To improve esthetics and gain beautiful smile, the maxillary anterior dentition is crucial. Through alteration of height, arrangement or color of the maxillary incisor, we can rehabilitate the esthetic smile. The perception of dental esthetics is highly subjective. Personal perceptions or judgement of dental esthetics is highly related with each individual’s experience and social and cultural environment. However, there have been many efforts to establish the criteria for generally accepted esthetic norm, in order to increase the predictability of restorative treatment. For maxillary anterior restoration, not only a single tooth, but also the compositions around tooth such as facial form, lips and gum and their relationships have to be considered to create harmonious smile. It can be determined as esthetic restorations when in consonance with facial form and structures that frame the restorations. In this review article, several guidelines that are generally accepted and useful to assess the esthetics and communicate with patients and technicians will be discussed.
There is a difficulty for many practioner in anterior direct restroation with composit resin. Because its result is various according to patient, a practioner have a fear about that unpromisable result. Moreover in esthetic region, there is difference in satisfaction by patient character. That is one of difficulty in this practice. But if we make a manual for parctice it will be easier. So I will summarize the process and things to note in direct anterior composite resin restoration.
estorations. “The provisional restoration followed by an adequate tooth reduction” and “the accurately fitting prostheses with corresponding to final impression” can be the examples of them. Nevertheless, the one which all-ceramic restorations are distinguished from conventional restorations is the additional procedure of so called “bonding”. In addition to the application of resin cement between “inner surface of restoration and outer surface of abutment”, bonding technology can be also applied to the treatment process of “Post and Core” in particular if the abutments are non-vital teeth. Core build-up for all-ceramic crown is conducted with fiber post and tooth colored composite by considering the properties of the restorations transmitting light. I would like to share my clinical experience about "silica based ceramic and non silica based ceramic restoration.
Objectives: This study evaluated the outcomes of continuing professional education in implant dentistry using Kirkpatrick's four-level evaluation model. Material and methods: The study was carried out through a questionnaire distributed to dentists who attended a continuing professional education in implant dentistry, 2008~2012. They were asked to fill out questionnaires at least 6 months after its completion. Results: Mean ages of total 23 dentist was 44.8°æ8.2. Mean period after completion of education was 2.7°æ1.2. Knowledge (level 2) (r=0.71, p<0.01) and behavior (level 3) (r=0.68, p<0.01) was positively correlated with topic and methods of education in reaction (level 1). Behavior was positively correlated with knowledge (r=0.79, p<0.01). Result (level 4) was positively correlated with knowledge (r=0.64, p<0.01) and behavior (r=0.86, p<0.01). Conclusion: Reaction affects on knowledge, behavior and result in order.
SFI-bar is prefabricated bar system and can be assembled at chairside without soldering or welding, thus reducing bone loss, costs and time. A 53-year-old male patient, who had severely absorbed mandible, hoped to wear a stable mandiblular denture. Four implants were placed in the extraction site of canine and 1st molar. Early loaded temporary denture with solitary type attachment was delivered 3 weeks after surgery. 3 month later, SFI-bar was connected and adjusted at chairside. Then, implant overdenture using SFI-bar was delivered. This case report showed that a satisfactory clinical result was achieved by 4-implantsupported overdenture using the SFI-Bar system in a mandibular edentulous patient.
An oro-antral fistula(OAF) is one of the most common complications after procedures at the maxillary posterior area. The purpose of this study was to introduce the closure of OAF with repair of the Schneiderian membrane. This case report includes three patients with OAF arising after dental surgery on molar region of maxilla. Under general anesthesia, fistulectomy was achieved in all three patients and the full thickness flap around OAF was raised. After removal of inflammatory tissue, the Schneiderian membrane was repaired with suture or application of fibrin sealant. Additional closures were then performed with a buccal fat pad flap and a buccal mucoperiosteal flap. All OAF in three patients enrolled in this study were closed successively without recurrence of fistula. Treatment of oroantral fistula using repair of the Schneiderian membrane is a good alternative option for patients with OAF accompanied by chronic maxillary sinusitis.
This study was to evaluate the effects of oral health education conducted on air force personnel according to the use of disclosing solution. They were divided into 3 groups: Group A: oral health education was not conducted, Group B: oral health education was conducted without using disclosing solution, and Group C: oral health education was conducted using disclosing solution. The subjects who had not participated in the education at least once were excluded, and the remaining 83 subjects received oral health education four times and one time each week. The probing depth, plaque index, gingival index, and bleeding on probing were measured one week before the implementation of the first oral health education and one week after the implementation of the fourth oral health education. The results of verifying the homogeneity of the clinical indices before the oral health education showed statistically significant differences in bleeding on probing among the three groups. The results of comparing the clinical indices among the three groups after the oral health education exhibited statistically significant differences in the plaque and gingival indices among the three groups. Groups B and C showed lower values than Group A. The comparison of the clinical indices before and after the oral health education showed statistically significant improvements in all clinical indices after the education in Group C. The results suggested that the oral health education using disclosing solution could maximize that visual effects and encourage self-motivation, consequently improve the oral hygiene of the patients.
Ebola virus disease is a lethal viral hemorrhagic fever that has been boiling in sub-Saharan Africa since 1970s. Last year, The Ebola virus epidemic that has spread not only mainly in West Africa, but also in locals such as USA, Europe and the Antipodes via infected travelers, was brought up. Human-to-human transmission of Ebola virus disease is known only through direct contact with the blood, secretions, tissues or other bodily fluids, including saliva. Although there has not been reported infection cases in the dental healthcare settings, the fact that the infection of the Ebola virus may be made from human secretions such as saliva suggests that there is a high risk of infection for the Ebola virus of dental healthcare workers. Therefore, it is important dental healthcare workers to identify infection-suspected patients through the oral findings for infection prevention. This article will review the oral signs and symptoms of Ebola virus disease and discuss the pathogenesis, treatment and prevention. Furthermore, Infection control guidelines for oral healthcare workers are also proposed.
