Immediate, early, and late implant placement in first-molar sites: a retrospective case series.

Purpose: To review the clinical outcomes of immediate, early, and conventional single-tooth implant placement in mandibular or maxillary first molar sites.

Materials And Methods: The charts of patients treated consecutively for first molar replacement according to unconventional (immediate = group 1, early = group 2) or conventional (late = group 3) surgical protocols were examined. All available clinical parameters were reviewed to calculate implant survival and success rates according to well-established criteria.

Double pathological fracture of mandibula caused by actinomycotic osteomyelitis: a case report.

Actinomycosis is an uncommon chronic granulomatous infection that cause formation of abscesses and cutaneous fistula. In mandibular actinomycosis the alveolar bone and mandibular body are usually not involved and the pathogenetic mechanisms of the actinomycotic infiltration is unknown. The patients usually report pain at the alveolar arch with development of a purplish-red swelling firmly attached to the mandibula; the fibrous tissue produces the continued development of new cutaneous fistulas with oncoming pus-secretion.
