However, the following factors should prompt a dentist to reconsider the use of a complete denture: Patient does not desire to have a removable appliance to replace missing teeth, Patient has an allergy to the acrylic used in the fabrication of the complete denture, Patient has a severe gag reflex (although this could be controlled with gag reflex desensitization), Patient has severely resorbed dental alveolar ridges, which would compromise retention with a complete denture alone. Gingival and periodontal causes: Because some disorders such as gingival hyperplasia, marginal gingivitis, and advanced periodontal diseases will turn into worse conditions when fixed dentures, which are more likely to cause periodontal and gingival sensitivity, are applied, prosthetic procedures should be performed after such disorders are treated and prevented from relapse. Because of short preparation time, removable dentures can be preferred for old patients because they may not tolerate the processes of the fixed partial dentures. Jay R. Beagle DDS, MSD.

Ordinarily, this type of prosthesis must be relined periodically as the underlying tissues heal and remodel. Reverse ball-and-socket shoulder prostheses were initially introduced in the 1960s to treat patients with glenohumeral arthritis and massive rotator cuff tears. If you log out, you will be required to enter your username and password the next time you visit. Such liquid bridges are similar to those that form when a water droplet is held between the fingertips. [12]. [6]. In Vitro Assessment of the Abrasion Resistance of Two Types of Artificial Teeth Submitted to Brushing. June 28th 2012. Therefore, we can distinguish some contraindications to dental implants: relative and absolute, which limit or prevent the implantation procedure. [7, 8] A retentive pressure within the liquid-filled space develops and facilitates denture retention. The socket has to be efficiently fitted, have adequate load transmission, and it needs to ensure stability and control. After the indication, the precautions and contraindications should be considered as balancing components of the decision-making and informed consent process. http://canada.dentalcare.com/media/en-US/dcn/zarb.pdf. 228 Color Pages .

The custom tray circumscribes and accommodates for anatomy needed in the fabrication of the final denture. In addition, consideration is made as to whether the patient’s life expectancy and physical status justify such a … The cast is evaluated for anatomical constraints, including, but not limited to, tori and undercuts. A plastic spacer is introduced between the metallic surfaces to ensure smooth movement. Stability is much higher in bridges firmly connected to the support teeth than that of removable partial dentures. With overdentures, locator attachments are sometimes secured within the remaining roots or within placed dental implants, and these components are known to improve retention.

Contraindications are also divided into two groups; Patients who cannot be adapted: Fixed denture applications may be contraindicated for two reasons, psychologically or medically: Fixed denture applications may not be appropriate for very young and very elderly patients who cannot tolerate detailed preparation and sensitive measurement procedures of prosthetic applications psychologically. However, developments in local anesthetics and appropriate consultations with medical disciplines can eliminate this kind of causal conditions. Today, dental implants are the state-of-the-art tooth replacement systems and are now more common than ever before. [11] Some estimates commonly reported by dentists include 5-7, 10, or even 10 plus years.

Denture adhesives, in addition to enhancing cohesion and adhesion more than saliva, improve denture retention through elevated viscosity values. In cases where there is no support teeth or they are not sufficient, the routine use of implant supports gradually reduces removable dentures applications although they are considered as an important alternative. Absolute contraindications Some serious general conditions create anesthesia, surgical procedures and the overall placement inadvisable. For the patient who has lost the anterior teeth due to trauma and formed an inappropriate appearance on the lip due to the scar tissue formed, an acceptable appearance had been obtained after the scar tissue was surgically treated and dental bridge was placed. 1874; 69:713.

Attempts had been made to model and approximate the capillary forces involved. During the healing process, this denture helps to confine the remodeling of the underlying ridge to the interior of the denture. The following are indications for this type of dental prosthesis: Dental implants that have been deemed inappropriate by patient and/or doctor because of financial constraints, a medically compromised status that contraindicates surgery, or inevitable damage to vital structures such as maxillary sinuses, nerves, and vessels, Intraoral cancer that has caused a loss of gross intraoral tissue, resulting in an edentulous dental arch; the complete denture prosthesis would then not only replace teeth but also fill in the portion of missing tissue (eg, nasopharynx, hard palate). The aim of this study was to review the current scientific literature in order to analyse the indications and contraindications of dental implants in medically compromised patients. The master cast is fabricated from the recordings of the custom tray. Prosthetic Considerations. [2, 15] Other denture cleaners are available, but caution should be exercised when using mild acids or hypochlorites, as they are known to corrode metals. Occlusal relationships are evaluated.

As both the surgical techniques and prosthesis components improved, these considerations were refined and broadened. /viewarticle/932408 Crest form: If tissue loss in the crest form in the toothless area is considerably over after the application of fixed denture, which can cause problems in terms of aesthetic and phonation, then removable partial dentures or fixed removable partial dentures (Andrew bridge system) should be applied. The basis for modern dental implants is a biologic process called osseointegration where materials, such as titanium, form an intimate bond to bone. 8. With meticulous attention to oral hygiene, responsible care and handling of the complete denture, and careful attention to a proper diet, dentures may conceivably last longer than expected.

These include spatulas, wax, casting ovens, impression material, adhesives, dental trays, border molding compound, shade guides, and a torch. J Prosthodont. [Medline].

However, there are also studies stating that the growth and development continues until 20 years of age in girls and 22 years in boys. Therefore, the indications and contraindications of fixed dentures should be inspected carefully.

Improper tilting or rotation of the teeth: SECTION-1: INTRODUCTION TO FIXED DENTURES, Section 1: Introduction to Fixed Dentures, » 9.3. [12] It is advised that patients practice reading out loud to allow quicker accommodation to the new prosthesis. This coincides with the clinical practice of maximizing the denture base coverage but without infringing on the neutral zones. The principal contraindications for shoulder replacement include an infection in progress, Charcot's arthropathy and severe neurological pathologies. A reference research was carried out on PubMed using the key words “implant” AND (oral OR dental) AND (systemic disease OR medically compromised), in articles published between 1993 and 2013. Roots and dental implants help to preserve bone, and the added retention is known to be greater than conventional complete dentures alone. Various protocols and techniques are available for processing complete dentures. Heart diseases affecting the valves, recent infarcts, severe cardiac insufficiency, heart disease Active cancer, certain bone diseases (osteomalacia, Paget’s disease, brittle bones syndrome, etc.) [10] "V" represents velocity of displacement, helping to show that viscous tension is more effective in resisting high moments than prolonged displacements. Where "r" represents the radius of the plates, it is understood that an increase in the surface area of the denture-mucosa interface would improve retention by the power of 4. This website also contains material copyrighted by 3rd parties. Depending on the type of prosthesis, other concerns include skin grafts, skin hypersensitivity, short stump length, 3 blindness, 3 … If one finds that removing and inserting the denture is challenging, a follow-up appointment must be made with the dentist for further instruction.
