In the filed of Dentistry, minimally invasive treatment modalities are new trend for conservation of natural teeth. Of them, laminate veneer and resin bonded fixed partial denture belong to restoration procedures. In this review, survival rates of each modalities and cause of unserviceability are analyzed, and criteria for success are presented. To get successful results of minimally invasive restoration, plenty of enamel layer, thin and strong materials, and high bonding strength are essential under cyclically loaded wet oral condition. Newly tried design of minimally invasive technique nowadays have to be evaluated only on the basis of requirement for long-term success.

Crown fractures are relatively common trauma to anterior teeth, and should be restored immediately in most cases. For those who suffer from unfortunate traumatic episode, the best treatment option should be minimally invasive approach. In the presence of fractured tooth fragment, reattachment procedure creates positive emotional response in the patient and simplifies the procedure and maintenance of the patient's original tooth anatomy and occlusion. Without fractured tooth fragment, next conservative option could be direct composite restoration which is based on minimal invasion concept. This article proposes simple and very conservative techniques that anyone can do in daily practice.

Acute Achilles tendon rupture is a frequent injury during sports and recreational activities. Treatments for Achilles tendon rupture have been controversial in recent decades. Traditionally the surgical treatment had benefit over nonsurgical treatment in terms of low rerupture rate and early functional restoration. Recently, nonsurgical treatment was found to show no statistically significant inferiority in re-rupture rate, functional outcome, and calf strength. Whereas, surgical treatment had some complications including adhesion, nerve injury, and infection. Nonsurgical treatment has been increasing due to functional rehabilitation with early weight bearing and restricted early motion. It focuses more attention on the course of caring for patients with deep discussion. There are open repair and minimally invasive repair in terms of surgical treatment. There are various techniques for minimally invasive repair of Achilles tendon, which has some advantages over the open repair. However, the optimal technique for minimally invasive repair has not been established. The number of suture strands is important regardless of suture technique.

Purpose: The purpose of this study is to analyze the clinical and radiological results of minimally invasive percutaneous screw fixation in intra-articular calcaneal fractures and its complications. Materials and Methods: This study is based on 30 intra-articular calcaneal fractures that treated by index operation from June 2005 to November 2006 with at least 6 months follow-up. We assessed the clinical and radiological outcomes and complications. Results: According to Sanders classification, there were 8 in type IIA, 7 in type IIB, 3 in type IIIAB, 6 in type IIIBC, 6 in type IV. And according to Essex-Lopresti classification, there were 9 in the tongue type, 21 in the joint depression type. Average follow-up period was 14.6 months (range: 6-23 months). Average interval between from injury to operation was 2.3 days. Average AOFAS score was 87.7 (range: 52-92). Satisfactory results were obtained in 22 cases (73.3%) by AOFAS score and in 20 cases (66.7%) by VAS score (mean: 3.4). Radiological results improved from 8.7 to 20.3 degrees in the Bohler angle and from 40.2 mm to 52.1 mm in calcaneal height. Postoperative complications were 2 skin and soft tissue problems and 1 sural neuropathy. Conclusion: Minimally invasive percutaneous screw fixation may be useful alternative surgical method in the management of Sanders type II and III calcaneal fractures, which is possible to achieves the anatomical restoration and minimizes postoperative complication in patients with high risks of soft tissue compromise and allows relatively early operation.

Objective : To report long-term clinical and radiological outcomes of minimally invasive posterior cervical foraminotomy (MI-PCF) performed in patients with unilateral single-level cervical radiculopathy. Methods : Of forty-six patients who underwent MI-PCF for unilateral single-level radiculopathy between 2005 and 2013, 33 patients were included in the study, with a mean follow-up of 32.7 months. Patients were regularly followed for clinical and radiological assessment. Clinical outcome was measured by visual analogue scale (VAS) for the neck/shoulder and arm, and the neck disability index (NDI). Radiological outcome was measured by focal/global angulation and disc height index (DHI). Outcomes after MI-PCF were evaluated as changes of clinical and radiological parameters from the baseline. Mixed effect model with random patients' effect was used to test for differences in the clinical and radiological parameters repeat measures. Results : There were no complications and all patients had an uneventful recovery during the early postoperative period. VAS scores for neck/shoulder and arm improved significantly in the early postoperative period (3 months) and were maintained with time (p<0.001). NDI improved significantly post-operatively and tended to decrease gradually during the follow-up period (p<0.001). There were no statistically significant changes in focal and global angulation at follow-up. Percent DHIs of the upper adjacent or operated disc were maintained without significant changes with time. During the follow-up, same site recurrence was not noted and adjacent segment disease requiring additional surgery occurred in two patients (6%) on the contra-lateral side. Conclusion : MI-PCF provides long-term pain relief and functional restoration, accompanied by good long-term radiological outcome.

Minimally invasive surgery for gastric cancer has increased in popularity during the last two decades mainly in the Asia for patients with early-stage cancer. Nevertheless, the development of laparoscopic surgery for gastric cancers in the Western world has been slow because of the advanced stage at diagnosis for which LG is not yet considered an acceptable alternative to standard open surgery. RAG has been reported as a safe alternative to conventional surgery for treating of early gastric carcinoma. We assess the current status of robotic surgery in the treatment of gastric cancer focusing on the technical details, postoperative outcome, oncological considerations and future perspectives. In gastrectomy the biggest advantage of the robotic approach is the ease and reproducibility of lymphadenectomy. Reports also show that even the intra corporeal digestive restoration is facilitated by use of the robotic approach, particularly following TG. Additionally, the accuracy of robotic dissection is confirmed by decreased blood loss in comparison to conventional laparoscopy. The learning curve and technical reproducibility also appear to be shorter with robotic surgery and, consequently, robotics can help to standardize and diffuse minimally invasive surgery in the treatment of gastric cancer. While published reports have shown no significant differences in surgical morbidity, mortality, or oncological adequacy between robot-assisted and conventional gastrectomy. There are some advantages in terms of postoperative recovery of patients after robotic surgery. More studies are needed to assess the true indications and oncological effectiveness of robotic use in the treatment of gastric carcinoma.

비록 기성 금속관 수복이 유구치 수복 시 가장 효과적이고 내구성 있는 방법으로 인지되어 왔지만, 그것은 치과의사들에게 있어서 복합한 시술이 가지는 침습적 특징과 행동 조절 문제와 같은 명확한 단점을 가지고 있다. 전통적인 기성 금속관 수복 방법에 대한 대안으로 1988년 Hall technique이 소개되었는데, 이것은 국소마취, 우식제거, 치아삭제 없이 지대치위에 시멘트가 채워진 금속관을 합착하는 것으로 특징지어진다. 몇몇 보고들에 따르면, 그 비외상적인 특성은 전통적인 수복보다 어린이에게, 특히 저연령 어린이에게 더 적은 불편감과 스트레스를 준다. 또한 Hall technique은 치과의사, 어린이, 그리고 부모에게 효과적이고 받아들일 만 하다고 보고되어 왔다. 이 증례에서, 4세 5개월, 4세 10개월, 6세 4개월의 어린이 3명의 제1유구치를 Hall technique을 이용하여 기성 금속관 수복을 시행하였다. 3~6개월간의 정기검진 후 현재까지 치수, 치아, 또는 연조직에 명확한 합병증 없이 임상적으로 성공적인 결과를 보여주고 있다. 그러나, Hall technique이 모든 어린이, 우식 유구치, 또는 치과의사에게 적합하지는 않다는 것을 유념하고, 적응증의 엄격한 선택과 지속적인 정기 검진이 요구된다. 결론적으로, Hall technique은 효능에 대한 잠재적인 의구심과 일부 명확한 제한점에도 불구하고 특히 저연령 어린이나 장애 어린이의 우식 유구치 수복 방법에서 효과적이고 현실적인 최소침습적 대안이 될 수 있다.
