Bone and Gum Grafting

Bone and Gum Grafting

Bone Grafting for Dental Implants at Perth Implant Dentistry

Dental implants are a proven and successful way of replacing missing teeth (or teeth that need removal) effectively and cosmetically. Dental implants are placed into the supporting jaw to act as a replacement tooth root, allowing a crown (the tooth part above the gums) to be attached.

However if you need dental implants, you may not always have the required bone volume to support implant placement. This is because the area may have shrunk away (atrophy) as a result of the missing tooth, or as a result of dental infection or oral surgery. If this sounds like you, then bone grafting (bone augmentation) can provide a solution.

Bone grafting is a very common procedure at our clinic, and it can be performed efficiently and comfortably for patients, under the comfort of our sleep dentistry (IV sedation) technique.

Several methods of grafts (and their alternatives) are performed by our implant dentists, and we will advise which options are most suitable for you:

Conventional Bone Grafting Methods

These techniques generally require a few months of ‘maturation or integration’ to take place after the procedure, before an implant can be placed:

  • Particulate – Small chips of substitute (or the patient’s natural from a nearby area in the jaw) are used. Substitute options include materials from human, animal and laboratory sources, and provide a scaffold to allow in-growth into the patient’s natural jaw structure. Some substitute materials used in our clinic include Bio-Oss, MinerOss, 4-Bone, BondBone and Bio-Oss Collagen.
  • Block bone graft – Some bone is taken from the back or front of the lower jaw and attached to the deficient (recipient) site.
  • Block bone graft – Some bone is taken from the back or front of the lower jaw and attached to the deficient (recipient) site.

Alternative methods

These techniques often allow implants to be placed immediately without any delay or having to wait for the grafts to mature:

  • These techniques often allow implants to be placed immediately without any delay or having to wait for the grafts to mature:
  • Bone spreading/splitting – The deficient area is divided and expanded to allow the implant to fit.
  • Short implants – Our clinic has expertise and experience with the use of particular brands of short implants which can fit in small areas and still provide a strong foundation for teeth. Dr Misagh Habibi is compiling clinical data studying the results of this technique.
  • All-on-4 or Zygomatic implants – Where multiple teeth (or all teeth) require replacement, these methods often allow reconstruction to be successfully performed immediately and effectively without any grafting.
  • Sinus elevation/sinus lift – Even in severe loss conditions, the sinus spaces in the upper jaw can be modified to create large amounts of healthy area perfect for dental implants. This is a very predictable and surprisingly comfortable way to create abundant amount of bone even in very atrophic upper jaws.

Gum Grafting Procedures

Procedures to regenerate or modify the soft tissues in the periodontal area, such as gum grafting, are often called periodontal plastic surgery procedures.

Dr Habibi can discuss whether gum grafting is suitable for you. Before any grafting is considered or carried out, we would make sure that the area is free from any disease (periodontitis) and that home hygiene is on track. This is to ensure the graft recipient site is healthy and free from inflammation.

There are several types of gum grafting and contouring procedures available including:

  • Connective Tissue Graft (tunnel technique): A strip of tissue is taken from below the palate, and used to bulk and graft the tissue in the defective site.
  • Alloderm (Acellular Dermal Matrix) Graft: A donor-based tissue matrix is used instead of the patient’s own tissue, in order to avoid a second incision and wound for healing.
  • Free Gingival Graft: Full thickness gum is isolated from the palate and used to replace the missing tissue.
  • Coronally repositioned flap: The area is lifted and sutured into a new position.
  • Vestibuloplasty – Muscle attachments and tissue tensions acting on areas that are thin or delicate are relieved to prevent further recession.
  • Leukocyte and Platelet Rich Fibrin (L-PRF): A special substance high in growth factors, fibrin and white blood cells is made from the patient’s own blood in our surgery, and used to close or help augment tissue defects.
