Dental Implant Insertion

Dental Implant body is installed with the recommended insertion torque. Appropriate insertion torque is needed to avoid too much compression of the bone. Excessive compression on the bone blocks blood supply and may lead to necrosis of the implant bed.

Aesthetic Dental Implants

These are the Guidelines in Treatment of Aesthetic Implant Cases, according to Dr. Sherwin Villareal, Resident Oral Implantology, Ashman Department of Periodontology and Implant Dentistry, New York University, College of Dentistry.

1. Pre-surgical planning
2. Site development
3. 3-D Implant positioning
4. Soft tissue management
5. Provisionalization
6. Prosthetic management

Implant Bed

Bone quality for the 3rd implant is assessed under the raised full thickness flap. Drilling should follow the same desired RPM ang copious irrigation preferably with an NSS refrigerated the night before the surgery.

Rehabilitation with Dental Implants

According to Dr. Sherwin Villareal – NYU, “The establishment of optimum and predictable esthetics is one of the most important and challenging aspects of rehabilitaion with dental implants.” Esthetic rehabilitation has to be predictable implying reproducibility and stability of the outcome in both short and long term. Achieving these characteristics depends on the interactions between multiple valuables namely biological, surgical, prosthetic and implant design.

Dental Implant Design for Immediate Placement

Dental Implants which are favorable to immediate placement after extraction are as follows:

Tapered Implant
For immediate replacement after extraction, initial fixation is very important because the contact area between fixture and bone is inevitably small. Therefore, a tapered implant with has excellent initial fixation is more favorable than the straight type.

Implant Favorable to Bone Grafts
In case of placement after extraction, Guided Tissue/Bone Regeneration or GBR is frequently performed because of the dehiscence or space between the fixture and alveolar bone. Therefore, an implant design with a proper surface treatment for its alveolar ridge should be selected.
