Case Summary 🔎
Patient Information
78 y/o, Male
Past Medical History: Hyperlipidemia
Introduction
This case presents the placement of an ALX-BT bone level implant in the #16 region of a 78-year-old male patient. The posterior maxilla exhibited poor bone quality (D443), which is typically associated with challenges in achieving sufficient primary stability for early loading.
Utilizing the ALX-BT implant, featuring an aggressive thread design and a narrow core, high primary stability was achieved with an insertion torque of 40 N·cm, even in soft bone conditions. An intraoral scan was performed the day after implant placement to obtain a digital impression for prosthetic fabrication.
Based on the favorable primary stability, early loading was performed at 2 weeks, and the final prosthesis was delivered. This case highlights the clinical effectiveness of ALX-BT implants in enabling predictable early loading in compromised bone quality of the posterior maxilla.
Case Presentation
1️⃣Pre-op
Pre-operative clinical and radiographic evaluation of the #16 region showing a missing tooth with sufficient residual bone height.
2️⃣Surgical Procedure
ALX-BT Drill Sequence
Flap elevation was performed to expose the alveolar ridge.
Ø2.5 × 10 mm drill
Ø3.5× 10 mm drill
Ø4.2 × 10 mm drill
An ALX-BT Ø6.5x10mm implant was placed with high primary stability, achieving an insertion torque of 40 N/cm.
A healing abutment was connected, followed by bone grafting around the implant.
