The aim of our study was to evaluate the deformation resistance of two palatal plate type connectors of removable partial dentures and to make a comparison between the reduced palatal plates and the large ones, in terms of bending resistance during function. We tested 10 maxillary class I Kennedy removable partial dentures made for real clinical cases and duplicated their connectors, 5 of each type. A Universal Loading Machine was used to apply a bilateral progressive force to the PM2-M1 area until the samples bended, recording the force value at which the first change occurred. The results were analyzed using the ANOVA method. For the reduced palatal plate group, the minimum bending force value was 1584 N, the maximum bending force value being 2920 N. For the large palatal plate group, the minimum bending force value was 3150 N, the maximum value being 3380 N. Statistical analysis of data using the ANOVA method shows that the results are statistically relevant, with a p value of 0,001031 (p[0,05). The results showed that decreasing the width of the palatal plate can have a significant effect on the deformation resistance of the major connector and can affect its rigidity; in clinical practice, these results can help dentists to use alternative appropriate design methods of increasing the rigidity of reduced palatal plates, in order to protect both the remaining structures and the acrylic components of the dentures during the years of its functioning.

Bucco-sinus communications are common incidences and may be associated with posterior superior tooth extraction. In large maxillary losses, repairing prostheses have a categorical or essential indication. Thus, the objective of this study is to report a clinical case of prosthetic rehabilitation using a removable partial denture (RPD) due to absence of teeth in the posterior maxilla region resulting from a dento-alveolar fracture as consequence of traumatic injury. A 21-year-old male patient attended the dental clinic at Nilton Lins University, reporting masticatory failure, discomfort and sensitivity when eating cold foods in the right upper molars region. After clinical and radiographic examination, it was observed that in addition to the absence of teeth 16, 17 and 18, there was an extensive bone loss in the right posterior hemiarch, with surgically sealed bucosinusal communication. As treatment plan, rehabilitation using a removable partial prosthesis modified and adapted to the acquired defect was proposed. In the consultations, the stages of study model manufacturing, assemble in a semi-adjustable articulator and delineation. The modification of the metallic frame consisted of a larger connector, like a wide palatal plate 10 mm long without relief on the palate, complemented by indirect twinned clamps and direct “T” type on tooth 15. The case was concluded with the steps of metal frame test, teeth assembly, teeth testing, acrylization and installation. The rehabilitation treatment by means of restorative PPR was satisfactory, as it was observed that after its installation, the patient showed extreme satisfaction with the result obtained, with an explicit improvement in chewing and swallowing.

BACKGROUND: Patient’s satisfaction and the preservation of abutments is the most important outcomes that the clinician seeks during fabrication of any dental treatment, especially when it is concerned with removable prosthodontic rehabilitation. AIM: The present study evaluates three different Removable Partial Denture (RPD) types restoring mandibular class II modification I edentulous cases with regards to patient’s satisfaction and abutments survival. METHODS: Forty-two partially edentulous patients were divided into three groups (Group I rehabilitated with Vitallium RPD, Group II rehabilitated with Vitallium RPD where the modification area restored with the surveyed bridge, Group III rehabilitated with Thermopress RPD). The patients were followed up for twenty-four months. Using a questionnaire, prosthodontic maintenance required was documented at the delivery and after 3 months. RESULTS: There was a significant difference regarding patient satisfaction for group III (P-value <0.05) while for groups I and II there was a non-significant difference (P-value >0.05). Regarding the survival rate, there was a non-significant difference between the three groups (P-value >0.05) at the end of twenty-four months of follow up. CONCLUSION: Patient satisfaction and abutment survival were better with Thermopress RPD than conventional Vitallium RPD or Vitallium RPD with a surveyed bridge restoring the modification area. Although a non-statistically significant difference was found in the survival rate of abutments between groups, a clinically important result was revealed as no abutments failures were reported in the Thermopress group.

Abstract: Removable partial denture is indicated to patients who lose some of their original teeth. The use of denture plays an important role in the recovery of masticatory system lost or disturbed due to tooth loss. This study was aimed to obtain the effectiveness of the use of removable partial dentures on the function of mastication. This was a quasi experimental study with one group pre and post test design. Population consisted of the community using removable dentures at Desa Pinasungkulan Modoinding, based on the prevalence of 879 denture users. There were 16 denture users as samples obtained by using purposive sampling method. We used questionnaire that had been tested for validity and reliability and the Wilcoxon test for data analysis. The results showed that the score of the effectiveness of mastication without using dentures was 207, categorized as 'less effective', meanwhile, the score of with using denture was 293, categorized as 'effective'. The Wilcoxon test resulted in a p-value of 0.004 which meant that there was a difference in masticatory function between using denture and without using denture.

Introduction: These days, individuals seem to have more expectations regarding their dental health compared to the past. There are various treatment options available for the replacement of missing teeth and associated structures, which include removable prosthesis, fixed prosthesis, and implant supported prosthesis. Most of the patients require aesthetics and functional comforts with prosthodontic treatment and it can be easily achieved with dental implants and tooth coloured restorations and prostheses. Aim: To assess the trends, awareness, and attitude of patients towards replacement of missing teeth in western region of Saudi Arabia. Materials and Methods: A cross‑sectional study was conducted among the 20‑60 years aged population of Western region of Saudi Arabia from 1st December 2018 to 1st March 2019. A questionnaire consisting of 11 close ended, pre‑tested questions was developed to determine patients’ attitude and need with regard to their dental prosthesis. The data were tabulated and analysed using Statistical Package for the Social Sciences (SPSS) version 21. Chi‑square test was used to assess the attitude and awareness among the patients towards replacement of missing teeth. The p‑value of less than 0.05 was considered statistically significant. Results: The study included 350 patients; 162 males (46.3%) and 188 females (53.7%). Among the participants, 233 (66.60%) of them desired fixed treatment and 115 (33.40%) of them desired removable treatment. Treatment options explained by clinicians were as follows: 67 (19.1%) were suitable for Fixed Partial Denture (FPD)/dental Implant, 11 (3.1%) suitable for FPD, Removable Partial Denture (RPD) and dental Implant and 272(77.7%) of them suitable for RPD and dental Implant. A total of 67 (19.1%) of them opted for FPD, 115 (32.9%) of them opted for RPD and 168 (48.0%) of them opted for dental Implant. Conclusion: Awareness and attitude of the participants towards prosthodontics treatment were mostly high. Majority of the participants wanted to replace missing teeth for mastication and aesthetics and had favourable knowledge and attitude towards implant as a mode of treatment for replacement of missing teeth. Participants preferred fixed treatment over removable.

(1) Background: The degree of satisfaction with dental treatment varies among patients, and the discrepancy may exist between the patient’s subjective evaluation and the objective assessment. Further, the optimal methods for increasing patient satisfaction with mastication remain unclear. This study aimed to identify factors affecting masticatory satisfaction in patients with removable partial dentures. (2) Methods: A total of 132 participants (71.0 ± 9.0 years) were included. Masticatory satisfaction was assessed on a visual analog scale. An oral health survey was conducted to assess the number of functional teeth, missing tooth classification: Kennedy classification, occlusal support: Eichner classification, and removable partial dentures wearing jaw. Objective masticatory performance was assessed using gummy jelly, while subjective masticatory ability was assessed using food acceptance status and oral health-related quality of life. The associations of these factors with masticatory satisfaction were assessed. (3) Results: Masticatory satisfaction among removable partial denture wearers was not significantly associated with gender, age, denture wearing jaw, Kennedy classification, and occlusal support. The degree of masticatory satisfaction was significantly greater with higher levels of masticatory function: masticatory performance, food acceptance score, and OHIP-14 score. The OHIP-14 score was the only significant explanatory variable for masticatory satisfaction in the multiple regression analysis; the strongest associations were with the “psychological discomfort” and “physical disability” subscales (p = 0.02 and p = 0.005, respectively). (4) Conclusions: Masticatory satisfaction among removable partial denture wearers was strongly associated with oral health-related quality of life, in which the ability to eat meals comfortably with removable partial dentures is the most important determinant of masticatory satisfaction.

Background: Anterior cervical discectomy and fusion surgery is a common procedure for degenerative cervical spine. This describes allospacer and implant-related outcomes, comparing medium plate–low screw angle and short plate–high screw angle techniques. Methods: From January 2016 to June 2019, 79 patients who underwent ACDF were prospectively enrolled. Patients were divided, depending on the plate–screw system used: medium plate–low screw angle (12.3 ± 2.5 to 13.2 ± 3.2 degrees), and short plate–high screw angle (22.8 ± 5.3 to 23.3 ± 4.7 degrees). Subsidence, ALOD, and sagittal cervical balance were analyzed using lateral cervical X-rays. NDI and VAS scores were also evaluated. Results: Age for medium plate–low-angled screw group is 58.0 ± 11.3 years, and 55.3 ± 12.0 in the short plate–high-angled screw group (p-value = 0.313). Groups were comparable in mean NDI (p-value = 0.347), VAS (p-value = 0.156), C2–C7 SVA, (p-value = 0.981), and lordosis angle (p-value = 0.836) at 1-year post-surgery. Subsidence was higher in the medium plate–low-angled screw than in the short plate–high-angled screw (25% and 8.5%, respectively, p-value = 0.045). ALOD is also more common in the medium plate group (p-value = 0.045). Conclusion: Use of a short plate and insertion of high-angled screws (more than 20 degrees) has less chance of subsidence and occurrence of ALOD than the traditional technique of using medium plate and low angle.
