FULL ARCH IMPLANT
The sites for each jaw, the bite on both sides, and the provisional prosthesis plan. When restoring the upper and lower jaws together, these three are decided together.
Full Arch
A full-mouth implant is a treatment that restores the chewing function and bite of an entire jaw when all teeth are missing or the remaining teeth are hard to keep. It is also called a total implant. When treating the upper and lower jaws together, you need to decide not only the bone condition of each jaw but also the bite on both sides and the plan for using a provisional prosthesis. Yeonhap Dental Clinic's basic design is a fixed prosthesis that divides 12 artificial teeth per jaw into three segments, with at least 6 implants in the lower jaw and at least 7 in the upper jaw.
CT Planning
At the first consultation, we look at the condition of both jaws with 3D CT and an oral examination and make the treatment plan.
Upper & Lower
We look together at the bone condition of each jaw, the bite, and the provisional prosthesis plan to set the surgery schedule.
In the lower jaw, we look at whether the bone above the nerve canal at the molar sites is under 5 mm; in the upper jaw, we look at whether implants can be placed at the front tooth sites and whether a sinus lift is needed. The details of the site judgments are in the lower jaw guide and the upper jaw guide, and the results for both jaws are combined to decide the overall design.
When only one jaw is treated, it is matched to the opposing teeth, but when upper and lower are done together, the chewing height and tooth arrangement are decided from the start based on both jaws. At the provisional prosthesis stage, we try out the bite in advance and reflect it in the final prosthesis.
If four implants in the lower jaw and six in the upper jaw with a diameter of 4 mm, a length of 8.5 mm, and an initial stability of 30 Ncm or more are secured and the connection design is suitable, we attach the provisional prosthesis within the same day to 1 week. For a jaw that does not meet the conditions, you use a temporary denture in the meantime, and in an upper jaw where a sinus lift is done together, we do not attach it immediately.
Upper vs Lower
The surgery schedule is set by the condition of each jaw, and the timelines below are estimates from placement to the final prosthesis.
We decide the design for both jaws on the first-visit CT, and if conditions allow, we place on the day of extraction; if not, we wait and then place. If conditions allow, we attach a provisional prosthesis, and after the implants have bonded to the bone, we make the final prosthesis. Whether to do both jaws on the same day or separately is decided by your condition and consultation.
We expect about 4 months from placement to the final prosthesis for the lower jaw and about 4-8 months for the upper jaw, and the two jaws may finish at different times. If a sinus lift is done first, we explain the total timeline separately from the first surgery, and the wait after extraction is separate.
Before Visit
Bring them if you have them. If not, we will calculate from CT on the first day.
Basic design: A three-segment fixed prosthesis that divides 12 artificial teeth per jaw into three segments, with at least 6 implants in the lower jaw and at least 7 in the upper jaw. All-on-X uses 4 in the lower jaw and 6 in the upper jaw (Full-Arch Implant (All-on-X) Guide). Sites: In the lower jaw, if the bone above the nerve canal at the molar sites is under 5 mm, we consider All-on-4 at the four front sites, and in the upper jaw, if placement at the front tooth sites is difficult, we consider All-on-6. The judgment for each jaw is in the Lower Jaw Implant Sites Guide and the Upper Jaw Implant Sites Guide. Provisional prosthesis: If there are qualifying implants, 4 in the lower jaw and 6 in the upper jaw, we attach it within the same day to 1 week. If not, we repair your existing denture or use a new temporary denture, and in an upper jaw where a sinus lift is done together, we do not attach it immediately. Timeline: About 4 months from placement to the final prosthesis for the lower jaw and about 4-8 months for the upper jaw. If a sinus lift is done first, we explain the total timeline separately from the first surgery. Estimates by starting point are in the timeline guide, and the conditions for placing on the day of extraction are in the Immediate Implant Guide.
The number of implants, provisional prosthesis specifications, and timeline are Yeonhap Dental Clinic's standards. We referred to the consensus statement on implant loading protocols (Gallucci 2014) for the initial stability conditions for immediate loading of a full arch, and NHI coverage for the completely edentulous follows the Health Insurance Review and Assessment Service notice and Ministry of Health and Welfare announcements. There is no fixed order for which jaw is done first or whether both jaws are operated on the same day; it is decided by your condition and consultation. For this reason, when treating the upper and lower jaws together, Yeonhap Dental Clinic looks at the CT of both jaws together at the first consultation and decides the sites, the bite, and the provisional prosthesis plan at once. References: Gallucci 2014, consensus statement on implant loading protocols · Health Insurance Review and Assessment Service, recognition criteria for dental implants (Notice No. 2025-23) · Ministry of Health and Welfare, results of the Sept. 8, 2026 Health Insurance Policy Deliberation Committee (expanded dental coverage) The details of the implant sites for each jaw and the conditions for choosing All-on-X are in the guides under the related links below. Treatment results may vary depending on each person's oral condition. The applicable methods and course of healing vary from person to person depending on the remaining teeth, bone, and general health.
