Objective: To analyze the associations between posterior tooth loss and masticatory performance, nutrition intake, and nutritional status in the elderly. Material and Methods: A total of 158 subjects aged 60 years and older from Depok, West Java, Indonesia were enrolled in this cross-sectional study. Posterior teeth contacts were assessed and the subjects were divided into two groups based on Eichner Index; group A2-B3 and group B4-C3. The masticatory performance test was conducted using color-changeable chewing gum. A semi-quantitative foodfrequency questionnaire was used to measure nutritional intake in the form of total calories, and the Mini-Nutritional Assessment-Short Form was used to measure nutritional status. Mann Whitney U test was used to determine differences in masticatory performance, nutrition intake, and nutritional status between the two groups. Results: Seventy-four percent of participants were female, and 26% were male. A significant difference in the mean masticatory performance score (p<0.001) was noted between Eichner group A2-B3 (5.66 ± 1.80) and B4-C3 (3.20 ± 1.25). However, no statistically significant difference in nutritional status and calorie intake were found between the two groups (p>0.05). Conclusion: Despite the adequacy of nutrition intake and nutrition status in this population, tooth replacement is necessary to improve masticatory performance in both groups.

Methods:One-hundred and forty removable denture wearers (complete dentures, single complete dentures, and removable partial dentures) participated in this cross-sectional study. Participants were interviewed using a validated Turker's patient's perceptions questionnaire in Indonesia and an OHRQoL questionnaire.Results: There was a significant relationship between patient's satisfaction and OHRQoL (p=0.000). Multivariate analysis showed that the duration of using removable dentures had a significant effect on patient's satisfaction using Turker's patient's perceptions questionnaire. The experience of using removable dentures showed a significant effect on OHRQoL.Conclusion: There was a relationship between patient's satisfaction and their OHRQoL. The duration of using removable dentures affected patient's satisfaction and the experience of using removable dentures affected OHRQoL.

Objective: To evaluate the improvement in masticatory performances two weeks after posterior implant restoration. Material and Methods: Nine patients with missing first and second molars were included in the study. Masticatory performances were evaluated using subjective and objective methods utilizing colorchangeable chewing gum and the visual analog scale (VAS) assessment. The subjects were asked to chew the color-changeable chewing gums before and two weeks after the posterior implant restoration. Their expectations regarding aesthetics and function were verified on the VAS before implant placement. Additionally, the VAS was used for the posttreatment completion rating two weeks after the implant restoration. Results: Significant differences in masticatory performance were noted at baseline (before implant posterior restoration) and two weeks after implant restoration (p<0.05). The posttreatment aesthetic and functional expectations ratings significantly exceeded the expectations (p<0.05). Conclusion: Masticatory performances were improved two weeks after implant restoration. In addition, the significant posttreatment ratings of the patients exceeded their initial expectations. In particular, patients with poor masticatory functions demonstrated significant improvements and satisfaction following implant restoration compared to those with good mastication. These findings indicate that a posterior implant restoration can increase the masticatory performance.

The success of denture treatment depends on the preservation of the remaining alveolar ridge. Preservation of the remaining na-tural teeth can assist in maintaining the integrity of alveolar ridge and proprioceptive ability of the periodontium. The main fo-cus in dentistry today is the maintenance of teeth and the periodontium. This case reports on the rehabilitation of a Cu-sil den-ture in the maxilla. A 70-year-old male patient wants to have denture because he wants to be able to eat and improve his appear-ance. The patient wants to preserve his remaining teeth as much as possible. It is concluded that Cu-sil denture can be an al-ternative treatment for patients who want to replace missing teeth while maintaining the remaining teeth.

Postoperative hemimaxillectomy defects cause the patient to develop conditions such as nasal discharge (hypernasal speech), leakage of fluid in the nasal cavity, and deterioration of masticatory function. Thus, comprehensive rehabilitation is required to improve mastication, speech function and normal orofacial appearance. Successful prosthetic rehabilitation of postoperative hemimaxillectomy defect is a challenging procedure that requires multidisciplina- ry expertise to achieve acceptable esthetics, functional speech and swallowing outcomes. This case report describes clinical steps and laboratory procedures involved in prosthetic rehabilitation of an Aramany Class IV hemimaxillectomy patient with framework obturator.

Abstract. The success of dental implant treatment is determined by the primary stability at placement. One factor that could influence this stability is occlusal loading through provisional restoration. Two types of loading protocols are usually used: immediate and delayed loading. However, some controversies remain about the influence of occlusal loading on implant stability. Therefore, the influence of immediate loading on implant stability must be studied. An animal study was conducted by placing nine dental implants in the mandibular jaw of three Macaca fascicularis. Provisional restorations with various occlusal contacts (no, light, and normal contact) were placed on the implant. The implant stability was measured using the Ostell ISQ three times: immediately (baseline) and at the first and second months after implant placement. The implant stability between implants with no and normal occlusal contact as well as light and normal occlusal contact showed significant differences (p < 0.05) at the first and second months after implant placement. However, no significant increase (p > 0.05) in implant stability was seen at the baseline and the first and second months after implant placement for all occlusal contact groups. Immediate loading influenced the implant stability, and provisional restoration of implant without occlusal contact showed the highest implant stability.
