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. However, implants may not always be a solution because of some anatomical and systemic limitations. 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. THOMPSON FR. Usually, after 6 months, a conventional complete denture is indicated (ie, a new denture). To allow for optimal functioning with the complete denture, it is recommended that patients place food bolus on both sides of the mouth and to chew with both sides. Therefore, the indications and contraindications of fixed dentures should be inspected carefully. St. Louis, MI. Although the model applies directly to relationships between two circular plates, it is not unreasonable to project such a relationship to the denture, saliva, and mucosa interfaces. Maintenance and repairing: Maintenance and repairing of fixed partial dentures is more difficult than that of removable partial dentures. Pre-Surgical Workup. Does the Prevalence of Periodontal Pathogens Change in Elderly Edentulous Patients after Complete Denture Treatment?. Periodontal Causes: When the periodontal problematic teeth which show no extensive mobility and are connected to healthy teeth with fixed prostheses (splinting) can be kept in the mouth for a long time as a result of the distribution of the pressure on these teeth to the healthy teeth with periodontal treatments. So, if necessary, removable dentures can be preferred. After such an operation requires a long course of rehabilitation. Also, the fixed partial dentures applied for patients in growing period are not suitable as they will have negative effects on bone development. Roots and dental implants help to preserve bone, and the added retention is known to be greater than conventional complete dentures alone.

Author information: (1)1 Icahn … PDI considers factors such as patient's psychology, tongue anatomy, maxillomandibular relationship, arch morphology, muscle attachments, and interarch space.  Some factors that could lead to good prognosis according to the PDI include proper maxillary-to-mandibular relationship (ie, class I as opposed to class II), normal quantity and quality of saliva (as opposed to ropy saliva), U-shaped arch (as opposed to a V-shaped arch), prior use of dentures, and a positive mental attitude (as opposed to indifference or pessimism). This mechanism is independent and not related to that of atmospheric pressure differentials. High Decay Incidence: Since fixed dentures provide additional environment for decays in the mouths in which decay incidence is high, endodontic and conservative treatments must be performed very well before the applications and dentures should be prepared very carefully. Possible tooth losses in the same arch: Fixed denture applications can be postponed to prevent long and expensive procedures from being repeated if the teeth that are in the same arch and need to be included in the fixed partial denture aplications are lost in the future. www.indiandentalacademy.com 7.

Age of Patient: Fixed bridge dentures may be contraindicated for very young and very elderly patients. The occlusion forces are transmitted to the periodontium through the support teeth and the neuromuscular system through the alveolar bone and jaws. Maxillary complete denture used to restore the upper ridge and a mandibular partial cast denture placed to restore mandibular partial edentulous regions. 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. In most cases, the first adjustment should occur within 24 hours of delivery of the complete denture. Stefan’s law, When hovering over a sink, it is recommended to fill the sink with water or to have a towel placed underneath in case the prosthesis falls. Mpungose SK, Geerts GA.
