A reline is a procedure used to re-fit the surface of a denture to the tissues of the mouth. This is done by placing a new acrylic base into the denture, duplicating the new form of the oral structures in the mouth. A reline will bring back comfort, stability and discourage food from going under the denture.
Relines are required for many reasons with the most common reason being gum resorption (shrinking of the oral tissues). Gum resorption is caused by the normal process of aging or after natural teeth have been extracted.
A general rule of thumb is that dentures should be relined once every 2 to 3 years. Relines are a normal part of denture maintenance and important to the health of the oral tissues and bone support of a denture wearer.
A reline is not always recommended for a denture. If a denture has lost some retention and the "bite" or occlusion (contact of the teeth) has changed considerably a reline will not be satisfactory in correcting the retention. of the denture/s.
Types of Relines
A temporary reline (tissue conditioner) is a silicone gel designed to last 1 to 4 months. It is normally used in dentures of people who have had their natural teeth extracted or to improve the health of their tissues before new dentures are made.
A direct reline is also called a chair side reline. The direct reline material is inserted in the denture and sets in the mouth as the patient waits in the dental chair. The direct reline is offered in a hard or soft base, and are not meant as a long term solution to fit issues.
A processed reline is completed by taking an impression inside of the patient's existing denture duplicating the new form of the oral structures in the mouth. This impression is then processed in our in-house laboratory for approximately 7 hours. This is considered a permanent reline due to the high quality of material used and the precision of the fit achieved.
A soft liner is used mainly in full lower dentures and allows for more protection and comfort for people who have sensitive gums with little or no bone support.
The soft base is a liner that is bonded into your denture. Your denture will adhere better to what remains of your gum, be less irritating to your tissues and give your denture more stability. When constructing your denture, the Denturist will take an impression for the soft base and process it into the inside of the denture. The Soft liner material is a bonded medical grade rubberized base. Soft liners will last approximately 2 years.
Remember: relines do not change the color or shape of the teeth or make them sharper for chewing. A reline replaces the fitting surface of the denture to make it fit better.
A rebase is the process of refitting a denture by replacing the entire denture base. This procedure is done by taking a new impression inside the denture, completely removing the old acrylic and adding a new acrylic base around the existing teeth. This service is recommended for dentures that have had multiple repairs, discoloration or are very thin.
