Septal Bone Expansion Using Osseodensification Versus Piezoelectric Implant Site Preparation

Septal Bone Expansion Using Osseodensification Versus Piezoelectric Implant Site Preparation for Immediate Implant Placement in Mandibular Molars [Randomized Clinical Trial]

: Implant placement in the inter radicular septum is usually considered the best option for an immediate molar implant, not only in terms of correct 3D positioning, but also regarding implant survival, Osseodensification was shown to enhance implant primary stability, due to the compaction auto-grafting and the associated spring-back effect. Piezoelectric implant site preparation (PISP) has been proposed as an alternative technique to improve surgical control, safety, and bone healing response Aim of the work: To evaluate and compare stability changes using insertion torque values (ITV) and Implant Stability Quotient values (ISQ) for immediately placed implants in molar septum using Osseodensification technique and Piezoelectric implant site preparation (PISP) technique.

Inclusion Criteria:

• Adult patients with hopeless mandibular molar teeth in the posterior region in need of implant placement .
• A fully intact facial bone wall at the extraction site.
• Systemically healthy, received no head and neck radiation for cancer treatment.
• Absence of periapical pathologies or suppuration at the time of installing the implants.
• Septal bone after atraumatic extraction not less than 3 mm.

Exclusion Criteria:

• Systemic conditions that would prevent successful healing or implant osseointegration; examples are uncontrolled Diabetes Mellitus, metabolic bone disorders, autoimmune diseases, or Bisphosphonate therapy.
• Heavy smoker patients.
• Presence of preapical bone loss related to extracted tooth.
• Patient is not indicated for immediate implant placement
