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.

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 5-year longitudinal study of cantilevered fixed partial dentures compared with removable partial dentures in a geriatric population.

Prosthesis function and dental conditions were observed for 5 years in 27 elderly patients treated with mandibular cantilevered fixed partial dentures (FPDs) and in 26 elderly patients treated with distal-extension removal partial dentures (RPDs). All patients were treated with a complete upper denture. The patients were assigned randomly into two treatment groups that had the same composition with regard to sex, age, and distribution of teeth. The patients were under supervised oral hygiene and prosthodontic care. Clinical examination of prostheses, masticatory system, periodontal status, and caries was carried out yearly. Oral hygiene was good, and the periodontal status was maintained in both groups. Caries was observed six times more frequently in the RPD group than in the group with fixed restorations, however. Occlusal and functional conditions deteriorated in the RPD group only. Eight of 42 fixed partial dentures (19%) failed; of these, six were recemented with composite resin. Generally the need for dental and prosthetic follow-up treatment was more pronounced in the RPD group than in the FPD group.

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.

Investing procedures for immediate laboratory remounting of removable partial dentures.

Remounting removable partial dentures in the laboratory after deflasking and before clinical placement has several advantages. This modified investment procedure makes it easy to remount partial dentures after processing. Preliminary adjustments of laboratory errors and inaccuracies caused by dimensional changes in heart processing of acrylic resin may be made before the appointment with the patient.

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.

Occlusal plane modification of an existing maxillary complete denture prior to removable partial denture construction: a case report.

Success in fabricating removable partial dentures, Kennedy Class I and Class II in particular, is highly dependent on proper orientation of the occlusal plane. The closer to the ideal, the better the prosthesis will function and provide proper esthetics and phonetics. This case report presents the diagnosis and occlusal modification of an existing maxillary complete denture to improve the patient's masticatory function with the fabrication of a removable partial denture.

Correction of prognathism with fixed and removable partial dentures.

Prognathism in those patients for whom surgical orthodontic procedures are contraindicated can be successfully treated by the use of fixed and removable partial denture prosthodontics. Careful neuromuscular evaluation of the patient is necessary for the success of the treatment rendered. The nonsurgical treatment of prognathism by this method was described.

Porcelain-fused-to-metal crowns as replacements for denture teeth in removable partial denture construction.

A procedure has been described for using porcelain-fused-to-metal crowns in place of denture teeth on a removable partial denture. Improved esthetic results are achieved when replacement denture teeth are made simultaneously with, and visually match, adjacent tooth crowns. This procedure provides a superior treatment result, particularly where multiple unilateral anterior teeth are lost and a removable partial denture is indicated.
