What is 'Ridge Augmentation' - Bone Grafting

Ridge augmentation restores the width, height, and angulation of a narrow or angled alveolar ridge, ensuring a stable, aesthetic foundation for dental implants.

Ridge augmentation rebuilds jawbone when the alveolar ridge is too narrow (5.6 mm) or at a severe angle (45°), making implants unrestorable (Figs. 1, 2). In this case, the tooth was gently extracted to preserve adjacent bone. Bone grafting widened the ridge to 10.8 mm and corrected the angulation to 20° (Fig. 3). With a rejuvenated ridge, the implant was preplanned and placed in an ideal position beneath the temporary crown (Fig. 4).

Frequently Asked Questions

Why is ridge augmentation necessary?

A narrow or angled ridge can jeopardize implant stability and aesthetics; augmentation restores proper dimensions.

How long does bone grafting take?

Healing typically takes 4-6 months before implant placement is possible.

Is grafting painful?

Local anesthesia and sedation options keep you comfortable; postoperative soreness is minimal.

Can implants be placed simultaneously?

In some cases, yes - if sufficient primary stability is achieved in the grafted bone.
