GDT PTR is a bone level Pterygoid Implant designed for use in the posterior maxilla and pterygomaxillary regions, where conventional implant placement is limited due to poor bone quality or sinus proximity. Its geometry is suited for cases requiring extended anchorage, such as restoration of the atrophic maxilla or full-arch rehabilitations.

This implant is manufactured from titanium grade 5 (Ti-6Al-4V ELI) and features a self-tapping body with a dual-thread design. The apical section features sharp threads that cut through dense cortical bone, while the middle section is shaped to compress trabecular bone, enhancing initial stability and load distribution. The coronal section includes a smooth, polished collar designed to minimize bacterial accumulation and support soft tissue health by reducing mechanical irritation at the crest. 

For optimal results in PTR implant placement, we advise utilizing our Surgical Kit designed specifically for Basal/Cortical Implants.

GDT implants are made of Titanium alloy Ti-6Al-4V ELI. This material combines properties such as low specific weight, high strength to weight ratio, very high corrosion resistance, and excellent general biocompatibility.

Ti-6Al-4V ELI is very similar to Ti-6Al-4V, except that Ti-6Al-4V ELI contains reduced levels of oxygen, nitrogen, carbon, and iron. ELI is short for “Extra Low Interstitials”, and these lower interstitials provide improved ductility and better fracture toughness for the material. Ti-6Al-4V ELI has proven to be highly successful in the fabrication of dental implants

RBM Surface Treatment

RBM surface is rough and hydrophilic. This surface treatment is designed to roughen the implant surface without leaving the residual embedded blast particles or debris in the treated substrate.

To gain the desired roughening the implant is blasted with suitable hardened particles of Hydroxyapatite (beta-tricalcium Phosphate, Alpha Tcp, TTcp, and Calcium Phosphate (CPP) and then subsequently dissolved from the surface with a defined passivation treatment.

Surface roughness between Ra 1.2 - 1.5 is consistently achieved.The result is a rougher implant surface than traditional acid etches treatment providing a greater surface area for osseointegration, improved retention characteristics, increased biological fixation, and maximizing implant-to-bone contact.
The shape of the implant is made for simple and secure work and improving the osseointegration level.

The RBM surface treatment is made to improve the healing process and tissue growth around the implant, with no worries of abruption or disintegration.

Drilling Protocol

* The suggested drilling protocol is provided as a general recommendation only and should not replace the clinician’s professional judgment.

GDT Dental Implants provides a lifetime warranty on eligible dental implants manufactured under the GDT brand, subject exclusively to the terms, conditions, limitations, and exclusions set forth in the official Warranty Policy.

Where applicable and approved by GDT, the warranty is limited to replacement of the qualifying implant or related GDT-manufactured component in cases such as verified manufacturing defect, implant fracture, contamination in the original sealed packaging, or another qualifying product-related failure that meets the policy requirements.

Warranty coverage does not replace clinical judgment, proper case selection, professional handling, or compliance with accepted dental protocols. Please review the full Warranty Policy for complete details regarding eligibility, required documentation, exclusions, regional availability, and claim procedures.
