HIS METHOD OF FITTING an immediate complete denture may be used as an adjunct to any technique of immediate complete denture construction. For the purpose of brevity, it will be assumed that accurate casts have been properly mounted on an articulator ready for the final arrangement of the teeth.
T
PROCEDURE
As each tooth is cut off the cast, the artificial tooth to replace it is placed in position. In most instances, no other modification of the cast is made. Occasionally, it may be expedient to do a slight modification in areas representing massive bony prominences. However, such trimming is always minimal, and it is not done to produce a cast form approximating that of the ridge following the completion of surgery. The set-up is completed. Subsequent laboratory procedures are carried out to produce a finished denture ready for delivery except for a final correction of the fit. At the next appointment, the surgical procedures are carried out first. It should be noted that during these procedures, only matters of surgical significance need be considered. Naturally, one of the objectives will be to produce a favorably shaped denture-supporting area. However, it is not necessary to attempt to shape the ridge to fit the denture as is done with clear acrylic resin templates or equivalent guides. When the surgery is complete, sutures are placed so as to close all socket openings entirely. If sutures cannot successfully close a socket opening, a ljatch of tin foil held in place with denture adhesive will su%ce. The denture may now be placed in position and checked as to occlusion and border extension. A space of varying dimension will be apparent between the surgically trimmed ridge and the inner surface of the adjacent flange. This is due to the fact that little, if any, modification was performed on the cast. For this reason, the denture will go to place very easily and without any suggestion of binding. The space, thus present, is to be filled by means of a corrective lining of activated resin adapted in the mouth directly to the surgically treated area. The denture is removed, cleansed, and dried in readiness for the activated resin correction. A pencil line may be drawn on the inside of the denture to The opinions or assertions contained herein are those of the author strued as official or as reflecting the views of the Navy Department at large.

outline the area to be corrected. This will aid in the proper placement and later trimming of the reline material. The polished surface and the teeth, if made of acrylic resin, should be lubricated to prevent the adhesion of excessive lining material as it escapes over the edge of the flanges. A mix of resin is prepared. When it has reached approximately the consistency of an alginate impression material, a suitable quantity is applied to the surface of the denture to be corrected. The denture is seated with firm pressure. The patient must close into centric occlusion and maintain steady pressure for one minute. Border-trimming manipulations may be accomplished during this interval. At the end of one minute, the resin will have become noticeably firmer. The denture is removed and examined for a possible deficiency or excess of reline material. Either should be corrected without delay, and the denture should be reseated. Again the patient is directed to close into centric occlusion and maintain steady pressure for several more minutes. The pressure is maintained until the reline material has become hard enough that removal of the denture cannot deform it. The denture is removed, rinsed clean, and placed in a bowl of water to bench cure. When the cure is complete, the denture is finished, polished, and ready for insertion in the mouth. The sutures and any fragments of acrylic resin which may have become enmeshed in them are carefully removed. The denture is dusted lightly with denture adhesive powder for added security during the first twenty-four hours, and placed in the mouth. The patient is given instructions as to the care of the denture, and an appointment is made for examination and treatment the following day. SUMMARY
A method for producing an immediate denture by a’ two-stage process of adaptation has been described. Initially, the denture is built to a cast with minimum modifications. The final correction and adaptation is accomplished following the extraction of the remaining teeth by use of an activated acrylic resin lining adapted directly to the surgically modified area of the mouth. CONCLUSIONS
1. An immediate denture technique which is adaptable to any patient and to all conditions has been described. 2. The method offers the dentist an opportunity to achieve consistent success in the fitting of immediate dentures. 3. The accuracy of fit provides excellent retention and stability. 4. Postoperative bleeding and edema are minimal. 5. Adjustments in the region of the surgery are rarely necessary. 6. The method is not unduly time-consuming, and the necessary materials are readily available. DENTAL DEPARTMENT, CODE 750 MARE ISLAND NAVAL SHIPYARD VALLEJO, CALIF.
