetic concept between November 2017 and February 2019 in six different centers. Outcome measures were implant and prosthetic survival rates, biological and technical complications, marginal bone loss (MBL), oral health impact profile (OHIP), bleeding on probing, and plaque index.

Multicenter Retrospective Analysis of Implant Overdentures Delivered with Different Design and Attachment Systems: Results Between One and 17 Years of Follow-Up.

Purpose: To analyze implant and prosthetic survival rates, complications, patient satisfaction, and biological parameters of patients rehabilitated with implant overdentures (IOV) on splinted and nonsplinted implants and different attachment systems, in function for one to 17 years.

Methods: This retrospective study evaluated data collected from patients rehabilitated with implant overdentures between January 2001 and December 2016 in nine different centers. Outcome measures were implant and prosthetic success rates, mechanical complications, marginal bone loss (MBL), oral health impact profile (OHIP), bleeding on probing, and plaque index.

Aperius interspinous implant versus open surgical decompression in lumbar spinal stenosis.

Background Context: Few studies have analyzed the results of an interspinous distraction device in patients with lumbar spinal stenosis. It is still unknown whether the outcomes of an interspinous implant are related to the severity of stenosis.

Purpose: To determine the success rate of the Aperius implant and open decompression with the aim of defining better the indications for the two modalities of treatment.

Graft vascularization is a critical rate-limiting step in skeletal stem cell-mediated posterolateral spinal fusion.

The ability of skeletal stem cells (SSCs) to direct spinal fusion (SF) upon transplantation in conjunction with osteoconductive biomaterials was investigated in a rabbit model. When tested in a mouse heterotopic transplantation assay, rabbit SSCs and Pro-Osteon 500R was osteoconductive and supported osteogenesis. When used in a SF model, the same constructs induced bone formation in periapophyseal regions (PARs).
