evaluate clinically and radiographically the effect of customized healing abutment on peri-implant osteogenesis following immediate implant placement.

Now a day most people want to make immediate implant after extraction, which save them time and eliminates the need of second surgery. The problem is that the jummping gap between the implant and the bone that needs bone graft, this increase the cost on the patient. In this experiment we tend to evaluate this technique which may help us in growing autogenous bone and stop the need for bone grafting.

The aim of this study is to evaluate clinically and radiographically the effect of customized healing abutment on peri-implant osteogenesis following immediate implant placement.

A clinical trial was carried out on 8 patients (20-40 years old) with freshly extracted mandibular molars. Implants were placed immediately after extraction and a customized healing abutment will be fabricated. Patients were followed up clinically and radio graphically for 6 months.

Inclusion criteria:

• Age range: 20 - 40 years
• Good oral hygiene
• A freshly extracted socket in the mandibular molar area.
• The gap between the implant and the bone will be at least 3-4 mm.

Exclusion criteria:

• Acute infection (periodontitis or mucosal infection)
• Patients on radiotherapy or chemotherapy.
• Alcohol or drug abuse.
• Patient with the systemic disorder (uncontrolled Diabetes mellitus, autoimmune diseases, bone diseases, etc.)
• Smokers.
• Parafunctional habits.
