Objectives Data regarding tooth‐ and implant‐supported maxillary removable partial dentures (TIRPDs) are scarce. The objective of this research was to perform a retrospective evaluation of the clinical long‐term outcome of maxillary TIRPDs rigidly retained via telescopic crowns in patients undergoing supportive post‐implant therapy (SIT). Material and Methods The inclusion criteria were met by 26 patients restored with maxillary TIRPDs between 1997 and 2011 in a private practice. Primary crowns (Marburg double crowns, MDC s) on teeth were cemented, whereas those on implants were screw‐retained. Using patient records and data from a cross‐sectional clinical examination in 2013, the survival rates of the teeth, implants and prostheses, together with the biological and technical complications, were analyzed. Results After 6.12 ± 3.80 (range: 2−16) years of loading, 23 non‐smoking patients with 23 dentures supported by 60 implants and 66 teeth were available for assessment. Nine teeth (survival rate: 86.36%) were lost, whereas 1 implant (survival rate: 98.36%) failed because of peri‐implantitis. Although 30 implants (50%) in 16 patients (69.57%) showed bleeding on probing (BOP+), no further peri‐implantitis was observed. The mean peri‐implant probing depth (PPD) was 3.68 ± 0.71 mm. All dentures were functional and required technical maintenance efforts amounting to 0.128 treatments per patient per year (T/P/Y). Conclusions Within the limitations of this study, we conclude that TIRPDs retained via MDC s may represent a viable treatment option for patients with residual maxillary teeth.
