REMOVABLE CAST METAL FRAMEWORK OR IMPLANTS?
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
2. 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.
a. The feeling
Metal Framework: It takes time to adapt to chewing. Sometimes it's painful and comfortable
Implants: Attached to the fixed jaw, fit, comfortable when chewing
b. Function
Metal Framework: The chewing ability is significantly improved compared to the plastic framework
Implants: The chewing function is superior to that of natural teeth
c. Longevity
Metal Framework: Short, need to change often
Implants: Durable forever, no need to restore
d. Aesthetic
Metal Framework: Minimize the thickness of the gums but not beautiful, easy to recognize dentures
Implants: Maintain facial structure, natural smile, more beautiful than real teeth
e. Conservation
Metal Framework: Can be oxidized. Real jawbone loss is still happening
Implants: Existing independently, does not affect adjacent teeth. Prevents none resorption
f. The price
Metal Framework: The 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
Implants: The cost is quite high
g. Care Process
Metal Framework: Quite inconvenient, must be disassembled for regular cleaning
Implants: Easy and convenient care
h. Manufacture time
Metal Framework: Quite fast
Implants: Depending on the condition of the teeth and mouth and the type of abutments chosen by the customer
Conclusion: You should only choose a metal framework temporarily when there are not enough economic conditions. The implant is the optimal solution and worth investment. Both aesthetic, high chewing food and ensure long-term health.
