Use of wide-diameter and standard-diameter implants to replace single molars: two case presentations

Area of Science:

• Dental Implantology
• Restorative Dentistry
• Biomaterials

Background:

• Modern esthetic dentistry aims to replicate natural tissues for optimal function and aesthetics.
• Increasing patient esthetic demands drive advancements in surgical techniques and dental knowledge.
• Restoring molar regions with dental implants presents challenges due to anatomical factors and bone quality.

Observation:

• Two clinical cases illustrate methods for replacing a single missing molar using dental implants.
• Case 1: A mandibular first molar (FDI 46) restored with a porcelain-fused-to-metal crown on two standard-diameter implants in a root-analog position.
• Case 2: Mandibular first molars (FDI 36 and 46) replaced with porcelain-fused-to-metal crowns on wide-diameter implants.

Findings:

• Both single wide-diameter implants and two standard-diameter implants provide greater surface area than a single standard implant.
• These approaches offer enhanced biomechanical properties for molar region restorations.
• The choice between single wide-diameter or dual standard-diameter implants depends on available space and clinical considerations.

Implications:

• These findings suggest improved outcomes for molar implant restorations using either wide-diameter or dual implant solutions.
• Further long-term clinical data are necessary to establish definitive recommendations for private practitioners.
• The study highlights the ongoing evolution of dental implant techniques for complex restorative cases.
