PROGRAM DESCRIPTION:
This webinar will present a review of the literature regarding the use of cement- and screw-retention for single and multipleunit implant restorations. Clinical reports regarding prosthetic and biologic complications associated with these types of restorations will be reviewed including incidences of screw loosening, screw fracture, periimplantitis, occlusion, and crestal bone loss. The benefits and limitations of screw-retained, single- and multiple-unit implant restorations will be illustrated, along with techniques to assure optimal fit between abutments and implant restorative platforms. Screw mechanics are extremely important for long-term success of screw-retained restorations. Preload and torque will also be addressed. Guidelines will be presented for clinicians to use in determining when screw-retained restorations would be the treatment of choice.

PROGRAM OBJECTIVES:
At the end of the program, the participant should be able to:

• Identify the benefits and limitations of screw-retained implant restorations in partially edentulous patients.
  
• Diagnose, treatment plan, and treat patients with screw-retained implant restorations.
  
• Identify the potential complications associated with using screw-retained implant restorations regarding fit, reproducibility, maintenance, and follow up.
  
• Use clinical torque controllers and apply the appropriated torque to abutment and retaining screws.
