The All-on-Four protocol is a surgical-prosthetic approach that aims to restore full-arch function using only four titanium implants supporting a fixed bridge.
Clinical outcomes for any surgical procedure vary between individuals. It is recommended that you consult your clinician for detailed information before proceeding.

Titanium Implants
For full-arch restoration
Clinical Steps
From assessment to restoration
Surgical Session
All four implants placed in one session
Osseointegration Period
Varies by individual bone structure
01
Following an intraoral examination and medical history review, 3D cone beam CT (CBCT) provides three-dimensional analysis of bone volume, nerve canals and vascular anatomy.
02
CT data is transferred to planning software where the position, angle and depth of the four implants are determined virtually. A surgical guide may be produced by 3D printing or CAD/CAM where indicated.
03
All four implants are placed in a single session under local anaesthesia. The two posterior implants are positioned at an angle. Sedation is considered based on clinical assessment and patient preference.
04
Where implant stability is clinically confirmed, a temporary fixed prosthesis may be placed on the day of surgery or shortly after. The timing of this stage depends on individual conditions.
05
Once osseointegration is confirmed radiologically, a permanent zirconia or high-strength acrylic bridge is delivered. Maintenance method and review intervals are explained in detail.
This flow is intended for patient education; sequence, additional preparation and review intervals are adjusted according to individual examination findings.
01
Clinical Assessment
All-on-Four requires a thorough clinical assessment for patient selection. In addition to examination findings, medical history, medication use, smoking habits and bone structure are key components of this evaluation. The topics below summarise the main areas addressed during the appointment; the final decision can only be made by the clinician.
02
Digital Planning Infrastructure
Cone beam computed tomography (CBCT) provides three-dimensional visualisation of bone volume, nerve canals and vascular anatomy. This data is transferred to planning software where implant positions are determined virtually. A surgical guide supports accurate placement of the planned positions during surgery.
03
Clinical Approach
All-on-Four planning is shaped by detailed evaluation of examination findings, imaging, patient expectations and alternative options. Before a treatment decision is made, the patient is comprehensively informed about the process, potential risks and alternative protocols.
04
Post-treatment Care
The long-term course of All-on-Four treatment depends on post-surgical care and regular clinical review. The soft diet and oral hygiene protocol specified for the initial weeks should be followed carefully.
All-on-Four uses four implants, All-on-Six uses six. Both protocols offer different load distribution and support points. Which is recommended depends on bone structure, anatomical conditions and examination findings as assessed by the clinician.
Angled posterior implant placement may reduce the need for posterior bone grafting in many cases. However, where bone volume is insufficient, an additional procedure may be required. This decision is based on 3D imaging findings.
Same-day discharge is possible in many cases. If sedation was administered, it is recommended that you leave with a companion. Your personal discharge plan will be explained by the clinician.
It is used until the osseointegration process is complete. This period varies according to individual bone structure and healing response; the exact timeline is shared following examination findings.
The underside and surrounding area of the bridge are cleaned with a specialised interdental brush, single-tuft brush or water flosser. The clinician will explain the method and products appropriate to your oral anatomy in detail.
Uncontrolled diabetes, active bone disease or certain medications affecting the immune system may influence the assessment. The suitability decision is made following a comprehensive examination and medical history review.
