Abstract

Background: Tooth loss can be replaced with dentures, implant dentures are one of the treatment options that can be chosen because they have a comfort, function, and aesthetics. This case report will explain the procedures for the loss of 1 unit mandibular tooth subcrestally. First year after implant placement, there will be a decrease bone in the implant area 1-1,5 mm and followed by normal decrease of 0.1-0.2 mm each year. Case Report: The patient complained of missing lower left tooth and wanted to have permanent prosthesis. The patient had no systemic disorders and allergies. The patient planned to do  implant treatment on tooth 37. There are 2 stages of surgery. Stage one involved the implant placement. Second stage the healing abutment installed. The prosthetic stage monolithic zirconia screw and cement retained prosthesis was used. Conclusion: Dental implant treatment with subcrestal placement is considered to have good results in the long term. In the first year after treatment, the alveolar bone will experience a decrease of 1-1.5 mm in the implant area. In this case, implant placement 1 mm below the bone level will reduce the risk of implant exposure in the long term

Abstract

Alveolar socket preservation (ASP) requires an ideal barrier membrane that provides anti-bacterial activity, water contact angle (WCA) and swelling behavior to support bone regeneration. This study evaluated these characteristics in a Polyvinyl Alcohol-Collagen-Hydroxyapatite composite membranes derived from the scales of Lates calcarifer.L. The PVA-Col-HA CM was produced from the scales of Lates calcarifer through mixing, homogenization, casting, and drying and then divided into three groups: non-irradiated, 15 kGy irradiation, and 25 kGy irradiation. Antibacterial activity was assessed by disk-diffusion test and inhibition zone diameters were measured. Water contact angle was determined using a contact angle goniometer on both membrane surfaces. Swelling behavior was evaluated by immersing samples in phosphate-buffered saline for 60 minutes, followed by periodic weighing and calculation using a swelling formula. The anti-bacterial activity test showed a larger zone of inhibition in the 25 kGy group by 2mm on Escherichia coli and Staphylococcus aureus. One-way ANOVA test of WCA values showed significant differences (p < 0.05) among groups, with the 25 kGy group exhibiting the highest hydrophilicity. Analysis of swelling behavior using ANOVA and Kruskal-wallis test showed no significant differences (p > 0.05) among groups, but the linear graph shows that the 25kGy group displayed the lowest and most stable swelling profile. These findings suggest that the PVA-Col-HA CM exhibited favorable anti-bacterial activity, WCA, and swelling behavior, with optimal performance observed in the 25 kGy irradiation group.
