Implant rehabilitation of a posterior maxilla with 4-mm long implants splinted to a 10-mm long implant in a patient with osteopenia taking antiresorptive drugs: A 5-year follow-up case report

Katja Povšič et al. Clin Case Rep. .

Abstract

The report describes the rehabilitation of a maxillary arch with limited bone volume in a 67-year-old female taking antiresorptives due to osteopenia. One 10-mm and two extra-short 4-mm implants were inserted, and implant-supported splinted crowns were fabricated. The 5-year follow-up showed stable bone levels, despite poor initial stability (ISQ: 14-51).

Keywords: alveolar bone loss; dental implants; maxilla; osteopenia; short dental implants; survival rate.
