Advantages of metal framework partial denture than conventional denture base include power and can be made asthin as possible. But the success is influenced by clasp design. Many things to be considered in positioning theclasp, therefore knowledge of the diagnosis, indications, contraindications, and biomechanical properties of themetal that used to be important in the treatment. This study aimed to determine the retentive strength of akers andback action for the abutment first molar and first premolar and the upper and lower clasp design is mostappropriate for the abutment. Research using 8 samples I (gypsum base with natural teeth) and 8 samples II(gypsum base metal crown) maxillary and mandibulary first premolar and first molar with a depth of 0.25 mmundercut. Sample II soaked in artificial saliva, surveyed and was prepared for a rest seat. Akers and back actionclasp were inserted on a metal crown and measured their retentive strength with Instron UTM. The results obtainedindicate the highest retentive strength metal abutment crown molar and premolar with Akers compared to backaction. Highest retentive strength on metal molar abutment crowns with the Akers and upper premolars with metalcrowns back action. There are significant differences between the groups retentive strenth of clasp design. It wasconcluded that best retentive force on the upper molars with akers and upper premolars with Akers.

Scientific Achievements

Purpose: The purpose of this paper is to analyse attempts at improving the bond between acrylic artificial teeth and the denture base plate - considered in the context of single incisors in framework denture. Design/methodology/approach: It is a review article focusing on the analysis of state of the art in the field of the bond between the polymerised acrylic (teeth) and the polymerising acrylic resin during the production of denture (denture plate). Previous works regard the issue of individual incisor teeth (both upper and lower) breaking off from the metal partial denture. Findings: The bond between artificial acrylic teeth and the acrylic denture plate of the prosthesis was discussed. Ways of improving this bond were also presented. Although researchers and companies offer many methods for improving this bond, none of them refer directly to the issue discussed in this article. In conclusion- the hitherto scientific achievements work well in the case of acrylic prostheses without a metal frame, which constitutes an obstacle for achieving the effect required. In this work, it is suggested that further research would not only develop and provide more detail on the issue of the bond between artificial teeth and the denture plate, but also solve the problem appearing in cases of metal partial denture. Originality/value: This article shows a significant problem that hasn’t been discussed in detail in the past.

Metal framework denture is needed in patient with tooth loss accompanied by the presence of periodontal disease inthe remaining tooth is needed. This denture primarily maintains the existing teeth post periodontal treatment. Theuse of metal framework in this case can help to prevent tooth movement and maintain tooth position afterperiodontal treatment. Therefore, the success of the treatment can be achieved because the metal characteristic ismore rigid when compared to other dental materials. This paper discusses the use of frame denture in patient afterperiodontal treatment on the remaining teeth in lower arch. It can be concluded that removable denture with metalframe combined with splint must be done on mobile teeth, to decrease mobile teeth and to preventincreasing of periodontal tissue damage after periodontal treatment.

Abstract The Kennedy Class I removable partial denture (RPD) can cause stress to supporting hard and soft tissues and may lead to harmful effects. The purpose of this study is to investigate the pattern of these stresses in three different positions before and following a relining procedure. Ten patients, five males and five females, with a lower distal extension RPD and an opposing upper class III type RPD were selected for this study. Strain gauges together with a strain gauge indicator were used to study the pattern of stresses in three selected positions. Some changes were significantly different at the site of the denture base and at the metal frame near the direct retainer. After relining, the stresses were shared partially by the abutments and partially by the tissues. Maximum stresses were reported during swallowing. No significant difference was noticed between males and females. Citation Al-Ghannam NA, Fahmi FM.

<p><strong>Objective:</strong> This study aimed to evaluate the retention of acetate resin clasp as when compared to metal clasp. <strong>Material and methods:</strong> For this purpose, we constructed 10 conventional Co-Cr metal clasps (Ackers) and 20 acetate resin clasps. The acetate resin clasps had the opposition, support and retaining arms made of Co-Cr. Of the 20 esthetic clasps, 10 had the thickness of the retention arm decreased to make it more esthetic. The initial retentive force of the specimens was tested in a universal testing machine through tensile test.  After that, the specimens were subjected to 7,000 cycles, each one, in an adapted machine, immersed into artificial saliva, for 36 months of simulated clinical use of a removable partial denture. Data were tabulated for statistical analysis of the retention effectiveness. <strong>Results:</strong> After cycling, 3-mm-thick and 2-mm-thick acetate resin clasps lost more retention than metal clasps. The material type (p=0.0000) and cycling (p=0.0039) showed a significant effect, but the material/cycling interaction (p=0.1436) did not. <strong>Conclusions:</strong> Therefore, esthetic clasps presented retention force lower than that of metal clasps. Notwithstanding, the esthetic clasps can be used in clinical cases requiring minimum retention.</p><p> </p><p><strong>Keywords</strong></p><p>Removable partial denture; Esthetic clasp; Metal clasp.</p>

Introduction. Complete denture reinforced with metal bases is fabricated in cases of fracture risk as well as in selected patients with neuromuscular disorders. The aim of this report was to present different designs of metal framework for complete denture and their advantages in the treatment of edentulous patients. Material and Methods. The study included 116 edentulous patients who received complete dentures. The respondents were divided into two groups according to the type of denture used. Thirty one patients were rehabilitated with complete dentures reinforced with metal base, whereas 85 patients received conventional complete acrylic dentures. Metal bases were fabricated using Co-Cr-Mo alloy. Two designs different in regards to the vibrating line were fabricated: metal frame extended to the vibrating line and acrylic resin extended to the vibrating line. After investing and casting, metal bases were electropolished. Subsequent processes of arranging artificial teeth, waxing, flasking and finishing completed the fabrication process of dentures. Results. Denture base fractures were prevented in majority of patients. The design of upper denture where metal frame was extended to the vibrating line and metal base with elongation over the convex edentulous ridge in lower jaw were the most favored and successful in prosthetic rehabilitation of experimental group of edentulous patients. There was no need for rebasing of complete dentures reinforced with metal base. Conclusion. Complete denture reinforced with metal base presents a favorable design for rehabilitation of edentulous patients with well pronounced edentulous ridges and low tendency to resorption.

Immediate complete denture (ICD) is a mucosa-supported prosthesis manufactured before the removal of natural teeth and installed soon after their extraction. This paper aims to describe a clinical case of oral rehabilitation with upper ICD and lower removable partial denture (RPD). A 57-year-old female patient sought treatment with dissatisfaction with her aesthetics and mobility of the upper teeth. After anamnesis, intra and extra-oral examinations, radiographic examination and analysis of study models mounted on a semi-adjustable articulator, periodontal pockets were found in the upper teeth and extensive bone loss. So, upper tooth extraction, superior ICD and lower RPD were indicated as treatment. For ICD preparation, anatomical and functional moldings were made, made up of orientation and intermaxillary relationship plans for the assembly of the semi-djustable articulator models. The remaining upper teeth were removed from the model for assembly of the artificial teeth and the ICD was polymerized and polished. The lower RPD was made following the standard steps. After dentures manufacturing, the surgery for upper tooth extraction was performed and prostheses installed immediately after surgery. The results demonstrated that the performed treatment provided aesthetic, phonetic, and functional restoration to the patient avoiding her to undergo a period of edentulism. It was concluded that ICD is a good indication for prosthetic rehabilitation of patients with advanced periodontitis, whose planning is the exodontia of all the teeth of an arch.

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
