3D Guided Dental Implants, Straumann® & All-on-4 Complete Clinical Guide

The Digital Paradigm in Implantology: 3D CBCT & Computer-Guided Surgery

Long-term prosthetic longevity in modern oral implantology depends not merely on titanium metallurgy, but on precise prosthetically driven three-dimensional positioning within native alveolar bone. At One Clinic Istanbul, every 3D guided dental implant rehabilitation begins by superimposing low-dose Cone-Beam Computed Tomography (CBCT) DICOM volumes onto high-resolution intraoral optical STL scans.

Vital anatomical structures—including the inferior alveolar nerve canal, mental foramen, nasal floor, and maxillary sinus cavities—are mapped with sub-millimetric accuracy prior to surgery. Custom 3D-printed stereolithographic surgical guides allow keyhole, flapless fixture insertion without extensive mucoperiosteal incisions or sutures, significantly reducing post-operative edema, chair time, and soft-tissue remodeling.

Straumann® Roxolid® Alloy & SLActive® Hydrophilic Osseointegration

Biological success hinges on osseointegration—the direct structural and functional connection between living osteocytes and the micro-roughened implant surface. Swiss-engineered Straumann® systems address challenging bone anatomies through two clinically validated innovations:

• Roxolid® Titanium-Zirconium (TiZr) Metallurgy: Combining 85% titanium and 15% zirconium delivers markedly higher tensile and fatigue strength than cold-worked Grade 4 titanium, preserving cortical bone in narrow ridges and often avoiding invasive ridge augmentation.
• SLActive® Chemically Activated Surface: Stored in isotonic saline to prevent atmospheric hydrocarbon contamination, its hydrophilic nanostructure immediately attracts blood proteins and fibrin networks, shortening the critical stability dip from 6–8 weeks down to 3–4 weeks.
• Bone-Level Tapered Apical Geometry: Achieves high primary mechanical engagement even in freshly extracted sockets or softer D3/D4 maxillary trabecular bone.

Full-Arch Biomechanics: All-on-4® and All-on-6 Rehabilitation

For edentulous patients or patients with failing dentition and posterior bone resorption, the All-on-4 full-arch implant protocol restores fixed masticatory function without bilateral sinus floor elevation. Two axial anterior implants work synergistically with two posterior implants tilted between 30° and 45°, engaging dense anterior cortical bone while eliminating destructive distal cantilevers.

When primary insertion torque reaches or exceeds 35 Ncm across the multi-unit abutments, a screw-retained provisional fixed bridge is delivered within 48 to 72 hours—ensuring patients never leave the clinic without fixed teeth.

Definitive CAD/CAM Zirconia Prosthetics & Occlusal Harmony

Following a 3-to-4-month biological osseointegration phase, patients return for definitive prosthetic fabrication. Using digital photogrammetry and virtual articulation, monolithic or multi-layered zirconia crowns and bridges are milled with passive multi-unit seating. Across all comprehensive dental treatments at One Clinic, canine-guided or mutually protected occlusion is calibrated digitally to safeguard implants against parafunctional overload.
