Regenerative therapy in an interproximal intrabony defect is a challenge due to unaesthetic appearance after surgery. In this article, we introduce a case series of additional use of autogenous periosteal barrier membrane combined with bovine bone mineral and enamel matrix derivative (EMD) in interproximal periodontal intrabony defects to overcome an aforementioned shortcoming. During the periodontal regenerative surgery, autogenous periosteal membrane was additionally adopted besides xenograft material and EMD. Clinical and radiographic examinations were performed before surgery and 6 months after surgical treatment. All clinical parameters were improved and the intrabony defects were resolved on the radiography 6 months after surgery. Moreover, soft tissue esthetics such as the contour of interdental papilla was better than that of conventional regenerative therapy. Periodontal regenerative therapy using several graft materials and bioactive materials was effective in the treatment of periodontal intrabony defect. Moreover, using of autogenous periosteal barrier membrane combined with xenograft and EMD has additional effect for the treatment of an interproximal intrabony defect in terms of augmentation of interdental soft tissue volume.

Closed mouth impression technique by using bite tray is preferred for single tooth impression taking. However, for implant impression taking, open mouth impression technique by using single arch tray is generally used whether it is for single implant or multiple implant. Closed mouth impression technique by using bite tray can save time and materials. It also decreases the chance of error occurrence when a model is mounted on an articulator. In this case report, we tried to show a satisfying result of fabricating single implant fixed prosthodontics after bite tray impression taking by using two different copings for closed mouth impression.

Intellectual disability is an imperfect disorder in which mental development is permanently retarded and development of intellectual ability is inadequate. Having intellectual disabilities makes it difficult to handle their own work and adapt to social life. For this reason, it is difficult to hygienically manage the patient's oral condition, multiple caries are easily observed, and the periodontal disease incidence rate is high. The patient in this case is a 33-year-old female with a mental retardation first grade who had a problem with meals. In first visit, Patients had decreased occlusal vertical dimension and posterior bite collapse due to periodontitis and multiple caries. This case reports a satisfactory functional and esthetic results by reconstructing occlusion using partial removable dental prosthesis.

Many factors should be considered for successful denture treatment at edentulous patients: support, retention, stability, occlusion, esthetics, etc. The patient who has severely absorbed residual ridges, however, treatments are challenging to satisfy those factors. The dentures that use anatomic artificial teeth show good mastication efficiency and esthetics but, can easily lose stability at absorbed ridges. On the contrary, the dentures that use non-anatomic artificial teeth perform better stability but, lower masticatory efficiency and esthetics at absorbed ridges. The lingualized occlusion, using both anatomic and non-anatomic teeth, introduced for compromise those of the pros and cons. At lingualized occlusion, buccal cusps of the teeth do not contact on centric relation. Therefore, direction of the occlusal force towards lingually, then stability of dentures increases. This case report shows the results of the treatment flat residual ridges using complete dentures with ligualized occlusion to increase dentures stability and satisfactory of the patient.

PURPOSE: This study aims to analyze the stress distribution of mandibular molar restoration supported by the implants with external hex and internal taper abutment connection design. MATERIALS AND METHODS: Models of external connection (EXHEX) and internal connection (INCON) implants, corresponding abutment/crowns, and screws were developed. Supporting edentulous mandibular bony structures were designed. All the components were assembled and a finite element analysis was performed to predict the magnitude and pattern of stresses generated by occlusal loading. A total of 120 N static force was applied both by axial (L1) and oblique (L2) direction. RESULTS: Peak von Mises stresses produced in the implants by L2 load produced 6 – 15 times greater than those by L1 load. The INCON model showed 2.2 times greater total amount of crown cusp deflection than the EXHEX model. Fastening screw in EXHEX model and upside margin of implant fixture in INCON model generated the peak von Mises stresses by oblique occlusal force. EXHEX model and INCON model showed the similar opening gap between abutment and fixture, but intimate sealing inside the contact interface was maintained in INCON model. CONCLUSION: Oblique force produced grater magnitudes of deflection and stress than those by axial force. The maximum stress area at the implant was different between the INCON and EXHEX models.

PURPOSE: We compared the effects of newly developed diode laser (Bison 808 nm Diode laser) on the treatment of peri-implantitis with conventional products (Picasso 810 nm Diode laser) by comparing the surface temperature of titanium disc and bacterial sterilization according to laser power. MATERIALS AND METHODS: The titanium disc was irradiated for 60 seconds and 1 – 2.5 W using diode laser 808 nm and 810 nm. The surface temperature of the titanium disc was measured using a temperature measurement module and a temperature measurement program. In addition, in order to investigate the sterilizing effect according to the laser power, 808 nm laser was irradiated after application of bacteria to sandblasted large-grit acid-etched (SLA) and resorbable blast media (RBM) coated titanium discs. The irradiated disks were examined with scanning electron microscopy. RESULTS: Both 808 nm and 810 nm lasers increased disk surface temperature as the power increased. When the 810 nm was irradiated under all conditions, the initial temperature rise rate, the descending rate, and the temperature change before and after was higher than that of 808 nm. Disk surface changes were not observed on both lasers at all conditions. Bacteria were irradiated with 808 nm, and the bactericidal effect was increased as the power increased. CONCLUSION: When applying these diode lasers to the treatment of peri-implantitis, 808 nm which have a bactericidal effect with less temperature fluctuation in the same power conditions would be considered safer. However, in order to apply a laser treatment in the dental clinical field, various safety and reliability should be secured.

Patient management is considered an important factor in dental field. The aim of this review is to analyze the efficacy of hypnosis to treat fear, anxiety, pain, stress of dental patients, and see how it can be adopted in dentistry for improving patient satisfaction. Medline research was carried out to find the use of hypnosis in dentistry and other aspects of hypnosis in medical area. It can help patient more comfortable, relax, and accordingly reduce patient's negative feelings such as fear, anxiety, pain, stress during dental treatment. Also, it affects patient recovery after surgery by accelerating healing speed and reinforce immune system. When hypnosis is used with other anesthetic method, it can reduce the use of main medication, leading to reduce possibility of side effect. Therefore, using Hypnosis can give patients more comfortable dental experience, both mentally and physically, ultimately making patients more satisfied with the dental treatment.
