Zygomatic Implant

Description

Zygomatic Implant — Reliable Anchorage When Bone Grafting Is Not an Option

The IDL Zygomatic Implant provides a definitive solution for patients with severe atrophy of the posterior maxilla, where conventional implant placement is impossible due to insufficient alveolar bone. Anchored in the dense zygomatic bone rather than the maxillary alveolar ridge, it enables full-arch rehabilitation without preparatory grafting procedures.

Clinical Rationale

In cases of advanced maxillary resorption, traditional implant protocols require sinus augmentation or autogenous bone grafting — procedures that extend treatment time by 6 to 9 months and carry surgical risk. Zygomatic fixation bypasses these limitations: the implant engages cortical bone of the zygoma, providing immediate primary stability sufficient for immediate loading of a fixed full-arch prosthesis.

Design and Geometry

The implant body features an extended length ranging from 30 to 52.5 mm, allowing transit through the maxillary sinus and engagement with the zygomatic process. The apical portion has aggressive self-tapping threads for secure cortical engagement. The smooth polished collar in the intermediate zone reduces bacterial retention where the implant passes through the sinus cavity.

Grand Morse 16° Conical Connection

Zygomatic Implant uses the same Grand Morse 16° conical prosthetic platform as the rest of the IDL line. Surgeons can combine zygomatic fixation with standard implants in the anterior maxilla using a unified set of abutments and prosthetic components, simplifying the All-on-4 and All-on-6 hybrid protocols.

Hydrophilic RBM Surface

The Hydrophilic RBM surface treatment accelerates osseointegration in the dense but limited-contact zygomatic bone. Faster protein adsorption in the first 24–48 hours post-placement improves bone-to-implant contact in situations where surgical access restricts ideal preparation.

Material

Commercially pure titanium Grade 4 per ASTM F67. Grade 4 biocompatibility is particularly relevant for zygomatic fixation due to the implant’s proximity to the maxillary sinus membrane and infraorbital soft tissues.

Clinical Indications

– Severe posterior maxillary atrophy (Cawood-Howell Class IV–VI)
– Failed sinus augmentation or contraindications to grafting
– Full-arch immediate loading protocols (All-on-4, All-on-6, quad-zygoma)
– Post-oncological maxillary reconstruction
– Revision cases with extensive bone loss
