Abstract: The invention relates to a mouthpiece for performing a treatment of teeth such as teeth whitening. Accordingly, the mouthpiece may be arranged for cosmetic treatment. The treatment is based on illumination of the teeth of light with a suitable wavelength. The mouthpiece is designed so that light from light sources, e.g. LED's, is sufficiently homogenized so that the light irradiance at the teeth is sufficiently uniform to achieve good treatment results. Furthermore, the mouthpiece is designed so that the irradiance at the teeth is sufficiently high to achieve efficient treatment and so that heating of the teeth is minimized to an acceptable heating.

A temporary abutment cap is configured to be coupled to the upper region of the temporary abutment. The temporary abutment cap has at least one projection configured to mate with the at least one retention groove of the temporary abutment. The temporary abutment cap has a second anti-rotational structure that is configured to slidably engage the first anti-rotational structure of the temporary abutment. The temporary abutment cap is configured to be coupled with a temporary prosthesis such that the temporary prosthesis and the temporary abutment cap are removable from the temporary abutment.
