Bone Graft – bone augmentation

A good brand of particulate allograft is Puros Allografts by Zimmer. From its line of allografts for bone augmentation, puros cancellous particulate allograft has become the bone grafting of choice for many dentists.

Cancellous particulate allograft acts as an osteoconductive scaffold for new bone formation. In large volume of applications, studies have shown faster bone regeneration at 6 months than grafts containing sintered bovine bone matrix. While in small volume applications, regeneration of hard bone has been reported as early as 3-5 months.

Cancellous particulate allograft retains osteconductive properties due to preservation of the natural bone matrix collagen and mineral composition, trabecular pattern, and original porosity enabling the ingrowth of vascular and cellular connective tissue.

Perforation in Dental Implant Installation

Perforated Lingual or Buccal There will be no problem if the fixture threads are imbedded in bone.

Perforated Bone Coronally Do a bone graft procedure if fixture threads are exposed at the coronal. Section small amounts of bone, mix with Resorbable Tissue Replacement, then place the bone graft material over the exposed threads.

Dental Implant Torque

For final tightening of the dental implant, torque ratchet is used. It is also used to measure the exact torque of the dental implant. Over threading is also prevented by using the torque ratchet. Over threading could strip all threads in bone.

Dental Implant Fixture Installation

The dental implant fixture mount is attached to the fixture using the open ended wrench. The inner hexagonal surface should fit properly over the fixture head. Match the inner surface of the handpiece connector to the square top of the fixture mount and apply gentle pressure between the components.

When the apex of the fixture is threaded and no longer visible, begin irrigation. Photo credit: Oris Neobiotech

Dental Implant Fixture Parallelism

The direction indicators are inserted into the dental implant site to check and maintain parallelism during preparation.

Poor fixture alignment

If the angle with adjacent fixture is less than 35 degrees, there will be not be a major problem prosthetically.

Dental Implant Drilling Procedure

Copious saline irrigation is required in the use of any drilling instruments. A surgical splint is used to determine dental implant fixture insertion site. In the maxilla, a fixture for 11 or 21, is placed 3 mm from the midline suture line.

After pilot drilling is done, the fixture site is enlarged using a 3.0 mm diameter twist drill. The procedure is important for preparing the implant fixture site to proper depth. The indicator mark on the drill should be level with the bony margin.

Dental Implant supported bridge have the following advantages:

  • It looks, feels and performs similar to natural teeth.
  • Sound adjacent teeth are not compromised to support a bridge.
  • Preserves sorrounding bone.
  • Dental bridge attached securely to dental implants.
  • It prevents resorption of bone.
  • Recurrent wear around abutment is eliminated.
  • Seld esteem of the patient is improved.

Dental Implants will maintain surrounding bone and soft tissue, as well as replace missing teeth.
