A 23-year-old female with aggressive periodontitis was treated using dental implants and LAVA system. The severely compromised teeth were extracted irrespective of initial conservative periodontal treatment. An implant-supported overdenture with 4 implants was fabricated for the maxilla and all-ceramic restorations for the mandible. Esthetic and functional goals were achieved with team approach involving periodontists and prosthodontists. This case report describes a treatment procedure for a generalized aggressive periodontitis patient with severe bone resorption.

Beam hardening artifact can be caused by metal material when performing PET exam. Therefore, we studied a solution decreasing artifact caused by metallic dental implant. The higher voltage, the lesser artifact in CT exam. But Higher voltage dosen't affect PET exam. The thicker silicon the lesser artifact in CT and PET exam. Both methods make less artifact in CT and PET exam. But considering safety of patient, the way of using silicon is better.

In patients with severely atrophic mandibular posterior area, implant placement is a problematic surgical procedure. Inferior alveolar nerve transpositioning technique offers better initial stability of implant and reduce the risk of permanent nerve damages. In this case report, the patient has bilateral atrophic mandibular posterior edentulous area. We placed 3 implants on each mandibular posterior area in conjunction with bilateral inferior alveolar nerve transpositioning to achieve sufficient bone height. The patient complained of paresthesia in lower lip and chin area and ptosis of lower lip after surgery. Neurosensory function was normal in 10 weeks after surgery.

Periprosthetic joint infection (PJI) is one of the most devastating complications that can occur after shoulder arthroplasty. Although staged revision arthroplasty is the standard treatment in many cases, surgical intervention with debridement, antibiotics, and implant retention (DAIR) can be an effective option for acute PJI. We report a complex case of infected reverse shoulder arthroplasty (RSA) in a 73-year-old male. The patient had been previously treated for infected nonunion of a proximal humerus fracture caused by methicillin-resistant Staphylococcus epidermidis. He presented with a sinus tract 16 days after the implantation of RSA and was diagnosed with PJI caused by Serratia marcescens. The patient was successfully treated with DAIR and was free of infection at the last follow-up visit at 4 years postoperatively.

Titanium mesh is an alloplastic material widely used for the reconstruction of moderate-to-large skull defects. Repeated wound problems or infection following these reconstructions inevitably lead to the replacement of the cranioplasty material. Among the various alloplastic materials, polycaprolactone implants are usually used for the coverage of small defects such as burr holes. Herein, we present a case of a large cranial defect successfully reconstructed with three-dimensional-printed polycaprolactone implant and a free latissimus dorsi musculocutaneous flap. Until 1-year followup, the patient showed a favorable esthetic outcome with no complications or wound relapse.

임플란트 시술은 소위 상업화된 의료에 속하고 상대적으로 시술자체가 단순 명료하며 그 시술이 성공가능성은 거의 100%에 달한다. 또한 환자에게 건강을 위한 불가피한 수단이기 보다는 선택적 수단의 의미를 지니는바 자기결정권의 보호를 위한 설명의무의 중요성이 특히 강조되기도 한다. 이러한 특성에 비추어 임플란트 시술 계약에 대하여는 도급의 성격이 강조되어 경우에 따라서는 식립 자체의 실패만으로도 의사의 과실이 존재한다고 할 수 있을 것이다. 또한 임플란트 시술은 상업화된 의료로서 단순 명료한 의료행위인바 과실여부는 직업적 평균인이 아닌 일반인의 상식을 기준으로 판단되어야 할 것이므로, 임플란트 시술 후 악결과가 발생한 환자는 예를 들어, 시술 중 과도한 통증과 출혈이 발생하였음에도 의사가 별 다른 조치를 취하지 않았다는 등을 입증하면 충분하고 그 전문가의 입장에서 의료행위가 적절치 못하였다는 점까지 밝혀야 하는 것은 아니다. 한편, 임플란트 의료과오 판결들을 살펴보건대 법원은 명시적으로 임플란트 시술계약을 도급이라고 판단하고 있지는 않더라도, 식립 자체의 성공여부로 의사의 과실을 판단하고 있어 일의 완성을 목적으로 하는 도급계약과 유사한 특성을 어느 정도 인정하는 듯 보인다. 또한 제시하고 있는 의료과실의 구체적 내용들에 비추어 의료과실의 판단도 일반인의 상식에 기초한 것으로 보인다.

Purpose: This research sought to determine the resorption rate of bone grafted to the maxillary sinus according to the grafted material's type, patient's age, systemic disease, implant size, site of implant placement, and residual ridge height. Materials and Methods: This research targeted 24 patients who had immediate Osstem$^{(R)}$ implant (US Plus$^{(R)}$) placement after bone graft. The panorama was taken before the surgery, after the surgery, and 6 months after the surgery. Vertical height change and resorption rate of the grafted bone were measured with the same X-rays and compared. The influence of the following factors on the grafted bone material's resorption rate was evaluated: grafted material type, patient's age, systemic disease, implant size, site of implant placement, and residual ridge height. Results: Patients in their 40s had $34.0{\pm}21.1%$ resorption rate, which was significantly higher compared to the other age groups (P<0.05). There was no significant relationship between systemic disease and grafted bone resorption. There was no significant relationship between implant size (diameter, length) and grafted bone resorption. There was no significant relationship between the site of implant placement and grafted bone resorption. The ramal bone-grafted site was significantly more resorbed than the ramal bone/Bio-Oss$^{(R)}$-grafted site, maxillary tuberosity bone/Bio-Oss$^{(R)}$-grafted site, and ramal bone/maxillary tuberosity bone/Bio-Oss$^{(R)}$-grafted site (P<0.05). There was no significant difference in the grafted bone resorption rate in the sinus between more than 4 mm and less than 4 mm residual ridge heights. After an average of 6 months, a second surgery was done; given an average follow-up of 1.9 years, the success rate and survival rate of the implant were 96.9% and 98.4%, respectively. Conclusion: These results indicate that the bone resorption rate of grafted bone among patients in their 40s is higher compared to patients in their 50s and over, and that only autogenous bone (ramus) shows higher resorption rate than the mixed graft of autogenous bone and xenogenous graft (Bio-oss) after maxillary sinus graft.

Objective : This study sought to investigate the clinical survival rate of two implants with different surfaces: resorbable blasting media (RBM)-treated and calcium metaphosphate (CMP)-coated implant. Study design : SSII non-submerged implants (Osstem, Seoul, Korea) were placed in a total of 48 patients with mean age of 38.8. At least 31 patients in the experimental group had a CMP-coated implant, and 1 patient in the control group received a, RBM surface implant. The evaluation period was between April 2006 and December 2007. Radiographs, periotest, clinical periodontal examination, and prosthetic adjustment and occlusion were used. Results : The survival rate of the experimental and control groups after 1 year was 97.2% and 100%, respectively. The Wald confidence interval reported for the experimental group was not inferior to the control group. Conclusion : No significant differences were found between the RBM and CMP groups. The observed data suggest that CMP-coated methods can provide favorable clinical results for the functioning and healing of dental implants.
