A partial edentulous area was restored with a tooth to implant fixed partial denture and a rigid connection between the two elements. Maintenance recalls were performed over a 19-year period of ob- servation on a yearly basis. Methods. The following parameters were collect- ed during each examination over the entire period of observation: PD around the implant and natural tooth abutment, gingival index, modified gingival index, plaque index, modified plaque index, oc- clusal assessment, marginal bone loss. Radi- ographic assessment of peri-implant bone remod- eling was performed in a retrospective way. The following reference points were assessed on each image: fixture-abutment junction, threads, first contact of the crestal bone with the implant on both mesial and distal side. This made possible, with the known values for implant diameter and length, to make linear measurements of remain- ing peri-implant bone measured from the mesial and distal marginal bone levels and the fixture- abutment junction. The amount of bone change over the baseline to a 19 years follow-up observa- tion time was calculated for both the implant and the natural tooth. Results. Clinical parameters showed healthy values over the entire period of observation with slight iso- lated positive bleeding on probing. Bone remodel- ing values were constant over the entire period with slight higher values around the tooth. Peri-apical ra- diographs did not show any intrusion of the tooth. Conclusions. The present case report showed the complete functionality and stability of a tooth to im- plant rigidly connected FPD over a period of 19 years.
