Educator informed practice within a triadic preceptorship model.

Preceptorships have long been a subject of scholarship with proven effectiveness in preparing nursing students to transition into beginning graduate nurses. Nursing research has predominantly focused on the dyadic preceptor-student relationship. The triadic pedagogical relationship between educator-student-preceptor has garnered less attention and inquiry. Nurse educators' experience in preceptorships is under reported. Through a process of scholarly inquiry, nurse educators from one western Canada School of Nursing documented their experiences and professional judgment in facilitating preceptorships over one semester. In the context of the anticipated exodus of nursing experts in the midst of rapidly changing healthcare delivery, this paper recommends a reemphasis on preceptorships as a triadic pedagogical relationship. Educator informed practices that foster triadic relationships in preceptorships include attending to distant relationships, being mindful of the influence of continuity, recognizing a preceptor's proficiency, responding to rapidly changing and complex environments, facilitating common understanding through communication, and integrating practice and education performance expectations.

Factors affecting survival and usefulness of implants placed in vascularized free composite grafts used in post-head and neck cancer reconstruction.

BACKGROUND: Bone-containing vascularized grafts have been used successfully to reconstruct post-cancer surgical defects. Dental implants can be placed in these bone-containing grafts to allow implant-supported prosthodontic reconstruction of these patients. PURPOSE: The aim of this study was to evaluate the survival of dental implants used in the rehabilitation of subjects treated with bone-containing vascularized grafts to compare usability of implants placed at the time of reconstruction and after healing. MATERIALS AND METHODS: A cross-sectional study was undertaken to examine survival rates of implants placed in vascularized bone-containing grafts either immediately at the time of surgical reconstruction or after 3 months healing. Other factors such as graft type, whether radiation therapy was given, and implant type were recorded. RESULTS: A total of 41 patients had 145 implants placed in 47 vascularized bone-containing flaps. Increased failure rate of implants was seen in immediately placed implants. There was also a significant increase in the number of osseointegrated implants that were prosthodontically unusable or sub-optimally placed in the immediate placement group. Radiation therapy was associated with a significant increase in failure rate. Modern implant surfaces appeared to perform better than machined/turned surfaces. Graft donor site did not influence implant survival. CONCLUSION: This study demonstrated the difficulties encountered with immediate placement of dental implants at the time of post-cancer reconstructive surgery.
