Background: As dental implants receive masticatory stress, the distribution of stress is very important to peri-implantbone homeostasis and implant survival. In this report, we created a saddle-type implant and analyzed its stability andability to distribute stress to the surrounding bone. Methods: The implants were designed as a saddle-type implant (SI) that wrapped around the alveolar bone, and thesizes of the saddles were 2.5, 3.5, 4.5, and 5.5 mm. The X and Y displacement were compared to clarify the effects ofthe saddle structures. The control group consisted of dental implants without the saddle design (CI). Using finiteelement modeling (FEM), the stress distribution around the dental implants was analyzed. Results: With saddle-type implants, saddles longer than 4.5 mm were more effective for stress distribution than CI. Regarding lateral displacement, a SI of 2.5 mm was effective for stress distribution compared to lateral displacement. ASI that was 5.6 mm in length was more effective for stress distribution than a CI that was 10 mm in length. Conclusions: The saddle-type implant could have a bone-gaining effect. Because it has stress-distributing effects, itmight protect the newly formed bone under the implant.
