Pain and anxiety following the placement of dental implants.
This study investigated pain experience and anxiety following dental implant placement using questionnaires and salivary cortisol measurements. ⋯ Patient self-assessment indicates that implant placement is a mild to moderately painful and anxiety-provoking procedure. Some limitation of daily activities and symptoms are expected to occur, particularly during the first 3 postoperative days.

ReviewThe efficacy of various bone augmentation procedures for dental implants: a Cochrane systematic review of randomized controlled clinical trials.
To test (a) whether and when bone augmentation procedures are necessary and (b) which is the most effective augmentation technique for specific clinical indications. Trials were divided into 3 categories: (1) major vertical or horizontal bone augmentation (or both); (2) implants placed in extraction sockets; (3) fenestrated implants. ⋯ Major bone grafting procedures of extremely resorbed mandibles may not be justified. Bone substitutes may replace autogenous bone for sinus lift procedures of extremely atrophic sinuses. Both guided bone regeneration procedures and distraction osteogenesis can be used to augment bone vertically, but it is unclear which is the most efficient. It is unclear whether augmentation procedures are needed at immediate single implants placed in fresh extraction sockets; however, sites treated with barrier + Bio-Oss showed a higher position of the gingival margin than sites treated with barriers alone. More bone was regenerated around fenestrated implants with nonresorbable barriers than without barriers; however, it remains unclear whether such bone is of benefit to the patient. Bone morphogenetic proteins may enhance bone formation around implants grafted with Bio-Oss, but there was no reliable evidence supporting the efficacy of other active agents, such as platelet-rich plasma, in conjunction with implant treatment.

Accuracy assessment of image-guided implant surgery: an experimental study.
To accurately accomplish the drilling of an implant socket, the use of image-guided navigation has become an option. The aim of this study was to evaluate the 3-dimensional (3D) accuracy of navigation-guided drilled holes. ⋯ The data obtained by this in vitro study demonstrate that the accuracy of navigation-based drilling may be sufficient for clinical practice, particularly in terms of the transferability of preplanned trajectories. However, in vivo clinical trials need to be performed to evaluate the clinical accuracy and treatment quality of navigation-guided interventions.

Case ReportsDistraction osteogenesis in an anterior mandibular bone defect utilizing lingual periosteal release: a case report.
This clinical report presents a modified distraction technique to achieve height in the vector of distraction. The success of distraction osteogenesis depends on both biologic and biomechanical factors. The focus in this case is on correcting the direction of distraction; incorrect distraction direction is a frequent complication associated with distraction osteogenesis in the mandible. ⋯ After osteotomizing a bone segment and slitting the lingual periosteum, the bone segment was advanced anteriorly 4 mm and an extra-alveolar distraction device was applied. This approach allows the distraction device to be placed vertically, thus preventing lingual shift. The newly created alveolar ridge fully met prosthodontic requirements for a predictable outcome.

This study aimed to (1) compare 2 scales in the assessment of first-stage implant surgery, (2) assess the interrater reliability of these scales, and (3) compare self-assessment with observer assessment. ⋯ Both the checklist and the global rating scales provided useful assessment data, and both were considered of value by the assessors and surgeons in providing feedback. The development of assessment and self-assessment skills in implant surgery is necessary if we are to establish a culture of commitment to lifelong learning.
