Platelet rich plasma grafting technique combined with trans-sinusal post-extractive implants placement in the posterior maxilla: a technical report and brief literature review.

The atrophic posterior ridges are usually characterized by poor bone quality and quantity: this situation requires the use of bone regenerative techniques. Other alternative surgical approaches are investigated. Nowadays the use of trans-sinus implants offers some advantages due to its feasibility. Today, bone grafting may be practical, but depends on many factors, such as the type of bone graft used (autogenous, alloplastic, or xenograft), host response, age of the patient, various complications associated with grafting procedures, infection, and, most importantly, the time spent while the grafted material matures and is taken up by the bone. So, this case report describes the feasibility of an alternative surgical technique associated to PRP (Platelet Rich Plasma).

New trends in adjunctive treatment and diagnosis in medication-related osteonecrosis of the jaw: A 10-year review.

Medication-related osteonecrosis of the jaw (MRONJ) is a major disease under study for over the last twenty years. Different classifications have been proposed and many therapies for the different stages have been applied. The evolution of treatments lead to an increasingly conservative approach. Numerous adjuvant treatments have been proposed in the last decade. All these complementary treatments have been proposed mainly to resolve or reduce the painful stress, predominantly caused by bacterial infection, simplifying the wound healing process and improving patients' compliance. Nowadays "secondary" treatments, such as autologous platelet concentrates (APCs, more specifically PRP, PRGF or PRF), hyperbaric oxygen (HBO), Auto/tetracycline fluorescence-guided bone surgery (AF-GBS/TF-GBS), medical drugs like teriparatide or the combination between pentoxifylline and tocopherol, fluorodeoxyglucose positron emission tomography (FDG-PET), laser and/or low-laser therapy and ozone therapy are more or less well documented and known considering their clinical effectiveness. The aim of the present review is the evaluation of the quantity and quality of scientific studies concerning this specific topic.

Laser lingual frenectomy: basal eutonia achievement by natural homeostatis.

The aim of present study is a macro evaluation of adjustment to allow homeostasis before and after frenectomy. Macro analysis was done on 7 pediatric patients tested firstly simple surface elettromyography (EMG) to evaluate masticatory muscles, secondly the Romberg's test to assess the posture and thirdly cephalometric analysis according to Giannì and Rocabado to assess orthodontic variations. The frenectomy was performed with diode laser (wavelength 890 nm). Pre-frenectomy EMG outcomes indicate a clear masticatory muscular imbalance with a different electrical activity compared to physiological standard values and functional basal balance. Results after frenectomy EMG show a normalization of basal values with an improvement of mandibular posture. Depending on cephalometric analysis, outcomes reveal a tendency to normalize the cervical lordosis, previously altered. Ultimately, pre-frenectomy Romberg's test shows initial instability in the static posture, which decreases after frenectomy. In conclusion, the short lingual fraenum not only has static correlations with the oral cavity but also dynamic connections with the cervical posture and muscular basal organization. So, homeostasis includes macro alterations involving muscular tone and bone position. Frenectomy could favor the restoration of the basal eutonia achieved by a natural homeostasis.

Zygomatic implants supported rehabilitations in atrophic maxilla: sinus complications, radiological, periodontal and prosthodontic evaluations: a one year follow up retrospective longitudinal study.

The rehabilitation of maxillary bone atrophy represents one of the main challenges of modern oral implantology. The use of zygomatic implants in the prosthetic rehabilitation of the patient affected by severe maxillary bone atrophy is another therapeutic alternative, not exempt from complications. The present study included 19 patients with edentulous maxillae who were treated between 2013 to 2015 with at least two zygomatic implants at the Department of Maxillofacial Surgery, Verona, Italy. The purpose of this retrospective longitudinal study was to evaluate sinus complications and radiological, periodontal and prosthetic evaluations of zygomatic implants technique in severe atrophic. Implant-prosthetic rehabilitation of the upper jaw edentulous severely atrophic using zygomatic implants represents one safe and repeatable technique. In terms of implant survival from our study showed an implant CRS (common reporting standard) of 98.5% and a prosthetic CRS 100% with a mean follow-up period of 19.2 months (range). Both recorded data are superimposed on major reported studies in literature.
