The data collection will take place at four different times: in connection with the placement of the prosthetic construction (baseline) and after 1.3 and 5 years. Standard x-ray examinations will be carried out to check the marginal bone level which will take place through individualized x-ray holders that will be produced by impression material (Putty). Registration of pocket depth, bleeding on probing, amount of keratinized mucosa and measurements on x-ray will be done by the same person. Prosthetic complications and possible total implant loss will be registered.
