Clinical evaluation of patients eight to nine years after placement of removable partial dentures.

Removable partial dentures, constructed following principles outlined in this study, provided reasonable service for an 8- to 9-year period for patients who were wearing them. The oral hygiene of the patients was less than ideal. Few teeth were lost by patients in the study. There were no significant differences in caries incidence, changes in sulcus depths, tooth mobility, or alveolar bone loss between patients who were wearing their dentures and those who were not. There were increased levels of gingival inflammation seen in regions covered by the removable partial dentures and in gingivae apical to clasp arms. Other than these findings, there seemed to be no direct evidence that the removable partial dentures were causing dental or periodontal breakdown.

Technical failure rates of double crown-retained removable partial dentures.

Removable partial dentures (RPD) can be retained using conical crowns or parallel-sided telescopic double crowns. The purpose of this study was to evaluate and compare the technical failure rate of the two retainer systems. One hundred seventeen dentures made by dentists of the medical school were included. Seventy-four RPD were retained with parallel-sided crowns (n = 251) and 43 with conical crowns (n = 160). Following the medical report follow-ups from January 1992 to December 1998, technical RPD failures were noted and analyzed. Technical problems occurred during the observation time in 48.8% of the conical retained dentures and 34.2% of the parallel-sided retained dentures. In both cases, loss of cementation was most frequently noted, while loss of the facings occurred only with conical crowns. Other technical failures did not depend on the type of retainer system used. These were most frequently problems with the denture base, e.g., fracture of artificial teeth or the metal framework. We conclude that there were different technical failures of both double crown retainer systems. These problems were not insignificant in number but treatable.

A clinical overview of removable prostheses: 3. Principles of design for removable partial dentures.

Removable partial dentures (RPDs) should not be made for patients unless they are necessary. Most partial dentures have the potential to cause some damage to the teeth and supporting tissues, however well they are designed and constructed; the criteria for selecting such devices were described in a previous article. In general there is merit in, wherever possible, reducing tissue coverage as much as possible when RPDs are being planned. This article, the third in a series on the prescription of RPDs, discusses the design principles involved.

Comparisons of tactile thresholds between implant-supported fixed partial dentures and removable partial dentures.

This study compared the tactile sensitivity of splinted abutment and denture teeth of 16 fixed partial dentures (FPD) supported by blade implants and 16 removable partial dentures (RPD) in patients with Kennedy Class I and Class II edentulous conditions. No significant differences were noted between the tactile thresholds of the natural abutment teeth and artificial teeth in the FPD and RPD groups. The splinted abutment teeth required 45.4 g, or 5.4 to 5.8 times higher occlusal loads than did those needed for the comparable nonsplinted teeth, to detect the stimulus. A further increase of 54% in thresholds with the FPD and over 100% with the placement of the RPD indicated the superiority of the RPD in terms of load distribution as a result of the cross-arch splinting and mucosal support. Moderate positive correlations (r = 0.37 to 0.46; P < .05) between tactile thresholds and masticatory performance were found, signifying that reduced tactile perception was not responsible for the incomplete restoration of the masticatory function with RPDs or FPDs but might be contributing to increased masticatory performance within both treatment groups.

A procedure for fitting a fixed partial denture to an existing removable partial denture.

An indirect technique for fitting a new cast gold crown or fixed partial denture (FPD) to an existing removable partial denture (RPD) is presented. This method uses an acrylic resin coping made on a definitive cast fit directly to the patient's RPD intraorally, with the new FPD subsequently completed on the cast. The patient does not have to relinquish the RPD for laboratory procedures, although an appointment is required to fit the coping intraorally where contact is made with the RPD.

An overview of esthetics with removable partial dentures.

A removable partial denture should restore function, phonetics, and esthetics. To assist the clinician in providing a restoration that is as esthetic as possible, despite the limitations of the conventional removable partial denture, this review collates the recommendations scattered among the literature. The review describes the steps involved in providing an esthetic restoration, including diagnosis and treatment planning; surveying; mouth preparation; framework and clasp alloys; clasps; rests; major connectors; minor connectors; prosthetic teeth; and denture base resin and flanges. The esthetic challenges of the Kennedy Class IV removable partial denture are also discussed.

The prevalence of Candida albicans in complete denture and removable partial denture wearers: a comparative study.

In this study, 60 complete denture wearers, 53 removable partial denture wearers and 50 dentate subjects were examined to determine the Candidal carrier state. The influence of local factors such as denture type, smoking habits and sex on Candidal carrier rate were investigated. Wearing complete or removable partial denture was determined as an important factor increasing Candidal carrier rate. Cigarette smoking is another factor which increases Candidal growth in complete denture and removable partial denture wearers. In contrast to denture wearers Candidal carrier rate was considerably less on dentate smokers. Candidal colonization rate was found to be higher on the dorsum of the tongue. This suggests that the tongue is the primary oral reservoir of Candida albicans in the mouth.

Removable partial denture in special clinical conditions.

Controversies concerning the prosthetic treatment through removable or fixed dentures until the age of 18 existed and continue to exist due to the structural instability of the stomatognathic system. In this communication we present a special experience, acquired about the treatment of some clinical situations in which the removable partial denture has been found appropriate with respect to certain features as bone substance loss as a consequence of traumatisms or tumor extirpations, oligodontia, cleft lip and palate. The clinical situations that will be presented refer to a group of 29 patients treated during a period of 10 years in the Department of Prosthetic Dentistry within the Faculty of Stomatology of Iaşi, Romania. Our conclusion is that the children and teenager patients prosthetic therapy differs with respect to the type and etiology of the teeth loss, the affected zone, the stage of the growth and development process of the stomatognathic system, the technological conditions, the patient social conditions, and last but not least, by his affective attitude regarding the teeth loss and the denture type. The removable partial denture for children and teenagers represents, with some exceptions, an emergency or transitory solution until the necessary conditions for other therapeutic stages are fulfilled. Taking into consideration the tissues lability on which it is applied, the removable partial denture requires a rigorous postprosthetic therapy.

Duplicate casts in fabrication of temporary removable partial dentures.

The use of blocked-out duplicate casts in the fabrication of temporary removable partial dentures has been described. Temporary removable partial dentures produced in this controlled manner fit properly and aid in minimizing intraoral damage. Accuracy of fit is assured because all relief is accomplished by block out on the surveyor during the laboratory phase rather than by random grinding of the prosthesis at insertion. In addition, the original cast is salvaged and can be used as a meaningful reference during the finishing process in the laboratory (Fig. 5).

Crown preparations for semiprecision attachment removable partial dentures.

The utilization of intracoronal or extracoronal removable partial denture attachments in conjunction with a fixed retainer applies additional stresses to the structural durability of the fixed retainer and its integrity with the underlying abutment. Therefore, the utilization of this attachment with a fixed retainer requires understanding and diligent application of the basic principles of fixed prosthodontics.The primary objective of prosthodontics must be the preservation and health of the remaining existing tissues and structures: teeth, periodontal tissues, temporomandibular joint, and oral facial muscles. This must be of primary importance as we achieve our goals of (1) eliminating existing pathology, (2) restoring morphology and function, and (3) improving esthetics and thereby heightening self-esteem and the psychological well-being of the individual. These objectives make us sensitive to the considerations we have discussed in preparation design and the tissue management required in the fabrication of fixed retainers.

Fabrication of a new crown and provisional to an existing removable partial denture.

A method of fabricating a new crown to an existing removable partial denture is described. A press-form plastic shell made from the diagnostic cast provides the outer contours for the abutment tooth, while an acrylic resin coping is fabricated on a die to provide accurate internal adaptation. The acrylic resin coping is seated on the prepared abutment. Autopolymerizing acrylic resin is mixed and placed in the plastic shell that is then placed in the mouth over the coping, forming the acrylic resin crown pattern. The removable partial prosthesis is fitted over the crown pattern intraorally. The pattern is transferred back to the die, the margins are refined, and the casting is completed and finished, avoiding reduction of the established contours. The same plastic shell is used with tooth-shaded acrylic resin to construct a provisional crown directly in the mouth. This technique allows the patient to wear the removable partial denture while the laboratory procedures are completed.

Periodontal status of teeth in contact with denture in removable partial denture wearers.

The aims of the study were to determine the periodontal status of the teeth in contact with removable partial dentures (RPDs) and to compare them with other teeth in the opposing arch not related to any prosthesis. The periodontal status was also assessed in relation to the age of the dentures. Four hundred and twenty-seven patients treated with RPDs from 1981 to 1986 were recalled for examination. Prior to prosthetic treatment they were given periodontal treatment and fillings when required. Initially all were given oral hygiene instructions and motivation. They were reviewed regularly only on a short-term basis. Eighteen patients were suitable for the present study comprising of eight males and 10 females whose mean age was 41 years. The RPDs were in use from 1.5 to 8 years (mean 4.6 years). The following parameters were assessed: Plaque index (P1I), Gingival index (GI), loss of attachment (LA) and tooth mobility. The wearing of RPDs resulted in higher P1I, GI and LA compared to the controls and these differences were statistically significant. There was an increased frequency of higher P1I, GI and LA with the increase in denture age. Minor changes in tooth mobility were observed. It was concluded that the wearing of RPDs was detrimental to periodontal health in patients whose oral hygiene was less than adequate.

A provisional removable partial denture for use during construction of an anterior splint bar prosthesis.

A technique for constructing a provisional removable partial denture before and during construction of an anterior splint bar prosthesis is described. The provisional prosthesis is easily adapted to fit the splint bar prosthesis after it is cemented in place. The technique assures that the patient will enjoy the benefits of a well-fitting and esthetic provisional restoration through all phases of construction of the splint bar and the final removable partial denture.

Overlay removable partial dentures for a patient with ectodermal dysplasia: a clinical report.

The orofacial characteristics of ectodermal dysplasia include anodontia or hypodontia, hypoplastic conical teeth, underdevelopment of the alveolar ridges, frontal bossing, a depressed nasal bridge, protuberant lips, and hypotrichosis. Patients with this disease often need complex prosthetic treatment. The options for a definitive treatment plan may include fixed, removable, or implant-supported prostheses, singly or in combination. However, financial constraints and other priorities can prevent patients from choosing the most desirable treatment. This clinical report describes the diagnosis and treatment of ectodermal dysplasia in an 18-year-old man. The treatment included interim removable partial dentures fabricated to establish an acceptable therapeutic occlusal vertical dimension, followed by definitive overlay removable partial dentures and composite restorations.

A comparison of patient's satisfaction between complete and partial removable denture wearers.

OBJECTIVES: The aim of this study was to compare satisfaction between complete denture (CD) and Kennedy Class I removable partial denture (RPD) wearers. MATERIALS AND METHODS: A total of 156 CD and 112 RPD wearers took a part in this study. From the primary group of the examined patients, only those whose RPDs and CDs were assessed as excellent or very good by the dentist, took a part in this study. Patients graded satisfaction of their dentures by using an analogue scale from 1 to 5 (1=unsatisfactory; 5=excellent). RESULTS: Both CD and RPD wearers were mostly satisfied with their dentures (the distribution of the scores of the patients' assessments was skewed towards the highest scores; more than half of the patients scored all the examined variables to the best score category). Complete Denture wearers were significantly more satisfied with chewing, speech and retention of maxillary denture than RPD wearers (P<0.05). Removable partial denture wearers were significantly more satisfied with the retention and the comfort of wearing mandibular denture (P<0.05). There was no significant difference between CD and RPD wearers for general satisfaction with their dentures, aesthetics and comfort of wearing maxillary denture (P>0.05; N.S.). CONCLUSIONS: A majority of CD and RPD wearers were satisfied with the dentures. CD wearers were more satisfied with speech, chewing and retention of maxillary denture, while RPD wearers were more satisfied with the retention and the comfort of wearing mandibular denture. Different groups of denture wearers have to make significant, but different adjustments to wear their dentures successfully.
