Influence of Crown-to-Implant Ratio on Stress Concentration of Fixed Dental Prosthesis in Shortened Dental Arch Concept
Dental implants have been accepted as a successful treatment procedure for partially and totally edentulous jaws. However, bone density and anatomic structures (maxillary sinus etc.) must be considered carefully when the edentulous region is located in the posterior maxilla. Adequate and ideal bone volume for correct positioning of implants can be created in the posterior maxilla by bone augmentation or sinus floor elevation. Fixed Dental Prosthesis However, these surgical procedures are associated with increased rate of complications and healing time, especially in older patients. Moreover, surgical procedures may not be the best option for every patient, and toothor implant-supported cantilever fixed dental prostheses (FDP) may be an alternative when augmentation procedures are not possible. When premolar or molar teeth are missing in the posterior maxilla, the first premolar site is suggested as the ideal location for implant insertion because of sinus pneumatizati...
