The removable platform switching technology (multiunit, Оn1) was tested intraoperatively using the passive placement technique as exemplified by a conical connection implant system, which makes it possible to visually control the placement of these platforms with respect to the alveolar bone in the correct orthopedic position. The technology is characterized by a rapid epithelialization of tissues around the base platform until the final integration of the implant, minimal trauma in the emergence profile zone, and an improved minimally invasive orthopedic protocol for working on a removable platform switching base.

The use of mini-implants have made a major contribution to orthodontic treatment. Demand has aroused scientific curiosity about implant placement procedures and techniques. However, the reasons for instability have not yet been made totally clear. The aim of this article is to establish a relationship between implant placement technique and mini-implant success rates by means of examining the following hypotheses: 1) Sites of poor alveolar bone and little space between roots lead to inadequate implant placement; 2) Different sites require mini-implants of different sizes! Implant size should respect alveolar bone diameter; 3) Properly determining mini-implant placement site provides ease for implant placement and contributes to stability; 4) The more precise the lancing procedures, the better the implant placement technique; 5) Self-drilling does not mean higher pressures; 6) Knowing where implant placement should end decreases the risk of complications and mini-implant loss.

As immediate loading protocols are becoming more frequent, the primary stability of implants has become an essential criterion for the osseointegration of dental implants. Based on this, the objective of this study was to understand the influence of different undersized surgical preparation sites on the insertion torque (IT) and implant stability quotient (ISQ). Four different site-preparation protocols were performed on fresh humid type III bovine bone: one control, the standard protocol recommended by the manufacturer (P1), and three variations of undersized techniques (P2, P3 and P4). The implant used was VEGA by Klockner Implant System. The sample size was n = 40 for each of the four groups. A torquemeter was used to measure the IT, and the ISQ was measured with a Penguin RFA. Both variables showed a tendency to increase as the preparation technique was reduced, although not all the values were statistically significant (p < 0.05) when comparing with the standard preparation. The preparations without a cortical drill, P2 and P4, showed better results than those with a cortical drill. Given the limitations of this study, it can be concluded that reducing the implant preparation can increase both the IT and ISQ. Removing the cortical drill is an effective method for increasing implant stability, although it should be used carefully.

Esophageal atresia is fundamentally important in pediatric surgery, as its treatment results create an accurate portrait of the standards of surgical care, which is provided by any medical institution. Cameron Haight performed the first successful reconstruction of the esophagus malformation relatively recently just over 70 years ago. Advances in neonatal surgery, technology and advances in neonatal intensive care have dramatically improved treatment outcomes for this disease. Current mortality from this developmental abnormality has become minimal, despite its frequent association with other malformations. A revolutionary approach to the treatment of esophageal atresia was developed by Steven Rothenberg in 1999, the pioneer and legend of pediatric minimally invasive surgery. In 1999, he revolutionized esophageal anastomosis by thoracoscopy. The innovative concept of the minimally invasive approach ensured minimal trauma to patients, thereby providing the possibility of rapid postoperative recovery of patients and reducing the length of their surgical hospital stay. This literature review raises the main controversy in the surgical treatment of esophageal atresia in the 21st century. Emphasis is placed on the study of the role of minimally invasive surgery and the treatment of concomitant abnormalities associated with gastroesophageal reflux and tracheomalacia. As part of the study, a description of all the latest technologies, advances in technical and scientific terms, solutions, exceptional experience, and competence in developing and implementing minimally invasive operations in young children. These developments changed the direction of pediatric surgery and improved the quality of surgical care for children with congenital malformation of the esophagus and how they were performed.

Celiac trunk compression syndrome is a symptom complex arising from compression of the celiac trunk by the median arcuate ligament, crura of diaphragm or ganglion tissue of the celiac plexus. The main clinical manifestations of this pathological condition are abdominal pain syndrome, indigestion and weight loss. The disease is detected in 0.4–1 % of people in the population, more often in young people. The pathophysiological mechanisms of the development of celiac trunk compression syndrome remain not fully understood, but the key reason for its development is ischemia of the digestive system. The main instrumental methods for diagnosing compression of the celiac trunk are ultrasound duplex scanning of the abdominal aorta and visceral arteries and spiral computed angiography. The only effective treatment for celiac trunk compression syndrome is surgery. Currently, both classical techniques and various minimally invasive technologies are used to decompress the celiac trunk. The advantages of open access include good visual and manual control of anatomical structures, the possibility of eliminating complications, changing the tactics of surgical intervention, if necessary, performing vascular reconstruction. The advantage of minimally invasive surgical technologies is minimal trauma to the abdominal wall tissues, minor postoperative pain syndrome, early rehabilitation, a low risk of developing cusp, wound infection and hernial defects. Regardless of the methodology, surgical treatment can achieve a positive effect in 75–90 % of patients with celiac trunk compression syndrome. These are the modern concepts of epidemiology, pathogenesis, clinical manifestations, diagnosis and methods of treatment of this pathological condition.

The bone available for implant placement may be limited by the presence of the maxillary sinus togetherwith loss of alveolar bone height and it may be increased by augmentation. Minimally invasive sinusaugmentation is an effective solution for this problem. This review explains indirect sinus augmentationprocedures which are less invasive and highly successful if done using prescribed technique.
