Brief Summary

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

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • 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.

You may not qualify if:

  • 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.
