• 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 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.
