Tooth loss in the anterior mandibular region can be a challenging situation for dentists and dental technicians tasked to provide an esthetically pleasing prosthetic rehabilitation. For reasons of stability, a solid, torsion-resistant framework is a must in these cases. Metal frameworks have the drawback that thinner ceramic veneer layers may yield esthetically less satisfactory results. Monolithic zirconia frameworks usually do not meet the esthetic requirements of the dentist and patient in these situations. However, care must be taken to ensure sufficient strength even for delicate bridges to achieve satisfactory long-term results. The case described here was treated with the new Celtra Press pressable ceramic system (Dentsply Sirona Prosthetics, Hanau, Germany). This outstanding system combines high strength with brilliant esthetics and is ideally suited for demanding cases such as this one.

Direct composite restorations for the posterior region have become a standard part of modern conservative/restorative dentistry. This type of restoration is very popular with patients and dentists alike, and its performance in the masticatory loadbearing posterior teeth has now been demonstrated in numerous clinical studies. In addition to composites based on conventional methacrylate chemistry, ormocer composites can also be used for this range of indications.

Multidisciplinary collaboration plays a significant part in achieving predictable treatment results. This article raises awareness of the importance of accurate case analysis and preoperative planning. The case report describes the reconstruction of two lost central incisors in the anterior maxilla. After tooth 11 was extracted, measures for preserving the alveolar ridge were performed. After eight weeks, an implant was placed and a screw-retained temporary bridge was fabricated. Prior to inserting the temporary bridge, tooth 21 was extracted and immediately replaced by an implant.

Dentists believe that their profession is more stressful than other health professions. They are prone to professional stress, burnout, anxiety disorders and clinical depression, owing to the nature of clinical practice and the personality traits common among those who decide to pursue careers in dentistry. The most stressful stressors were financial issues. Stress can cause many health problems such as of cardiovascular disease, musculoskeletal, brain injury, emotional illness, ulcers, colitis, hypertension, asthma lower back pain, eye strain, alcoholism, drug addiction, mental depression and suicide. Also, it influences on family relations, teamwork and patients. It is important for dentists to recognize the symptoms and the effects of stress on physical, psychological and professional well being. Managing of stress can not cure it totally, but it can minimize it gradually. Stress management depends on understanding its causes and try to find the ways to avoid them. To enjoy satisfying professional and personal lives, dentists must be aware of the importance of maintaining good physical and mental health. Managing of stress depends on adopting the preventive measures from the early stages of stress. It includes the changing of work environment, building good relations with patients and teamwork, family members, and friends. Also practicing the sport, having rest and relaxing times, creating social relations with workers and continuing education.

Digital dentine core crowns enable fabrication of aesthetically attractive restorations with reduced manual effort. The procedure provides a high degree of predictability of the outcomes and is suitable for restoration of complex cases. This article shows the application of this technique by way of a patient case within the parameters of a multiphase procedure. The first part presents the method and explains the patient case up to the long-term temporary restoration.

The term reduced-diameter implants refers to all implants with a diameter of 3.5 mm or less. However, this blanket classification doesn't do justice to the wide scope of applications and indications these reduceddiameter implants are capable of. Therefore, classification in the following categories has proven useful: Group I = one-piece implant with a diameter less than 3.0 mm (mini-implants). Group II = two-piece implants with a diameter of between 2.9 mm and 3.25 mm. Group III = two-piece implants with a diameter of between 3.3 mm to 3.5 mm. These three groups are currently the focus of scientific efforts and present a potential clinical alternative to complex vertical augmentations. There have been numerous studies published documenting the high success rate of implant survival and patient satisfaction. Systematic reviews confirm these advantageous findings. This makes reduced-diameter implants a promising option for expanding the range of available treatment for narrow interstitial areas in the premolar and anterior regions. The implants are also useful for avoiding complex augmentations on otherwise medically compromised patients.

Nonspecific findings in the oral mucosa of the young patient presented here, for which no local cause was identified, contributed to the interdisciplinary intervention that revealed Crohn's disease, which was hitherto undiagnosed. This case illustrates the important role played by the dentist in interdisciplinary collaboration when there are pathological findings in the oral cavity
