Implant-supported restorations are a well-recognized esthetic and functional solution for partially edentulous patients (1,2). In the interim phase of treatment, temporary restorations are required to restore gingival health (2,3), while providing esthetic and functional benefits to the patient (1). Despite these advantages, the use of temporaries present a challenging situation (4). With high potential for clinical failure (2,5,6) and a demand for optimal esthetics (7), considerable scientific interest has been focused on refining the components and processes for predictable implant temporaries (8).

Failure of implant-supported restorations may be directly related to the component design of implant temporaries (9). Cho and colleagues (10) reported that many temporary prostheses applied external stressors that initiated soft-tissue inflammation and inhibited osseointegration. Poorly fitted removable partial dentures can induce undesired forces and resultant stresses in the healing cap and/or implant body (11). These undesired stresses can eventually lead to failure of the implant-supported restorations (12). Therefore, further research focused on temporary abutment designs that minimize these forces is required.

A novel abutment and process for temporization (U.S. Patent No. 12/668832) has been developed (Research Driven, Ontario, Canada) that addresses the functional, aesthetic, and financial requirements of temporary prosthesis and may be considered as an alternative option (13).
