Fig. 5. Anterior portion of resin prosthesis is adjusted until it fits over splint bar and is properly aligned with abutment teeth.

PROCED 1. Construct an immediate interim mucosal-borne resin prosthesis after the splint bar fixed prosthesis is fully planned and preparatory treatment is completed. 2. Insert the immediate interim prosthesis after associated surgery (Fig. 1). Wrought wire clasps for the canine abutments are optional. This prosthesis will later be modified to fit the temporary crowns used after the abutment teeth are prepared for the splint bar fixed prosthesis. 3. Seat the fixed prosthesis and verify the fit. Section the labial flange with the artificial incisor teeth from the remainder of the interim prosthesis (Fig. 2). The posterior portion of the prosthesis is adjusted until it fits passively in the presence of the splint bar prosthesis (Fig. 3). 4. Block out the undersurface of the splint bar and make an irreversible hydrocolloid pickup impression with the posterior part of the interim prosthesis in position (Fig. 4). The utility wax is used to prevent the impression material from tearing when removed. Pour the impression in fast-setting dental stone. 5. While the dental stone is setting, adjust and permanently cement the splint bar. 6. Remove the stone cast and interim prosthesis from the irreversible hydrocolloid impression and adjust the anterior flange segment until it fits properly over the stone cast replica of the splint bar (Fig 5). 7. Join the anterior segment to the remainder of the interim prosthesis with repair resin and also establish close adaptation of the prosthesis to the elements of the splint bar fixed prosthesis.





6. Repair resin is used to join two segments and repaired interim prosthesis is inserted over splint bar.


8. Recover the repaired prosthesis from the stone cast, finish, polish, and insert over the cemented splint bar prosthesis. Wrought wire clasps may be added during the repair, but clasps are seldom necessary because of the precise fit of the anterior flange segment against the mesial surfaces of the abutment teeth and the stability afforded to the removable prosthesis by the bar (Fig. 6). 9. The final prosthesis is now constructed.

SUMMARY A procedure is described for the adaptation of a provisional all-resin prosthesis to an anteriorly placed splint bar. The procedure avoids any periods when the patient will be without a prosthesis to replace the anterior teeth. The ease
