Description
A prosthodontic procedure using four strategically placed dental implants to support a fixed, full-arch prosthesis loaded within 24–48 hours of surgery, enabling immediate function and aesthetics.
Main Uses
All-on-4 is an immediate-load full-arch dental rehabilitation technique using four strategically angled implants to support a fixed prosthesis. Primary clinical uses include: 1) Restoring edentulism or near-total tooth loss in maxilla and/or mandible, 2) Providing functional and aesthetic rehabilitation in a single day (same-day teeth), 3) Avoiding bone grafting in patients with moderate alveolar atrophy via tilted posterior implants, 4) Serving as definitive treatment for patients with compromised medical status who cannot undergo prolonged staged implant therapy, 5) Improving oral health-related quality of life (OHRQoL), masticatory efficiency, and phonetics in geriatric or oncologic rehabilitation.
Normal Range
All-on-4 is not a laboratory or diagnostic medical test with numerical values; it is a surgical-dental prosthetic treatment protocol. Therefore, there is no 'normal range' of quantitative biomarkers, lab values, or physiological parameters associated with All-on-4 itself. Clinical success metrics (e.g., implant survival rate >95% at 5 years, marginal bone loss <1.5 mm in first year, prosthetic stability score ≥9/10 on occlusal load testing) are outcome-based and assessed clinically/radiographically—not via numeric reference intervals.
Low Values - Possible Causes
N/A — All-on-4 is not a measurable biomarker or lab parameter; 'low values' do not apply. However, clinical failure indicators (e.g., early implant mobility, excessive bone loss <1 mm/year, or prosthetic fracture) may stem from: 1) Inadequate primary implant stability (<35 Ncm insertion torque), 2) Poor bone quality (D4 bone density), 3) Uncontrolled systemic conditions (e.g., unmanaged diabetes, severe osteoporosis), 4) Smoking (>10 cigarettes/day), 5) Non-compliance with postoperative protocols (e.g., premature loading, poor oral hygiene).
High Values - Possible Causes
N/A — All-on-4 is not a quantifiable test with high/low values. However, elevated risk factors for complications include: 1) Excessive occlusal forces (>200 N on posterior segments), 2) High plaque index (>2.5), 3) Elevated serum HbA1c (>8.5%) in diabetic patients, 4) Elevated salivary IL-6 or TNF-α (indicating chronic peri-implant inflammation), 5) Radiographic evidence of >2.0 mm marginal bone loss within first year — though these are secondary biomarkers, not All-on-4 values.
