Interval between injury and lingual nerve repair as a prognostic factor for success using type I collagen conduit.

Purpose: The purpose of the present study was to investigate the role of a type I collagen nerve conduit in the repair of lingual nerve injuries compared with those lingual nerve repairs performed without a collagen membrane and to identify the prognostic factors for functional sensory recovery (FSR).

Materials And Methods: This was a retrospective cohort study evaluating a sample derived from the population of patients who had undergone lingual nerve microsurgery from March 17, 2000, to February 23, 2010 by the same surgeon (V.B.

Immediate loading of splinted locking-taper implants: 1-year survival estimates and risk factors for failure.

Purpose: The purpose of this study was to estimate the 1-year survival rate of immediate vertical-load splinted locking-taper implants and to identify risk factors for implant failure.

Materials And Methods: To address the research aim, the investigators implemented a retrospective cohort study design and enrolled a sample derived from the population of patients who had received immediate vertical-load splinted implants (Bicon, Boston, MA). The predictor variables were the sets of exposures associated with implant failure and classified as demographic, health status, anatomic, implant specific, prosthetic, and surgical.

Changes in crestal bone levels for immediately loaded implants.

Purpose: The authors' objective was to measure crestal bone level change in subjects with immediately loaded implants and to identify risk factors associated with changes in bone level.

Materials And Methods: A retrospective cohort study design was used. The sample comprised subjects who had had endosseous implants placed and immediately loaded between July 2001 and July 2003.
