- Various prosthetic treatment methods are available for addressing tooth loss in the oral cavity, with implant-based prosthetic treatments gaining significant popularity. The criteria for determining the success or failure of dental implants remain a topic of ongoing debate. Over the last 50 years, implant success has been evaluated based on survival rates, radiographic bone loss, mobility, probing depth, the absence of infection in the peri-implant soft tissues, and prosthesis success. Albrektsson et al. and Buser et al. established widely accepted criteria for assessing implant success, focusing on identifying clinical evidence necessary for demonstrating successful osseointegration and implant survival. This study aimed to systematically review and categorize various research findings on the criteria for dental implant success, examine the associated success rates of dental implants, and discuss the most recent standards for determining dental implant success. - COLLAPSE

- Purpose: Endosseous titanium dental implants are widely regarded as the gold standard for replacing missing teeth. Despite the proven osseointegration of titanium implants, particularly those with enhanced surface modifications, concerns remain regarding esthetics, the risk of peri-implantitis, and potential hypersensitivity. Consequently, alternative materials, such as zirconia, have received increasing attention in recent years. This study evaluated the osseointegration parameters of zirconia implants placed in the mandibles of beagle dogs, as a preliminary in vivo evaluation of zirconia dental implants in South Korea.Materials and Methods: Seven 8-month-old beagle dogs underwent premolar extraction followed by placement of implants in the healed mandibular ridges. The following implants were used in this study: six turned-surface titanium implants, six rough-surface titanium implants, and six zirconia implants, following which the implants and surrounding tissues were harvested en bloc for histological analyses. Bone-to-implant contact (BIC) and new bone area (BA) percentages (%) were calculated and compared between the groups. Statistical analyses were conducted using ANOVA, with the significance level set at p < .05.Results: Histological analysis revealed no statistically significant difference in BIC between the rough-surface titanium and zirconia implants, although the turned-surface titanium implants exhibited significantly lower BIC than the other two groups (p < .05). No significant differences were found among the three groups in terms of BA.Conclusion: The results of this study demonstrate that zirconia implants achieve BIC comparable to that of rough-surface titanium implants, suggestive of their potential clinical application. - COLLAPSE

- Retrieval of an Implant Abutment Screw Fractured at the Thread Level: A Case Report

- This case report discusses the approach and considerations involved in retrieving a fractured implant abutment screw. A 69-year-old male patient presented with a dislodged implant prosthesis caused by a fractured abutment screw. The fracture occurred at the most apical portion of the screw, specifically in the threaded region, making its retrieval particularly challenging. The screw was successfully removed using a commercially available retrieval kit. The effectiveness of the kit was attributed to a guide that allowed the retrieval instrument to align precisely with the long axis of the implant. Without such a guide, a risk of damaging the internal threads of the implant fixture exists, potentially leading to the need for implant removal. Therefore, using a retrieval kit with a guide or fabricating a custom-made guide is crucial for preventing implant damage and ensuring proper alignment during the procedure. - COLLAPSE

- Fabrication of Full-arch Implant Prostheses using a One-step Method for Recording the Jaw Relation: A Case Report

- In completely edentulous patients, reference points for determining the occlusal plane and vertical dimension are lacking. Therefore, accurately recording the jaw relation is essential for the fabrication of dentures or implant prostheses. Traditional methods using occlusal rims for bite registration require time for fabrication and intraoral adjustments, leading to patient discomfort with multiple visits. Recently, several methods have been developed to address these limitations by simultaneously obtaining impressions and jaw relation records. The JB Fork (PNUADD Co., Ltd., Busan, Korea) is a one-step jaw-relation recording system that can be integrated with digital protocols for fabrication of dental prostheses. It allows for simultaneous impression-making, verification of the maxillary anterior tooth arrangement, and recording of vertical and horizontal jaw relations, thereby facilitating the transfer of the occlusal plane. This case report aims to present a method for acquiring jaw-relation records using a JB fork and digital scan data. - COLLAPSE

- Here, we describe the successful replantation of a dental implant in a 69-year-old male patient who experienced early implant failure in the right mandibular posterior region (#46) owing to inadequate osseointegration. The patient presented with a narrow alveolar ridge and a class II dehiscence-type defect. A guided bone-regeneration (GBR) procedure using deproteinized bovine bone mineral and an absorbable collagen membrane was performed along with implant placement. Postoperative recovery was uneventful. After 6 weeks of postoperative recovery, healthy soft tissue healing was evident with no signs of infection or bone loss, demonstrating the effectiveness of GBR in managing implant failures with considerable bone defects. - COLLAPSE
