1/3. Unhealed extraction sites mimicking TMJ pain.A case of unhealed extraction sites in the mandible is described, including clinical, radiographic, and biopsy findings. The subject was treated for TMJ disease in the past but still had related signs and symptoms and facial pain.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/3. IMZ implants placed into extraction sockets in association with membrane therapy (Gengiflex) and porous hydroxyapatite: a case report.A buccal plate destroyed by the inflammatory process as a result of a longitudinal root fracture was completely restored by the combined use of an IMZ implant placed in the alveolus of the fractured maxillary central incisor and the principles of guided tissue regeneration. A Gengiflex membrane was used to cover the implant, and porous hydroxyapatite was used as grafting material. At the 6-month reentry, the defect around the implant was completely filled by mineralized tissue.- - - - - - - - - - ranking = 0.8keywords = extraction (Clic here for more details about this article) |
3/3. Exogenous estrogen may exacerbate thrombophilia, impair bone healing and contribute to development of chronic facial pain.A 32 year old white female, in apparently good health, failed to respond to conservative wound care for alveolar osteitis after a routine mandibular first molar extraction. curettage and biopsy of necrotic alveolar bone from the #30 socket escalated her pain such that hospitalization was necessary for pain management with intravenous morphine. Twelve months prior to admission she had been placed on exogenous estrogen (Premarin, 0.625 mg/day) after a partial oophorectomy. While hospitalized, she was found to have resistance to activated protein c (APCR). Premarin was discontinued. After discharge, weekly changes of an antibiotic impregnated dressing allowed for progressive regeneration of bone and epithelium with gradual reduction in her pain. She was found to be heterozygous for the mutant factor v Leiden, a heritable factor for increased tendency to form thrombi, so-called thrombophilia. We speculate that the exogenous estrogen administration exacerbated the thrombophilia associated with the factor v Leiden mutation by compounding the patient's resistance to activated protein c thereby contributing to her development of osteonecrosis and severe alveolar neuralgia.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
