dental implants are usually placed by sequential set of drills which could increase the time of the surgery and could raise the temperature of the osteotomy preparation so a new drill was designed to place the implants fast and easy way

Dental implant success is evident nowadays with the predictable functional and aesthetic results obtained . Simplified techniques and approaches are preferred for the convenience of both the patients and operators . Current research is focusing on decreasing the number of instruments used, shortening of the operation time and performing flapless approaches for implant placement whenever possible. This is done to reduce the postoperative complaints, such as pain, swelling and bleeding; thus decreasing the need for analgesics and minimising the occurrence of morbidity .

Inclusion Criteria:

• The inclusion criteria :

  • implant recipient sites free from any pathological conditions.
  • Patients who were cooperative, motivated and hygiene conscious were selected.
  • non smoker patients

• exclusion criteria :

  • Patients unable to undergo minor oral surgical procedures
  • patients with a history of drug abuse or catabolic drugs were not included.
  • Patients with a history of psychiatric disorder and those with unrealistic expectations about the aesthetic outcome of implant therapy were also excluded.
  • Patients with insufficient vertical inter-arch space, on centric occlusion, to accommodate the available restorative components .
  • Uncontrolled diabetic patients
  • Patient who had any systemic condition that may contraindicate implant therapy (impaired wound healing - bleeding disorders
  • patients who had any habits that might jeopardise the osseointegration process, such as heavy smoking and alcoholism.
  • Patients with para-functional habits that produce overload on the implant, such as bruxism and clenching were excluded.

after using the single drill compared with the sequential drill all the implants checked for osseointegration , mobility and bone loss after function
