Faciomaxillary and ocular trauma is a common entity in most emergency and trauma units. We came across a 68-year-old female patient with a history of bull horn injury over the right eye. Examination revealed an empty orbital socket with unreliable perception of light present. Imaging showed that the eye had displaced posteroinferomedially to be lying in the ethmoid air cells in the nasal cavity. Under nasal endoscopic guidance, the eye was reposited back into the orbital socket and conjunctival sutures were taken to stabilize the position...

In this prospective study, 15 patients received 15 variable-thread tapered implants placed in fresh extraction sites in the maxillary esthetic zone and immediately were provisionalized out of occlusion. Of the 15 patients, 11 completed their 2-year follow-up. At 2 years, the success and cumulative survival rates were both 100%, and the mean bone level gain was 0.83 mm. Soft tissue assessment showed no zero esthetic scores, improved papilla indices, and low bleeding on probing and plaque accumulation. Overall, the study implants showed excellent hard tissue, soft tissue, and esthetic outcomes, indicating a healthy tissue response in single-tooth extraction sites in the maxillary esthetic zone...

Esthetic implant therapy can be challenging in the anterior maxilla, and meticulous treatment is often required to deliver optimal esthetics. Close collaboration between surgical and prosthetic team members using the novel approach of prosthetic crown lengthening helped camouflage a shallow implant platform location, providing the proper gingival frame for esthetic restorations. This case report presents an interdisciplinary approach that included ridge augmentation, second-stage crown lengthening, and prosthetic soft tissue manipulation to address an implant placed too shallow in the alveolus of an extraction socket...

The objective of this study was to evaluate the effect of leukocyte platelet-rich fibrin (L-PRF) on immediate implant stability and recovery. A total of 60 immediate implants were evaluated. After the extraction, using split-mouth design, test sockets were coated with L-PRF (L-PRF+) and control sockets were not (L-PRF-). All the implants were followed for 12 months. Results showed a statistically significant difference between the stability of L-PRF+ and L-PRF- implants at 1 week and at 1 month. Mean marginal bone resorption was higher in the control group at 1 year...

Autogenous tooth transplantation (ATT) is a simple and reasonable choice for replacing the missing teeth when a proper donor tooth is available. This report presents a case of successful ATT of a maxillary right third molar for replacement of mandibular right second molar with a concomitant endodontic-periodontal disease. The mandibular second molar was believed to be hopeless due to a severe damage to coronal tooth structure, inappropriate root canal treatment and apical radiolucency. After extraction of mandibular second molar and maxillary third molar (the donor), the tooth was re-implanted into the extracted socket of second molar site...

The current generation of hip resurfacing consists of a metal-on-metal ball and monoblock socket of minimal thickness. Although results in certain patient subgroups have been excellent at up to 15 years of follow-up, other subgroups have had poor results. The hard-on-hard bearing is susceptible to edge-loading conditions and may produce excessive metallic debris; furthermore, other patients have had allergic reactions to the metal byproducts. In both situations, there can be clinical failures from adverse local tissue reactions...

BACKGROUND: Adverse local tissue reactions (ALTR) have been associated with the use of metal-on-metal (MoM) bearings and the monitoring of cobalt (Co) and chromium (Cr) ion levels in blood or serum may be the best way to evaluate in vivo the wear of these bearings. However, the relationship between Co and Cr ion concentrations and the formation of ALTR remains unclear. METHODS: We investigated the relationship between ALTR and serum Co and Cr ion levels and identified the clinical factors influencing the formation of ALTR in patients treated with MoM hip resurfacing arthroplasties...

Mechanical coupling at the interface between lower limb residua and prosthetic sockets plays an important role in assessing socket fitting and tissue health. However, most research lab-based lower limb prosthetic simulators to-date have implemented a rigid socket coupling. This study describes the fabrication and implementation of a lower limb residuum/socket interface simulator, designed to reproduce the forces and moments present during the key loading phases of amputee walking. An artificial residuum made with model bones encased in silicone was used, mimicking the compliant mechanical loading of a real residuum/socket interface...

Mark J Lemos
As a result of emerging technology and techniques developed for anterior cruciate ligament (ACL) reconstruction, it is important to evaluate all aspects of the new procedures. One of these hot topics is retrograde drilling, which leads to inside-out ACL interference screw divergence from ACL sockets created from outside-in. In this paper, the authors look at screw divergence in the femoral tunnel for bone-patella-bone reconstructions performed with an outside-in retrograde drill. The screws are inserted through a separate accessory anterior medial portal, and therefore there is concern on whether or not there is significant divergence compromising their fixation...
