Bone Grafting for Dental Implants: When You Need It

Why bone grafting is so common

When you lose a tooth, the jawbone that used to support it slowly shrinks — a natural process called resorption. The longer a tooth has been missing, the more bone has been lost.

• 3–6 months after tooth loss: 25% of bone width can be gone
• 1 year: 40% loss is common
• 5+ years: 60%+ loss, often insufficient for an implant without augmentation

Bone grafting rebuilds what time has taken so an implant has enough support.

Types of graft

Minor socket preservation

At the time of tooth extraction, we place graft material into the socket to preserve bone while it heals. Cost: AED 800–1,500. Avoids bigger grafts later.

Minor graft at implant placement

Small amount of graft placed alongside the implant to cover any exposed surface. Cost: AED 1,500–3,500. Common, minor addition to surgery.

Sinus lift (upper molars)

The sinus cavity in your upper jaw sits close to where molar roots used to be. When bone is very thin below the sinus, we lift the sinus floor and place graft material. Cost: AED 6,000–9,000 (lateral window) or AED 3,500–5,500 (internal lift).

Block graft

Larger defects need a block of bone — either taken from another site in your mouth or from a donor (allograft). Cost: AED 6,000–12,000. Healing: 6 months before implant.

Ridge expansion

When the jaw is narrow side-to-side, specialised instruments gently expand it and graft is placed into the expanded space. Often combined with implant placement.

Where does graft material come from?

• Autograft: your own bone (best biology, needs a second surgical site)
• Allograft: sterile donor bone (most common — predictable, no extra surgery)
• Xenograft: processed bovine bone (widely used, strong scaffolding, slow to turn over)
• Alloplast: synthetic material (no biological origin)

At Paradise Dental we most often use allograft or xenograft, sometimes mixed — these have excellent long-term data.

Healing time

• Minor graft with implant: no extra wait (integrates while implant heals)
• Socket preservation before implant: 3–4 months
• Sinus lift (small): 4–6 months
• Sinus lift (large) or block graft: 6–9 months

What to expect during recovery

• Swelling for 3–5 days (more than implant-only surgery)
• Mild discomfort, well-controlled with painkillers
• Soft diet 1–2 weeks depending on graft size
• No blowing your nose hard for 2 weeks after a sinus lift
• Antibiotics and a medicated mouthwash are standard

Success rates

• Minor grafts with implant placement: 95%+ success
• Sinus lifts: 94–97% implant success (sinus lift itself is highly predictable)
• Block grafts: 90–95% (larger procedures have more variables)

Smoking, uncontrolled diabetes, and poor hygiene are the main factors that reduce these rates.

Do I always need a graft?

No. If you have plenty of bone already, or lost a tooth recently and got the socket preserved, you can go straight to implant placement. A 3D CBCT scan tells us precisely.
