Introduction. Various mobile devices are used in the therapy of unilateral free-end saddle. Unilateral dentures with precise connectivity elements are not used frequently. In this paper the problem of applying and functionality of unilateral freeend saddle denture without major connector was taken into consideration. Objective. The aim was to analyze and compare a unilateral RPD (removable partial denture) and a classical RPD by calculating and analyzing stresses under different loads. Methods. 3D models of unilateral removable partial denture and classical removable partial denture with casted clasps were made by using computer program CATIA V5 (abutment teeth, canine and first premolar, with crowns and abutment tissues were also made). The models were built in full-scale. Stress analyses for both models were performed by applying a force of 300 N on the second premolar, a force of 500 N on the first molar and a force of 700 N on the second molar. Results. The Fault Model Extractor (FME) analysis and calculation showed the complete behavior of unilateral removable partial denture and abutments (canine and first premolar), as well as the behavior of RPD under identical loading conditions. Applied forces with extreme values caused high stress levels on both models and their abutments within physiological limits. Conclusion. Having analyzed stresses under same conditions, we concluded that the unilateral RPD and classical RPD have similar physiological values.

Objective: To evaluate and compare the effect of implant supported versus implant retained removable partial denture restoring Kennedy's class I cases on the supporting structures by measuring modified gingival index and probing depth for abutment teeth and implants. Subjects and Methods: Twelve patients; who had Kennedy class I mandibular partially edentulous ridge extending distal to the first or second premolar,   were selected from the outpatient clinic, Prosthodontics Department, Faculty of Dentistry, Minia University. The patients were classified into two equal groups; according to the implant superstructures either dome shaped abutment or ball and socket attachment.  Each Patient of both groups had two implants in second molar position (one in each side) and received removable partial denture of the same design. Patients were followed up for one year clinically. Group I: Six patients received RPD supported by dome shaped short abutments.  Group II six patients received RPD retained by ball and socket attachments. Results: Results revealed that, there was no statistically significant difference between the two groups regarding modified gingival index and probing depth around the abutment teeth and implant abutment. Conclusion:  The use of dome shaped abutment or ball and O-ring attachment have the same effect on gingival index and probing depth around natural abutments and implants in Kennedy class I mandibular situations.

AIM: The aim of this study is to evaluate two different designs in mandibular bilateral free end saddle cases with the use of osseointegrated implants. The designs evaluated were OT-strategy extracoronal attachment and bar attachment. Radiographic evaluation was carried out for implants and natural abutment in terms of bone density. MATERIALS AND METHODS: This study was conducted on 10 patients with bilateral distal extension area with missing molars bilaterally; the patients were divided into two groups after implant insertion on the second molar area. Group I: Patients received extracoronal attachment distal to the last natural abutment teeth with the construction of metallic removable partial denture (RPD). Group II: Patients received bar attachment with the construction of metallic RPD. Both groups have the maxillary arch edentulous with the construction of complete maxillary dentures within our study. Radiographic evaluation for bone density was done for both groups at the time of prosthesis insertion, 3, 6, and 9 months later. A comparison between the two groups regarding each follow-up period was performed by an independent t-test. RESULTS: Although there were some differences between both designs in the 1st-time intervals, generally, there were no significant differences between the two designs all over the 3-time intervals. CONCLUSION: From the results of this study, it was concluded that: Although there were no significant differences between both designs, bar-attachment showed better results which should be confirmed with more future researches.

In the case of losing many teeth and the residual teeth have short clinical crown, design of the denture may hybriddenture. Hybrid denture is a removable partial denture with metal frame which have retention in the form ofprecision attachment. In short clinical crown, placement of crowns and the use of traction can be a problem,because there is no or lack of retention. In the manufacture of hybrid denture with precision attachment retention,using abutment with short clinical crowns is contraindicated. But in some literatures mentioned that the rest of theclinical crown height of not less than 2 mm can still be used as an abutment, but the abutments must be modified,such as making a longer preparation towards cervical edge. In several studies and literature, it is mentioned that toimprove the retention of the crown, the axial wall of abutment must be 4-6°. This article is aimed to report the clinical success of using the hybrid denture on abutment teeth which have short clinical crowns in a patient woman

Oral rehabilitation with free-end removable partial denture (RPD) is one of the major challenges in prosthodontic dentistry. The absence of a distal abutment produces undesirable RPD movement during masticatory function due to the high resilience of the residual ridge, which limits the denture efficiency and may damage the abutment teeth and bone over time. The advent of dental implants made possible to substitute the missing teeth with fixed implant-supported dentures as the first choice treatment to overcome such inconveniences. However, this indication may not be suitable for all patients due to financial, anatomical or systemic health conditions. Nevertheless it is possible to improve free extension RPD by using implants in the posterior edentulous ridge to achieve biological, biomechanical, physiological and social benefits. This article aims to present a case report on oral rehabilitation in which a RPD was made combined with an implant for posterior support in a sizeable edentulous ridge. The patient appreciated the retention improvement and the aesthetic result. The combination of a RPD with a posterior implant is an alternative treatment for cases in which implant-supported fixed prosthesis is not indicated, reducing the displacement and minimizing the limitations of the free-end devices.

And Function

The selective laser melting technology is an additive digital method that permits producing metal frameworks for removable partial dentures. The existing literature has compared this technique with the classic technique in terms of precision, quality of fit, and function. This work describes a clinical case of a metal framework produced by the selective laser melting technique in a patient rehabilitated with a removable partial denture. No adjustments were required when the metal framework was inserted, showing good adaptation and stability to the abutment teeth and surrounding tissues. Further studies are necessary for a significant assessment of this technique’s clinical applicability.

<p class="AbstractContent">Restoring occlusal plane and occlusal vertical dimension (OVD) in patient with existing indirect restorations who must wear removable prostheses may be a challenge to the dental operator. Onlay removable partial dentures (RPD) are used to re-establish the occlusion in conjunction to replace missing teeth without having to remove the existing indirect restoration. This case report described prosthetic rehabilitation with onlay RPD in patients who were partially edentulous and has reduced OVD. The treatment involved a set of provisional RPD to re-establish the OVD, as well as to evaluate the function, esthetic and speech of the patient, followed by definitive onlay RPD. The mandibular onlay RPD was used to provide stable occlusion and to correct the uneven occlusal surface on the abutment teeth. This treatment able to improve patient’s chewing function through a simple removable prosthesis and conservative on the existing restorations.</p>
