Immediate or transitional complete dentures: gerodontic considerations.

Ageing society is a worldwide phenomenon, especially in western countries, were the proportion of the aged population reaches about 20%. Of this group about 50% constitute what is termed the old-old frail persons who suffer drastic physiological changes which exacerbate difficulties in classic dental and prosthetic treatments. Epidemiological surveys point out that many of the elderly present with about 12-14 teeth with bad periodontal conditions that should be extracted. As a result, special strategies have to be elaborated to give an appropriate solution to specific medical and prosthetic conditions. Transitional procedures are necessary to assure the smooth change between removable partial dentures and complete dentures. Even when implant supported dentures are planed this transition period is necessary. Clinical decision making is crucial to avoid stress to these medically compromised patients.

Oral mucosa and complete dentures.

The reduction in the epithelial thickness under dentures did not reach the level of significance. The significant reduction in the epithelial morphology indicating a flatter basement membrane would suggest that the epithelium undergoes an adaptive change as a result of surface loading to produce a more uniform epithelium. The degree of keratinization was less and the stratum corneum was thinner in the epithelium under dentures. The complete dentures in these studies seemed to reduce the quantity and quality of the keratin layer. This study has shown that the presence of a denture produced a more regular epithelium with few rete ridges, and a thinner, less highly keratinized stratum corneum.

Experimental studies of adaptation to complete dentures related to ageing.

The assessment of a patient's capability to adapt to new dentures is still a challenge in the prosthetic treatment of geriatric patients. The aim of this study was to assess the relationship of age to manual motor ability as well as the mental concentration capacity in comparison to the oral motor ability and the capability to adapt to new dentures. Sixty complete denture wearers volunteered for the experiment. The results indicate, that the manual motor ability and the mental concentration capacity deteriorate with age, whereas the relationship of age to adaptation to new dentures and oral motor ability is less obvious. This may be due to the patient's denture experience.

Effects of a denture adhesive on masticatory functions for complete denture wearers--consideration for the condition of denture-bearing tissues--.

The purpose of this study was to examine effects of a denture adhesive on masticatory functions for complete denture wearers considering the condition of denture-bearing tissues. Sixteen edentulous subjects wearing well-fitting complete dentures volunteered to participate in this study. According to the condition of denture-bearing tissues, subjects were divided into two groups; "good group" and "poor group". Maximum biting forces, masticatory performance, and electromyography of the masseter muscle during mastication were recorded with and without a denture adhesive. Durations of chewing burst and cycle, and coefficients of variation for these variables were calculated using electromyography recordings. Data were analyzed by using two-way repeated-measured ANOVA and paired t-test in order to assess the effect of the use of a denture adhesive. The use of the denture adhesive increased maximum biting force and provided rhythmic masseter muscle activity during mastication for both groups. Masticatory performance was improved and duration of chewing burst was decreased only for "poor group". It was concluded that the effects of the denture adhesive on masticatory functions were observed overall for both groups, and more significant for denture wearers with poor denture-bearing tissues than with good denture-bearing tissues.

[Single mandibular complete dentures].

Single mandibular complete dentures suffer greater pressures as the basal seat area available is limited and the opposing arch consists more or less of natural teeth. The practical approach of such a case is described. Study casts mounted on a Hanau-H or Dentatus articulator help the dentist form a clear picture of the existing relationships and avoid underestimation of problems and preposterous restorative procedures. Reducing and reshaping upper natural teeth by grinding in order to equilibrate the occlusal scheme becomes unavoidable in such cases. So, the patient should be informed about it from the very beginning. Jaw relation records should be verified and be absolutely correct before setting the lower posterior teeth and performing any major reshaping of the remaining upper teeth. The existence of natural teeth does not usually permit succeeding a bilaterally equilibrated occlusion. So, the posterior teeth are usually set into a cusp-to-cusp relationship and a balancing ramp is properly formed behind the last molars bilaterally, so that a three-point contact is provided in all eccentric movements, if possible. The need of remounting the casts through new interocclusal records and before delivering the denture to the patients is explained in detail. As the acrylic base exhibits dimensional changes long after the insertion of the denture, this occlusal adjustment has to be repeated more than once frequently. If, in spite of these adjustments, the lower denture continues to give symptoms, then the use of some kind of resilient liner is recommended.

Introducing dental students to clinical patient care: the Complete Denture Prosthodontics Transition Clinic.

Using complete denture treatment as an introduction to clinical patient care for dental students, the purposes of the Complete Denture Prosthodontics Transition Clinic at the University of Colorado School of Dentistry are to reduce the time lapse between the preclinical complete denture prosthodontics course and the first denture patient experience, and to encourage development of student self-confidence and skills. In the 2002 spring semester, faculty at the University of Colorado School of Dentistry initiated the Complete Denture Prosthodontics Transition Clinic for DS-II (second-year) dental students, as an introduction to clinical patient care. Each patient was assigned to a team of two dental students. Three Division of Prosthodontics faculty members staffed each clinic session, providing a student-to-faculty ratio of approximately 6.6:1 and a patient-to-faculty ratio of approximately 3.3:1. All DS-II students in the Class of 2004 delivered their first complete dentures no later than 8 months (average, 184 days) after the last day of the preclinical complete denture prosthodontics course. The time from the diagnostic appointment through the denture placement appointment averaged 39 days for patients treated in this program, compared with an average of 98 days or more for previous classes. The program was successful in achieving the goal of reducing the time lapse between the preclinical complete denture prosthodontics course and the first denture patient experience.

Normative and subjective need and utilization of complete denture services.

The need for complete denture treatment was compared to utilization of complete denture services. To estimate the need for complete denture treatment we used data from the Mini-Finland Survey which included 3620 persons who were edentulous in one or both jaws. Data about utilization of services was obtained through questionnaires sent to samples of dentists and special dental technicians. Utilization of services was 21.8% of the need assessed with professional criteria and 17.7% of the subjective need. Compared to the subjectively assessed need, utilization of complete denture services was highest among young women and lowest among men aged 60-69 yr. Subjective need for denture services was highest in older groups. From these results we conclude that certain barriers prevent patients from seeking care; and as these barriers are reduced, use of complete denture services may increase.

Common faults in complete dentures: a review.

Complete-denture therapy involves a complex interplay between biologic demands and technical limitations. Success with complete-denture therapy is reportedly high. Dissatisfied denture patients, although few, do exist. This paper reviews some of the common faults reported with complete dentures.

[The stability of complete dentures in the construction of functional movement patterns].

In a cross-sectional study involving 185 full denture wearers, the stability of upper and lower dentures was determined by means of active test movements according to Herbst. The percentages of instable dentures and their confidence intervals were calculated. It was found that all sections of upper full dentures can be regarded as equal with regard to stability, whereas the sections of lower full dentures showed considerable differences. Finally, practice-relevant conclusions are drawn from the results of the present study.
