Occlusal reconstruction with implant crown pair prostheses. Case report

Area of Science:

• Dental implantology
• Prosthodontics
• Biomaterials science

Background:

• Restoring occlusion in both dental arches presents challenges, particularly concerning implant stability and prosthetic longevity.
• Achieving precise parallelism of multiple dental implants is crucial for successful splinted crown restorations.
• Current techniques may require specialized instrumentation for accurate implant placement.

Observation:

• Occlusal reconstruction involved using splinted implant crown pairs for both maxillary and mandibular arches.
• Implant abutment pairs were luted to the implant crowns, and subsequently screwed and glued into the implant bodies.
• Approximately parallel pairs of implant bodies were achieved through precise alignment of abutment holes using a guiding device.

Findings:

• The described technique successfully facilitated the placement of parallel implant bodies for splinted crown restorations.
• The use of a precision guiding device ensured accurate angulation and positioning of implant components.
• This method allows for the reconstruction of occlusion with enhanced stability and predictability.

Implications:

• This technique offers a reliable method for complex full-mouth reconstructions using dental implants.
• Improved implant parallelism can lead to reduced stress on prosthetic components and enhanced long-term outcomes.
• The precision guiding device may simplify the surgical and prosthetic phases of implant-supported occlusal reconstruction.
