This case documents the implant-based rehabilitation of the upper jaw through the combined use of conventional and trans-sinus implants, performed by Dr. Luca Palumbo. The objective was to restore masticatory function in a patient with partial edentulism and reduced posterior bone volume.
Following thorough preoperative clinical and radiographic evaluation (Fig. 1), the treatment plan involved placing IS+ implants (BTK) in the anterior regions and BT-Rhyno implants (BTK) in the posterior areas using a trans-sinus approach. This strategy aimed to avoid major bone regeneration procedures and reduce overall treatment time.
The procedure was carried out under local anesthesia. A full-thickness flap was elevated to expose the maxilla. In the anterior regions, a conventional implant site preparation protocol was followed. The IS+ implants were placed (Fig. 2) with good primary stability due to the presence of sufficient residual bone.
In the posterior regions, where severe bone atrophy and maxillary sinus pneumatization were present, a trans-sinus approach was necessary. A lateral window was created to elevate the Schneiderian membrane (Fig. 3), a step performed with great care to preserve its integrity. The implant sites were then prepared with an inclined trajectory, crossing the sinus cavity and anchoring into the anterior basal bone. Two BT-Rhyno implants were placed (Fig. 4), specifically designed for trans-sinus placement and to provide stability even in cases of limited crestal bone height.
To complete the implant phase, localized bone regeneration was performed around the posterior implants using autogenous bone harvested with a bone scraper (Fig. 5). This aimed to fill any peri-implant gaps, promoting osseointegration and improving the long-term prognosis.
The surgery was completed in a single session, with minimal invasiveness and respect for soft tissues. The intraoperative images clearly document the key phases of the treatment: placement of anterior IS+ implants, trans-sinus positioning of BT-Rhyno implants, and the use of autogenous bone for final regeneration (Fig. 6).
This combined technique allowed for effective rehabilitation in a complex bone scenario, avoiding more invasive regenerative procedures and enabling a stable and predictable future prosthetic restoration.

BTK PRE-ANGLED IMPLANT LINES: Innovative design, uncompromising aesthetics
The Btk implant company, which for many years has focused its efforts on providing innovative solutions to dental surgeons for the resolution of severe atrophy, launches the Angled Zygomatic and Transinus Implant Line.
This represents an advanced solution for complex implant cases and, thanks to the pre-angled design with an external hexagon platform inclined at 24° for transinus implants and 55° for zygomatic implants, the restoration of the ideal prosthetic axis becomes a reality even in complex anatomical conditions:
- improving the aesthetic emergency
- simplifying the prosthetic connections
- reducing occlusal stress with a more physiological distribution of forces.
The bicortical anchorage and immediate primary stability allow a predictable approach, even in the absence of conventional bone volume.
An integrated solution, where surgery and prosthetics merge in a single technical gesture, for superior clinical results and optimal patient comfort.
The system also ensures well-defined prosthetic connections, for accurate alignment of the prosthesis.
With the Angled Line, BTK confirms its commitment to implant innovation.
Stability, aesthetics and surgical prediction. Beyond every limit.
