  • When restoring endodontically treated teeth is the mismatch between fiber post size and post space diameter, the resin cement layer is excessively thick in post space and voids are likely to form in it, thus predisposing to de-bonding. The method to overcome this problem is to reline the fiber post with composite resin. This individual anatomic post improves the adaptation of post to root walls and decreases the resin cement thickness. The purpose of this in vivo study was to evaluate the push-out bond strength of fiber post according to relining procedure and luting agents type used for simplicity of clinical procedure. Forty-two extracted teeth were divides into six groups.(n=7) A1: relined fiber post cemented with Luxacore/all-bons 2, A2: non-relined fiber post cemented with Luxacore/all-bond2, B1: relinind fiber post cemented with Calibra/XP-bond, B2: non-relined fiber post cemented with Calibra/XP-bond, C1: relined fiber post cemented with RelyX Unicem, C2: non-relined fiber post cemented with RelyX Unicem Push-out bond strength was affected by interaction between relining procedure and luting agent type. Relined fiber post presented higher push-out bond strength value than non-relined fiber post and statically significant differences(p<0.05) Cementation with RelyX Unicem showed significantly higher bond strength than other luting agents(p<0.05).

  • This study compared the marginal bone loss around dental implants that were placed in the canine areas of the mandibles and finded the survival rate of the implants, marginal bone loss around implants and prosthetic complications in 20 patients treated with overdentures retained with Locator attachments. Implants placed in this study showed a 95% survival rate and the average marginal bone loss was 1.21 mm($SD{\pm}0.60mm$) in 94.3 weeks of functional loading. Implant-retained overdentures had various prosthetic complications such as male change, metal cap loosening, Locator attachment loosening, denture teeth change, relining and denture fracture. Implant-retained overdentures using two implants and Locator attachments in the edentulous mandibles is considered as a stable way for long terms because of minimal invasive operation, simple prosthetic process and easy repair.

  • Impression taking procedure is very important for support, retention and stability of denture, and it affects the success of denture in completely edentulous patients. Various materials and methods have been used for impression taking in complete denture, while dynamic impression method is more physiological and functional method than the others. We had satisfying results with fabrication and relining of dentures after taking impression in the most physiological condition with recovery of deformed soft tissue by dynamic impression method using Coe-comfort$^{(R)}$ (GC America, IL, USA), tissue conditioner, in edentulous patients in this case report.

  • Purpose: This study compared the marginal bone loss around dental implant that were placed in the canine areas of the mandibles and finded the survival rate of implants, marginal bone loss around implants and prosthetic complications in 10 patients treated with overdentures retained with Locator attachments. Materials and methods: Ten patients who had received implant retained overdentures in the mandibules using two implants and Locator attachments at Daegu Catholic University Medical Center from 2004 to 2010 were included in this study. Evaluations of the survival rate of implants, marginal bone loss and prosthetic complications were performed. Results: Implants placed in this study showed a 100% survival rate and the average annual bone loss was 1.03 mm ${\pm}$ 0.20 mm in the first year. The patients have verbally indicated that they are comfortable and that their overdentures function well. But, implant retained overdentures had various prosthetic complications such as male change, relining, rebasing and denture fracture. Conclusion: Implant retained overdentures using two implant and Locator attachments in the fully edentulous mandibles is considered as a stable way for long terms because of minimal invasive operation, simple prosthetic process and easy repair.
