Speed of sound measurements in mandibular and phalangeal bone during growth
2001
The micromechanical and elastic properties of bone, its structural maturity and, indirectly, mineral density are important factors for the planning and assessment of orthodontic and/or jaw orthopaedic treatment. This clinical study was undertaken to evaluate age-related changes in the anterior mandibular body. The speed of sound (SOS) has demonstrated age dependency in various peripheral bones and has been proposed as an alternative method for investigating bone parameters without the use of radiation. The ultrasound transmission velocity was measured in 184 healthy subjects (93 females, 91 males; mean age 17.6 +/- 13.7 years). According to the statistical analysis, the data did not reveal …
Envelope approach for onlay bone grafting : preliminary surgical and prosthetic results
2009
Minimally invasive surgery principles have been applied to preprosthetic-implant surgery, and an adequate presurgical planning reduces morbidity in both harvesting and stabilization of the bone grafts. Objective: A new ?envelope? approach for onlay bone grafting at the alveolar process is presented, this avoids releasing incisions yet allowing adequate reconstruction of the defective site. Study design: To be included in the study the patient had to have an antero-posterior defect of the alveolar crest. Patient age and sex, location of the defect, type and size of graft, and complications appeared during follow up were recorded. Results: Ten consecutive patients (4 men and 6 women) have bee…
Alternative intraoral donor sites to the chin and mandibular body-ramus.
2017
Background Provide a review of alternative intraoral donor sites to the chin and body-ramus of the mandible that bring fewer complications and that may be used to regenerate small and medium defects. Material and Methods A review was conducted using the search engine PUBMED and looking manually into scientific journals. Results From the 35 articles included, 6 corresponded to the coronoids, 3 corresponded to the zygomatic body, 5 corresponded to the anterior maxillary sinus wall, 3 corresponded to the zygomatic alveolar process, 2 corresponded to the incisive fossa, 2 corresponded to the anterior nasal spine, 2 corresponded to the palatal region, 5 corresponded to the tuberosity, and 7 corr…
Spontaneous bisphosphonate-related osteonecrosis of the left hemi-mandible: Similarities with phossy jaw.
2013
Intravenous bisphosphonates (BP) play a key role in the treatment of bone metastases. As a long-term side effects BP, a form of avascular osteonecrosis of the jaw has been reported. Although, invasive oral local procedures are often present in clinical history of patients suffering from bisphosphonates-related osteonecrosis of the jaws (BRONJ), about up to 50% of BRONJ are spontaneous. We report a case of a 68-year-old female with a spontaneous wide bone sequestration of the left mandibular body onset after infusion of zoledronic acid for 18 cycles for osseous metastasis due to metastatic anaplastic thyroidal carcinoma. Surprisingly the clinical aspects of the patient initially reminded us …
Complications in the use of the mandibular body, ramus and symphysis as donor sites in bone graft surgery: a systematic review
2015
Background To develop a systematic review by assessing and comparing the different complications that occurs in bone graft surgery using the mandibular body, ramus and symphysis as donor sites. Material and Methods In order to respond to the following question, a systematic review was developed: does the use of intraoral mandibular body and ramus as donor sites in bone graft surgery, produce fewer and less severe complications in comparison to the use of the mandibular symphysis in patients that present bone resorption that needs augmentation using autologous grafts? The review was carried out between January 1990 and 2015, during which only clinical essays with a minimum follow-up period o…
