Complete Dentures

Conventional and Immediate are the two types of dentures available.
A conventional denture is manufactured and positioned in the patient's oral cavity after the remaining teeth are extracted and tissues have recovered. The procedure can last for some months. Unlike Conventional appliance, Immediate appliance is placed as soon as the remaining teeth are extracted. Immediate appliance's main benefit is that the patient does not have to stay without teeth. During the healing period, gum and bone shrinkage occurs due to which the immediate appliance has to be realigned. After the recovery is complete, a conventional appliance is then made.


Manufacturing a Complete Denture

Every minute detail has to be considered while fabricating a complete denture as ignoring even the smallest factor can cause failure. In many cases, the appliance is required to fit easily soon after being placed. One of the most significant fact of the procedure is that the imprint must be faultless and the technique implied to make it must be flawless. Border molding process must be used by the dentist to avoid the aggressive collision of the denture with the edges of the oral cavity. Patience is essential while designing a denture and even the slightest of mistake and cause a whole assortment of problems later.

The stable alignment and low slippage makes full upper denture easy to design. In case of lower appliances, the dentist recommends using 3-4 implants in lower jaw as support due to lack of ''suction'' to maintain the appliance in its position. The one big benefit of using implants as support is that the patient can enjoy biting an apple or a corn which becomes extremely difficult without implants.

Statistics have shown full dentures have less biting power than natural teeth and do not always fit comfortably. Such patients need to realize that while upper denture can remain stable without implants, lower denture cannot. Hence, dentist always recommend of keeping as many natural teeth as one can especially in the lower jaw.


Freshly Inserted Dentures

Newly inserted appliance may feel a little awkward in the initial phase as the tongue and muscles of the cheek are still adjusting themselves. Minor irritation, tenderness and increased saliva level are very common and normal problems that a patient faces after getting new appliance. 1 or 2 visits to the dentist are essential after insertion.

To avoid appliance slippage, the patient should slowly graduate from easy to chew food to normal diet as this process requires practice. Even after getting used to the appliance, a patient must take extreme care while eating hard food, food with sharp edges and hot food. Food should be chewed by using both sides of the oral cavity simultaneously.

Teeth are necessary to correctly pronounce certain words and reading out loud and repetition of difficult words helps improving diction. Talking slowly helps avoiding ''clicking'' of the appliance. Sporadic slippage might occur while coughing or laughing hard and can be adjusted by gently biting and swallowing. The patient should immediately visit the dentist if any of the above mentioned problems persist.

We will give instructions about the time for which the appliance must be worn. During the initial phase, the patient may be advised to use them most of the time and also while sleeping. After the early adjustment phase, the patient may be asked to not wear them while sleeping. This is done to encourage healing and oral health. As a rule of thumb, the gum tissues should not be continuously surrounded by the appliance.


Problems with Complete Dentures

    Following is a list of problems usually associated with complete dentures.

  • Saliva - Increased saliva level occurs after insertion as the human brain "senses" the appliance as food particle. The patient is required to take conscious efforts to get used to the appliance and not think of it as food.
  • Sore Spots - Rubbing and pressure on the mucous membranes of the oral cavity causes soreness in many patients. This issue is resolved by ensuing adjustments in following weeks.
  • Gagging - Loose fitting or optimal extension of the appliance on the palate causes gagging in some patients. Psychological rejection of the appliance is said to be another reason behind gagging. As psychological problems are not in a dentist's domain, the patient is offered a psychologist's referral or an implant supported palate or both.
  • Gingivitis - Accumulation of dental plaque under the appliance gives rise to gingivitis. Inflammation of the gum and soreness are common conditions in gingivitis. The issue is usually reversible and gum inflammation subsides in about a week if thorough cleansing of the appliance is done. Plaque and calculus can be removed very easily by a dental hygienist or a dentist. Following a professional cleaning service, patients must be unrelenting with their oral hygiene care. Proper and regular oral hygiene routine which includes brushing, flossing, rinsing with anti-bacterial mouthwashes can help reduce swelling and avoid remission of gingivitis. Antiseptic mouth gels can also help with gingivitis and they are normally anesthetic in nature too.
  • Movement: Support, Stability and Retention - Positioning of the appliance is another area of where a patient may experience difficulty. There are 3 rules which command the presence of removable appliances viz Support, Stability and Retention.
    • Support - The efficiency of the underlying oral tissues in keeping the appliance in place describes support. Implants are now being considered as an option to increase stability. Deterioration of the resting ridge or complete disappearance occurs as time passes but can be avoided by inserting implants into the bone under the appliance. Implants help distribute the pressure exerted on the appliance while chewing which in turn prevents melting of the bone. When implants are incorporated into the procedure, the appliance is now called as an implant supported overdenture and the implants are called as overdenture abutments.
    • Stability - Prevention of sideways sliding or front to back sliding describes the stability. Stability increases as the contact of the appliance with the ridge becomes smoother and continuous.
    • Retention - The ability of the oral cavity to avoid moving of the appliance in the direction opposite to that of insertion describes retention. Retention capacity increases as the quality of the surface of the foundation to the surface of the subdural membrane increases. The most significant element in the retentive blueprint of a full upper appliance is an absolute border seal in order to get 'suction'.

Complete Dentures and Implants

Recent studies have caused an increase in the number of dentists opting for implants while using dentures. The benefits of implants mentioned above have caused this change of mindset.


Conclusion

The production of a complete denture appliance is a test for any dentist, amateur or expert. Removal of sore spots requires at least 2-3 follow up visits to the clinic. The upper appliance is molded to work in sync with the lower appliance. To avoid slippage of the appliance while opening, closing or swallowing, the dentist sets the teeth if the patient's ridge and 2 appliances are the only variables. Entry of food into the picture can disrupt the process as the appliance base moves while chewing food. Using adhesive to avoid moving of the appliance in any form or shape is recommended as unlike a perfect world the base does not fit perfectly even though the patient has an ideal edentulous ridge.

Old and poorly fitting appliances are not suitable for dental adhesives as they can cause continuous irritation and may lead to growth of sores. The patient should immediately contact the dental practitioner if he/she experiences looseness in the appliance, difficulty while talking as the appliance may need relining or replacement.

Due to natural wear and tear, denture need to be adjusted or remade by using existing teeth on the denture as reference points. In case the appliance becomes too loose or shows greater signs of wear and tear then they need replacement. This is caused to aging as the natural position of the jaw changes due to shrinking gums and teeth. Change in facial features and difficulty in chewing food are the problems caused due to reduction in size of the ridges. Hence, it is vital to replace old or poorly fitting appliances before they start causing grave oral or health problems.


Flexible Dentures

Now nobody needs to realize that you're teeth are gone

Introducing VALPLAST Flexible Dentures
The best and least expensive choice is using flexible partial dentures which are very aesthetic in appearance too. The idea that the rigidity of the partial removable dentures was essential for it's effectiveness has been proven wrong by the innovation of the Valplast Flexible Partial which permits the appliance to adjust itself to the continuous movement and flexibility in a patient's oral cavity.

Features like flexibility, light-weight, strength, beautiful appearance and complete comfort have given rise to the Valplast Flexible removable denture.

No alteration of the natural teeth is necessary while preparing a Valplast partial. A patient's beautiful smile is the only thing noticeable as the Valplast partial is camouflaged in the oral tissues and does not have metallic claps to draw attention.

Quick manufacturing of the final appliance and total comfort make Valplast partial the favorite choice of patients who opt for removable partial. Beautiful end results and satisfaction offset the high cost of the Valplast partial. A great smile, confidence in the appliance while talking or chewing food and non-invasive process are additional features of Valplast partial.


Patient Care Information

    Majority of the patients become quickly familiar to the delicate and light-weight Valplast partial. Inexperience of a dental appliance may give rise to slight adjustment phase. Persistent irritation should not be ignored and the patient should visit us as soon as possible to fine tune the restoration.

    Following instructions need to be followed to maintain the natural look and strength of the Valplast partial:

  • Valplast appliance should be cleansed on a regular basis and thoroughly.
  • Valplast appliance should be kept in water overnight or for 10 to 15 minutes a day at least thrice a week.
  • Sonic denture cleaner or running water can be used to rid the Valplast appliance of any food particle. Valplast appliance should not be brushed as it leads to decreased level of polish and makes the surface uneven.
  • Valplast appliance should be rinsed after every meal if possible.
  • To maintain the hydration of the surface, Valplast appliance should be kept in denture cleaner or water when not being used.
  • Natural teeth and gums should be brushed regularly as per the suggestion of our dentist.

Additional Tips:

  • Valplast appliance should not be soaked in denture cleaners of local brand as they may contain ingredients that damage it or cause discolouration.
  • While brushing the natural teeth, Valplast appliance must be removed and kept in either water or recommended denture cleaner as the toothpaste and toothbrush can scratch the surface or reduce the shine.
  • Valplast appliance should be kept out from reach of children and pets.
  • Under normal usage, Valplast appliance last for many years. Valplast appliance base material is better at resisting fractures or cracks than the artificial teeth integrated in it but minor accidents such as dropping on the floor or in the basin may cause the artificial teeth to fracture or crack.
  • Extreme care should be exercised while handling Valplast appliance.
