Article Synopsis
- MRI of the brain is commonly used for patients with neurofibromatosis type 1 (NF1) to monitor intracranial findings, but this study examines the potential benefits of also assessing the jaws during these scans.* -
- A case study involved a patient with NF1 who had a central giant cell granuloma and a neurofibroma in the mandible, revealing distinct progression rates of jaw lesions during a 3-year follow-up.* -
- Including jaw assessment in MRI evaluations for NF1 patients may allow for earlier detection of pathologies, potentially preventing further complications and improving treatment outcomes.*
Follow-up study of implants with turned or oxidized surfaces placed after sinus augmentation.
Int J Oral Maxillofac Implants

Purpose: To compare long-term survival and clinical outcomes of endosseous implants with different surface characteristics in patients with sinus elevation procedures, autologous bone grafting, and delayed implant placement.
Materials And Methods: Implant survival, peri-implant soft tissue conditions, marginal bone level, intrasinus apical bone level, and sinus health were studied in patients subjected to autologous bone graft and delayed placement of implants with turned or oxidized surfaces. After a minimum of 5 years of functional loading, all patients were clinically examined regarding gingival pocket depth (PD) and bleeding on probing (BoP).
Objective: This pilot study was performed to test the hypothesis that an orthodontic oral appliance (OA) that is designed to work against the backwardly directed forces on the upper incisors may counteract the reduction in overjet from these devices.
Materials And Methods: Thirty patients with normal bites, good oral health, and milder sleep apnea were randomized to treatment with either OAs or orthodontic OAs. Bite changes were evaluated on plaster casts and radiographs and by questionnaires after a mean of 2.
The aim of this study was to develop a method that optimizes the reliability of longitudinal radiographic evaluation of small and fast-growing animals, such as the rabbit. Because the use of conventional cephalometric methods, including superimposition of serial radiographs, is more problematic in small animals than in humans, two titanium-alloy screws were placed 10 mm apart in the sagittal crest of the parietal bone in 10 growing New Zealand white rabbits. The anterior screw served as holder for a steel pin that, in turn, secured the fixation of the rabbit's head to a specially designed cephalostat.
