Bilateral reconstruction of the mandibular body with symphyseal preservation using a single fibula free flap: operative technique

Mandibular osteonecrosis may occur in 5% of the patients who undergo radiotherapy for the treatment of head and neck malignancies. Resection and microvascular reconstruction is the treatment of choice in complicated osteoradionecrosis, however multifocal presentation may complicate the management of the disease given the poor quality and limited availability of adequate recipient vessels

Assessment of Peri-Implant Soft Tissues Conditions around Short and Ultra-Short Implant-Supported Single Crowns: A 3-Year Retrospective Study on Periodontally Healthy Patients and Patients with a History of Periodontal Disease

The aim of this retrospective study was to evaluate implant survival, marginal bone loss and peri-implant complications in 326 short and ultra-short implants. Implants were placed in the maxillary and mandibular posterior regions of 140 patients with (PP) and without (NPP) a history of periodontal disease. Clinical and radiographic examinations were performed at 3-year recall appointments. The 8.0, 6.0 and 5.0 mm-length implants placed in PP and NPP were respectively 43.75% and 38.46%, 35.10% and 34.19%, 21.15% and 27.35%; 325 implants (one early failure) were rehabilitated with single crowns in 139 patients. Overall implant survival after 3 years of follow-up was 97.55%, 98.08% and 96.61% for PP and NPP (p = 0.46). Crestal bone level variations were not statistically different among PP and NPP; 15.41% of implants presented signs of mucositis, 14.71% and 16.67% in PP and NPP (p = 0.64). Setting the threshold for bone loss at 2 mm after 36 months, peri-implantitis prevalence was 2.2%, 1.96% and 2.63% in PP and NPP (p = 0.7). Overall implant success was 82.39%, 83.33% and 80.7% for PP and NPP (p = 0.55). Short-term outcomes suggest that short and ultra-short locking-taper implants can successfully be restored with single crowns in the posterior jaws both in PP and NPP

The skin rejuvenation associated treatment-Fraxel laser, Microbotox, and low G prime hyaluronic acid: preliminary results

Minimally invasive facial rejuvenation procedures reached an all-time high in the 2016. This reveals a growing interest in a smoother, younger, and tighter look accessible using the esthetic medicine tools like botulinum toxin and dermal filler injections, laser, and microdermabrasion. Forty-five patients from 35 to 52 years old (medium age 43.8), 38 women and 7 men underwent 5 sessions of Fraxel laser, 1 session of very low G prime HA, and Microbotox injection treatments from January 2016 and January 2017, were included in this study. In this study, we demonstrated that the usage of three treatments together, like mBTX, Volite, and Fractional laser, have a better result despite every single technique alone. The clinical result showed 98% (44 patients, 6 males, 38 females) of the patients had a smoother skin surface, brighter, more hydrated, and elastic skin; 68% of our patients (31 patients, 5 males, 26 females) showed less skin defects and staining as well as less small wrinkles, thanks to Fraxel laser treatment; 98% (44 patients, 6 males, 38 females) showed tighter skin with less sebaceous gland secretion. The aim of this study was to demonstrate that the combination of three techniques acts better and faster than single treatment to contrast facial aging and to improve skin texture and quality

"Dynamic Canthopexy" Drill Hole Canthal Repositioning

Background: Canthopexies can be performed to modify the eye slant, both when the lateral canthus is lower than the medial one (congenital defect) or in case the patient asks for an almond-shaped eye (cosmetic indication).Objectives: This peculiar type of canthopexy can be defined as "dynamic canthopexy," meaning that the lateral canthus is released from its original insertion and raised to a higher position. The goal of this study is to demonstrate the differences and the efficacy of the dynamic cantoplasty.Methods: The authors reviewed 30 patients treated with a "dynamic canthopexy" between January 2005 and March 2015. Eighteen patients were affected by true downslanting palpebral fissure, and 12 patients had a normal eye shape but were wishing for a more "Asian" look. Dynamic canthopexy involves a total modification of the canthal suspension system and its careful reconstruction at a higher level inside the orbital rim. To obtain a permanent result, canthal ligament and tendon had to be anchored to drill holes in the orbital rim bone with nonabsorbable sutures. Symmetry was very carefully assessed. The average surgical time was 1 hour.Results: This surgery proved extremely effective in all cases. Patients must be warned, though, that an initial hypercorrection is necessary to achieve the desired canthal position. About 6 months after surgery the result of this operation can be considered permanent. Severe complications are rare.Conclusions: Dynamic canthopexy can provide stable correction of anti-Mongolian slant. It can also be effectively employed to obtain permanent slant eyes when required by purely cosmetic patients. If precisely carried out, this technique can yield very rewarding outcomes

Microsurgical reconstruction of the mandible in a patient with evans syndrome: a case report and review of the literature

In this report, we describe the first successful case of microvascular free tissue transfer in a patient with Evans Syndrome (ES), a rare form of idiopathic thrombocytopenic purpura (ITP) and associated autoimmune hemolytic anemia (AIHA). Microvascular surgery in the setting of ES is likely to have higher complication rates because of the increased risk of postoperative bleeding and free flap thrombosis. The case presented here opens up to the feasibility of microvascular reconstruction of patients with coagulation disorders like ES. Every effort should be made to control for hemolytic, thrombocytopenic, and thrombophilic states associated with ES. In the absence of evidence-based treatment guidelines for ES, personalized treatment protocols with high-dose corticosteroids, immunoglobulin, and postoperative anticoagulation regimen are highly recommended

Apps for oral hygiene in children 4 to 7 years : fun and effectiveness

Nowadays apps in preschool age are largely used in learning improvement. The aim of this work was to test effectiveness of apps in improving oral hygiene in children patients aged from 4 to 7 years and evaluating correlation between parents educational attainment and children oral hygiene. 100 patients aged from 4 to 7 years were randomly assigned by an external office in the study group (SG: 32 females, 18 males) and in the control group (CG: 28 females and 22 males). Plaque index (PI) and carious lesions localisation were detected. At baseline all patients and one of the parents were instructed at chair-side about the proper oral hygiene techniques. SG patients were also given app as an aid in oral hygiene practice. Follow-up was 12 months. Measurements were made every three months at chair-side visits. Information about children compliance in oral hygiene and educational level of parents were obtained by questionnaires at t0 and after 12 months. SG patients showed stronger oral hygiene and PI lower than those in CG. Questionnaire showed higher compliance of SG patients and parents educational level seemed to affect children oral hygiene. Apps in children allowed achieving encouraging results with improvement of oral hygiene and health

Implementing post-orthodontic compliance among adolescents wearing removable retainers through Whatsapp: a pilot study

Purpose: To determine whether the use of social media is useful in improving compliance and follow-up attendance among patients wearing retainers after orthodontic treatment. Patients and methods: Sixty post-orthodontic patients (aged 16-19 years), randomized in two groups: follow-up supported by participation in WhatsApp chat group (SG), and Control Group (CG). All patients were scheduled for quarterly check-ups for monitoring of orthodontic stability by measurement of intercanine width at the beginning of the study (t(0)) and every 4 months t(1), t(2), t(3)) for 1 year of observation. Patients in the SG additionally participated in a WhatsApp chat group, where they would send, on a weekly basis, snapshots showing his/her occlusion. Every month, the orthodontist acting as the moderator awarded the best five snapshots by publishing a ranking in the chat. Results: Participants in the SG featured smaller changes from the intercanine widths at baseline (at debonding) compared to the CG patients at all times during 1 year of follow-up. Follow-up attendance was regular in both groups in the first 8 months of follow-up. After that, patient compliance decreased in the CG, with eight patients missing check-up appointments. Conclusion: Engaging adolescent patients directly through WhatsApp activity seems to increase regularity in wearing removable retainers, attendance to follow-up schedule, and yield better long-term outcome in terms of orthodontic stability and compliance

The 'Alternating Osteotome Technique': a surgical approach for combined ridge expansion and sinus floor elevation. A multicentre prospective study with a three-year follow-up

The aim of this multicentre prospective study was to evaluate the efficacy and safety of a surgical approach based on a novel osteotome technique, in order to obtain both alveolar ridge expansion and sinus floor elevation. Partially edentulous patients requiring an implant-prosthetic rehabilitation with a fixed prosthesis in the posterior maxilla were included in this study according to pre-established inclusion and exclusion criteria. All implants were placed after site preparation with the 'Alternating Osteotome Technique', which consists of the use of alternating concave and convex osteotomes. After a 4 to 6-month healing period, all implants were restored with a definitive fixed prosthesis. Clinical and radiographic examinations were scheduled over a 36-month follow-up of functional loading according to a well-established protocol. Statistical analysis was used to detect any significant differences or correlations (P = 0.05). Seventy-six patients were consecutively treated with a total of 120 implants in three different centres. The mean ridge expansion and sinus floor elevation were 1.8 ± 0.3 and 2.5 ± 0.7, respectively. After three years of functioning, the implant success rate was 99.1% since one implant had failed and the mean marginal bone loss was 0.6 ± 0.3 mm. No complications occurred during the intraoperative and postoperative periods. All parameters analysed were stable and steady throughout the three-year follow-up. The 'Alternating Osteotome Technique' enables the dental surgeon to achieve an adequate implant osteotomy with limited ridge expansion and sinus floor elevation, increasing modestly the vertical and horizontal dimensions of the alveolar crest but reducing significantly the risk of surgical complications

Single-Crown, Short and Ultra-Short Implants, in Association with Simultaneous Internal Sinus Lift in the Atrophic Posterior Maxilla: A Three-Year Retrospective Study

As the atrophic posterior maxilla often presents serious limitations for dental implant procedures, a minimally invasive technique was proposed. The study aimed to retrospectively evaluate the outcomes of short and ultra-short locking-taper implants, placed in combination with a modified osteotome sinus floor elevation procedure (internal sinus lift technique) in the posterior maxilla. A total of 31 patients received 51 locking-taper implants. Clinical and radiographic examinations were performed before treatment, at loading time, and after three years. Seven implants of 8.0 mm, 23 implants of 6.0 mm, and 21 implants 5.0 mm in length were rehabilitated with single-crown restorations. Implant survival at three-year follow-up was 96.08%. Pre-operative residual crestal bone height of 5.2 (1.41) (median (interquartile range)) mm increased to 7.59 (1.97) mm at the 36-month follow-up, with an average intra-sinus bone height gain of 3.17 ± 1.13 (mean ± standard deviation) mm. Mean peri-implant crestal bone loss was 0.29 (0.46) mm and mean first bone-to-implant contact point shifted apically to 0.12 (0.34) mm. It can be suggested with confidence that implants used in the study, placed in conjunction with an internal sinus floor elevation technique, can be restored with single crowns as a predictable treatment for the edentulous regions of the posterior maxilla
