When performing dental implant treatment, fixed ones are better. Fixed ones are not easy to take down, not easy to loosen, and have better retention. If you choose a movable dental implant, there is a risk of food embedding, leading to loosening and loss of the implant, as well as instability of the denture, leading to uncomfortable chewing and thus loosening of the local teeth. Therefore, it is advisable to choose fixed dental implants, which can match your teeth as a whole and effectively prevent loosening or embedding of food and local pressure when eating. On balance, it is better to have fixed dental implants, which are more comfortable and consistent with your own teeth.
