A BSTRACT Background: The result of increased occlusal stresses might be fractures in the teeth. It is still unclear how possible risk factors may affect the occurrence of tooth cracks after dental implants with prostheses in nonendodontically restored teeth. Aim: To evaluate the correlation of dental implants with prostheses as a risk factor for the development of cracks in teeth restored nonendodontically. Materials and Methods: Records of 414 patients with 570 teeth who underwent tooth restoration nonendodontically were obtained. The data was obtained regarding the number of implants with prostheses placed before the diagnosis of cracks in nonendodontically treated teeth, the time interval between placement of dental implants, and appearance of cracks in teeth, location of dental implants with respect to cracked tooth. Results: Cracks in tooth was observed in 160 teeth out of 570 teeth evaluated (28.07%) and 144 patients out of 414 patients (34.78%). It was observed that out of 160 teeth with cracks, 66 teeth (41.25%) had cracks after placement of dental implants with prosthesis. Conclusion: Placement of a dental implant with a prosthesis can be a risk factor for appearing cracks in teeth treated nonendodontically.
