Medication-related osteonecrosis of the jaw: risk factors in patients under biphosphonate versus patients under antiresorptive-antiangiogenic drugs.

Background: Biphosphonate-related osteonecrosis of the jaw (BRONJ) is a potential side effect associated with the administration of bisphosphonates; the aim of this work is to highlight the possible epidemiological differences between two groups of patients affected by medication related osteonecrosis of the jaw (MRONJ) treated at the Center of Oral Medicine, Pathology and Laser Surgery of the Academic Hospital at the University of Parma, Italy, between January 2004 and June 2016.

Methods: Medical charts of 303 patients (214 females and 89 males, mean age: 67 years old) treated at the Center of Oral Medicine, Pathology and Laser Surgery of the Academic Hospital at the University of Parma, between January 2004 and June 2016, were retrospectively analyzed. Patients were divided in 2 groups according to drugs therapy they underwent: group 1 (G1) including patients treated with bisphosphonates alone and group 2 (G2) including patients receiving antiresorptive-antiangiogenic drugs in association with bisphosphonates or antiresorptive-antiangiogenic drugs alone.

Quantification of the amount of dental material removed by selective grinding in wax dentures with photogrammetric measurements.

Background: The use of photogrammetry may be a new method to quantify the amount of artificial dental material removed from the surface of each teeth during the grind procedure (SG). SG is necessary in each denture to reach a correct occlusion. It consists in a refine action on the prosthesis teeth's surface using milling machine tools, aimed to remove the interferences (pre-contacts) between upper and lower teeth during chewing.

Medication-Related Osteonecrosis of the Jaw Around Dental Implants: Implant Surgery-Triggered or Implant Presence-Triggered Osteonecrosis?

Trial Design: This analysis compared the outcome of fresh-frozen versus autologous bone block grafts for horizontal ridge augmentation in patients with Cawood and Howell class IV atrophies.

Methods: Seventeen patients received autologous grafts and 21 patients received fresh-frozen bone grafts. Patients underwent CT scans 1 week and 6 months after surgery for graft volume and density analysis.

Different laser wavelengths comparison in the second-stage implant surgery: an ex vivo study.

The implant surgery consists of two distinct techniques, the transmucosal, also known as "one-stage" and the "two-stage" technique. Lasers represent a possible aid in implant dentistry, especially in the two-stage technique and its main characteristics are represented by a decreased trauma to bone and soft tissues, a reduction of pain as well as a reduction of the risk of postoperative infections. The aim of this study was to analyze in an animal model the thermal elevation induced by four different laser wavelengths (diode, Nd:YAG, Er:YAG, KTP) during the implant uncovering.

Central incisor loss after delayed replantation following avulsion: a contemporary restorative and adjunctive orthodontic management approach.

Delayed replantation of an avulsed tooth may result in rapid root resorption or, more frequently, dental ankylosis with subsequent bone substitution. If this process develop slowly, it is possible to observe that tooth loss is characterized by a well conserved alveolus with regard to bone preservation, particularly in vertical dimension. This clinical case reports a dental trauma of a central incisor in a young boy characterized by tooth avulsion and its delayed replantation.

Nd:YAG laser versus traditional scalpel. A preliminary histological analysis of specimens from the human oral mucosa.

Hyperplastic fibro-epithelial lesions are the most common tumor-like swellings in the mouth. The neodymium yttrium aluminium garnet (Nd:YAG) laser appears to be useful for the surgical treatment of these lesions. Some controversies of laser surgery concern the accuracy of pathological diagnosis as well as the control of thermal damage on the target tissue.
