The present pilot study could not confirm an immediate rise in bite force after implant rehabilitation. Instead, improvements were mainly noted up to 3 months after surgery and rehabilitation. Furthermore, it became evident that despite gradually improved bite force in all patients, masticatory efficiency and food hardness perception did not necessarily follow the same trend. The present findings may be used to adapt oral function after implant rehabilitation by studying the combined outcome of four tests (occlusal contact, maximum bite force, masticatory efficiency, and food hardness perception). Studies with a longer follow-up time and larger sample sizes are needed to verify the present results.
