STEP 8: FINAL PROSTHESIS reinforced to maintain good oral hygiene. This case has a follow-up of 3
The temporary prosthesis was scanned intraorally in order to replicate the years, and the patient is happy with the functioning and esthetics of the
design in the final prosthesis and make necessary changes according to the prosthesis over the implants (Figure 22). Prescription of a night guard after
patient’s expectations for esthetics (Figures 17 and 18). Designing of the final delivery of an ISFDP is recommended, especially for those diagnosed with

the final prosthesis was done in multilayered zirconia (Figures 20a to 20h).
The final prosthesis was screwed over the multi-unit abutments using tie- RESULTS
bases (Figures 21a and 21b). The occlusal pattern was again checked for Evaluation of marginal bone loss in implants loaded with multi-unit
any prematurities due to discrepancy in the design from temporary to final abutments revealed minimal to no bone loss after a 3-year follow-up. This

passively fitting prosthesis and thereby minimized unwanted oblique forces
STEP 9: PATIENT INSTRUCTIONS on the implants, contributing to their long-term stability. Furthermore,
The patient was instructed to maintain hygiene of the prosthesis and attend potential marginal bone changes associated with repeated screwing and
regular follow-ups for at least 6 months to one year, during which he was unscrewing of provisional and definitive abutments were avoided, as the
