Hard Relines:
 Some of the newer hard relines can be performed in office or chairside and still be considered long lasting. With an office reline the reline material is cured in the office at the time of the reline. Because of the nature of material used it is not considered as accurate and long lasting as a laboratory reline.

A Laboratory Reline is still considered the best type of reline available and the longest lasting. The plastic is processed and cured in the laboratory in the same way that the plastic of the original denture is cured. The biggest disadvantage of a Laboratory Reline will require that you are without your denture during the laboratory phase. 

 Soft reline: 
A soft reline can be performed either in office or chairside or in the lab. Neither is considered as long lasting as a hard reline. In the case of soft relines the laboratory reline is considered superior to a charside reline. 

Reasons for a Denture Reline:

• Better fit, a relined denture "stays in better"
• A better fitting denture helps the dental ridges stay healthy
• Helps a denture last longer
• Helps with proper nutrition and health
