The field of periodontal plastic surgery is always a subject of fascination for periodontists, and the importance of pink esthetics is gaining its pace. Preservation of what is existing is more important than its replacement. The same principle also applies to soft-tissue esthetic procedures thereby the concept of minimal surgical invasion came into existence. This article presents a series of five cases with 18 recession sites which were treated with a minimally invasive Pinhole Surgical Technique which resulted in overall root coverage of 96...

Consideration of facial muscle dynamics is underappreciated among clinicians who provide injectable filler treatment. Injectable fillers are customarily used to fill static wrinkles, folds, and localized areas of volume loss, whereas neuromodulators are used to address excessive muscle movement. However, a more comprehensive understanding of the role of muscle function in facial appearance, taking into account biomechanical concepts such as the balance of activity among synergistic and antagonistic muscle groups, is critical to restoring facial appearance to that of a typical youthful individual with facial esthetic treatments...

Orthodontic alignment of un-erupted dilacerated teeth is challenging, as the bent roots resist forces applied to move them through the bone. Various treatment options are now available to treat this condition including providing prosthesis after extractions and apicectomies. However, to maintain alveolar bone in the area of the un-erupted tooth, especially if the involved tooth is in the anterior segment, the ideal treatment would be to try and bring the tooth in the arch orthodontically. Treatment requires increased time duration, compliance of the patient, and consistent force mechanics...

PURPOSE: We conducted a review of orbital fractures treated in our hospital over a period of 4 years. We reviewed several complications of such fractures, especially the relationship of postsurgical diplopia with different presurgical variables: age, gender, type of fracture, fracture area, coronal and sagittal diameter of fracture, fractured floor area, time to surgery, presence of muscle herniation, and presence of muscle entrapment. PATIENTS AND METHODS: Fractures involving the orbital floor remain a controversial issue in terms of surgical treatment and the time from trauma to surgery...

PURPOSE: The aim of this study was to evaluate the buccopalatal volumetric tissue change that occurs following flapless single-tooth immediate extraction placement in the esthetic area and to analyze the role of four different variables. MATERIALS AND METHODS: Patients in need of a single-tooth replacement in the anterior maxillary or mandibular area (premolar to premolar) were recruited for the study. Patients were treated using four different therapeutic modalities: group 1 (healing abutment), group 2 (healing abutment + bone graft), group 3 (provisional restoration), and group 4 (provisional + bone graft)...

PURPOSE: Preoperative planning of the implant position as part of a coordinated prosthetic and surgical concept is becoming increasingly important regarding function and esthetics. The aim of this study was to investigate the transmission accuracy of template fixation during surgery in edentulous arches with hand fixation in comparison to intermediary screw fixation. MATERIALS AND METHODS: Preoperatively, 10 implant positions were planned using computed tomography (CT) with the system med3D for implant placement in four mandible models of the Goettingen study model, using a prosthetic diagnostic template...

The tooth is an intricate composition of precisely patterned, mineralized matrices and soft tissues. Mineralized tissues include enamel (produced by the epithelial cells called ameloblasts), dentin and cementum (produced by mesenchymal cells called odontoblasts and cementoblasts, respectively), and soft tissues, which include the dental pulp and the periodontal ligament along with the invading nerves and blood vessels. It was perceived for a very long time that teeth primarily serve an esthetical function. In recent years, however, the role of healthy teeth, as well as the impact of oral health on general well-being, became more evident...

In the full-mouth rehabilitation of a patient with severely collapsed occlusion, a multidisciplinary approach including prosthodontics, orthodontics, endodontics, and surgery could provide better esthetic and functional results. Orthodontic treatment aiming for stable occlusion that meets the standard requirement of functional occlusion, enables the maintenance of occlusal function, and guarantees long-term stability on the basis of periodontal health was attempted. The essential element of this protocol is careful treatment planning based on the optimal sequence pursuing functional occlusion...

Due to the increased esthetic demands, custom zirconia post-and-cores have recently become popular. A post-and-core pattern with acrylic resin or wax is scanned using a laboratory scanner for the design of a definitive post-and-core restoration. This procedure requires additional time and material handling experience. If a scan post is used for an intracanal digital impression, substantial initial investments for hardware and software are required. This article introduces an alternative technique for fabricating a custom zirconia post-and-core with a conventional impression...

For young growing children before the end of skeletal maturity, the growth activity of the grafted bone after hemimandibulectomy is not well-known. After an adolescence, such a patient may have facial deformity because the anterior growth point of the mandible is in the condylar neck. A 13-year-old boy was performed hemimandibulectomy with immediate mandibular reconstruction by fibula free flap (FFF) because of a huge ameloblastic fibroma. The authors evaluated the length of FFF on the images of computed tomography (CT) at 5 and 60 months after the operation and compared them by calculating growth rates...

PURPOSE: Dental implants have been shown to have predictable success, but esthetic complications often arise. To reduce tissue shadowing from titanium, zirconia abutments may be used; however, the literature suggests that the use of zirconia leads to greater destruction of the implant interface that may result in biological complications such as titanium tattoos and heavy metal toxicity. Previous studies have examined the mechanical aspects of this implant/abutment relationship, but they have not accounted for the corrosive degradation that also takes place in the dynamic environment of the oral cavity...
