Background: Dental implant is an optional way to replace edentulous area by surgically placing it into soft tissue or jawbone as a root substitute to hold dentures. Placement of the implant, so that the gingival tissue position will restore aesthetics and function properly. Objective: To discuss the importance of prosthetic planning for implant-supported dentures in the aesthetic zone. Case: Sample case of a patient who had previously subjected to dental surgery for implant placement and placement of a crown on tooth 11. The patient reported poor aesthetics due to gingival retraction and changes on the surface of the ceramic material. After proper planning, the prosthesis is reproduced, with the selection of new components and periodontal surgery using modification techniques for handling soft tissue. Nine months postoperatively, patients had better gingival alignment and reported aesthetic and functional satisfaction. Conclusion:Prosthetic planning to implant-supported dentures in the esthetic zone is very important. Several factors have contributed to the success of the treatment, such as implant position, soft tissue morphology, dental aesthetics, and biomechanics of the prosthetic structure. Complications that can occur after implant pla-cement are gingival recession which will primarily interfere with the esthetics of the anterior teeth so that interventional periodontal surgery is required.

Objective: To analyze the effect of immediate placement of implants with extract from the new bone formation histometically. Material and Methods: In this true-experimental design with randomized post test control group, 9 mongrel dogs weighing 10 to 12 kg were used, which were divided into 3 groups, based on observation time of 14 days, 28 days and 56 days. On the installation of implants ( ∅ 3.5x10 mm) sequentially, the former socket extraction of the lower jaw’s right second premolar tooth in the study sample injected 10% Aloe vera gel extract and left second left premolar tooth without injection of 10% Aloe vera extract. To compare independent groups use the Mann-Whitney test. All analysis were carried out using SPSS version 20. Results: There was an increase in the number of osteoblast cells in both treatment and control groups, but the value of the treatment group was greater. There were significant differences in the number of osteoblast cells between the treatment and control groups 14 days (p=0.019), 28 days: (p=0.018), and 56 days (p=0.009). There were no significant differences in the number of fibroblast cells between the treatment and control groups (p>0.05). But at observations 28 and 56 days, it was showed a significant difference in the number of fibroblast cells between the treatment and control groups (p=0.353 and p=0.024, respectively). Conclusion: Immediate placement of implants with 10% Aloe vera extract gel on extracted socket increases the number of osteoblasts and suppresses the number of osteoclasts and fibroblasts.

Introduction: Denture users with smoking habit often complain about colour changes in their dentures, especially on the base part. Polyamide microcrystalline is a thermoplastic denture base material and does not undergo many colour changes. The purpose of this study was to analyse the effect of filter cigarettes smoke exposure on the colour of polyamide microcrystalline materials. Methods: This study used posttest only control group design — plate-shaped sample with a size of 2 x 2 x 0.5 cm3. Nine samples as controls were immersed without exposure to the cigarette smoke, and 9 samples were immersed in artificial saliva with exposure to the filter cigarette smoke by six cycles, where one cycle was in the form of smoke exposure from one cigarette at 30-minute intervals. Cigarette exposure lasts for 21 days using a smoking simulation tool. Every seven days of exposure, colours were evaluated using a DSLR camera. The photos were then analysed with Adobe™ Photoshop in the CIELab colour space. The results were analysed afterwards by a one-way ANOVA variant test, and advance difference tests were analysed using a Post-Hoc test. Results: There was a significant colour change after exposure (p < 0.05), but the control group did not experience discolouration. The highest rate of colour change occurred in the second week, while in the third week the colour changes still occurred but tend to be stable. Conclusion: Exposure to the filter cigarette smoke changes the colour of polyamide microcrystalline denture base.

Objective: The aim of this study was to determine the correlation between the value of tooth color and skin color in Torajans. Methods: This study was an analytical observational study with a cross-sectional design. This study was conducted in Balusu subdistrict and Saddan subdistrict, Toraja Regency in 2008, using purposive sampling technique based on sex, age, and education characteristics. The sample consisted of 73 torajans, age 15–60 years old, had intact maxillary central incisors, no stains, no calculus, and dental plaque. Data were analyzed with computerized statistical test. Results: This study found that there was a correlation between the value of tooth color and gender in Torajans (p 0.05), and there was no correlation between the value of tooth color and skin color (p > 0.05). Conclusion: There was no correlation between the value of teeth color and skin color in Torajans.

Endosseous dental implants are the treatment of choice for restoring function and reconstructing most edentulousareas of the maxilla and mandible. One of the most common problems in oral implantology is insufficient bone heightbetween the alveolar ridge and the mandible canal, as a result of mandibular atrophy from edentulism. Generally,alveolar bone defects can be reconstructed by either distraction osteogenesis (DO)or autogenous bone grafting(ABG). This paper discussed implant successful rate in DO versus ABG. DO shows a higher successful rate of implantthan ABG with the result more esthetic, lower rate of infection and bone resorption, no pain at donor area, andrelatively uncomplicated.

Many people ignore their oral hygiene and do not use denture after extraction. This may caused by their thinking pattern. Thinking pattern indicates the degree of comprehension to solve a problem. This research aims to find out the thinking pattern of first year students towards edentulous replacement. The questionnaire was filled in by students. The oral cavity state of students who have edentulous was inspected. The study finds that only 3 men and 27 women had edentulous, all of them did not use denture. However, more than 96% of the edentulous and not-edentulous groups said that edentulous need denture, due to aesthetic factor. The reasons for not using denture are, for example, not enough time, not disturbed by the absence of denture, and its cost. It can be concluded that the 2005 batch students of Faculty of Dentistry (FKG) UNHAS had shown a good understanding about edentulous replacement. Their views on the profits and detriments using denture are the main reasons to determine whether they will use denture.
