简要总结

Alveolar bone atrophy post-extraction has been well documented in the past years. normal healing event results in a minimal loss of vertical height (around 1 mm), but a substantial loss of width in the buccal-lingual plane (4-6 mm). Alveolar socket preservation is thought to deal with this issue as to prevent the loss of alveolar bone dimensions post extraction in the case of delayed implant placement

入选标准

  • Adult patients with hopeless mandibular molars indicated for extraction and implant placement in two stages that indicate socket preservation.
  • Both sexes.
  • No intraoral soft and hard tissue pathology.
  • No systemic condition that contraindicate implant placement.

排除标准

  • Presence of fenestrations or dehiscence of the residual bony Walls after extraction.
  • Heavy smokers more than 20 cigarettes per day .(24)
  • Patients with systemic disease that may affect normal healing.
  • Psychiatric problems
  • Disorders to implant are related to a history of radiation therapy to the head and neck neoplasia, or bone augmentation to implant site.
  • Patients that refuse to be called back for implant placement post extraction.
  • Patients that have exceeded bone resorption surrounding the tooth prior to extraction and require guided bone regeneration.
  • Pregnant Females.
