The fees for NSRT were $944.65 for general dentists and $1,256.48 for endodontists. The fees for crown lengthening were $553.08 for general dentists and $924.20 for periodontists. The fees for porcelain-fused-to-metal crowns were $945.27 for general dentists and $1,380.20 for prosthodontists. The fees for post and core were $269.65 for general dentists and $397.71 for prosthodontists. The fees for extraction followed by a fixed partial denture were $2,957.07 for general dentists and $4,253.75 for specialists. The fees for extraction and single implant-supported crown were $3,771.25 for general dentists and $4,569.95 for specialists. The fees for endodontic microsurgery were $698.06 for general dentists and $1,089.88 for endodontists.
The survival rates were 87% for NSRT, 94% for endodontic micro-surgery, 89.1% for fixed a partial denture, and 94.5% for a single implant-supported crown.
The effectiveness was divided by the costs, for general dentists and for specialists. For general dentists, the results were 0.1347 for endodontic microsurgery, 0.0460 for NSRT with restoration, 0.0403 for NSRT with post and core then restoration, 0.0356 for NSRT with crown lengthening, then restoration, 0.0320 for NSRT with crown lengthening, then post and core, then restoration, 0.0301 for a fixed partial denture, and 0.0251 for a single implant-supported crown. The same ranking was found for specialists.
The sensitivity analysis showed that this ranking was generally stable to variations in the model parameters; a lower survival rate for NSRT made these options less cost-effective compared with the two extraction options.
