什麼是All-On-4全口植牙

All‑on‑4 全口植牙是一種以四支植體支撐固定式全口牙橋的重建方式，適用於多顆或全口缺牙、牙周病末期或牙齒無法保留的患者；手術通常在同次拔牙後置入植體並裝上臨時固定橋，利用前牙區較佳骨質與斜植後牙植體減少骨移植需求，加速恢復咀嚼功能與美觀，術前需以 CBCT 評估骨量與全身條件並討論長期維護與風險。

初步評估

The dentist will conduct a comprehensive oral examination, take X-rays or 3D CT scans to analyze the condition of the jawbone, and develop a personalized treatment plan.

初步評估與治療計劃

電腦掃描模擬

After developing an All-on-4 implant treatment plan, if the patient has any teeth that cannot be saved, the dentist will extract them and clean any damaged or infected tissue in the mouth. Next, a computer scan will be used to simulate the implant placement process, allowing the patient to fully understand the expected results of the full-mouth implant treatment.

局部麻醉

There are two main types of anesthesia: local anesthesia is the most common, which only anesthetizes the surgical area, keeping the patient awake throughout the procedure without pain; while sedation (also known as intravenous sedation) is suitable for patients who are nervous or fearful about surgery, as it puts them into a semi-sleep state, making the procedure painless and usually without memory, making the treatment easier and more comfortable.

All-On-4全口植牙步驟 3

局部麻醉

進行手術

The dentist will first make a small incision in the gum line of the upper or lower jaw to expose the alveolar bone. Using a special dental drill, the dentist will create four small holes for the implants. The first two implants are typically placed vertically, while the last two are placed at approximately a 45-degree angle. After each hole is drilled, the dentist will insert the titanium implant into the alveolar bone. Once the implants are in place, the dentist will suture the gum line closed and leave a small hole at the tip of the implant to secure the prosthesis.

Traditional full-mouth dental implants vs. All-on-4 full-mouth dental implants

Surgical methodsAfter implanting an implant into the alveolar bone at the site of the missing tooth, it takes several months for the implant to integrate with the alveolar bone before a proper denture is fitted.Using precise mechanical principles, four implants are inserted into the alveolar bone, and temporary dentures can be fitted on the same day. Once the implants have stabilized with the alveolar bone, permanent dentures will be fitted.
Surgery timeTreatment is usually administered in multiple sessions over a longer period of time.Can be completed on the same day
Number of plantsEight implants were placed in the maxilla and six in the mandible, and the implants were placed in stages.Four to six implants in one jawbone can be completed on the same day.
Bone grafting surgeryBone grafts are usually needed.In most cases, bone supplementation is not necessary.
Treatment costsTraditional costs are relatively expensiveAll-On-4 is reasonably priced.

Common Questions about All-On-4 Full Mouth Implants

如有All-On-4全口植牙問題，可WhatsApp我們，會有牙醫親身回答

Who is not suitable for All-on-4 full mouth implant surgery?

If the patient has a serious systemic disease (such as diabetes or cardiovascular disease, is taking oral/injectable medications for osteoporosis, or is unable to care for themselves), or has a serious jaw problem, additional evaluation or alternative treatment options may be required.

Will I experience pain during All-On-4 full mouth reconstruction?

During All-On-4 full mouth reconstruction, the doctor will perform local treatments inside the mouth to reduce pain or discomfort for the patient during the procedure. Patients may still experience mild pain or discomfort after All-On-4 surgery; the situation varies from person to person. Following the doctor's instructions and taking the medication, the pain from All-On-4 full mouth reconstruction will gradually disappear.


Can you still get cavities after root canal treatment?

Yes! Because teeth lose their nerves and therefore don't feel pain, cavities are easily overlooked, so it's even more important to strengthen cleaning and have regular checkups.

How long does the All-On-4 dental implant surgery take?

The time required for All-On-4 dental implantation varies depending on individual circumstances, the number and location of teeth to be implanted, and the required All-On-4 surgical procedure in Hong Kong. Typically, a unilateral procedure takes approximately 2-3 hours to complete, including suturing and impression taking.

How should one care for and pay attention to the post-operative care of full-mouth dental implants?

Regular inspections:Regular follow-up appointments allow the dentist to check the condition of the implants and promptly identify and address any issues.
It is recommended to have a professional cleaning done every six months.
Dietary precautions:In the initial stages, avoid hard, crunchy, or sticky foods to prevent stress on the dental implants. As recovery progresses, you can gradually resume a normal diet, but you should still pay attention to the texture of your food.
Avoid bad habits:Avoid smoking, as it can interfere with the healing process and increase the risk of infection. Avoid using your teeth to open bottles or bite hard objects to prevent damage to the implant.
Be aware of pain and discomfort:If you experience persistent pain, swelling, or bleeding, contact your dentist immediately.

Can I get All-On-4 implants if I don't have enough bone?

If a patient has insufficient bone mass, surgery is required to fill it. If the bone mass is insufficient in height, surgery is required to elevate the sinuses and insert bone grafts to increase bone mass.


Is All-On-4 dental implant suitable for seniors?

Elderly patients can also undergo All-on-4 full-mouth implant surgery. Essentially, the target group for All-on-4 full-mouth implants is the elderly. However, individuals with hypertension, heart disease, advanced age, or other chronic illnesses must undergo a professional medical diagnosis and risk assessment before starting All-on-4 surgery in Hong Kong to minimize any potential risks associated with the procedure.

All‑On‑4 全口植牙常見風險

植體失敗或鬆動：若骨質不足或癒合不良，植體可能無法與骨頭牢固結合。
感染或植體周圍炎：術後清潔不佳，容易導致牙齦紅腫、疼痛，甚至影響植體穩定。
神經或鼻竇損傷：下顎植牙靠近神經管，上顎植牙接近鼻竇，若定位不精準，可能造成麻木或鼻竇不適。
骨質流失：長期使用若清潔不足，齒槽骨可能逐漸萎縮，影響植體壽命。
假牙斷裂或鬆脫：全口假牙承受較大咬合力，若設計或材質不佳，可能出現斷裂或鬆動。
咬合不適：若假牙排列或高度不合適，可能造成咬合不平衡或顳顎關節不適。
術後腫脹與疼痛：屬於常見短期反應，通常在 1–2 週內逐漸緩解。
慢性疾病影響：糖尿病、骨質疏鬆或抽菸習慣會降低植牙成功率。
