The extent and direction of movement of removable partial dentures during function are influenced by the nature of supporting structures and the design of the prosthesis since forces are transmitted to abutment teeth by rest, guide planes, and direct retainers during functional movements. Because of the lack of tooth support distally, the denture base will have tissueward underfunction proportionate to the quality (displaceability) of the supporting soft tissue, the accuracy of the denture base, and the total occlusal load applied. The movement of the base under function determines the occlusal efficiency of the partial denture and the degree to which the abutment teeth are subjected to torque and tipping stresses.The purpose of this study is to know the functional load exerts with RPI and RPL direct retainer in bilateral distal extension. This study is a laboratory experiment employing samples of 5 frames using RPI and 5 frames using RPL direct retainer design. Testing was conducted by Vishay Teaching Polariscope type 080. The result was noted and analyzed statistically using ANOVA.The result of this study indicates that F calculation value for frame with RPI and RPL direct retainer design is 5,35 and 6,11 Mpa; F calculation for the occlusal load distribution on first premolar and edentulous area is 276,90 Mpa and 171,53 Mpa; F calculation for occlusal load distribution on first premolar and edentulous area employing RPI and RPL direct retainer design is 9,17 and 11,96 Mpa. This statistical calculation shows that there is a significant difference between RPI and RPL direct retainer design, the occlusal load concentrated at edentulous area either RPI or RPL direct retainer, and the occlusal load distribution between the first premolar and edentulous area are more uniform on RPI direct retainer design.

It should come as no surprise that tooth loss and age are linked. It has been documented that there is a specific tooth loss relationship with increasing age because some teeth are retained longer than others. There is an interarch difference in tooth loss, with the maxillary tooth loss beforemandibular teeth. There is also an intraarch difference with posterior teeth loss before anterior teeth.Frequently, the last remaining teeth in the mouth are the mandibular anterior teeth, sometimes accompanied by compromised conditions, and it is a common finding to see an edentulous maxilla opposing mandibular anterior teeth2. The swing-lock removable partial denture concept offers a wayof maximizing the retention and stability of the removable partial denture and may be very useful in restoring the extremely compromised dentition4. The retentive and stability denture enhance the quality of life by serving esthetic, mastication, and phonetic functions.Keywords: swing-lock removable partial denture, esthetic, mastication, and phonetic function.

Heat-cured acrylic denture base-plate may act as reservoir for Streptococcus mutans (all species name must be in italics) colonies, this condition may lead to denture stomatitis. One of denture cleansing method that frequently used is by immersion (of what?) in oxygenizing denture cleansers that has several disadvantages such as high cost and biocompatibility issue regarding chemical synthetic component of the solution. Chitosan is a natural compound that has antibacterial nature. The most commonly percentage of chitosan used for biomedical purposes is 2%. The objective of this study is to evaluate the antimicrobial effectivity of chitosan 2% on acrylic heat-cured plates and compare it with oxygenizing denture cleansers. Aquadest was used as control. Fifteen acrylic heat-cured plates (10 x10 x 2 mm) immersed in Streptococcus mutans suspensions at temperature 37Â°C for 48 hours of 3 different solutions. The solutions were vortexed and put into (Brain Heart Infusion Agar) medium. Streptococcus mutans colonies were counted manually. The result shows, that Streptococcus mutans colonies on aquadest group was 269.75 CFU/plate, followed by oxygenizing denture cleanser with 11 CFU/plate), and chitosan 2% group with 0.4 CFU/plate, respectively. Data were analysed with Kruskal-Wallis non-parametric test followed by Mann-Whitney test shows of p=0.012 (p<0.05). There were no statistically significant different of antimicrobial activity between chitosan 2% and oxygenizing denture cleanser. The result demonstrated that chitosan 2% solution was more effective to prohibit the growth of Streptococcus mutans colonies on acrylic heat cured plates, however a statistically significant difference between the two groups was not observed.
