Though oral rehabilitation with dental implants is quite a predictable and well-documented technique, long-term survival may be hampered by various factors. The biomechanical factor crown height space (CHS) has been an object of research frequently. A situation that often occurs in areas of tooth loss is an increase in the interocclusal space because of bone resorption, requiring lengthy crowns and thus a disproportionate crown implant ratio (CIR), that is, with implants shorter than crowns. A reduced CHS has biomechanical issues related to the strength of implant material and/or prosthetic components, flexibility of the material, and retention requirement of the restoration. In fixed restorations, the movement of the material may increase porcelain fracture, screw loosening, and/or uncemented restorations. The current literature review is a discussion on the biomechanical consequences of decreased crown height space.
