This causes a new set of problem when patient has to go for FMR and bite increase. The earlier done prosthesis keeps being unretentive and keeps dislodging causing an increased incidence of mutilation of those teeth due to acute caries. This happens because of creation of concentration cell gradient due to flooding by saliva in the partially dislodged prosthesis. If one must then resort to metal crowns in posteriors or inform patients of risk. I have also noticed that some doctors do occlusal cutting during FMR with bite rise or fear raising the bite or are unclear of parameters for raising the bite. Prosthodontist or a TMJ specialist help must be taken.
