Removable Cast Metal Framework is one of the dental restorations that raise concerns from customers. Is cast metal framework good? Compared with the implant, which one is better? This article will help you understand more about the advantages and limitations of Cast Metal Framework

1. What is the removable cast metal framework?

A removable cast metal framework consists of 2 main parts are jaw base and the denture. However, this type of restoration is designed with hooks resting on the chewing surface of the natural teeth and a metal arc (it can be Cr – Co, Ni – Cr, or Titanium alloy) leaning close to the anterior tooth arch to create more stability than traditional flexible plastic jaws.

Dentures attached to the jaw frame are porcelain teeth or plastic teeth, depending on the customer’s choice.

The dentists usually recommend removable cast metal framework to people who have lost a few teeth or groups of teeth on the arch.


2. Advantages of the cast metal framework

Compared with plastic frameworks, metal frames have more outstanding advantages to help improve the patient’s tooth function. Patients who are less budget for fixed dental restorations but still want to have relatively aesthetic teeth, to improve chewing, easy cleaning should choose this method.

a. Improve chewing function

Due to the metal frame, it transmits force well. The limitation of free movements helps the jaw be more stable when chewing, which causes less harm to the abutment teeth compared to the plastic framework.

b. Easy to use

The titanium jaw base is firm and lighter than the plastic framework, so the frame jaw will reduce the feeling of entanglement in the tongue, helping patients shorten the time to adapt, eating and drinking will be more delicious.

c. The Hygiene

The metal surface is compact and shiny, so it does not absorb saliva, oral fluid, and food, so it helps to improve hygiene after eating

d. Greater durability

Because it is a metal structure, it is more durable than the hard plastic and flexible plastic jaw bases. Besides, it will not break if dropped or due to careless use.

3. Limitations of metal frameworks

Although the metal frameworks have many outstanding advantages over flexible and hard plastic frameworks, they still have some disadvantages that make many patients wonder when choosing.

a. Higher cost

Clinical design and manipulation require high technology and are more complicated, so the cost of metal frameworks is also higher than that of plastic jaws.

b. Only used for a few cases

This type of restoration is only applicable in certain cases of tooth loss. Specifically, metal frameworks only apply to patients who have lost individual teeth or a group of teeth on the arch.

c. Unwanted complications

This type of restoration attaches to the natural teeth that can affect natural teeth – make the real teeth pull, even weaken. Customers who eat chewing will sometimes feel sensitivity and discomfort. Therefore, the doctor who makes the jaw must have experience, the design of the frame must ensure the criterion of eliminating the bad force acting on the abutment teeth. If the dentist indicates wrong, it will harm the abutment teeth.

4. Compare metal frameworks and the implants

Two methods of making metal frameworks and implants are being commonly applied to restore lost teeth. So, the comparison between the metal frameworks and the implants will help your decision to achieve the best effect.

LongevityShort, need to change often.Durable forever, no need to restore.
AestheticMinimize the thickness of the gums but not beautiful, easy to recognize dentures.Maintain facial structure, natural smile, more beautiful than real teeth.
ConservationMetal frames can be oxidized. Real jaw-bone loss is still happeningExisting independently does not affect adjacent teeth. Prevents bone resorption.
The priceThe cost is higher than plastic frameworks there is an additional fee for bonding dental crowns, the cost for a complete set of jaws will be higher.The cost is quite high
Care ProcessQuite inconvenient, must be disassembled for regular cleaning.Easy and convenient care
Manufacture TimeQuite fastDepending on the condition of the teeth and mouth and the type of abutments chosen by the customer
ConclusionYou should only work temporarily when there are not enough economic conditions.Is the optimal solution and worth investment. Both aesthetic, high chewing food and ensure long-term health.
