OPEN ACCESS Sinus lif t procedure is f requently required for the maxillary molar implant placement. Previous studies have demonstrated alveolar ridge preservation (ARP) can maintain the dimensions of ridge height and width. However, there is a lack of studies which evaluated the effect of ARP to avoid sinus lif t procedure. Purpose of this study is to describe a method reducing the need of sinus lif t surgery by ARP in maxillary molar areas and to assess the feasibility clinically, radiologically and histologically. Ten maxillary molars in ten patients had severe vertical bone resorption with minimal residual bone height. They were considered having the high possibility of the necessity of sinus lif t procedure for dental implant af ter the extraction. After extraction, open healing ARP with deproteinized bovine bone mineral mixed with 10% collagen and resorbable collagen membranes was performed. After sufficient healing, dental implants were placed, and evaluated clinically and radiologically. Histological observation was conducted just before the implantation in one patient. Implants were successfully placed without sinus lift in all ten cases. All the implants were restored with no sign of complications, and patients are now in a close follow-up up to 20 months postloading. Histological observation showed minimal inflammatory reaction and newly formed bone was substantially noted. The ARP technique has successfully avoided the sinus lif t surgeries. It appears that this procedure may improve the simplicity of the clinical process for the clinicians and reduce the discomfort of patients.

OPEN ACCESS Purpose: The purpose of this study was to investigate the validity and reproducibility of a method based on cone-beam computed tomography (CBCT) technology for the visualization and measurement of gingival soft-tissue dimensions. Material and Methods: A total of 66 selected points in soft-tissue of the ex vivo head of an adult pig were investigated in this study. For the measurement of radiographic thickness (RT), wet softtissue surfaces were lightly covered with barium sulfate powder using a powder spray. CBCT was taken and DICOM files were assessed for soft-tissue thickness measurement at reference points. A periodontal probe and a rubber stop were used for the measurement of trans-gingival probing thickness (TPT). Af ter flap elevation, actual thickness of sof t-tissue (actual thickness, AT) was measured. Correlation analysis and intraclass correlation coefficients analysis (ICC) were performed for AT, TPT, and RT. Results: All variables were distributed normally. Strong significant correlations of AT with RT and TPT values were found. The two ICC values between TPT vs. AT and RT vs. AT differed significantly. Conclusion: Our results indicated that correlation of RT was stronger than that of TPT with AT. We concluded that soft tissue measurement with CBCT could be a reliable method, compared to the trans-gingival probing measurement method.","PeriodicalId":370954,"journal":{"name":"The Korean Academy of Oral and Maxillofacial Implantology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116981994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OPEN ACCESS Purpose: The objective of this study was to investigate the reproducibility of milled acrylic resin and zirconia models using three-dimensional analysis. Material and Methods: Zirconia discs and acrylic resin blocks were milled to make models. Each model was scanned with a model scanner. The zirconia models were superimposed with other zirconia model, and the acrylic resin models were superimposed with other acrylic resin model threedimensionally. Root-mean-square (RMS) values were obtained. Distances between two superimposed models were measured. Statistical significances were tested using the Mann-Whitney U test and t-test. Results: The RMS values of the zirconia model and the acrylic resin model were not significantly different (p≥0.05). At the premolar site, distances between the zirconia models at the upper axial and at the lower axial wall were significantly smaller than for the acrylic resin models (p<0.05). At the molar site, distance between the zirconia models at the lower axial wall was significantly smaller than for the acrylic resin models (p<0.05). Conclusion: Although there is a difference in reproducibility between the milled acrylic resin model and the zirconia model in the localized region, no significant difference was found in the whole model.","PeriodicalId":370954,"journal":{"name":"The Korean Academy of Oral and Maxillofacial Implantology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125491212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OPEN ACCESS Alongside the development of digital devices and materials, the concept of digital dentistry has been advancing throughout the field of prosthetic dentistry. Patients with missing teeth often visit dental clinics in a functionally and esthetically disrupted state. Provisional restorations play an important role in setting the patient-specific information, such as the position and alignment of teeth for esthetics, pronunciation, lip support, vertical dimension and occlusal plane. In conventional methods, there are many difficulties in reflecting provisional prosthesis to final restorations. However, with the double scanning method, which is a process of superimposing and replicating scanned models of provisional prosthesis on a definitive model, it is easier to reflect provisional restorations to final ones. It also has the advantages of simplifying the manufacturing process, and making it possible to reproduce the same prosthesis when it has been fractured or lost. In this case report, two patients went through a provisional restoration phase to evaluate function and esthetics. The final monolithic zirconia implant restorations were fabricated using the double scanning method. These cases are presented to show that with CAD/CAM technology and double scanning method, it is possible to fabricate an esthetic and functional final restoration that reflects the provisional restoration.","PeriodicalId":370954,"journal":{"name":"The Korean Academy of Oral and Maxillofacial Implantology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127499816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OPEN ACCESS Introduction: Patients with oroantral fistula usually have severe alveolar bone defects. Alveolar bone augmentation procedure may be needed when placing implant in atrophic bone. Currently, various alveolar bone augmentation techniques are recognized as promising treatments. The purpose of this study is to evaluate the results of simultaneously performed sinus augmentation, guided bone regeneration (GBR) and block bone graft procedures in patient who have the severe alveolar bone loss with oroantral fistula. Case: A 58-year-old male patient was referred for implant removal at #15, 16 intruded in the right maxillary sinus. At first, implant fixture was removed and, #14 was extracted. After 7 months, combination technique including sinus augmentation & block bone graft & GBR was carried out. Sinus augmentation was performed by the lateral approach. The bone block harvested from the mandibular ramus was performed. The bone block is placed on the alveolar bone and fixed with a screw to the alveolar bone with GBR. At 7 months af ter bone augmentation, Implants were placement at the #14, 16, 17 edentulous site. After implantation 6 months, implant second operation was done. And the prosthetic procedure was completed. Conclusion: Healing occurs without complications and at 9 months follow-up check, normal clinical and radiological findings were observed.","PeriodicalId":370954,"journal":{"name":"The Korean Academy of Oral and Maxillofacial Implantology","volume":"108 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113945632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OPEN ACCESS Restoration with fixed prostheses using implants is a generalized treatment method in partially or fully edentulous patients. In the past, where only the function of the implant prostheses was emphasized, successful osseointegration was just enough to be considered clinically satisfactory. Recently, however, as the patient’s demands have increased, the recovery of function and esthetics similar to the lost natural teeth has become an important issue for implant prostheses restoration. There may be controversy as to whether occlusion of natural teeth can be applied to implants with different morphological, histological, and dynamical characteristics f rom those of natural teeth. Therefore, this article will investigate the possibility, prerequisites, limitations and solutions of implant occlusion formation similar to natural teeth.","PeriodicalId":370954,"journal":{"name":"The Korean Academy of Oral and Maxillofacial Implantology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124958496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
