How to Solve a Critical Case with Insufficient Occlusal Space?

At Lemei Dental Lab, we understand that complex restorative cases demand not just technical skill, but also innovative thinking and a deep commitment to restoration longevity. A common challenge we help dentists overcome is the risk of fracture in bridges where the occlusal space is limited and the biting force is high.

Today, we’re sharing a recent case that perfectly illustrates our problem-solving approach, showcasing why we are recognized as a trusted dental lab in China.

Case Overview:

Restoration: #34-36 monolithic zirconia implant-supported bridge.

Implants: Placed at #34 and #36 with custom abutments.

Pontic at #35

The Critical Challenge: The patient presented with insufficient occlusal space combined with heavy masticatory forces. A standard monolithic zirconia bridge in this scenario carried a significant risk of fracture at the connector areas, potentially leading to restoration failure.

Without a robust solution, this case could have resulted in a compromised restoration and patient dissatisfaction.

Lemei Dental Lab Solution: Engineering Strength and Durability

Our team of 20+ expert dental technicians analyzed the case and devised a two-part strategy to ensure absolute strength and clinical success.

1. Reinforced Connector Design

We strategically increased the dimensions of the connectors between #34-35 and #35-36. We ensured that each connector area exceeded 4mm in both height and width (4x4mm). This fundamental step is crucial for distributing stress and preventing the common failure point of connector fracture.

2. The Titanium Bar Reinforcement

To elevate the bridge's resilience to the next level, we designed a custom titanium (Ti) bar framework. This high-strength Ti bar was meticulously designed to be embedded within the monolithic zirconia bridge. This innovative hybrid approach creates a "backbone" for the restoration, dramatically increasing its overall fracture resistance and ability to withstand high occlusal loads without compromising on the aesthetics of zirconia.
