Kim, Yong-Gun ; Byun, Jin-Seok ; An, Seo-Young ;
Journal of Dental Rehabilitation and Applied Science, volume 30, issue 1, 2014, Pages 1~8
DOI : 10.14368/jdras.2014.30.1.1
Purpose: The purpose of this study was to investigate the effect of head position changes on vertical and horizontal magnification in dental panoramic radiographs. Materials and Methods: Five 4 mm metal balls were placed above alveolar crest of dry skull considering extraction socket and dental arch. Panoramic radiographs were taken by OP-100D (Instrumentarium Imaging Co., Tuusula, Finland) at proper and rotated head position along the sagittal and transverse axis at 3 -
upwardly, downwardly, to the left and to the right rotation. Images were stored in DICOM files and were measured by ruler equipped within INFINITT PACS software. Results: The mean horizontal magnification was
and mean vertical magnification was
at standard head position. There was statistical significance of horizontal magnification between the anterior (
) and the posterior area (
) (P < 0.05). Vertical magnification resulted in less variation (
) than horizontal magnification (
) according to the rotation. There was statistical significant difference on horizontal magnification (P < 0.05). Conclusion: In rotated head position, the horizontal magnification should be considered because these can cause distortion on panoramic radiographs.

Purpose: Implant engine system is composed of the handpiece, micromotor, control box and foot switch. The aim of this study was to evaluate the satisfaction of the implant engine systems in terms of convenience-design and to examine the relation with the experience of implant surgery. Materials and Methods: Three implant systems were evaluated: SurgicXT/X-SG20L, INTRAsurg300/CL3-09, XIP10/CRB26LX. For this comparative study, 30 dentists were included and the satisfaction was measured using a structured questionnaire. One-way analysis of the variance (ANOVA) and multiple regression analysis were used within and between the groups. Results: Total satisfaction differed from each other (P < 0.05). The convenience score was more associated with the total satisfaction than design score. Moreover, the implant surgery experience affected several assessments. Conclusion: Collectively, in a cross-sectional study model, the design of implant system significantly affects its total satisfaction and the surgery experience can be influential factor in the evaluation of implant engine system.

Lee, Wan-Sun ; Park, Jong-Kyoung ; Kim, Wook-Tae ;
Journal of Dental Rehabilitation and Applied Science, volume 30, issue 1, 2014, Pages 16~22
DOI : 10.14368/jdras.2014.30.1.16
Purpose: The purpose of this study was to assess the marginal and mesial fitness of zirconia single copings and 3-unit fixed partial dentures (FPDs) manufactured with an identical model. Materials and Methods: An epoxy model in which the maxillary right 2nd premolar is lost and maxillary 1st premolar and 2nd molar are formed as abutments was manufactured and scanned by using a laser scanner. A ten units of zirconia single copings were manufactured for maxillary 1st premolar and 2nd molar, respectively and the same number of 3-unit FPDs were manufactured. For the measurements of fitness, the manufactured silicone replicas were divided into four parts and the fitness were measured by digital microscope at measurement points (P1, P2, P3, P4 and P5) of each plane. The measured gaps were classified into three categories: marginal gap (MG, P1), axial gap (AG, average of P2 and P3), occlusal gap (OG, average of P4 and P5). Results: The ranges of MG, AG and OG for single copings were 18.47 - 40.54
, 39.73 - 73.61
and 116.90 - 134.69
, respectively. The ranges of MG, AG and OG for 3-unit FPDs were 45.95 - 87.44
, 23.78 - 57.00
and 99.89 - 131.06
, respectively. Conclusion: The result of the study shows that the MGs for 3-unit FPDs were higher than those of single copings, though they are within the range of clinical acceptance, indicating that the use of more homogeneous zirconia block and modification of sintering processes are needed to ensure the prevention of increase of gap in 3-unit FPDs.

Osteochondroma is the most common benign bone tumor. The majority of osteochondromas (85%) present as solitary, nonhereditary lesions. In general, osteochondroma has no symptoms,however, facial asymmetry, malocclusion, crossbite and mouth opening can be occurred in case of temporomandibular joint involved. Radiologic analyses are indispensable element to diagnose osteochondroma and pathogenetic analysis showed that hereditary multiple osteochondromas are caused by mutations in either of two genes: exostosis(multiple)-1 (EXT1), which is located on chromosome 8q24.11 - q24.13 or exostosis(multiple)-2 (EXT2), which is located on chromosome 11p11 - 12. Recently, reduced mRNA of EXT1 was described in nonhereditary osteochondromas. The treatment of choice for osteochondroma is surgical unless the skeleton is still immature. Surgery associated with orthodontic treatment can be a valid approach to minimize facial asymmetry and malocclusion in case of temporomandibular with osteochondroma.

Bruxism is a much-discussed clinical issue in dentistry. Although bruxism is not a life-threatening disorder, it can influence the quality of human life, especially through dental problems, such as, frequent fractures of dental restorations and pain in the orofacial region. This research has a goal to investigate the diagnostic methods of bruxism, to provide an appropriate information about various treatment in clinical situation, and to evaluate the effect and the usefulness of those methods. There is no certain remedy for bruxism that is a technically efficient and definitely reliable diagnosis and treatment. So, the primary purpose is to prevent the oral and maxilofacial tissue injuries from bruxism and to relieve the pain and symptom. Therefore, Combining various reversible treatments together, such as behavior modification, Oral appliances therapy and physiotherapy, is recommended. For a bruxism treatment in dental field, more researches about the factors influencing on diagnosis and cure are necessary.

Diagnosis and treatment planning is initial step to fabricate removable partial denture, and one of most important factor influencing the prognosis. Partial edentulous patients have various condition of remaining teeth and oral mucosa. Therefore, for the proper diagnosis and treatment planning for each patient, getting many informations from patients during initial examination and fabricating accurate diagnostic cast are required. Especially, because the use of various diagnostic tools and surveying of diagnostic cast will be a guide for the abutment teeth selection, oral preparation and design of partial denture, dentist should understand and be able to apply this procedure during diagnosis.

Growing of number of elderly populations, which may be caused by improved quality of life and decreased the percentage of mortality. Although there is a declining rate of the edentulous patients, more patients are advancing into older age groups, and the substantial number of edentulous patients are increasing. For these edentulous patients, complete denture cannot substitute natural teeth, but it is a staple prosthetic treatment. Generally, the success of dentures has been evaluated on the basis of whether or not patients comfortable and were able to masticate with their dentures. Acceptance of complete denture is complex for patients and related to psychological factors of patients, physical state, and the technical quality of dentures. In addition to that, many factors influence to satisfaction of patients to the complete dentures. In this review article, evaluate various factors related on satisfaction of denture wearers and methods of evaluate satisfaction.

Full-mouth reconstruction of a patient using dental implants is a challenge if there is vertical and horizontal bone resorption. Therefore, it is should be cautious in making the fixed prostheses that restore the function and the esthetics of the gingiva and teeth. In full mouth rehabilitation, CAD/CAM system makes it possible to fabricate restorations with high precision, regardless of span of the restoration. Recently, Palladium-silver (Pd-Ag) alloy which is highly biocompatible and millingable has been developed to compensate for the shortcomings of the titanium or zirconia. This clinical report presents the reconstruction of a maxillary arch with a cement retained implant supported fixed prosthesis using a Pd-Ag alloy generated by CAD/CAM system on eleven osseointegrated implants. The occluding surfaces were made of Pd-Ag alloy, to decrease the risk of chipping or fracture. The prostheses were esthetically pleasing, and no clinical complications have been reported after two years.
Reconstruction of upper anterior by implant using customized zirconia abutment and all ceramics: a clinical report
Kim, Ja-Yeong ; Seo, Jae-Min ;
Journal of Dental Rehabilitation and Applied Science, volume 30, issue 1, 2014, Pages 81~92
DOI : 10.14368/jdras.2014.30.1.81
It is so hard to obtain optimal anterior esthetics in the implant prosthesis. This is not only because of hard and soft tissue problem such as alveolar bone resorption and interdental papilla loss but also because of prosthetic limitation related to marginal exposure of metal abutment and metal ceramics and low transillumination. In this case, guided soft tissue healing is obtained using a long term provisional restoration with soft and hard tissue augmentation or immediate implantation. Then, this healed tissue is transferred to final master model using a customized impression coping and the implant is restored with a customized zirconia abutment and a all ceramics. This case presents satisfying result esthetically and functionally.
