Edentulous Atrophic Jaws

What are they?

Atrophic oedentulous jaws refer to a condition where the jawbone has suffered significant bone loss and resorption due to long-term tooth loss or other factors. This loss of bone volume can result in a sunken appearance of the face, compromised oral function and difficulty in wearing conventional removable dentures.


Several factors contribute to the development of atrophic oedentulous jaws, including:

  1. Long-term tooth loss: When teeth are missing for a prolonged period, the underlying jawbone may begin to resorb due to lack of stimulation.
  2. Periodontal disease: Severe gum disease can lead to destruction of the supporting bone around the teeth, contributing to bone loss.
  3. Trauma or injury: Trauma or injury to the jaws can result in bone loss and affect the stability and integrity of the jaws.
  4. Genetic or developmental factors: Some individuals may have a genetic predisposition to bone loss or developmental abnormalities that affect the structure of the jaw.


Advanced oral rehabilitation techniques are available to restore the function and aesthetics of atrophic oedentulous jaws. Some common treatment options include:

  1. All-on-4 dental implants: All-on-4 is a technique that involves placing four dental implants strategically in the jawbone to support a full arch of prosthetic teeth. This innovative approach provides a stable, fixed prosthesis that restores chewing function and improves aesthetics.
  2. Elevation of the maxillary sinus: In cases where the upper jaw has suffered significant bone loss, a sinus lift procedure can be performed. This procedure involves elevating the sinus membrane and adding bone graft material to increase the height and bone volume of the jawbone in the posterior region. It creates a suitable base for implant placement.
  3. Lateralisation of the inferior alveolar nerve: When the inferior alveolar nerve, which provides sensation to the lower jaw, interferes with implant placement due to severe bone resorption, a lateralisation or repositioning of the nerve can be performed. This procedure involves moving the nerve to a more favourable position, allowing for implant placement and subsequent rehabilitation.
  4. Bone regeneration: Bone grafting procedures may be required to augment the jawbone in areas with significant bone loss. Bone grafts, either from the patient's own bone or from synthetic materials, are placed in the deficient areas to promote new bone growth and increase the stability of dental implants.
  5. Customised implants: In complex cases where conventional implant options are not suitable, customised implants can be considered. These implants are custom designed and manufactured based on the individual's jaw structure, ensuring optimal fit, stability and aesthetics.
